The use of metal hose

Metal bellows hose, there are two, one is the spiral bellows; another is an annular bellows. Bellows  Hydraulic tube fittings  corrugated bellows is a tubular housing arranged in two adjacent corrugation has a helix angle, all of the bellows are connected by a spiral. Bellows Bellows is a corrugated tube was closed annular shaped housing, between waves and wave ripples from the ring series. Bellows seamless pipe or welded pipe from the forming process. Constrained by the processing methods, compared with spiral corrugated pipe, its single-tube length is usually shorter. Bellows advantage of good elasticity, stiffness smaller.
