We are leading manufacturer and stockist of API 5CT N80?CASING PIPES in China.API 5CT N80?CASING PIPES (N80-1,Website:http://www.petrosteels.com, N80-Q) Both N80-1 and N80-Q have the same yield strength and tensile strength, but N80-Q, which is quenched and tempered, shows a higher resistance to internal pressure and collapsing. On the other hand, casing N80-1 is cheaper to produce and the first choice were a higher collapse resistance in not needed. API 5CT N80?CASING PIPES Yield strength: 552-758 MPa (55-80 ksi), API 5CT N80?CASING PIPES?Minimum tensile strength: 689 MPa (100 ksi) API 5CT N80?CASING PIPES?API?color code: 1 red (N80-1), 1 red band + 1 bright green band (N80-Q)API 5CT N80?CASING PIPES?SIZES OD 4-1/2& quot; -- 20& quot; LENGTH R1, R2 ,R3API 5CT N80?TUBING SIZES OD 2-7/8& quot; -- 4-1/2& quot; LENGTH R1, R2OD 外径
