Seamless black steel pipe

Seamless black steel pipe is made of seamless steel pipe that has not been galvanized. Its name comes from the scaly, dark-colored iron oxide coating on its surface. It's used in applications that don't require galvanized steel.

Material of seamless black steel pipe:
Seamless black steel pipe is made of ordinary carbon steel, low alloy structural steel or alloy steel. Among them, the C content of ordinary carbon steel is generally below 0.25%, the alloy content of low alloy structural steel does not exceed 5%, and alloy steel contains more alloy elements. After processing, these steels are directly cold drawn into seamless steel pipes without any dissolution heat treatment. The materials of seamless black steel pipe mostly is astm a53.

Features:

1. Seamless black steel pipes have high strength, toughness and good machinability, and can withstand high pressure and temperature, so they are widely used in petroleum, chemical, aviation, nuclear power and other fields.
2. There is no oxide layer on the surface of seamless black steel pipes, which has beautiful appearance, easy to clean and maintain, and has good corrosion resistance.
3. Seamless black steel pipes have good sealing performance and are not easy to leak. They are widely used in construction, machinery, automobile manufacturing and other fields.
4. Compared with welded pipes, seamless black steel pipes have advantages in service life, reliability, pipeline performance and other aspects.

Application of seamless black steel pipe:

The purpose of seamless black steel pipe is to carry propane or natural gas into residential homes and commercial buildings. So that pipes is manufactured without a seam, making it a better pipe to carry gas. Seamless black steel pipe's strength makes it ideal for transporting water and gas in rural and urban areas and for conduits that protect electrical wiring and for delivering high pressure steam and air. The oil and petroleum industries use black steel pipe for moving large quantities of oil through remote areas. This is beneficial, since black steel pipe requires very little maintenance. Other uses for black steel pipes include gas distribution inside and outside homes, water wells and sewage systems. Black steel pipes are never used for transporting potable water.
