2. Rubber Expansion Joint has five types: single sphere rubber expansion joint, double sphere rubber expansion joint, threaded rubber expansion joint, reduced rubber expansion joint and rubber bending joint. Generally speaking, there are two kinds of connections: flange and threaded.
1. It is widely used in water supply and drainage, recycled water, air conditioning and heating, fire control, ship, water pump, and compressor, Etc.
2. They are low cost vibration and deflection absorption in fluid conveyance pipes.
3. The bellow consists of two symmetrical connecting end, either threaded unions for small nominal bores or flanged ends for large nominal bore pipelines.
4. They are ideal for compensating thermal expansion and contraction in piping system as an unbeatable cost effective alternative to expansion loops which require large amounts of materials and space.
The price is lower along with good quality and professional service. GYLDT provide better service and products. we are expecting to cooperate with you and would develop with you hand in hand.
