" LSAW steel pipe " is a straight seam submerged arc welded steel pipe. Its main process features are:1. In the process of steel pipe forming, the steel plate is uniformly deformed, the residual stress is small, and the surface is not scratched.
Difference between ERW Pipes, SSAW Pipes and LSAW Pipes Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double-sided submerged arc welding. The finished products have larger specifications and the welding joints have excellent ductility, plasticity and good sealing.
You will see the weld seam of the LSAW pipe and SSAW pipe is higher than the steel plate. And the tolerance of weld seam height is specified in specifications. If compare ERW pipes with SAW pipes, ERW pipes surface quality is better. ERW pipes are smooth and have a better finish.
ERW/LSAW Welded Steel Pipe - China SHANGH TOP STEELLong-distance oil and gas pipelines are connected by a large number of single steel pipes. 1b fedlitate the on-site butt joint construction, the steel pipe manufacturer needs to machine the designed welding groove and blunt edge on the pipe end of each steel pipe and ensure th
Introduction to Welded Pipe Manufacturing - The Process Jul 26, 2018 · The LSAW pipe diameter range is larger than ERW, normally from 16 inch (406mm) to 60 inch (1500mm). Good performances on high pressure resistance, and low-temperature corrosion resistance. Spiral Submerged Arc Welding (SSAW) Process. In Spiral Submerged Arc Welding (SSAW) Process, also known as HSAW pipe, welding line shape like a helix.
Ultrasonic LSAW Pipe Inspection Solutions Krautkrämer SNUP-LO Waygate Technologies Krautkrämer SNUP-LO system is designed for automated ultrasonic inspection of the weld seam and Heat Affected Zone (HAZ) on Linear Submerged Arc Welded (LSAW) pipes meeting the needs of API, DNV and other oil and gas transmission pipeline standards.
LSAW Pipes Manufacturers in India, CS & MS Longitudinal LSAW pipes are manufactured by submerged arc weld manufacturing process. Our Company specializes in production of longitudinally welded pipes, with maximum diameter of 2600mm, and 80mm wall thickness, while the length of single pipe could reach 12000mm.
LSAW Steel Pipe DefinitionLSAW steel pipe is a cylindrical shape in which a hot rolled coil is formed by a forming machine and deforms the coil into a smooth shape, and is welded by using a skin effect and a proximity effect of a high-frequency current or an arc burning under a layer of the solder. The edge is heated and melted, and it is fused under a certain squeezing force and finally cooled to form.

Longitudinal Submerged Arc Welded Pipe (LSAW) Market Key points from the Longitudinal Submerged Arc Welded Pipe (LSAW) market report:Impact of COVID-19 on the growth matrix. Statistical records pertaining to overall market size, revenue, and sales volume. Major trends in the industry. Growth opportunities and associated risks. Estimated values for the growth rate of the market and its segments.
Longitudinal Submerged Arc Welding (LSAW) Processes Longitudinal Submerged Arc Welding is a specific welding technique used in pipe production where the finished product requires a particularly high wall thickness due to high internal or external pressures.
The two main types of LSAW pipes are:Longitudinal (single or double straight seam weld, DSAW) and Spiral (SSAW, HSAW, or SAWL pipe). The difference between DSAW and LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, while LSAW pipes have a single seam weld on the outer surface, longitudinal or cross sectional.
