longitudinal seam alignment - ASME (mechanical) Code

G'day,I have come across a problem in the field were a seam welded pipe has been welded end to end ( circumfrential weld) and the seams (longitudinal) are directly apposed to each other on either side of the cicrumfrential weld,I can not find in B31.3 where it states there must be a minimum amount these two longitudinal seams must be separated a certain amount,I have found the clause in AS What is the Joint Efficiency? - Arveng Training EngineeringJoint efficiency of welds can be defined as the reliability that can be obtained from the joints after welding.This coefficient can adopt values smaller than 1,and to some extent it can be said that the joint efficiency is a way of reducing the allowable stress of the material.What is the Difference Between Welded and Seamless Jan 06,2014 welded storage tanks Longitudinal welded joints in piping#0183;Because there is no longitudinal weld seam,seamless tubing is often considered to be a higher integrity product than welded sanitary tube.Case in point,there is no weld that could possibly leak.Also,with welded tubing,the heat affected zone of the weld seam is considered to be less corrosion resistant than the base metal of the tubing.

Types of Welding Joints - The 5 Different Types Of Welding

ASME B31.1 1998 127.3 Preparation for Welding (E) Socket Weld Assembly says In assembly of the joint before welding,the pipe or tube shall be inserted into the socket to the maximum depth and then withdrawn approximately 1/16 (1.6 mm) away from contact between the end of the pipeThe Welded vs.Bolted Debate Material Handling andWelded rack is more expensive to transport because it cubes out trucks before they are weighed out.Interlake distributor Jim Green says,You may only get 20,000 lbs.to 25,000 lbs.on a truck [loaded with welded rack] compared to 40,000 lbs to 45,000 lbs.on a truck loaded with knock-down rack.The Benefits of Bolted Tanks Vs.Welded Tanks ModutankApr 10,2017 welded storage tanks Longitudinal welded joints in piping#0183;Three Benefits of Bolted Tanks Vs Welded Tanks.Fast Assembly When you talk about the advantages of bolted tanks vs welded tanks and other types of popular tanks,one of the main perks is an easy assembly process.Concrete tanks have to be poured in place on-site,and with welded tanks,you have to wait for welding and inspection.
