Overview |
|---|
Metal Expansion Bellows are all metal construction, flexibilities come from the corrugated stainless steel hose. Metal Expansion Bellows are mainly used to offset pipe line thermal movements and vibration. They are widely applied in oil, marine, water supply, pumping system and chemical industrial.
Metal Expansion Bellows 5010 is the basic type of Metal Expansion Bellows, it is composed of one piece of corrugated hose and two pieces of flanges. Usually metal expansion bellows are completed with inner sleeve to protect the convolutions and tie rods to limit the movements.
