OCTG Supplier
Oil country tubular goods (OCTG) is a type of seamless rolled product consisting of drill pipe, casing and tubing. Puwo provides a variety of OCTG as well as casing, tubing, drill pipe, oilfield pipe, drill collar, heavy weight drill pipe, slotted pipe, line pipe, coupling and pup joint, etc.
Casing pipe: Casing pipe lines the borehole. It is subject to axial tension by its dead weight, internal pressure by fluid purging, and external pressure by surrounding rock formations.
Tubing: Tubing is pipe through which the oil or gas is transported from the wellbore.
Drill pipe: Drill pipe is heavy seamless tube that rotates the drill bit and circulates drilling fluid.
According to the API 5 CT, pipe casing steel grade will be divided into H 40,J 55,K 55, C 75,N 80, L 80,C 90, T 95,P 110、Q125. PUWO specializes in oil pipeline,octg casing and piping such as API 5CT grade H-40,API 5CT Gr J-55,API 5CT grade K-55, API 5CT grade C-75,API 5CT grade N-80, API 5CT grade L-80,API 5CT grade C-90, API 5CT grade T-95,API 5CT grade P-110、API 5CT grade-Q125.we also can provide customers with products based on their specified technical requirements.

Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. It is made to withstand the pressure generated from the extraction process. Tubing is manufactured in the same way as casing, except that an additional process known as "upsetting" is applied to thicken the pipes.

Drill pipe is heavy seamless tube that rotates the drill bit and circulates drilling fluid. Pipe segments 30 ft (9m) long are coupled with tool joints. Drill pipe is simultaneously subjected to high torque by drilling, axial tension by its dead weight, and internal pressure by purging of drilling fluid. Additionally, alternating bending loads due to non-vertical or deflected drilling may be superimposed on these basic loading patterns.
