Seamless API 5CT Grade L80 Steel Oil Casing Pipe

Oil casing is used to support the oil, gas wells of steel pipe, in order to ensure the drilling process and the completion of the entire well after the normal operation. Each well has several layers of casing depending on the drilling depth and geology. Casing down to use cement cementing, it and the tubing, drill pipe is different, can not be reused, a one-time consumption of materials. Therefore, the casing of the total consumption of more than 70% of the wells. Casing according to the use can be divided into: catheter, surface casing, casing technology and oil casing.

  • Our engineers can provide you with the best solution for your industry-specific application requirements.

  • Our pipes can be sold all over the world with short lead times and excellent product quality.

  • Our sales team is on call 24 hours a day, we will contact you as soon as we receive your letter.
