1. Short round buckle (STC)
Short round buckle is a common buckle type with the characteristics of convenient connection and good sealing.
2. Long round buckle (LTC)
The buckle length of the long round buckle is relatively long and is used in some occasions with certain requirements for connection strength and sealing.
3. Trapezoidal buckle (BTC)
The thread shape of the trapezoidal buckle is trapezoidal and has a certain deflection angle. It has good resistance to axial tension and compression and is suitable for complex working conditions such as deep wells and ultra-deep wells.
4. Special buckle
Special buckle is a buckle type designed to meet specific working conditions and use requirements, such as airtight buckle.
5. Thickened buckle (EUE)
The corresponding pipe clamp of the thickened tubing short section is the thickened buckle pipe clamp, which is suitable for situations where the strength of the connection part needs to be enhanced.
6. Non-thickened buckle (NUE)
The non-thickened tubing short section is equipped with a non-thickened buckle pipe clamp, which is used for tubing connection under general working conditions.
