Bellows bellows is directly connected to the two flanges together, it is a new connection fittings. The bellows is a corrugated outer faces of the thin-walled tubular member, typically made from stainless steel processing, having high axial elasticity. This product has displaced large amount of compensation, vibration isolation, high bearing capacity, low rigidity, long life and other advantages, and compensation structure type and have great flexibility. In the application of bellows expansion joints may be viewed as an elastic element. To release thermal expansion and contraction of the thermal stress on the device heat exchanger generally called expansion joints, expansion joints excellent large manufacturers in the pipeline, also known as bellows. Bellows expansion joints with a wide range of applications and installation in the heating pipe into the heating season bellows expansion joints in operation and operating state, the wholesale price of large-scale expansion joints, regular inspection and maintenance of the bellows expansion joints is particularly important. Check the time of bellows expansion joints should be once a month, so that both bellows expansion joints get a good inspection and maintenance, without affecting its operation, but the discovery of the accident as soon as possible. Check the contents of bellows expansion joints, what does: once a month to check corrugated portion bellows expansion joints and various parts of the weld has no leak is like, large expansion joints, and should be prepared in advance with several types of metal bellows expansion joints After the first time to prevent damage to replace up, so as not to delay the normal operation of the heating pipes.
