High Quality Oil&Gas Seamless Casing Steel Pipe API 5CT N80

API 5CT is a specification for casing and tubing for petroleum and natural gas industries-used for wells. This Standard specifies the technical delivery conditions for steel pipes (casing, tubing and pup joints), coupling stock, coupling material and accessory material and establishes requirements for three Product Specification Levels (PSL-1, PSL-2, PSL-3). Grade N80 is an API 5CT oil casing pipe and mostly utilized for oil well with varied end connections such as non-Upset ends or an external upset end.

There is two types for API 5CT N80 oilfield casing pipes: N80-1 and N80-Q types, which have the same chemical composition and mechanical attributes while just various in the heat treatment. N801 steel pipe is treated by normalizing and tempering and N80Q is treated by quenching and tempering. The collapsing strength and internal pressure strength of N80Q are higher than that of N801 correspondingly.
