The manufacturer, trade name and type of weld wires and fluxes used for the PQR shall be specified on the WPS as essential variables.
Anezi, Mohammed Ali on Copyright? The cut shall be degrees from the spiral weld. Storage and handling practice must ensure that there are no mechanical dents on the pipe surface. The above requirements pertaining to impact testing are in line with paragraph 4. Actuators All actuators shall be purchased from a source approved by Saudi Aramco. Removal of outside weld reinforcement from the pipe ends is needed to facilitate the movement of the automatic ultrasonic probe as part of pipeline field automatic welding requirement.
Pipe that is to be joined using pipeline field automatic welding systems Pipe that is designated in the Purchase Order as “Suitable for Automatic Welding” shall meet the following additional requirements: Locations showing indications above the allowable limits may be reexamined ssmss the manual ultrasonic method. Purity of the utilized salts and H2S for the test solution. Cold expansion of 0.
Out-of-Roundness at the ends shall not exceed 1. Page 17 of 28 Document Responsibility: The carbon equivalent shall not exceed the maximum limits tabulated below, unless approved by the Chairman of the Saudi Aramco Materials and Corrosion Control Standards Committee. If this examination is done before the hydrostatic test, the Purchaser’s Inspector may, at his sole discretion, require re-examinations by manual ultrasonic method of any questionable areas after the hydrostatic test.
Gear operators for quarter turn valves shall be equipped with a self-locking system.
Only Vickers hardness testers shall be used. For pipe size 14 and larger, not for automatic welding, O.
Pipe intended for subsequent internal coating shall have a maximum length of Steel that passes the HIC test, but has not been intentionally manufactured to be HIC resistant steel shall 0035 be used.
The Vendor shall provide an experience list including the names of specific persons to contact with their telephone and facsimile numbers. Cold expansion of 0. Isolated, definitely identifiable cracks shorter than 0.
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. All weld repairs must be carried out before heat treatment and hydrotest. Hardness test is required on all line items of every purchase order including pipes ordered for non-sour service.
Pipe furnished from Vendor inventory may be accepted with the standard API test pressure by negotiation. However, two additional joints of pipe or pieces of plate may be selected at random from the same heat for further testing. If no defects are located during re-examination, the original findings may be ignored.
Pipe lengths less than 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. For thicknesses in excess of 1.

All rejected pipes shall be identified and segregated separately from acceptable pipes in accordance with ISO – Ultrasonic inspection shall be over a width samsa 25 mm. Repair welding procedures for the weld seam shall meet the essential requirements and testing of Annex Samxs. Disposition of pipe containing defects [modification]: Acceptance criteria for base metal, weld metal and Heat Affected Zone shall be 34 J minimum for the average of three specimens and 27 J minimum for individual values based on full size specimen.
