What is OCTG casing?

OCTG casing is large diameter pipe which needs to be cemented into the borehole. The diameters of OCTG casing pipe range from 4.5″ to 20″. The pipe is well-cemented and stands strong, it acts as the structural component of the well and offers hole integrity.

Test Method

Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield Strength, Elongation), Technical Properties (Flattening Test, Flaring Test, Bending Test, Hardness Test, Blow Test, Impact Test etc), Exterior Size Inspection, Nondestructive Test (Ultrasonic flaw detector, Eddy current flaw detector), Hydrostatic Test(The standard pressure is limited to 20, 7 MPa (3000psi)), Electro-magnetic inspection to SR1 is carried out on all line pipes.

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.

The main products of EASTSUN are API 5CT tubing casing pup joint coupling nipple crossover geological drill pipe and line pipe as well as their materials which with different kinds of steel grades and threads. Our annual sales reach to twenty million dollars.
