Steel pipes can be used to transport fluids and powdered solids, exchange heat, and make mechanical parts and containers. It is also an economical type of steel. The steel pipe is used to make the frame, strut and mechanical support of the building structure, which can reduce the weight and save the metal, and realize the factory mechanization construction. Making a highway bridge with steel pipes not only can save steel, simplify construction, but also can greatly reduce the area of coating protection, saving investment and maintenance costs.
Tianchuang has different types of industrial steel pipes for sale, we can supply different types of steel pipes for different applications.
Tianchuang pipes use the following technologies: Hot-dip galvanizing(The molten metal reacts with the iron matrix to form the alloy layer); Galvanizing(Steel interacts with zinc to form a zinc-ferroalloy on the surface of the pipe).
ERW means electric resistance welding, and it is a resistance welding by 10-500 kHz of high-frequency current.
Material: The raw material of the ERW pipe is a hot rolled steel coil which is made of steel billet, and the usual material is Q195, Q215, Q235, Q355 in China steel grade, which are the same material with S195, S235, S355 in Europe, and SS400 in Japan.
The steel coil firstly will be cut into strip, the strip width is according to the perimeter of the pipe, and then shaped by mold, welding, cutting, straightening, inspecting, end smoothing, packing, and final storage or dispatch.
Application: The pipes are used widely in construction and infrastructure, such as scaffolding, water and gas delivery, fire control system, oil and heat delivery, and other low-pressure liquid delivery.
The normal length is 6m, and it also can be a flexible length decided by buyers.
We can produce ERW pipe according to GB/T3091-2015, JIS/G3444, EN10255, ASTM A500, ASTM A795, BS1387, EN39 and other standards. The pipe end can be a plain end, treaded with sockets, grooving end according to the above standards.
