IPS-C-PI-270(2)
FOREWORD
The Iranian Petroleum Standards (IPS) reflect the
views of the Iranian Ministry of Petroleum and are
intended for use in the oil and gas production
facilities,
oil
refineries,
chemical
and
petrochemical plants, gas handling and processing
installations and other such facilities.
IPS is based on internationally acceptable
standards and includes selections from the items
stipulated in the referenced standards. They are
also supplemented by additional requirements
and/or modifications based on the experience
acquired by the Iranian Petroleum Industry and
the local market availability. The options which
are not specified in the text of the standards are
itemized in data sheet/s, so that, the user can select
his appropriate preferences therein.
The IPS standards are therefore expected to be
sufficiently flexible so that the users can adapt
these standards to their requirements. However,
they may not cover every requirement of each
project. For such cases, an addendum to IPS
Standard shall be prepared by the user which
elaborates the particular requirements of the user.
This addendum together with the relevant IPS
shall form the job specification for the specific
project or work.
The IPS is reviewed and up-dated approximately
every five years. Each standards are subject to
amendment or withdrawal, if required, thus the
latest edition of IPS shall be applicable
The users of IPS are therefore requested to send
their views and comments, including any
addendum prepared for particular cases to the
following address. These comments and
recommendations will be reviewed by the relevant
technical committee and in case of approval will
be incorporated in the next revision of the
standard.

This standard covers the arc welding of butt,
fillet and socket welds in carbon and low alloy
steel for liquid and gas transmission pipelines
and related facilities including pig traps. The
welding may be carried out by a shielded metal
arc welding, submerged arc welding, gas
tungsten arc welding, gas metal arc welding or
flux cored are welding process or combination
of these processes using a manual, semiautomatic or automatic welding technique or
combination of these techniques. The welds
may be produced by position or roll welding or
by a combination of position and roll welding.
Roll welding is only acceptable when using a
fully automatic welding process.
Oxyacetylene welding (otherwise known as gas
welding) and flash butt welding processes shall
not be used.
The use of gas metal arc, gas tungsten arc and
flux cored arc welding (except the self-shielding
type) processes shall be restricted to
construction areas protected against wind and
draught.

testing, Welding Procedure Specifications shall
be submitted to the Company for review.
Welding procedures shall be tested to
demonstrate that acceptable welds can be made
by the procedure. The quality of the welds shall
be determined by both non-destructive and
destructive testing, as specified in (5.6). The
welding procedure qualification testing (WPQT)
shall be witnessed by the Company. Only
qualified and approved welding procedures shall
be used for production welding.
Unless otherwise stated in the contract
documents, for each contract all existing
welding procedures shall be requalified by the

may be designed to prevent such cracking from
occurring. The welding of these grades of pipe
may also require the use of low hydrogen

Preheating shall be carried out using either
electrical resistance or induction heaters or
using gas burners specifically made and shaped
for this type of operation. Torches intended for
flame cutting or gouging shall not be used.
Induction heating coils can cause arc blow
during welding, therefore power to these coils
shall be off when welding is in progress.
Where induction heating is proposed for the
application of either preheat or post-weld heat
treatment, the equipment and the procedure to
be used shall be approved by the Company. In
particular, the Contractor shall demonstrate to
the satisfaction of the Company that heating
rates and required temperatures can be properly
controlled and that adequate precautions have
been taken against overheating.

To maintain the low hydrogen content as
specified in (4.2.2.1), electrodes shall be baked
immediately before use at 300°C (± 30°C) for
one hour or in accordance with Manufacturers
recommendations. This requirement may be
waived when the electrodes are removed from
an hermetically sealed package immediately
before use. Plastic wrapped cartons are not
considered to be hermetically sealed.
After drying as described above, electrodes may
be transferred to an intermediate storage cabinet
maintained at approximately 150°C. Upon
removal from such drying or storage the
electrodes shall be transferred in small numbers
to heated quivers with a minimum temperature
of 70°C and used within 4 hours.
Electrodes not used within 4 hours, or for some
reason exposed to adverse atmospheric
conditions, shall be baked again in accordance
with the above conditions. Electrodes may be
baked twice only. If these electrodes are not
used within four hours after the second baking
treatment, they shall be discarded.

Radiation surveys are an integral part of the safe
operation of x-ray machines or radioactive
sources which must be conducted by contractor.
These surveys which are conducted to determine
the extent of radiation hazard in any given area
is vitally important when working in a
populated area. The survey meter is a rate
instrument which indicates the exposure
received per unit time. The most commonly
used instruments are the geiger muller counter
(G-M) and chamber meters. The effect of
distance on the intensity of radiation is
calculated by the inverse square law,
represented by the following equation.
I 1 ( D2 ) 2

:‫ﻛﻪ در آن‬
Where:
‫ = ﺷﺪت ﺗﺸﻌﺸﻊ‬I
