Angular Hinged Expansion Joint
This angular hinged expansion joint consists of welded pipe, bellows, and a pair of hinges connected to the welded pipe. It can absorb the angular displacement of single plane only.It should be used when combined with two or three angular expansion joints during absorption displacement.The angular hinged expansion joint has the ability to withstand the thrust of internal pressure.
