DOUBLE WELDING ENDS
Description
A universal expansion joint is made up of two single bellows separated by a central pipe spool and its welding ends. The main aim of this construction is to achieve great absorption capacity of axial and lateral movements. This capacity depends on the bellows design and the intermediate spool length, the greater the length the greater the absorption capacity. Possible dilations on the intermediate spool are likewise absorbed by the two bellows.
This design cannot withstand pressure forces and must be supported by duly designed fixed anchorages.
Characteristics and Properties
- The most economical expansion joint
- Does not retain the force of the pressure
- Absorbs axial, lateral, and angular movements
- Must be properly anchored and guided.
Does not resist the force of the pressure, and must be supported by fixed anchoring that is properly designed. Otherwise, the joint may become overextended, with disastrous consequences.
