Double Hinged expansion joints are made of by two single hinged expansion joints joined between them by a common connector and relative articulations
They resist to the thrust pressure and they are able to accommodate greater amounts of lateral movements in one plane only generating low forces on the anchoring.
They can also be made with bellows in stainless steel or special alloys depending of the use as 316 Ti, AISI 310, HASTELLOY, INCONEL, AVESTA 904L, MONEL 400, INCOLOY, etc.. and with ends in materials such as CORTEN, A335 P11, A333 Gr.6 and others upon request.
