Steel Tube

Rectangular Steel Pipe can be divided into oval shaped steel tube, triangular shaped steel tube, hexagonal shaped steel tube, the diamond shaped steel tube, octagonal shaped steel tube, semicircle deformed steel circle, not equilateral hexagons five disc shaped steel tube, the plum flower form shaped steel tube, double convex shaped steel tube, double concave shaped steel tube, melon seeds shaped steel tube, the cone shaped steel tube, corrugated shape profiled steel pipe.

ASTM A106-C Carbon steel tubes have seamless and welded steel tubes, suitable for high temperature environments, common in boiler tubes, manufactured by cold rolled A106c steel pipe or hot rolled A106c steel pipe process, resulting in oxidation resistance and corrosion resistance.
Our company produces about 15,000 tons of steel per month and sells tens of thousands of tons of steel per month. We are able to make any order.

Galvanized rectangular pipe is a kind of hollow square cross-section steel pipe made of hot rolled or cold rolled galvanized strip or galvanized coil as blank by cold bending forming and then by high frequency welding of square section shape size; Or the cold-bent hollow steel tube made in advance and then hot dip galvanized galvanized rectangular tube. According to galvanizing processing technology, it can be divided into hot-dip galvanized rectangular tube, cold galvanized rectangular tube and electric galvanized rectangular tube.

ST42 Steel Tube is very important in industry and can be used as fluid transmission pipeline. ST42 Steel Tube is mainly used to produce mechanical parts with moderate bearing capacity and speed, and parts with high load, medium impact and speed. Combined with the actual needs, the seamless steel pipe processed by different processes has strong pertinence and practicability.

ASTM A135A Seamless Steel Pipe have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, ASTM A135A Seamless Steel Pipe has the same bending and torsion strength and lighter weight. It is a kind of economical cross-section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, Bicycle racks and steel scaffolding used in construction.

ASTM A106Gr.B Seamless steel tube is a kind of low carbon steel widely used in petroleum, chemical and boiler industries. The material has good mechanical properties. A106-b steel pipe is equivalent to China's 20 steel seamless steel pipe, in accordance with ASTM A106/A106M high temperature operation carbon steel seamless steel pipe standard, grade B. It can be seen from ASME B31.3 piping standards for chemical plants and petroleum refineries that the temperature range of A106 material is -28.9~565℃.

Square Steel Pipe is a kind of hollow square cross section light thin wall steel tube, also known as steel refrigeration bend section. It is made of hot rolled or cold rolled strip steel or coil plate as base material by cold bending forming and then by high frequency welding made of square section shape and size of steel. In addition to the thickening of the wall, the corner size and edge flatness of hot rolled extra-thick wall square tube reach or even exceed the level of resistance welding cold forming square tube. Good comprehensive mechanical properties, weldability, cold, hot working and corrosion resistance, with good low temperature toughness.

Galvanized pipe, also known as galvanized steel pipe, divided into hot dip galvanized and electric galvanized two, hot dip galvanized galvanized layer thick, with uniform coating, strong adhesion, long service life and other advantages. Electric galvanized cost is low, the surface is not very smooth, its own corrosion resistance is much worse than hot dip galvanized pipe.
