The Steel Pipe

Steel pipe can be divided into two types according to their production methods: seamless steel pipe and welded steel pipe, and they have their own characteristics:

1,Seamless steel pipe is the internal wear into a hollow. It can be used in pipelines for liquid transportation, such as oil pipelines, gas pipelines etc. Its weight is light , tensile strength is 8 to 10 times than the ordinary steel, and it can be used to manufacture mechanical parts. It also has good corrosion resistance and shock resistance, good toughness, high temperature resistance.

2,Welded steel pipe by bending the steel plate into a roll, and made by welding, the efficiency of production is high. Its high strength, and has the high bearing capacity and compressive resistance, is widely used in construction, aerospace and other fields. At the same time, its plasticity and machinable type is also very good, and it is convenient for other to process and remould.
