Product Description

Carbon steel is divided into carbon structural steel, carbon tool steel and free cutting structural steel. Carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel; According to the smelting method, it can be divided into open hearth steel and converter steel; According to deoxidation method, it can be divided into boiling steel (f), killed steel (z), semi killed steel (b) and special killed steel (TZ); (4) According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25% - 0.6%) and high carbon steel (WC > 0.6%).
 

Cold-rolled carbon steel pipes
Cold-rolled carbon steel pipes are divided into general steel pipes, low/high pressure boiler steel pipes, alloy steel pipes,stainless steel pipes, petroleum cracking pipes, etc., as well as carbon thin-walled steel pipes, alloy thin-walled steel
pipes, etc. Outside diameter of cold-rolled seamless steel pipes It can reach 6mm, and the wall thickness can reach 0.25mm. Cold
rolling has higher dimensional accuracy than hot rolling.
 

Hot-rolled carbon steel pipes
Hot-rolled carbon steel pipes are divided into general steel pipes, low- and medium-pressure boiler steel pipes, high-pressure
boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.

Advantages of carbon steel pipe:

(1) Steel pipes of different diameters can be produced using strip steel of the same width, and
steel pipes of large diameter can be produced from narrow strip steel.
(2) Under the same pressure conditions, the stress of the spiral welded seam is smaller than that of the straight seam, which is
75% to 90% of that of the straight seam welded pipe, so it can withstand greater pressure. Compared with the straight seam welded pipe of the same outer diameter, the wall thickness can be reduced by 10% to 25% under the same pressure.
(3) The size is accurate, the general diameter tolerance does not exceed 0.12%, the deflection is less than 1/2000, and the
ovality is less than 1%. Generally, the sizing and straightening process can be omitted.
(4) Continuous production is possible. In theory, long steel pipes can be produced, with small head and tail loss, and can
increase the metal utilization rate by 6% to 8%.
(5) The equipment is light in weight and low initial investment. It can be made into a trailer-type mobile unit to directly
produce welded pipes at the construction site where the pipeline is laid.

Carbon steel  is widely used from the general engineering structure to cars, Bridges, ships, boilers and pressure vessels and other manufacturing, have been used in large quantities.
