Expansion joints

Self guided axial expansion joints (AS)

Experience has shown that there is a need for special type of unit for use by the heating and ventilating trade.As can be seen from the above diagram these units have an internal sleeve and an external shroud which makes it impossible to install them into pipework which is initially misaligned. In addition to begin practical the shroud also gives the Self Guided Axial a pleasing streamlined appearance. The units are supplied at their extended length and held at this length by a small set screw.

This ensures that they are at all times installed at their correct length which in turn ensures a life-time of trouble free operation. The internal sleeve gives a smooth flow of the water through the unit and the direction of flow is clearly indicated on the outer shroud. They can be supplied with end prepared for welding into pipework. Having installed the unit into the pipeline it only remains for the set screw to be removed.
