Short Description:

API 5CT J55 Oil casing:

J55 Oil casing is a steel pipe used to support the wall of oil and gas wells to ensure the normal operation of the entire oil well during the drilling process and after completion. Each well requires several layers of casing depending on different drilling depths and geological conditions. After the casing is run down, cement cementing is required. It is different from the tubing and drill pipe and cannot be reused.

API 5CT J55 Casing Tubing Specification:

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.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.
