The PHB range of small bore axial expansion joints are specifically designed to absorb the thermal expansion that occurs in straight Heating pipe lines.

​

They are fitted with Special Carbon steel or Stainless steel 2 hole flanges designed to absorb noise

and vibration that occurs in perimeter heating circuits.

​

As an alternative to our standard construction these Expansion Joints can also be custom made to specifically to suit your needs. This can be done by manufacturing them to specific lengths & movements especially to suit each application, be it replacement of existing expansion joints or brand-new systems.
