Re: [MW:11800] FW: hydraulic test pressure of Pipe.

Hi, For Stainless stell pipes,(Ex.,SA312) please find below the Code Extraction od SA312. It is the option of the manufacturer unless otherwise purchaser specified to do Hydroatatic test.   12. Hydrostatic or Nondestructive Electric Test 12.1 Each pipe shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order. 12.2 The hydrostatic test shall be in accordance with SpecificationA 999/A 999M, unless specifically exempted under the provisions of 12.3. 12.3 For pipe whose dimensions equal or exceed NPS 10, the purchaser, with the agreement of the manufacturer, may waive the hydrostatic test requirement when in lieu of such test the purchaser performs a system test. Each length of pipe furnished without the completed manufacturer's hydrostatic test shall include with the mandatory markings the letters "NH." 12.4 Nondestructive Electric Test: Nondestructive electric tests shall be in accordance with Specification A 999/A 999M.   16. Certification 16.1 In addition to the information required by Specification A 999/A 999M, the certification shall state whether or not the material was hydrostatically tested. If the material was nondestructively tested, the certification shall so state and shall show which standard practice was followed and what reference discontinuities were used.   For Alloy Tubes (Ex.,SA213) Please find below the Code Extraction of SA213   10. Hydrostatic or Nondestructive Electric Test 10.1 Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.       Thanks & Regards,     (Karthik) Karthikeyan.S QA/QC Manager Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.

To: materials-welding@googlegroups.com Date: Monday, July 18, 2011, 11:45 AM Dear Experts Generally hydraulic test pressure of Carbon Steel pipes are defined by SA-53. But what about the Stainless Steel & Alloy Steel pipes ? Can anyone reply please.     Regards -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding+unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/ The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.
