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.
Steel Supply, L.P. offers Black ERW Pipe in many different sizes and wall thicknesses. ERW stands for Electric Resistance Welded, which is how the pipe is made. The Black ERW Pipe sold here comes in 21 foot lengths and can be shipped everywhere in the Continental US via LTL freight. The Pipe can also be custom cut to lengths of your choice.

ERW Standard Pipe. One of the Largest Size Ranges in the Industry. Wheatland Tubes ERW is available in all the common sizes, up to 18 NPS, and is suitable for welding, grooving, threading and bending. All wheatland black pipe is treated with our proprietary MIC Shield antimicrobial coating to prevent corrosion, for extended service life in all kinds of low-pressure and mechanical applications, as well as Electric Resistance Welded Pipe, ERW Steel Pipes, Electric Electric Resistance Welded Pipe. ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape are used in various engineering purposes. ERW steel pipe is formed by rolling plate and welding the seam.
Galvanized Iron Pipes are manufactured using mild steel strips of Low Carbon Steel Coils. The strips are passed through a series of fin rolls to give them a circular shape. The slit ends of the strips are then welded together by continuously passing high frequency electric current across the edges.
