Application

Stourflex axial expansion joints are designed to accommodate pipe movements in an axial plane (straight runs) due to thermal expansion. They are suitable for L.T.H.W, M.T.H.W, steam and other hot liquids and gases.

The white aluminium external protective sleeve makes the Type JP113 particularly suitable for use where pipework is visible inside occupied buildings.

  • Maximum working pressure 10 bar at 200ºC.
  • Stourflex axial expansion joints should not be used at both their maximum working temperature and pressure respectively.
