bends with a radius greater than three times the diameter (3D) are excluded from
the scope of this specification. Induction bends that have a radius 3D and larger
and are not under ASME B16.9 are not under by this standard. They are
addressed in 01-SAMSS-039.
1.3
This standard applies to fittings meeting the requirements of ASME B16.9 and
special designed fittings such as self-reinforced branch connections. Selfreinforced branch connection may be made from ASTM A105 or ASTM A350

Butt Welding Pipe Fittings
Where accessible, the weld metal hardness should be measured on the
I.D. surface of the fittings.
9.6
9.5.3.1
If any single indentation exceeds the allowable hardness limit,
two additional hardness indentations shall be taken within
25 mm of it, and the three hardness values shall be averaged.
If the average exceeds the allowable limit, the fitting shall be
rejected, and all the other fittings from the same heat shall be
100% hardness tested, even if not otherwise required in
paragraph 9.5.1.
9.5.3.2
The difference between the highest and lowest hardness
readings in the parent metal shall not exceed 20 HB.
In addition, for welded fittings, the difference between the
highest and lowest hardness readings in the weld metal shall
not exceed 20 HB. If the difference exceeds 20 HB for either
the parent metal or the weld metal hardness values, the fittings
shall be rejected, and all other fittings from the same heat shall
be 100% hardness tested, even if not otherwise required in
paragraph 9.5.1. For the purpose of determining the spread of
HB readings, a set of three indentations at the same location
may be substituted for any single reading and the average of
the three used instead of the single reading.
9.5.3.3
At the manufacturer's option, all fittings that have failed the
hardness test requirements in paragraphs 9.5.3.1 and/or 9.5.3.2
can be re-normalized and hardness tested again. Fittings that
pass the hardness test requirements and the strength
requirements after re-normalizing may be accepted. Fittings
that fail a second time shall be permanently rejected.
9.5.3.4
The hardness limit for ASTM A420 is 197 BHN.
Charpy Impact Testing
9.6.1
Charpy impact testing requirements for fittings in Grades WPHY-42 and
higher strength are given in MSS SP-75. Grade ASTM A234 Grade
WPB fittings do not require impact testing unless specified in the
Purchase Order.
9.6.2
For welded fittings, testing shall be performed on the base metal, heataffected zone, and the weld metal. The weld metal and heat-affected
zone impact test specimens shall be transverse to the weld axis.

Grade WPL 3 materials shall be tested as specified in ASTM A420.

10.4
After inspection by Saudi Aramco's Inspection Representative, unless otherwise
specified in the Purchase Order, fittings shall be supplied with a protective
coating that does not hide markings or surface defects. This temporary coating,
combined with appropriate packing, must protect against corrosion during ocean
shipment. The coating shall be hard and dry. It can be either a clear coating or a
thin opaque coating. Except for clear coatings, the maximum dry film thickness
shall be 76 micron. The fitting's normal stamped markings must be readable.
10.5
All fittings must be protected from mechanical damage. Welding ends must be
protected with suitable wood, plastic, rubber or metal covers. Fittings must be
packaged in steel-banded wooden crates or secured to skids.
Note:
If fittings up through 6-inch size are securely packaged in the wooden crates so
that they cannot shift during shipment and damage the welding bevels, the
separate covers are not required.
