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.

OCTG main products include:casing,tubing,drill pipe,drill collar, heavy weight drill pipe,slotted pipe, coupling and pup joint.
(1)Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore.size:OD: 4 1/2’’ ~ 20’’ (114.3mm ~ 508mm)；WT: 0.205’’ ~ 0.635’’ (5.21mm ~ 16.13mm)；LENGTH: R1, R2, R3
