Outer Diameter 114.3mm - 610mm ( 4 " - 24 " ) Q235 ERW Black Steel Pipe
ERW black steel pipes have a variety of use thanks to their strength and needs for little maintenance. They tend to be used for transporting gas and water to rural areas and urban areas or for conduits that protect electrical wiring and deliver high pressure steam and air. In addition, erw black steel pipes are also used in oil and petroleum industries for piping large quantities of oil through remote areas.
Other uses of erw black steel pipes include gas distribution inside and outside homes, water wells and sewage systems. However,erw black steel pipes are never used for transporting potable water due to the fact that they tend to corrode in water and mineral of the pipe will dissolve into the water and clog the line as well.
Steel is produced when carbon is added to iron, which is quite weak on its own. In modern industry, carbon is the most prominent additive to a ferrous material, but alloying elements of all sorts are common. In fact, alloying elements are common even in piping products still considered to be carbon steel.
Black pipes are formed from low – carbon mild steel on Automatic tube mill by high-frequency induction welding process. ERW pipes are welded longitudinally, manufactured from coil and can be manufactured up to 24” Diameter.
Black Steel Pipes have wide use across many industries due to its strength and ease of workability. Because it contains relatively few alloying elements and in low concentrations, black steel pipe is relatively economical.
