Maintain 50 mm (or) 4 times the pipe wall thick
which ever is less. 

for two welding joint distance

Dear Sir,

The distance between two weld joints should be 4 times the pipe wall thickness or one time the diameter of pipe but never closer than 1.5 inch. This is supposedly to prevent the overlap of HAZ of two joints.

Thanks and regards,
Pavankumar Reddy.

Not required any minimum distance between Socket weld joint as per ASME B31.3.

Referance : 

B31.3 Interpretations No. 14 Interpretation: 

Question (4): Does ASME B31.3-1993 Edition, Addenda b, have requirements for the minimum lengths of pipe sections between welds? 

Reply (4): No
