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.
