Pacific Hoseflex Metallic Expansion Joints (Bellows)
The thermal movement required can be axial, lateral or angular. In some cases, the pressure thrust of a pipe expansion joint must be restrained by the use of tie rods, hinges or gimbal while allowing the bellows to move through its design deflections.
Pacific Hoseflex Rubber Expansion Joints
Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:
- Absorb movement
- Improved thermal stability
- Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
- Reduce mechanical noise
- Compensate for misalignment
- Eliminate electrolysis between dissimilar metals
Pacific Hoseflex Teflon Expansion Joints
Pacific Hoseflex expansions joints are made of contour moulded PTFE (white or black), providing exceptional corrosion resistance and flex-life. The flexible liner is moulded over the metallic sealing face which eliminates troublesome separate gaskets and reduces the chances of bacteria build up. Different numbers of convolutions accommodate varying degrees of misalignment, axial travel and angular deflection between components. They are corrosion proof and non-aging.
Pacific Hoseflex Seismic Expansion Joints
Piping used in applications and locations subject to seismic conditions have their own set of unexpected random movements. The random motion common to earthquakes requires that seismic expansion joints to be capable of movement in any direction.
Pacific Hoseflex Expansion Joints are manufactured in accordance to the following standards:
- ISO 9001:2008
- Lloyd's approval
- All welding conducted is done to AS 4041 – Class 1
