Precision carbon steel seamless steel pipe: appearance: bright, smooth and flawless; production process: finishing rolling; tolerance size: +0.05 mm-+0.1 mm purpose: mechanical processing of hydraulic cylinder parts, etc.
Carbon steel pipes can be divided into hot-rolled and cold-rolled (drawn) steel pipes.
Hot rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler pipes, high pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
Cold rolled (dialed) carbon steel pipes include general steel pipes, low and medium pressure boiler pipes, high pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes and other steel pipes. They also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes and special-shaped steel pipes. The outer diameter of hot-rolled seamless pipe is generally larger than 32 mm, the wall thickness is 2.5-75 mm, the outer diameter of cold-rolled seamless pipe can reach 6 mm, the wall thickness can reach 0.25 mm, the outer diameter of thin-walled pipe can reach 5 mm, the wall thickness is less than 0.25 mm, and the dimension precision of cold-rolled seamless pipe is higher than that of hot-rolled pipe.
General carbon steel pipe: It is hot rolled or cold rolled with high quality carbon-bonded steel 16Mn, 5MnV or low alloy structural steel 40Cr, 30CrMnSi, 45Mn2, 40MnB etc. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transmission pipelines. Seamless tubes made of medium carbon steel, such as 45, 40Cr, are used to manufacture mechanical parts, such as stress parts of automobiles and tractors. In general, the strength and flattening test of carbon steel pipe should be guaranteed. Hot-rolled steel pipes are delivered in hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in heat-treated state.

The best mode of transportation:
Shipping steel by sea, land and air is a heavy cargo product. Generally, it is better to ship steel by sea than by air. Samples should be shipped by air more quickly and conveniently.
Precision carbon steel seamless steel pipe: appearance: bright, smooth and flawless; production process: finishing rolling; tolerance size: +0.05 mm-+0.1 mm purpose: mechanical processing of hydraulic cylinder parts, etc.
Hot-rolled seamless steel pipe: rough appearance, tolerance: +0.2mm-0.5mm; generally used for fluid conveying, mechanical manufacturing, structural welding, etc.
Isocooled Seamless Steel Pipe: Its production process is cold-drawn and its appearance is slightly worse than that of precision pipe; Tolerance: +0.15-+0.25 mm; On the basis of hot rolling, it can save materials; On the basis of economy, it is cheaper than precision pipe; Usage: Hardware parts processing auto parts cylinder manufacturing ship manufacturing .
