Longitudinal and spiral welded pipe is the main difference between the two different production processes, first of all, the formation of straight seam welded pipe is the first through the molding machine to form hot rolled coil, making it into a cylindrical cylindrical outer surface, and then Welding, welding using the proximity effect or under the flux layer of the arc and skin effect Differences between LSAW Steel Pipe and Spiral Welded PipeApr 20, 2017 · Spiral welded pipe is made by using low carbon construction steel strip or low alloy structural steel strip to roll into a tube according to a certain helix angle (called the forming angle), and then welding the seam together. It can use the narrow band steel to produce steel pipe with large diameter. Spiral welded pipe is mainly used for oil and natural gas pipeline, its specifications are
Manufacturing Process of ERW steel pipe Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond. Electric Resistance Welded - an overview ScienceDirect S.J. Yuan, G. Liu, in Comprehensive Materials Processing, 2014 3.04.6.3 Types and Standards of Tubes. Currently, seamless tubes, ERW tubes, drawn over mandrel (DOM) tubes, and laser-welded tubes are mainly used in IHPF. For steel tubes, the ERW tube has better formability and lower cost compared with DOM tubes and seamless tubes.
LSAW Steel Pipe Manufacturing Process:. LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated as LSAW) is a professional eion term for LSAW steel pipe.It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. Longitudinal Submerged Arc Welding (LSAW) Processes Longitudinally edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press subsequently into an O shape using an O-press. Figure 1:Longitudinal seam Submerged Welded (LSAW) pipes with UOE process
longitudinal seam welded carbon steel pipes suitable for line pipe, casing and tubing. In this process, hot rolled strip is gradually formed into round shape through roll-forming stands, and its edges are joined by a combination of localized high-frequency electric resistance heating and forge pressure, as schematically illustrated in Pre-treatment and use of straight seam steel pipeSep 11, 2020 · For the large-diameter steel pipe with the thickness of t=30mm for the pipe bridge, the longitudinal seam, and the circumferential seam are all-welded seams, which require 100% X-ray film inspection and 100% wave inspection; and for the thickness t= For the 24mm buried steel pipe, the longitudinal seam is a type of welding, and 20% X-ray film

The production of large-diameter longitudinal seam steel pipes in the industry will adopt T-welding technology, that is, to splice the short sections of the longitudinal seam steel pipe into a length that meets the engineering requirements, which greatly increases the probability of T-welding defects of the longitudinal seam steel pipe. Welded Stainless Steel Tubing Manufacturing Tour Plymouth Tubes facility in West Monroe, Louisiana, is committed to providing products and services that meet or exceed customers expectations. Rolled formed stainless steel tubing from strip steel is welded to produce as-welded tubes, as-welded bead conditioned tubes and tube rounds for cold drawing.
Jan 14, 2020 · Straight seam steel pipe refers to a welded steel pipe with only one weld in the longitudinal direction of the pipe body. GB / 9711.1 stipulates that when the diameter is greater than 914.4, the straight seam steel pipe can have two straight welds, What are the uses of straight seam welded steel pipe?Longitudinal welded pipe, the steel pipe made of hot-rolled or cold-rolled steel plate or steel strip by coil welding is longitudinally welded on the welding equipment, and the pipe obtained is called longitudinal welded pipe. (it is named because the welded joint of steel pipe is in a straight line). LSAW steel pipe and ERW steel pipe are two kinds of Longitudinal welded pipe.
