Metal hose is for hose materials of main parts are made by austenitic stainless steel, so as to ensure the good temperature resistance and corrosion resistance of the hose, hose used by the pipeline medium grade choose suitable stainless steel corrosion, so that it can ensure the corrosion resistance of metal hose. Widely used in mechanical, chemical, petroleum, metallurgy, food and other industries. Due to the wide use of metal hose, and also to the more attention to the service life of the, so what are the causes of damage of metal hose?

1, outside the wire net pulled off, can't afford to pressure, made the early end to the service life of metal hose. Due to internal corrugated pipe ends, take over and outside whole welded wire mesh need to trinity split, to ensure the normal use of metal hose. If the welder whole welding is a little careless, will appear the trinity welding is unqualified, once the installation work, will be pulled off, making the network can't shock absorption. In order to avoid this like now, before the products leave the factory, they must to be air tight water pressure test, qualified rear can leave the factory.

2, internal corrugated pipe crack open welding conditions, as this will also make metal hose is damaged. Sloppy this is due to the welding technology and the most prone to damage like now, because the seam welding is not strong, do not close, the hose working pressure, flow medium will burst weld makes metal hose leak appeared like now.

Above all, metal hose also appear easily damaged in the process of transportation and installation, so start dragon bellows remind everybody, must play well in advance in the process of transport packaging, the installation process, do not use welding slag splash into the corrugated pipe or steel wire net surface. Everyone in the installation and use have what not understand place to welcome you all to start the technical personnel of the dragon.
