API 5CT J55 カセージパイプ

API 5CT is a specification for casing and tubing for petroleum and natural gas industries-used for wells. This Standard specifies the technical delivery conditions for steel pipes (casing, tubing and pup joints), coupling stock, coupling material and accessory material and establishes requirements for three Product Specification Levels (PSL-1, PSL-2, PSL-3). Grade J55 Casing Tubing is an API 5CT oil ケーシングパイプ また、非反転端や外側反転端などの多様なエンド接続を備えた油井に使用されることが多いためです。

The API J55 casing and tubing have wide application used in the shallow wells, geothermal wells, and water wells in the natural gas and coalbed methane due to its lower price relatively. WLD steel is a leading API 5CT casing and tubing manufacturer and supplier, we provide not only a broad range of API 5CT J55 oilfield casing pipe and API 5CT J55 tubing but also casing coupling, perforated pipe and more.
