3. Process: ERW and Seamless

4. Size Outer Diameter: Casing OD 4 1/2"- 20" (114.3mm-508mm) Tubing OD 2 3/8" - 4 1/2" (60.3mm-114.30mm) Wall Thickness: 0.205"- 0.635" 0.205"- 0.635" Length: R1(4.88mtr-7.62mtr), R2(7.62mtr-10.36mtr), R3(10.36mtr or longer)

5. Connection: Casing LTC, STC, BTC, VAM. Tubing NUE, EUE

6. End: Beveled, Square cut. And pipe protection cap specially for casing and tubing.

7. Surface: Corrosion proofing water based paint

8. Coating: A 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.

9. Marking: Identification marking is applied to every pipe by means of paint stencilling along the length of the pipe and is in full accordance with Appendix D of API 5CT. Colour band marking is applied in accordance with said specification. Additional information pertaining to the bundle is printed on a weatherproof plastic label that is attached to the bundle.

10. 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.
