Dark colour steel that has not been coated with zinc or other paint substrate is usually referred to as a black steel pipe. The dark colour of the surface is due to the presence of iron oxide that develops during the manufacturing process.
Industrial Uses of Black Steel Pipe
These dark-coloured steel pipes are strong and durable, hence used for various commercial purposes. They provide toughened strength with little maintenance. Steel pipes help transport water and gas to villages, rural, and urban areas.
Other uses include:
Petroleum and oil industry units to lay mega pipes for oil and gas.
Gas distribution in residential areas, water wells, and sewage plants
Make conduits to safeguard electrical wiring.
How are galvanised steel pipes made?
Firstly, steel pipes are made using two distinct ways for welded or seamless steel pipes. In both these methods, raw steel is cast into a mould and then stretched into a fine seamless tube. For welded tubes, the edges are forced together and sealed. Every year, innumerable tons of steel pipes are manufactured. Steel pipes are always in high demand.
galvanised steel tubes are those steel pipes that get dipped in a preservative zinc coating to resist corrosion and rust. galvanised pipe was a very convenient and low-cost option to lead pipes used for water supply lines.
How are black steel pipes unique and different from galvanised steel pipes?
The uncoated black-coloured steel pipes are produced when steel pipes are forged to form a black oxide cover on their surface, which gives it a natural finish. Pipes that are not galvanised are also called MS black pipes or mild steel black pipes. MS pipes are converted into tubes or any kind of tubular product and are one of the most affordable metals available for industrial uses and can last for more than 100 years.
galvanised steel pipes have zinc metal covering on their surface. During the galvanising process, steel is put or immersed into molten zinc to form a strong and uniform coating. Galvanised steel is corrosion-free.
The appearance of a black steel tube is blackish and darker than galvanised pipes. The galvanised pipes are more silvery and greyish in appearance. The main purpose of black steel tubes or pipes is to carry and transport natural gas into residential as well as commercial properties. Likewise, the primary function of galvanised pipes is to carry and provide water to houses and commercial structures.
Black-coloured steel pipes cannot be used for carrying portable drinking water as they can corrode in the water and the minerals found in the pipes can enter the water and also clog the waterline.
Material and standard specifications for black steel pipes include size range, SCH type, grade, and diameter details. You can buy top-quality black Jindal steel pipe that are much cheaper when compared to galvanised pipes. Black pipes have no zinc coating and do not undergo lengthy manufacturing processes, which further reduces the price. Black pipes are more valued for their tough quality and minimum maintenance.
