Re: [MW:0] Separation of joint

Dear Ahmed,

 

As per Saudi Aramco Engineering standard SAES-W-012, Welding Requirements for Pipelines

10.5   The minimum distance (circumferential offset) between longitudinal welds (including spiral weld seams) of adjacent Pipe joints     shall be 100 mm, except as noted below:

a) Longitudinal welds in fittings are exempt.

b) Pipelines classified as Class I service (see SAES-L-131) are exempt.

c) For all other applications, a situation involving seam alignment less than this is acceptable provided the next five girth weld joints on both sides of the affected joint meet the separation requirement.

 

Regards

 

Sajeev

Dear All,

 

During fit-up of two spools of SS304, It was observed that logitudinal seams of pipe are coming face to face, means there is no separation between long seams of large dia pipe. Is there any criteria stated in asme B31.3  or Aramco standard in this regard.

 

Regards,

 

Ahmed H.
