A separate line of buisness of NPO GKMP is the production of high pressure metal hoses designed for flexible connection of piping systems, to reduce installation, thermal, vibration and other types of stresses arising in rigid pipelines. These bellows provide transportation of gaseous products and liquids of various chemical composition at temperatures from -270 to + 600 ° C, at pressures from vacuum to 44.0 MPa.
A complete manufacturing cycle has been organized starting from forming a tube from a strip, manufacturing a bellows, and implementing a protective one-, two-, or three-layer braid. This advantage, and, at the same time, having experienced production staff, allows us to guarantee the high quality and operational characteristics of the manufactured metal bellows and hoses, reduce the time and cost of manufacturing, and also sell products for special customer requirements.
The bellows is a flexible metal line element inside of the metal hose, which is responsible for flexibility and is certainly checked for leaks during the production process.
Braid is the outer part of a high-pressure metal hose, which consists of strands of stainless steel wire, depending on the diameter, from 0.3 mm thick.
Stainless steel wire braid is made on special modern braiding machines. The braid performs not only a protective role, protecting the internal flexible bellows of the sleeve from mechanical stress and harmful environmental factors.
The braid of a high-pressure metal hose is an important component that directly affects the technical characteristics of the finished product, primarily the ability to withstand the necessary parameters of the working pressure: with insufficient strength characteristics of a metal hose equipped with a single braid (one layer of wire strands), is applied a second or even third layer.
