The threaded axial metal expansion joints are made of one single bellows element with internally or externally threaded end connections.
The threaded axial metal expansion joint does not restrain pressure thrust so adequate anchors and guides must be provided and they can be used only in piping systems that incorporate correctly designed anchors and pipe alignment guides.
Regardless of accessories, such as liners and covers, this model of welding ends metal expansion joints absorbs all of the movements in any one length of piping but it is mainly used to absorb axial movements.
The thread can be executed in two types
- MTE type of Expansion Joint is made up of one single bellows fitted with external BSP or NPT threads.
- MTI type of Expansion Joint is made up of one single bellows fitted with internal BSP or NPT threads.
