Seamless round tube and seamless square tube

Seamless steel pipe can be divided into two types, one is seamless round tube, one is seamless square tube, seamless round tube is the most important use of the pipeline and machinery industry, such as oil pipelines and natural gas pipeline, also there are natural gas pipeline and so on; there is the machinery industry, the car is made of semi-axle is made of seamless steel, as well as bicycle steel frame, but also as a material for the production of the boiler. The seamless tube is mainly used for the construction industry.

Seamless steel pipe in the pipeline before the need to rust paint, and seamless square tube is made of first, galvanized, galvanized way is mainly divided into galvanized and hot galvanized in two ways, we usually see galvanized seamless square pipes are generally hot-dip galvanized because hot-dip galvanized seamless tubes are much stronger than galvanized seamless steel tubes because the main purpose of seamless square pipes is for construction steel structure, color steel room, etc., will inevitably be the erosion of wind and rain, a long time there may be rust off, rotten. So it is necessary to have a whole outside the protective film, but the paint looks too ugly, and could not help but exposure, so someone came up with a galvanized approach. Sure enough, galvanized seamless square tube has been a great welcome. There are seamless square tube also as a motorcycle big frame, electric car's main frame and so on. Also as a pipeline to send wires and so on. Seamless steel pipe style specifications are numerous, numerous, each have their own role in recent years, China's oil pipeline industry and steel structure construction industry is very rapid, but also led to the development of seamless steel pipe, according to this The development of the next we will become the world's largest production of seamless steel pipe in a country.
