I Scope
This Specification covers amless and submerged-arc welded (SAW), straight-am
and spiral-am, steel line pipe manufactured in accordance with API Specification 5L (43rd Edition, 2004) to Product Specification Level 2. Unless stated in the purcha
order, all pipes shall be suitable for sour rvice.
Spiral-am SAW pipe shall be limited to nominal diameter size of 16 inches or larger.
Unless stated to the contrary in the Purcha Order, pipe manufactured to this
specification must be suitable for external coating with fusion bonded epoxy per
09-SAMSS-089. If the pipe will be internally coated 09-SAMSS-091 shall be followed, and this requirement shall be so stated in the Purcha Order. See paragraphs 4.2, 7.5
and 7.8.14.
II Conflicts and Deviations
A. Any conflicts between this specification and other applicable Saudi Aramco
Materials System Specifications (SAMSSs), Engineering Standards (SAESs),
Standard Drawings (SASDs), or industry standards, codes, and forms shall be
resolved in writing by the Company or Buyer Reprentative through the
Manager, Consulting Services Department of Saudi Aramco, Dhahran.
B. Direct all requests to deviate from this specification in writing to the Company or
Buyer Reprentative, who shall follow internal company procedure SAEP-302
and forward such requests to the Manager, Consulting Services Department of
Saudi Aramco, Dhahran.
III References
The manufacture and purcha of material covered by this specification shall comply
with the latest edition of the references listed below, as noted.

IV Modifications to API SPEC 5L
The following paragraph numbers refer to API SPEC 5L, which is the basis of this
specification. The text in each paragraph below is an addition or modifications to
API SPEC 5L, as noted. Paragraph numbers not appearing in API SPEC 5L are new
paragraphs to be inrted in numerical order.
1.2 Product Specification Level [modification]
All pipes shall be manufactured to PSL 2, with the additional requirements
contained in this specification.
[modification]
1.3 Grades
Pipe manufactured as Grade X60 or X65 (for sour and non-sour) may be
substituted for a lower grade if it meets all requirements for the lower grade
except maximum yield strength. API SPEC 5L Grade X70 may be
Next Planned Update: 17 January 2012 API Line Pipe substituted for a lower strength grade only for non-sour rvice. The pipe
shall be marked with the actual grade.
Commentary Note:
Maximum design metal temperature limitation established in ASME piping
code for X-grade pipe shall be noted when substituting the B-grade pipe.

广州肚皮舞培训学校4.2 Optional Requirements [addition]
Indicate in the Purcha Order only when required:
a) Suitable for internal coating; automatic welding required.
(See Scope, 7.2, 7.5, and 7.8.14)
b) Suitable for automatic welding (See 7.2)
c) Qualification for resistance to hydrogen-induced cracking
(See Appendix F)
d) Non-sour rvice (See 10.1.4)
5 Process of Manufacture and Material
5.1 Process of Manufacture [addition]
Welded pipe shall be made by the automatic submerged-arc process (fusion

welded) in accordance with API SPEC 5L, paragraphs 5.1.3.5 or 5.1.3.11
with a minimum of two welding pass on the outside and one on the inside.
(U of two or more wires is accepted as equal to two welding pass). For
wall thickness 7.9 mm and less, one outside welding pass may be acceptable
upon approval by the Buyer. Double am pipe is not acceptable for size
smaller than 60 inch nominal diameter. The steel shall be fully killed and
shall conform to the fine grain size requirement of ASTM A20.
5.1.1 Seamless Process [addition]
北京美国英语语言学院
Seamless Grade B pipe shall meet the requirements of ASTM A106 in
addition to the requirements of API SPEC 5L and this specification. The
primary compatibility item is the requirement for killed steel and 0.10%
minimum silicon content. For other properties, the more restrictive
specification applies in each ca.
Exception:
For pipe size 14 and larger, not for automatic welding, O.D. tolerances on the
pipe body and ends shall be in accordance with API SPEC 5L only.
Next Planned Update: 17 January 2012 API Line Pipe The manufacturing process and Inspection Tests Plan (ITP) shall be
submitted prior to the start of work to Saudi Aramco Vendor Inspection
Division/Quality Control Unit for approval.
5.1.2 Welding Process [addition]
The manufacturing Welding Procedure Specification (WPS) shall document,
as a minimum, all esntial variables listed in API SPEC 5L, Appendix C,
and tho listed below. A complete product test as required by API SPEC
5L shall verify that the WPS is acceptable. The actual material details and
welding parameters shall be documented in a Procedure Qualification
no one but you什么意思Record (PQR).
All testing shall be in compliance with this standard.
A Only electrodes and fluxes identified on the WPS shall be ud.
B All electrodes and fluxes shall be properly stored to prevent moisture
absorption, as recommended by the electrode and flux manufacturer.
C When making the skelp end weld for spiral welded pipe, runoff for
start and stop may extend up to one inch at either end onto the ba
metal.
D Repair welding procedures for the weld am shall meet the esntial
requirements and testing of API SPEC 5L, Appendix B & C, or ASME
SEC IX, at the option of the manufacturer. Only electrodes identified
on the repair welding procedure shall be ud.
E The welding procedures shall be available for review by Saudi Aramco
reprentative upon request.
F The manufacturer, trade name and type of weld wires and fluxes ud
for the PQR shall be specified on the WPS as esntial variables.
G The heat input specified on the WPS shall not be less than 90% of that
qualified by the production test and shall not exceed that qualified by
the production test.
H Recycling of crushed slag or contaminated flux is not permitted.
I Every batch of "G" consumable, if ud, will receive a product test.
J The manufacturing welding process is limited to submerged arc
welding (SAW).
