Steel Casing pipe appearance

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.

API 5CT casing pipe 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.
