Product Description

ERW Welded Carbon Black Structure Transportation Steel Pipe Tube
Black steel is the uncoated steel. When steel pipe is forged, a black oxide scale forms on its surface to give it the finish which is seen on this type of pipe. Because black steel is subject to rust and corrosion, the factory also coats it with protective oil. Those black steel are used for manufacturing pipe and tube, which will not rust for a long time and requires very little maintenance.

Usages:

Water, gas, air and steam, black steel tubes and pipes are utilized for gas distribution inside and outside the house and for hot water circulation in boiler systems. It is also used for line pipes in oil and petroleum industries, for water wells and for water, gas and sewage purposes. It is not used for potable water or for drain waste or vent lines.
