longitudinal seam alignment - ASME (mechanical) Code longitudinal welded pipe

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 longitudinal welded pipelongitudinal seam alignment - ASME (mechanical) Code longitudinal welded pipeRE: longitudinal seam alignment. 26 Jun 13 04:52. It is basically just good practice and as you say in company specifications normally to reduce the possibility of a seam weld failure turngin into a running fracture going into the next pipe.ASME B31.3 - Longitudinal Seam weld - Pipelines, Piping longitudinal welded pipeThe manufacturer (from India) produces the pipe with 2 plates, resulting in 2 longitudinal seam. Their argument was, nowhere is A358 it mention two seam cannot be used, obviously a flawed argument. I am trying to counter with B31.3 or A358, just dont know the right clause to

ASME B31.3 Quality Factors - Little P.Eng

Jul 10, 2017 · The quality factor for API 5L spiral weld pipe is 0.95; the welds are 100% UT examined per the specification. The quality factors for castings are described in para. 302.2.3 of the Code. Due to the conservative stress basis, the casting quality factor for gray and malleable iron is 1.0.Difference between helical welded pipes and longitudinal longitudinal welded pipeAs for longitudinal welded pipes, to meet the required length of pipelines used in industry projects, short longitudinal pipes always need to be jointed and welded into a long enough pipe. Thus, inevitably, many T-shaped welding seams would appear in this welding process, largely increasing the possibility of welding defects.Introduction to Welded Pipe Manufacturing - The Process In Longitudinal Submerged Arc Welding (LSAW) Process, longitudinal edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press and subsequently into an O shape using an O-press.

If a longitudinal seam fails, the fracture most likely stops at the closest girth weld down stream from the start point. This helps limit the damage that would result, if a longitudinal weld fails, to a smaller area.Mukat Pipes - LONGITUDINAL SAW PIPESMukat Pipes Limited situated on Rajpura Patiala Road, Rajpura -140401  (Punjab) on NH-7  was established in 1987 with the Modern Technology  to manufacture Large Diameter Submerged Arc Welded (SAW) M.S.Pipes both Longitudinal & Spiral process in the Diameter range of 12 inches to 100 inches and wall thickness upto 20 mm conforming to IS-3589-2001 by using high quality filler wire Automelt GR.

STRESS GUIDELINES AND PIPING DESIGN BASIS: WELD

Material specification used in the pipe line was ASTM A312 i.e Austentic stainless steel welded pipe. The scenario is longitudinal welds are made without the addition of filler metal using electric resistance welding(ERW) from both sides of the pipe wall. This process results in lack of fusion flaws in the pipe.Seam Joint Efficiency Factors for Factory Pipeline Bendsto apply to pipe containing longitudinal seams. This concern extends to wrought longitudinal welded pipe to listings for electric-fusion-welded pipe and electric-resistance-welded pipe in the Table 6 Allowable S Values for Pipe in Gas and Air Piping System stated: longitudinal welded pipe Seam Joint Efficiency Factors for Factory Pipeline Seamless or welded pipes? - BUTTINGlongitudinally welded pipes must therefore be performed to a high-quality level and must take account of the specific parameters. Conclusion The decision whether to use a seamless or welded pipe depends principally on the wall thickness / diameter ratio and the specified pipe tolerances. Normally the advantages of the welded pipe outweigh the alternative,

Types of Oil & Gas Pipes: Seamless, ERW, LSAW longitudinal welded pipe

The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.Welded Longitudinal Finned Tubes | Vulcan Finned TubesWelded Longitudinal Finned Tubes.
