Construction

GNEE steel is one of the large manufacturers for high quality API 5CT K55 Tubes. API 5CT K55 casing pipe is very similar to J55 Casing Pipe.

GNEE's S355J2H precision seamless steel pipe is usually produced using a cold rolling process, which helps improve its precision and reduce losses during machining.

A pup joint is a casing or tubing of length shorter than Range 1 with the same thread connection, used to adjust the length of tubular strings to its exact requirement.

Boiler tubes is a one of seamless pipe. Manufacturing methods is the same as seamless tube, but it has the stringent requirements for manufacture of steel pipes.
