Seamless steel pipe can be divided into two kinds, one is seamless circular pipe, the other is seamless square pipe, seamless circular pipe is the most important use of pipeline and mechanical industry, such as oil pipeline and natural gas pipeline, also natural gas pipeline; mechanical industry, automobile is made of semi-axle seamless steel pipe, as well as bicycle frame, can also be used as. Material for boiler production. Seamless pipe is mainly used in construction industry.


Seamless steel pipes need anti-rust paint before piping. Seamless square pipes are made first. Galvanizing and galvanizing are mainly divided into galvanizing and hot galvanizing. We usually see galvanized seamless square pipes are usually Hot-dipped Galvanizing because hot galvanized seamless steel pipes are much stronger than galvanized seamless steel pipes, because the main purpose of seamless square pipes is to Used in building steel structures, color steel houses, etc., will inevitably be eroded by wind and rain, and may rust and rot over a long period of time. So it is necessary to put a whole outside the protective film, but the paint looks too ugly and can not help exposing, so someone came up with a method of galvanizing. Sure enough, galvanized seamless square tubes have been greatly welcomed. Seamless square tube can also be used as the main frame of motorcycle and electric vehicle. It can also be used as a conduit for sending wires, etc. In recent years, China's oil pipeline industry and steel structure construction industry have developed very rapidly, which has also led to the development of seamless steel tubes. According to this development, we will become the largest seamless steel tube producer in the world.
