Surface treatment:

Coating choice of black or clear varnish exists for coating of the OCTG material.This coating is a solvent deposited non toxic phenolic PVB that provides atmospheric resistance to oxidation for a period of 6 to 12 months.

Test:

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.

Mill Test Certificate EN 10204/3.1B
