Hardness test is required on all line items of every purchase order including pipes ordered for non-sour service.
Page sqmss of 28 Document Responsibility: Locations showing indications above the allowable limits may be reexamined by the manual ultrasonic method. The markings shall be paint stenciled using a medium and protective varnish that will provide a legible marking for at least one year of outside storage. Supervision of Level 1 personnel and interpretation of results shall be done by Level 2 employees. For each section containing cracks, a photograph shall be taken of the complete cross-section.
Inspection Specific Inspection [modification] The frequency of inspection for HIC test shall be one pipe from each of the first three heats supplied by each mill from each purchase order shall be tested and one pipe out of every five subsequent heats. The runoff for start and stop may extend up to one 1 inch sams either end onto the base metal. This annex is mandatory for all seamless pipes irrespective of service.
As an alternative, it is acceptable to carry out inspection for laminar imperfections on pipe adjacent to the weld seam in accordance with ISO with the acceptance criteria given in Table K.
sa,ss Page 22 of 28 Document Responsibility: Three samples shall be cut from one end, across the width of the plate. The cut shall be degrees from the spiral weld. Manufacturing procedure qualification as per Annex B is required for all pipes. Reference to Class I service has been discontinued because PSL 2 pipe ordered to this specification meets the requirements for Class I service by default.
Direct all requests to deviate from this specification in writing to the Company or Purchaser Representative, who samsss follow internal company procedure SAEP and forward such requests to the Manager, Consulting Services Department of Saudi Aramco, Dhahran. The hydrostatic test shall be conducted after all manufacturing processes including repairs and heat treatments are completed.

This class is for gas, two-phase flow, and liquid lines such as NGL, 0335 vapor pressure sass psia. For spiral-seam pipe, an 8 inches straight template parallel to the pipe axis may be used.
These books contain exercises and tutorials to improve your practical skills, at all levels! Verification shall be done at the pipe mill.
Unions are permitted only in the extended lines of in-line repairable valves top-entry ball valves and through conduit gate valves at a suitable location to facilitate removal of the bonnet.

This report shall include the mandatory requirements specified below: The orientation specified in Table 20 shall apply except that for spiral welded helical seam pipe, the specimen shall be transverse to the rolling direction of the skelp perpendicular to the helical seam.
Unless stated to the contrary in the Purchase Order, pipe manufactured to this specification must be suitable for internal and external coating with fusion bonded epoxy and other applicable coating materials.
The hydrostatic test shall be conducted after all manufacturing processes including repairs and heat treatments are completed.
Page 1 of 28 Document Responsibility: Seamless pipes shall not be delivered in the as-rolled R or Normalized rolled conditions; a separate heat treatment cycle shall be conducted using a designated heat treatment facility. Only electrodes identified on the repair welding procedure shall be used. If both of the retest groups pass, all pipes in the heat are acceptable except the one from which the initial test coupons were taken.
The specimen may be either flame cut or sawed from the parent pipe. It is applicable to pipe with wall thickness of 0. This testing is required to prevent blocking of the ultrasonic testing beam during weld inspection. The template must conform to a circle of the pipe’s nominal diameter and the length of the template must be one-fourth of the nominal diameter, except that it need not be over mm.
