Flexible connection of pipelines, pumping units, other units operating under high pressure, up to 400 Bar, at temperatures from -270 ° C to + 600 ° C, is carried out by means of a special metal hose. The corrugated steel hose is a sealed device for the transfer of chemicals, oil products, and other substances. RNVD for welding from ZGS "Standard" correspond to European quality standards.
