ICS NO. 75.200;77.140.75
Not to be reproduced without the
permission of BIS or used as STANDARD
Last date for receipt of

FORWORD
This draft standard has been formulated by amalgamating IS 1978:1982
‘Specification for line pipe (second revision)’ and IS 1979:1985 ‘Specification for
high-test line pipe (second revision). IS 1978 was first published in 1961 and was
subsequently revised in 1971 and 1982 whereas IS 1979 was first published in 1961
and was subsequently revised in 1971 and 1985. Since these are related standards,
it was decided to amalgamate these two into one in line with API 5L 2004
Specification for line pipe, American Petroleum Institute. After publication of this
standard IS 1979 shall be withdrawn.
The sizes used in this revision are dimensionless designations, which are derivd
from the specified outside diameter as measured and provide a convenient method
of referencing pipe size within the text and tables. Pipe sizes 23/8 and larger are
expressed as integers and fractions; pipe sizes smaller than 23/8 are expressed to
three decimal places. These sizes replace the `size designation’ and the `nominal
size designation’ used in the IS 1978 and IS 1979.
This draft standard contains clause 3.2.1, 3.2.2, 5.6, 7.2, 8.1, 8.1.2, 9.2 b), 9.3.4,
15.1, 16.1, 18.2, 19.1, 19.3, A-3.3 b), A-3.4, A-6.3, D-1.2, which call for agreement
between the purchaser and the manufacturer.
In the preparation of this draft standard assistance has been derived from the
following publication:
API 5L 2004 Specification for line pipe, American Petroleum Institute.
For the purpose of deciding whether a particular requirement of this standard is
complied with, the final value, observed or calculated, expressing the result of a test
or analysis, shall be rounded off in accordance with IS 2: 1960 ‘Rules for rounding off
numerical values (revised). The number of significant places retained in the rounded
off value should be the same as that of the specified value in this standard.

8.2.2.2 Non-expanded electric welded pipe in grades higher than YSt 172 (A25) and
nonexpanded laser welded pipe smaller than 323.9 mm OD, produced in multiple
lengths—The manufacturer may elect to retest each end of each individual length if
any test fails. Two additional lengths shall be taken from the coil in which pipe is
rejected in flattening test. The retests of each end of two pipes shall be tested with
the weld alternatively at 00 and 900.
8.2.2.3 Cold-expanded electric welded pipe in grades higher than YSt 172 (A25); all

of pipe from each lot of 50 lengths or less of each combination of specified outside
diameter, specified wall thickness, and grade of finished helical seam pipe containing
skelp end welds. The test specimens shall not contain repair welds.
8.4.2 One face bend and one root bend specimen, both conforming to Fig 4 shall be
bent approximately 1800 in jig substantially in accordance with Fig. 5. For any
combination of diameter, wall thickness and grade, the maximum value of jig
dimension A in Fig 5 may be calculate by the formula given. The manufacturer shall
use a jig based on this dimension or a smaller dimension at his option. However to
minimize the number of jigs required, standard values for dimension A have been
selected for pipe size of 323.9 mm OD and larger. These values are listed for each
size, wall thickness and grade in Annex C. For intermediate grades or specified wall
thickness, the next smaller standard value for dimension A shall be used. When the
dimension A is greater than 228.6 mm, the length of the specimen required to
contact the male die need not exceed 228.6 mm. For pipe with wall thickness over
19.1 mm, a reduced wall specimen as shown in Fig 5 may be used at the option of
the manufacturer. Reduced wall specimens shall be tested in a jig with the A
dimension calculated for pipe of wall thickness 19.1 mm of the appropriate size and
grade.
8.4.3 The specimen shall not (a) fracture completely, (b) reveal any crack or rapture
in the weld metal greater than 3.2 mm in length regarding of depth, and (c) reveal
any crack or rapture in the parent metal, the heat affected zone or the fusion line
longer than 3.2 mm and deeper than 12.5 percent of the specified wall thickness;
except cracks which occur at the edges of the specimen and which are less than 6
mm long. These shall not be the cause for rejection in (b) and (c) regardless of
depth. If the fracture or crack in the specimen is caused by a defect or flaw, the
specimen may be discarded and a new specimen substituted.
8.4.4. Retests – If one or both of the guided bend specimens fail to conform to the
specified requirements, the manufacturer may elect to repeat the tests on specimens
cut from two additional lengths of pipe from the same lot. If such specimens
conforms to the specified requirements ,all the lengths in the lot shall be accepted,
except the length initially selected for test. If any of the retest specimens fail to pass
the specified requirements, the manufacturer may elect to test specimens cut from
the individual length remaining in the lot. The manufacturer may also elect to retest
any length, which has failed to pass the test by cropping back and cutting two
additional specimens from the same end. If the requirements of the original test are
met by both of these additional tests, this length shall be acceptable. No further
cropping and retesting is permitted. Specimens for retests shall be taken in the same
manner as specified in 8.4.2

absorbed energy for each heat based on full size specimens shall be 27 J for
transverse specimens or 41 J for longitudinal specimens, whichever is applicable
per Table 7.
8.5.1.2 For all grades, the shear area of each specimen shall be reported for each
heat.
8.5.1.3 For grade YSt 552 (X80) only, the required minimum all-heat average
absorbed energy for the entire order item, based on full size Charpy specimens shall
be 68 J (50 ft-lb) for transverse specimens; or 101 J for longitudinal specimens,
whichever is applicable for Table 7. If the all-heat average of the does not meet the
applicable requirement, the manufacturer shall be responsible for the replacement of
heats to bring the average up to the required level.
8.5.1.4 For grade YSt 552 (X80) only, the required minimum shear area shall be
either 40 percent for each heat and 70 percent for the all-heat average of order
based on the charpy test, or 40 percent for each heat and 60 percent for the all-heat
average on the drop weight tear test as given in Annex A. The drop-weight tear test
is applied for welded pipe in size 508.0 mm or larger. If the all-heat average of the
order does not meet the required percentage of shear area, the manufacturer shall
be responsible for the replacement of heats as necessary to bring the average up to
the required level.
8.5.2 Retests – In the event that a set of Charpy test specimen fails to meet the
acceptance criteria, the manufacturer may elect to replace the lot of material
involved or alternatively to test two more lengths from that lot. If both of the new tests
meet the acceptance criteria, then all pipes in that heat, with the exception of the
original selected length, shall be considered to meet the requirement. Failure of
either of the two additional tests shall require testing of each length in the lot for
acceptance.
8.5.3 Supplementary Fracture Toughness Tests – In addition to the requirements in
8.5.1, when so specified in the purchase order, the manufacturer shall conduct
fracture toughness tests in accordance with supplementary requirement SR 5 and
SR-6 (see Annex A) or any combination of these, and shall furnish a report of
results showing compliance with the specified supplementary requirements.
8.6 Metallographic Examination – For PSL 1 electric welded pipe in grades higher
than YSt 290 (X42), for PSL 2 electric welded pipe in all grades, and for laser welded
pipe in all grades, full body normalized pipe excluded, compliance with the
requirement in 3.2 and 3.4 to heat treat the entire heat affected zone shall be
demonstrated by metallographic examination of a weld cross section. Such
examinations shall be performed at least once per operating shift (12 hours
maximum) and whenever changes of grade, diameter, or wall thickness are made

manufacturer, pipes shall be furnished in single random lengths or double random
lengths as specified by the purchaser. Tolerances on the length shall be as specified in
22
Doc: MTD 19 (4672) W
Table 13. For threaded-and-coupled pipe, the length shall be measured to the outer
face of the coupling. The length of threaded-and-coupled pipe may be determined
before the couplings are attached, provided that proper allowance is made for the
length of the couplings. Each length of pipe shall be measured, except that pipe made
in lengths that are uniform within 0.03 m need not be individually measured, provided
that the accuracy of the length is verified at least once per 4 hours per operating shift.
The accuracy of length measuring devices for lengths of pipe less than 30 m shall be +

PIPE ENDS
10.1 General – The pipe ends shall be plain, threaded, belled or prepared special
coupling. Helical seam pipe shall not be threaded. The inside and outside edges of the
ends of all pipes shall be free of burrs.
10.2 Threaded Ends (PSL 1 Only) – Threaded ends shall conform to the threading,
thread inspection and gauging requirements specified in API Std 5B. One end of each
length of threaded pipe shall be provided with a coupling conforming to the
requirements of 12, in effect at the date of manufacture of each coupling (see Note 1)
and the other end with thread protection conforming to the requirements of 17.2.
Coupling shall be screwed onto the pipe handling-tight (see Note 2), except that they
shall be applied power-tight if so specified on the purchase order. A thread compound
shall be applied to cover the full surface of either the coupling or pipe engaged thread
before making up the joint. All exposed threads shall be coated with this thread
compound. Unless otherwise specified on the purchase order, the manufacturer may
use any thread compound that meets the performance objectives set forth in API RP
5A3. a storage compound of distinct colour may be substituted for this thread
compound on all exposed threads. Whichever compound is used shall be applied to a
surface that is clean and reasonably free of moisture and cutting fluids.
NOTE 1 — Unless otherwise specified on the purchase order, it is not mandatory that both the pipe and coupling of each
threaded and coupled product be manufactured to the same edition of this specification.
NOTE 2 -- Handling-tight shall be defined as sufficiently tight that the coupling cannot be removed except by using a
wrench. The purpose of making up couplings handling-tight is to facilitate removal of the couplings for cleaning and
inspecting threads and applying fresh thread compound before laying the pipe. This procedure has been found necessary
to prevent thread leakage, especially in gas lines, because manufacturer-applied couplings made up power-tight,
alt6hough leak-proof at the time of makeup, may not always remain so after transportation, handling and laying

supplied on the order. The specimens shall be tested at 100C or at a lower temperature
as specified by the purchaser. The average shear value of the fracture appearance of
the three specimens shall not be less than 60 percent, and the all-heat average for each
order per diamenter size and grade shall not be less than 80 percent.
A-5.2
If the average of the three specimen from one heat does not meet the
requirement of 60 percent shear, the manufacturer may elect to repeat the tests on
specimens cut from two additional lengths of pipe from the same heat. If such
specimens conform to the specified requirements, all the lengths in the heat shall be
accepted except the length initially selected for test. If any of the retest specimens fail
topass this specified retest requirement, the manufacturer may elect to test specimens
cut from the individual lengths remaining in the heat.
A-5.3
The average shear value for a heat shall be the average of the original three
specimens if the average is 60 percent or more; the combined average of the retest
specimens , provided the average of each group of three specimens is 60 percent or
more; or, in the event individual lengths are tested, the combined average of all groups
of three specimens that meet 60 percent. The all-heat average value is the combined
average of the average shear value for each of the heats supplied for the order item.
A-5.4 If the all-heat average of the order does not meet the requirement of 80 percent
shear, the manufacturer shall be responsible for replacement of such heats as may be
necessary to bring the average shear area up to 80 percent.
A-5.5
Alternatively, the manufacturer may elect to test two or more additional lengths
from one or more of the heats. In determining the new heat average, the original test
values may be discarded if the pipe length represented is rejected or the three or more
individual values are averaged. In any case, the new test values shall be incorporated
into the value for the heat.

impact test specimens in accordance with IS 1757:1988 except as modified herein and
the requirements specified in A-4.1, except the test frequency shall be as indicated in A5.2. The purchaser shall specify, in whole numbers both the test temperature and the
minimum average absorbed energy for full-size specimens. Specimens used for shear
area determination according to A-4 may be additionally used for the determination of
absorbed energy.
A-6.2 Three transverse specimens representing one test shall be taken one length of
pipe from each inspection per heat produced. An inspection lot shall consist of pipe that
is made to the same size and same specified wall thickness by the same process and
under the same manufacturing conditions.
A-6.3 For acceptance, the average absorbed energy of the three individual specimens
from a length shall not be less than the full-size value specified by the purchaser. In
addition, the lowest individual reading of the three specimens shall not be less than 75
percent of the specified value. When sub-size specimens are used, the individual
readings and the average of the three readings are divided by the ratio of the specimen
thickness tested to the full-size specimen thickness and compared with the full-size
acceptance criteria. When flattened specimens are used, each of the three individual
impact energy readings shall be multiplied by 10 and divided by the actual measured
specimen width, in millimeter. These results, and the average of the three results, shall
meet the specified absorbed energy acceptance criteria for full-size specimens.
A-6.4 Specimens showing material defects or defective preparation, whether observed
before or after breaking, may be discarded and replacements shall be considered
original specimens. In the event a set of test specimens fails to meet the acceptance
criteria, the manufacturer may elect to replace the lot of material involved or
alternatively to test two more lengths from the same lot. If both of the new tests meet
the acceptance criteria, then all pipe in the lot with the exception of the original selected
length shall be considered to meet the requirement . Failure of either of the two
additional tests shall require testing of each length in the lot for acceptance.

END LOAD COMPENSATION FOR HYDROSTATICTEST PRESSURESIN EXCESS OF 90%
OFSPECIFIEDMINIMUM YIELD STRENGTH (NORMATIVE)
(By agreement between the purchaser and themanufacturer, the following method may be used
to determine the hydrostatic test pressure).
H – 1 As a measure to prevent distortion when testing at pressures equivalent to stresses in
excess of 90% of specified minimum yield strength, the manufacturer may bv apply a calculation
to compensateforthe forces applied to the pipe end that producea compressive
longitudinalstress. The calculation in this appendix is based on Barlow’s equation (see 9.4.3)
modified by a factor based on the Maximum Shear Theory (seenote).The calculation may be
appliedonly when testing in excess of 90% of the specifiedminimum yield strength. In no case
may the gage pressurefor testing be less than that calculated using Barlow’s equation at 90% of
specified minimum yield strength.
NOTE – The calculation isan approximation of the effective hoop stress (SE), which is
practicalfor application under mill pipe testing conditions. Other calculations provide closer
approximations of effective hoop stress but are complexand therefore impracticalfor application.
H.2 The test pressure calculated shall be rounded to the nearest 100 kpa.
H.3 The hydrostatic test pressure compensated for pipe end loading shall be calculated
according to the following equation:
U.S. Customary Unit Equation:
PRAR
SE - ------------AP
P1 = ---------------------D A1
---- - ---2t AP
SI Unit equation:
P RA R
SE - ------------AP
P1 = 1000 ---------------------D A1
---- - ---2t AP
where:
A1 = internal cross – sectional area of pipe,
68
Doc: MTD 19 (4672) W
AP = corss-sectional area of pipe wall,
AR = cross-sectional area of ram, mm2
A1 = hydrostatic test pressure in kPa
AR = internal pressure on end-sealing ram,psi kPa
AE= effective hoop[ stress in Mpa equal toa percentaveof the specified
minimum yield strength
D = specified outsidediameter, (mm)
t = specified wall thickness, (mm)
H.4 The above equation may be manipulated algebraically to provide calculation in other terms
appropriate to the manufacturer’s testing facility.
H.5 Appropriate techniques for the control of effective hoop stress based on measurements of
internal pipe and ram pressures varyu according to hydrotester system design. The
manufacturer shall provide a control technique appropriate to his installation.

Inspection lots consist of Pipe that are made to the same size and the same specified wall thickness by the same process and under the same
manufacturing conditions.
b
In addition, over the duration of the pipe production run, each heat steel is to be tested at least once
c
The cold expansion percentage is designated by the manufacturer, and is derived using the designated before-expansion outside diameter or
circumference and the designated after-expansion outside diameter or circumference. An increase or decrease in the cold expansion percentage of
more than 0.2 percentage point (for example, a change form 1.0% cold expansion to <0.8% or > 1.2%) constitutes a change in inspection lot.
d
In addition, over the duration of the pipe production run, pipe produced by each welding machine is to be tested at least once per week.
e
For each test of double seam pipe, both weld seams in the pipe selected to represent the inspection lot are to be tested
f
Applies only to finished hetical seam pipe containing skelp end welds

1.This table provides a description of the required specimens and the relationship between pipe dimensions and acceptable specimens. The size
limits for transverse specimens shown are based upon the use of nonflattened, Taperes end, test specimens.
2. All specimen dimension limits include machining tolerances.
3. Pipe in size and specified wall thickness combinations not covered by this table are not required to be tested

Pipe that has this combination of specified outside diameter and specified thickness is special plain-end pipe; other combinations given in this table are regular plain-end
pipe. Pipe that has a combination of specified wall thickness that is intermediate to the tabulated values is considered to be special plain-end pipe if the next lower tabulated
value is for special plain-end pipe; other intermediate combinations are considered to be regular plain-end pipe. (See Table 11 for the applicable weight tolerance.)

ANNEX H
END LOAD COMPENSATION FOR HYDROSTATICTEST PRESSURESIN EXCESS OF 90%
OFSPECIFIEDMINIMUM YIELD STRENGTH (NORMATIVE)
(By agreement between the purchaser and themanufacturer, the following method may be used
to determine the hydrostatic test pressure).
H – 1 As a measure to prevent distortion when testing at pressures equivalent to stresses in
excess of 90% of specified minimum yield strength, the manufacturer may bv apply a calculation
to compensateforthe forces applied to the pipe end that producea compressive
longitudinalstress. The calculation in this appendix is based on Barlow’s equation (see 9.4.3)
modified by a factor based on the Maximum Shear Theory (seenote).The calculation may be
appliedonly when testing in excess of 90% of the specifiedminimum yield strength. In no case
may the gage pressurefor testing be less than that calculated using Barlow’s equation at 90% of
specified minimum yield strength.
NOTE – The calculation isan approximation of the effective hoop stress (SE), which is
practicalfor application under mill pipe testing conditions. Other calculations provide closer
approximations of effective hoop stress but are complexand therefore impracticalfor application.
H.2 The test pressure calculated shall be rounded to the nearest 100 kpa.
H.3 The hydrostatic test pressure compensated for pipe end loading shall be calculated
according to the following equation:
U.S. Customary Unit Equation:
PRAR
SE - ------------AP
P1 = ---------------------D A1
---- - ---2t AP
SI Unit equation:
PRAR
SE - ------------AP
P1 = 1000 ---------------------D A1
---- - ---2t AP
130
Doc: MTD 19 (4672) W
where:
A1 = internal cross – sectional area of pipe,
AP = corss-sectional area of pipe wall,
AR = cross-sectional area of ram, mm2
A1 = hydrostatic test pressure in kPa
AR = internal pressure on end-sealing ram,psi kPa
AE= effective hoop[ stress in Mpa equal toa percentaveof the specified
minimum yield strength
D = specified outsidediameter, (mm)
t = specified wall thickness, (mm)
H.4 The above equation may be manipulated algebraically to provide calculation in other terms
appropriate to the manufacturer’s testing facility.
H.5 Appropriate techniques for the control of effective hoop stress based on measurements of
internal pipe and ram pressures varyu according to hydrotester system design. The
manufacturer shall provide a control technique appropriate to his installation.
