We also accept special coupling processing for customersupplied materials, including special coupling pipe couplings, special coupling oil casings, special coupling petroleum casings, special coupling oil pipes, and special coupling protective caps, all processed according to drawings and specifications.
Advantages of Special Couplings:
In the early use of oil well pipes, couplings were designed for different oil fields, blocks, and well conditions. However, with increasingly complex well conditions, there are higher requirements for the usage conditions of the pipelines. Various special couplings abroad have undergone testing, screening, and field practice, gradually forming over ten typical types of special couplings to meet the current needs of special oil fields. Although various special oil well materials can meet the needs of different well conditions, they share common advantages:
1. High Joint Strength: Can match or exceed the strength of the pipe body, suitable for deep and ultradeep wells.
2. Good Sealing Performance: Suitable for highpressure gas wells, oil wells, and thermal recovery wells.
3. Strong Resistance to Bending: Suitable for inclined wells, large displacement wells, and horizontal wells.
4. Easy to Connect and Tighten: Not easily disconnected, suitable for drilling operations in harsh environments such as deserts and oceans.
5. Good AntiSticking Performance: Can be loosened and retightened without damaging the threads.
6. Strong Resistance to OverTorque.
7. Good Corrosion Resistance.
