What is the Longitudinal Seam and Transverse Joint in

SMACNA refers to the Longitudinal as a seam and Transverse as a joint.A seam is securing together two longitudinal oriented edges of duct in the direction of airflow.A joint is the Transverse connection that connects the end of one duct section to another.The Longitudinal Seam in Rectangular Duct is either a Pittsburgh Lock or a Snap Lock.What is seam welding? Westermans BlogB.Longitudinal Seam welding.The advantage of using a seam welder is that it easily enables the joining of two flat plates of a tubular pipe without any tack welding.Longitudinal seamers provide an automated welding process carried out on smooth plates,sheets,pipes and tank sections to make cylindrical work pieces.What is a LSAW steel pipe? ASTM A234 butt weld pipe LSAW pipe (longitudinal Submerged Arc Welding Pipe) is fromed by JCOE with one straight welded seam,the outer diameters usually from 323mm to 1420mm.When the outer diameter is 914.4mm above,its allowed two straight welded seams.LSAW pipe is used to convey low pressure liquid meida or high pressure petroleum or natural gas,and can be

Welded vs.seamless steel pipe American Piping Products

Weld seams produced from low-frequency ERW were more prone to corrosion and seam failure.Most welded pipe types require heat treatment after manufacture.Manufacturing seamless pipe.Seamless piping begins as a solid cylindrical hunk of steel called a billet.While still hot,billets are pierced through the center with a mandrel.Types of Oil Gas Pipes Seamless,ERW,LSAW 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.Tube Bending Where to Locate the Weld Seam - TheSep 08,2011 Longitudinal weld seam on piping#0183;Bending,Tube Bending Except for seamless tubing and pipe,the other grades of tubing and pipe have a longitudinal weld seam.When tube bending is done for OEM parts,the question often arises about where to locate the weld seam.

Straight vs.Spiral Seams Perforated Tubes,Inc.

Straight-weld pipes are created by bending and forming metal,which is then welded together down the length of the pipe to create a straight,longitudinal seam.Spiral-weld pipes,on the other hand,are rolled and welded according to a preferred helical angle.Steel Casing Pipe Straight Seam,Spiral Welded, Rolled Straight Seam Steel Casing Pipe Straight seam steel casing pipe is so called because the pipe is rolled from strip and formed with one longitudinal weld .This straight seam steel casing pipe is generally manufactured by an Electric Weld or a DSAW type of manufacture.Selective Seam Weld Corrosion How Big is the Problem Selective seam weld corrosion (SSWC) is a type of corrosion that affects the bondline region and heat affected zone (HAZ) of the longitudinal seam of a pipeline forming grooves in the seam.The term selective refers to the preferential attack of the weld zone rather than the adjacent base metal.
