Hot Rolled Seamless Steel Tube, Hot rolling is relative to cold rolling, cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature.

Hot Rolled Seamless Steel Tube, Advantages

It can destroy the casting structure of steel ingot, refine the grain size of steel, and eliminate the defects of microstructure, so that the steel structure is compacted and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent. Bubbles, cracks and looseness formed during casting can also be welded under high temperature and pressure.

Classification

Hot Rolled Seamless Steel Tube, It is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipe.

Cold rolled (dial) seamless steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, also includes carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel pipe, special-shaped steel pipe. The outer diameter of hot rolled seamless pipe is generally greater than 32mm and the wall thickness is 2.5-75mm. The outer diameter of cold rolled seamless steel pipe can reach 6mm and the wall thickness can reach 0.25mm. The outer diameter of thin-walled pipe can reach 5mm and the wall thickness is less than 0.25mm.

General seamless steel pipe: it is made of 10, 20, 30, 35, 45 and other high-quality carbon bonded steel 16Mn, 5MnV and other low alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot rolled or cold rolled. 10, 20 and other low carbon steel manufacturing seamless pipe is mainly used for fluid pipeline. 45, 40Cr and other medium carbon steel made of seamless pipe to manufacture mechanical parts, such as cars, tractors stressed parts. The general use of seamless steel pipe to ensure the strength and flattening test. Hot rolled steel pipes are delivered in hot rolled or heat treated condition. Cold rolled delivery is heat – treated.

Allowable deviation of normalized outer diameter

D1 ±1.5%, minimum ± 0.75mm

D2 plus or minus 1.0%. Minimum + / – 0.50 mm

D3 + / – 0.75%. Minimum + / – 0.30 mm

D4 + / – 0.50%. Minimum + / – 0.10 mm

Steel tube weight calculation formula

[(outer diameter - wall thickness)* wall thickness]x0.02466=kg/ m (weight per meter)

Hot Rolled Seamless Steel Tuben, Functional Purposes
