Black steel pipe is not really a specification but rather a generic term used primarily by plumbers to distinguish regular steel pipe from galvanized steel pipe. Black steel pipes are cast from several grades of ductile or malleable iron, whereas carbon steel pipes are generally welded or seamless. Black Carbon Welded Steel PipeE, Square & Rectangular Black Carbon Welded Steel Pipe, Square & Retangular Tube means Electric Resistance Welded Pipes and the raw material is carbon steel, mainly character is the welding beam is smooth, two end no burr, hardness is very strong, so some special material can be use for machine components.

Difference Between Seamless And Erw PipeAll Carbon steel pipe such as Casing pipe and Tubing pipe made to API specifications uses seamless or electric-weld supplying processes. There are many Differences between Seamless & ERW Pipe. The main Difference is that the Seamless Piping is suppliers by hot-working steel or, if necessary, by subsequently cold-finishing the hot-worked product Difference between ERW, DOM and Seamless Tube Metal

As industrial applications have evolved and grown more complex, the piping products and systems that serve them have had to keep pace. While many pipe manufacturing methods exist, the most prominent discussion in the industry compares electric resistance welded (ERW) vs. seamless (SMLS) steel pipe.Carbon Steel Welded Pipe Low Carbon EFW / ERW Black Blackening is a process to generate a pertinacious oxide layer that implements some form of corrosion resistance. Essentially, erw black carbon steel pipe is not galvanized and is used in those applications that do not require the product to undergo galvanization. Although black steel pipes may be used to ferry across different substrates across rural and urban areas, it is not used to convey potable water for
