OTAI Special steel supply the Seamless carbon steel pipe and the Alloy steel pipe. It is including the steel grade 1020, 1045, 4140,8620, Q345 and so on. Usually, the random length is ranged in 6-12meters.

The seamless carbon steel pipe has a hollow cross section, and is widely used as a pipeline for transporting fluids. For example used on the pipeline for transporting oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, this steel pipe has the same bending and torsional strength and light weight. It is an economical cross-section steel. It is widely used in manufacturing structural parts and mechanical parts. Like using on petroleum drill rods, automotive transmission shafts, Bicycle frames and steel scaffolding used in building construction.

Seamless carbon steel pipe is also an indispensable material for various conventional weapons. Gun barrels, barrels, and the like must be made of steel pipes. It can be divided into round tubes and special-shaped tubes according to the different cross-sectional area shapes. Since the circular area is the largest under the condition of equal perimeter, more fluid can be transported by the circular tube. In addition, when the cross section of the ring is subjected to internal or external radial pressure, the force is more uniform.
The use of steel pipes to manufacture annular parts can improve the utilization rate of materials. It can simplify the manufacturing process. It saves materials and processing hours, such as rolling bearing rings, jack sleeves, etc. And seamless carbon steel pipe have been widely used at present.

Otai exports various tool steel, alloy steel and carbon steel to more than 35countries from Europe and America, Middle East and Asia. Our steel materials meet DIN / ASTM / EN / JIS etc different international standards. We undertake every order to the end and solve customer’s problem without any hesitate on responsibility.
