This bellow expansion joint consists of two working flexible metal hoses on both ends, a balancing hose in the middle, rods and end plate, etc. The effective working surface of the balancing hose is as two times large as that of working hoses. So the axial pushing force caused by internal pressure of the working hose can be offset by the opposite pushing force generated from internal pressure of the balancing hose. This expansion could only compensate axial misalignment.
As a professional manufacturer, we can offer all kinds of the metal pipe fittings
and can manufacture them according to any drawings .

1.Reasonable structure, good elasticity,large range of compensation pipeline and little counterforce to the brackets of pipeline.
2.Shock absorption and noise decrease,heat and dust insulaton,environmental protection and simple structure bracket.
3.The displacement can be deflected to prevent damagement caused by subsidence of connected brackets and equipment base.It can adapt itself to the centrifugal difference of pipeline installation to provede convenience to installation and maintenance.
4.Good resistance to milling,heat,aging and corrosiveness and long service life.
5.Little resistance and little weight.Each performance is better than the compensation device of other materials.
6.The temperature rage of media is wide:-40--300oC
1.Heating and air conditioning installation
