Product introduction

The J55 API casing or tubing is a relatively common one in oil drilling. Because of the low
steel grade of J55, it is used for shallow oil and gas extraction. Due to its low price among
other grades of steel, it enjoys broader applications. The J55 API casing or tubing is widely
used in the extraction of natural gas and coalbed methane, and can be commonly found in
shallow wells, geothermal wells, and water wells.

J55 Tubing Material can be generally relevant to oil, development, shipbuilding, refining,
aeronautics, electric power, sustenance, paper, compound industry, restorative hardware,
boilers, heat exchangers, metallurgy, etc. 5CT J55 Casing Tubing serves to transport both
unrefined petroleum and gaseous petrol from oil and gas layer to the surface pipeline
subsequent to boring is finished. It can shoulder the weight created by the misuse procedure.
