产品详细信息

The J55 API-5CT casing pipe is a comparatively low steel grade in oil drilling. It is widely applied for shallow oil and gas extraction.Because of its low cost among other grades of steel, it enjoys wider applications, can be generally used in shallow wells, geothermal wells, and water wells.
API-5CT K55 oilfield casing pipe is very similar to J55, there is no significant difference in the chemical composition and yield strength, however the ultimate tensile strength of K55 is higher than J55 steel, K55/J55 are 655MPa and 517MPa respectively.



K55 has better mechanical and thermal fatigue resistance and crack resistance than K55. For a thermal production well, the heavy wall K55 casing is appropriate instead of J55 casing. The former has a better thermal fatigue resistance property than the latter.
In present sales, the selling price of theses two types is generally kept the same, their application is very similar. In the oil drilling, K55 API 5CT casing or tubing is a relatively common type.
