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.

The JIS G3458 standard is formulated for heat-resistant alloy steel pipes used as high-temperature fluid conveying pipes for heaters and boiler tubes.

ASTM A106 steel pipe is a seamless carbon steel nominal wall pipe suitable for high temperature environments, which can meet the needs of various forming operations such as bending and flanging. Pipes with sizes of NPS 1-1/2 and below can be processed by hot working or cold drawing.
