Flange connection metal hose with hinged bolts
Corrugated metal hose is sealed in the shell-type SRGS with flange connection with hinged bolts series 4656А designed for quick undocking-the joining of pipelines, transportation of various gaseous and liquid environments (including petroleum products). Flexible corrugated bellows of the sleeve has protection in the form of a multilayer metal mesh braid. Connections valves with bellows part, is mounted on the sleeve stainless steel Cup covering the end portion of the sleeve from the thermal effects of welding or soldering, reducing the area of the sealing valve bending stresses and producing unloading on the mesh braid extreme corrugations.

Quick couplings are welded to the corrugated stainless part of the metal hose with argon arc welding. Metal hose with flange connection technically does not differ from the weld metal conduit, except for the presence of the flanges themselves. They have a similar method of production and manufacturing techniques, and such bellows corrugated sheath. The advantage of this type of connection — reliability, ease of installation, the possibility of multiple connections and disassembly.
Flexible part of the sleeve is formed from profiled steel tape coiled in a spiral, whose thickness is from 0.15 — 0.4 mm, with a further suture the resistance welding the tops of the corrugation (SRGS). Metal hose with flange connection 4656А with a flexible part in type SRGS manufactured with a diameter of 50−150 mm, the working pressure in the bellows part is up to 25 atmospheres, and length 250 — 6000 mm. flange Shape is free and tight, in accordance with GOST.
Metal hose with flange connection is used for transporting different environments, including explosive and aggressive, almost all industries. All stainless steel metal hose for industrial use, with flange connection are manufactured in accordance with GOST, ISO 9001:2000, TUV CE, DIN.
The operating conditions in a sealed metal hose corrugated shell SRGS with flange connection and with hinged bolts series 4656А:
— Working environment temperature range -260°C to+ 800 °C;
— R (slave.) — operating pressure, depending on the vacuum: less than 280 kg/cm2;
— Working medium: air, steam, water, gases, corrosive media, oil products;
— Operating conditions of metal hose with flange connection depend on the material and type of flange.
