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.
