Further more knowledge about Black Steel Pipe
Generally speaking, black steel pipe can be considered non-galvanized steel pipe compared with galvanized one. During the production of the black steel pipe, there will be kind of black oxide substance forming on its surface, which is one reason that people are used to name it black steel pipe. However, the black oxide substance has no capacity of anticorrosion and antirust. In other words, it is necessary to take some measures to protect the black steel pipe from rusting in daily applications.
Black steel pipe’s tensile strength makes it a better choice for people to convey water and gas in rural and urban areas. Besides, the round steel pipe can also be used to protect electrical wiring and deliver high pressure steam and air. The oil and petroleum industries widely use black steel pipe for convey large quantities of oil through remote areas. Although it doesn’t have a corrosion resistant layer like the galvanized steel pipes or other welded steel pipes, its high fire resistant performance plays an important role in fire sprinkler system. In addition, its high heat resistant feature makes it possible to deliver hot water but not drinking water. In our daily life, we can often find the sewages made of the black steel pipe. However, there is no doubt that black steel pipe cannot be used to deliver drinking water.
The cold rolled steel pipe can be cut and threaded to fit various projects per as different requirements. Black steel pipe can be cut either with a heavy-duty tube cutter, cut-off saw or by a hacksaw. ERW black pipes are extensively used for gas distribution inside & outside of a house, hot water circulation in boiler systems, potable water, as well as drains waste or vent lines.
As for the modern techniques of black steel pipe, scientific advancement has greatly improved after the butt-weld method invented by Whitehouse. Today, with modern automatic machines, it has become possible for steel pipe manufactures to produce black steel pipes under the extremely high temperature and pressure. What’s more, it will somewhat facilitate steel pipe suppliers to satisfy different diameter requirements for customers.
In addition, with the development of modern manufacturing equipment and inventions in electronics, black steel pipe quality can be guaranteed strictly following various manufacturing standards. It is much likely that modern manufacturers will use special X-ray gauges to ensure uniformity in wall thickness of steel pipe in the coming days. However, it is still a long way to make a big difference in steel pipe industry in future.
