Materials & Welding

Pressure test is a mandatory requirement of  pressure piping designed and fabricated according to B-31.1 code. Clause 137 & various other clauses  of this code explicitly specifies the requirements. The medium could be Hydro or Pneumatic .   Pneumatic test is  not advisable for safety and integrity of piping components. Hence Hydro test is the default choice.   Hope it clarifies your doubt.   Thanks.     P.Goswami.P.Eng, IWE.

Dears, I have an bug on EN 15614-1 regarding to pipe description.There is no description of pipe. When I machine below flange from plate, is it designated as pipe or not? When I have an joint as below,My body material thickness is 50mm.  My customer requested pipe wpqr for this joint. But I think I can cover this joint with an 30mm Butt Weld WPQR.

Generally,  piping drawings shall take care of this type of issues during fabrication of pipe spools.  It is a very common problem, if you don't have any option to move the support,  then before the support cut and add one pup piece pipe and do all welding and NDT as per the  regulations  and avoid the fouling.  Regards Anil  On Mar 28, 2017 8:51 PM, "'Biplab Pal' via Materials & Welding" < materials-welding@googlegroups.com > wrote: Dear experts, We need your kind support based on your experience and any code/std references.

Dear Anil, You change the orientation or rotate the LSAW pipe (main pipe) if possible. Otherwise get clarification or approval from your design engineering. Once approved you can do Welding. Please note that after welding of branch pipe (with or without RF Pad), additional radiography of 150 mm (both sides) shall be taken on main pipe long seam weld to ensure the weld metal soundness. The above radiography requirement is  more enough to satisfy the Client.
