RE: [MW:12421] Distance between two butt joints in pipe weld

Dear Sir(@MPK),

 

The copy’s you send mentions requirements for spacing between longitudinal welds, Mr. Pradip is asking for spacing between butt welds in pipe so in my opinion he’s talking about circumferential welds!

 

Met vriendelijke groeten / Best Regards

B31.3 is silent about that..so you need to refer back to project or client specification..some of client specify 2x or 50mm..
