Metal hose with flange connection
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.

Metal hose with flange connection is used for transporting liquids and gases, including explosive and aggressive, almost all industries. All stainless steel metal hose for industrial use, with flange connection are manufactured according to GOST, ISO 9001:2000, TUV CE, DIN. Main criteria increase the service life of the metal hoses is professional installation and proper operation of the pipeline.
Metal hose with flange connection 4657А with a flexible part in type SRGS.
Sealed high pressure hose with flange connection 4657А and corrugated sheath type SRGS are used for transporting all kinds (including aggressive) environments, for joining pipelines, removing vibration loads.
In order to increase durability and protection from mechanical damage corrugated part of the high pressure hose has a protection metal braid mesh type. The braided metal hose for the unloading of extreme corrugations put on the glass, covering part of the corrugations from the thermal effects of welding or soldering, reducing the area of the sealing valve bending stresses. Welding of stainless flange to a flexible part of the hose is carried out using TIG welding. Flexible part of the sleeve is formed from profiled steel tape coiled in a spiral, thickness 0.15 — 0.4 mm, with a further seam contact welding of tops of the corrugation. Metal hose with flange connection 4657А with a flexible part in type SRGS manufactured with a diameter of 40 — 250 mm, 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.
