Cold rolled (dial) carbon 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, oil cracking pipe, other steel pipe, also includes carbon
thin-wall steel pipe, alloy thin-wall 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 be up to 6mm,
and the wall thickness can be up to 0.25mm. The outer diameter of
thin-walled pipe can be up to 5mm, and the wall thickness is less than
0.25mm. General carbon steel pipe: is made of 10, 20, 30, 35, 45 and
other high-quality carbon junction 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 low carbon steel manufacturing
seamless pipe is mainly used for fluid conveying pipe. 45, 40Cr and
other medium carbon steel seamless pipe to manufacture mechanical parts,
such as cars, tractor parts. Generally use carbon steel pipe to ensure
the strength and flattening test. Delivery of hot-rolled steel pipes in
hot-rolled or heat-treated condition; Cold rolled and delivered in
heat-treated condition.
