Q195 Q235 Carbon Seamless Pipe

Seamless Steel Pipe,as the name suggests,is a pipe without a seam or a weld-joint.
Seamless Steel Pipes is a tubular section or hollow cylinder,usually but not necessarily of circular cross-section,used mainly to convey substances which can flow-liquids and gases(fluids),slurries,powders,powders and masses of small solids.

◉ Product Details

Carbon Steel Seamless Pipes – it contains more carbon and iron in its composition. Depending on the grade, trace amounts of silicon, manganese, and copper are permitted in varying quantities. Therefore, the Carbon Steel Seamless Pipe material is stronger and is extremely resistant to stress. In heavy-duty facilities, these features make the pipes applicable.

Seamless pipe Including:Carbon Steel Pipe, Seamless Line Pipe, Boilers Tubes, Structural Steel Pipe, Precision Steel Pipe, Alloy Steel Pipe, Nickel Alloy Pipe

According to the production method, the seamless pipe is divided into a hot rolled pipe, a cold rolled pipe, a cold drawn pipe, an extruded pipe, a top pipe etc.

According to the shape of the section, the seamless steel pipe is divided into two types: a circular shape and an irregular shape, and the shaped pipe has a square shape, an elliptical shape and the like.

The maximum diameter is 650mm and the minimum diameter is 0.3mm.

Seamless steel pipe is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation.
