ASTM A36 A53 1000mm LSAW SSAW Steel Pipe Large Diameter API5l 5CT Oil and Gas for Sch 40 Carbon Steel ERW Spiral Welded Pipe Tube

Welded steel pipe is created using a flat steel plate or steel strip, and its manufacturing process results in a seam on its body. Specifically, when a welded steel pipe is manufactured, a steel plate or strip is bent and subsequently welded into either a circular, traditional pipe shape or a square shape. LSAW pipe, SSAW pipe, and ERW pipe are all types of welded steel pipe that are categorized based on how they are welded. For instance, LSAW pipe is welded longitudinally, and SSAW pipe is spiral-welded. ERW pipe is electric resistance welded, which results in a seam that runs parallel along the pipe body.


No matter the type of welded steel pipe, production is quick and efficient and costs less than the production of alternatives like seamless steel pipe. Overall, welded steel pipe is an affordable, adaptable choice and can be used for a number of different purposes.
