Types
  • API 5CT Tubing/OCTG API Tubing
  • It is characterized by uniform wall thickness, high dimension precision, excellent mechanical property and good process performance. This API tubing is widely used in oil wells for extracting petroleum or natural gas.
  • API 5CT Casing
  • This type of steel pipe features good sealing performance, high connecting strength, excellent surface treatment process, optimized structure, rational design, and so forth. It is mainly applied for the casing wall of oil and gas wells. This casing pipe can also be used in oil wells for extracting petroleum or natural gas, similar with API tubing.
  • API 5CT Coupling Stock
  • It is typically applicable for manufacturing coupled pipes (Pipes that can do couplings.). This product is well known for high mechanical strength and good overall performance. The screw thread or thread is made by adopting dedicated CNC machining, and is of high manufacture precision, reliable performance and long usage life. Coupling adopts phosphating or copper plating treatment, resulting in good wear resistance and strong anti-adhesive thread. Besides, this coupling stock is also famous for high-quality inside and outside surface, high dimension precision, uniform thickness of pipe wall, and so on.
