Carbon steel pipe
Product Description
Carbon steel pipes are divided into hot rolled and cold rolled (drawn) steel pipes.
Hot rolled carbon steel pipe 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 pipes.
In addition to ordinary steel tubes, low and medium pressure boiler steel tubes, high pressure boiler steel tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, and other steel tubes, cold-rolled (pulled) carbon steel tubes also include carbon thin-walled steel tubes, alloy thin-walled steel tubes, stainless thin-walled steel tubes, and special-shaped steel tubes. 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 pipe can reach 6mm, the wall thickness can reach 0.25mm, and the outer diameter of thin-walled pipe can reach 5mm, and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.

Production Method
The steel pipes are divided into seamless steel pipes and welded steel pipes. The production process of seamless steel pipe is to thread solid tube blank or steel ingot into hollow capillary, and then roll it into steel pipe of required size. Different piercing and rolling methods are used to produce seamless steel tubes. The production process of welded steel pipe is to bend the tube blank (steel plate or strip) into a tube, and then weld the gap to become a steel pipe. Different forming and welding methods are used to produce welded steel pipes.
Package
Standard airworthy packaging, or customized according to customer needs.

Applications
There are many uses of steel pipes, which can be widely used in auto parts, geological exploration, bearings, machining, etc. Seamless steel pipes are mostly selected for general steel pipe selection. Compared with welded pipes, the performance is better and the surface quality can meet certain requirements.
