A335-P22 Alloy Steel Pipe
A335-P22 Alloy Steel Pipe : A335-P22 Alloy Steel Pipe Production of steel pipe is generally grouped into two categories: Welded and Seamless. There are many methods of producing steel pipe in current use, however, most of the pipe produced is made either by the seamless, electric resistance weld (ERW) or spiral weld methods Continuous weld and double submerged arc weld are other common methods of manufacture. As a professional steel manufacturer, we produce thousands of tons of ASTM A335-P22 alloy tubes every month, and export a large number of high-quality products.
