Description |
| Tie rods expansion joints |
 |
Tie rods expansion joints is mainly used in compensate for the axial movement, as well as able to compensate with the lateral movement or the combinations of axial and lateral movements.The screw rod of shipping bolt usually does not withstand the axial thrust. |
| The expansoin joints with external shrouds |
 |
This expansion joints are designed to compensate for axial movement that with external shrouds. |
| Flange connections expansion joints |
 |
The series are often compensate with axial movement, also used to compensate for lateral movement with flanges connections. |
| Axial expansion joints with thermal insulation |
 |
This expansion joints with heat insulation are to be able to absorb axial movement in piping system, which used on high temperature pipeline of steel mill, the petrochemical plant, the metallurgy plant. |
| Axial- bending resistance expansion joints |
 |
It is used to compensate for axial movement with the bending moment and self-guiding role. |
| Directly buried bellows expansion joints |
 |
It is mainly used for compensation to the displacement that can be directly buried in pipeline system with self-guided capability and maintenance-free life as well as fixed by the end stent. |
Double-seal directly buried bellows expansion joints |
 |
It is mainly used for compensation to the displacement that can be directly buried in pipeline system with self-guided capability and maintenance-free life as well as fixed in the middle of stent. |
| Dual axial expansion joint |
 |
The dual axial expansion joint has biggish axial movement that be used for larger axial displacement pipeline. |
