Metal hose joint is a kind of high quality flexible pipe in modern industrial pipeline. It is mainly composed of bellows, net sleeves and joints. Its inner tube is a spiral or annular thin wall stainless steel bellows, bellows outer net set, is made of stainless steel wire or steel belt according to certain parameters woven.

Metal hose joint is a kind of high quality flexible pipe in modern industrial pipeline. It is mainly composed of bellows, net sleeves and joints. Its inner tube is a spiral or annular thin wall stainless steel bellows, bellows outer net set, is made of stainless steel wire or steel belt according to certain parameters woven. The joints or flanges at both ends of the hose shall match the joints or flanges of the customer's piping. The bellows of the hose are formed from extremely thin - walled seamless or multi-welded stainless steel tubes by high precision plastic processing. Because of the elastic characteristics of the bellows profile, the hose has good flexibility and fatigue resistance, so that it is easy to absorb the cyclic load of various movement deformation, especially in the pipeline system has the ability to compensate large displacement. Medium visualization, process automation.

During installation, both ends of the metal hose are relatively twisted. Mainly appear on both ends of metal hose, for the flange connection at the scene of the installation on board, often due to installation error, cannot be connected at both ends of the flange holes alignment, and offset, and thought the hose connector to withstand torsional displacement compensation, but in fact, metal hose itself can't compensate the torsional displacement, the result is a metal hose is broken, There is a leak in the pipeline. In this case, one end of a loose flange can be used to connect the metal hose.

Large radial deviations exist at both ends of the metal hose during installation. Although the metal hose can compensate lateral displacement, but if make it ends when the installation is relatively larger radial displacement, will reduce the direction of the actual amount can be compensated, may cause use need to the amount of compensation is greater than the hose in the direction of actual amount can be compensated in this direction, thus result in fatigue damage and damage of metal hose.
