Steel Casing Pipe API 5CT

Steel casing pipe is a type of pipe used in the oil and gas industry, primarily for well construction. It is designed to provide structural integrity and support to the wellbore, preventing collapse and protecting the surrounding environment from contamination.

Octal Steel provides a comprehensive selection of API 5CT steel casing and tubing pipes to meet various needs in oil exploration and production. The materials offered include carbon steel (the most commonly used), alloy steel, chrome steel, and high alloy steels. The API 5CT grades available encompass J55/K55, N80 Type 1, N80Q, L80, C90, T95, P110, and Q125, along with additional specifications for 13 Cr.

Steel Casing pipe Feature

Casing pipe section shape is a round, big diameter pipe put into the oil well, fixed by the cement, to protect other equipment which is mostly made of iron and steel. Oil wells shall be designed to bear the different strengths of external power, such as crush, explosion, stress, and chemical corruption. During the well drilling process, put casing into the well bore, it will stabilize the well bore perfectly.

Key Features of Steel Casing Pipe:

• Material: Typically made from high-strength steel, casing pipes are engineered to withstand high pressures and harsh conditions encountered during drilling operations.
• Standards: Steel casing pipes often conform to industry standards such as API 5CT, which specifies the requirements for casing and tubing used in the oil and gas industry.

Application

API 5CT casing pipe is used to support the oil and gas pipe wall and to ensure the drilling process and the post-completion wells’ normal operation. Each well depending on the depth of drilling and geological conditions, uses several layers of casing. After cementing casing to be used to go down, it is different from tubing, and drill pipe and can not be reused, a one-time consumable material. Therefore, the casing consumption accounts for over 70% of all the oil well pipe. According by usage can be divided into the sleeve pipe, surface casing, casing, and production casing.
