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.
