Metal hose with flange connection

Relevance

Metal hoses with flange connection are technologically no different from metal hoses for welding, except for the presence of the flanges themselves. They have a similar production method and manufacturing technology, as well as a similar bellows corrugated shell. The advantage of this type of connection is reliability, ease of installation, the possibility of repeated connection and disassembly.

Application

Metal hoses with flange connection are used for transportation of liquid and gaseous media, including explosive and aggressive ones, in almost all branches of industry. All stainless steel metal hoses for industrial purposes with flange connection are manufactured according to GOST, ISO 9001:2000, TUV CE, DIN. The main criteria for increasing the service life of metal hoses are professional installation and correct operation on the pipeline.

Metal hose with flange connection 4657A with flexible part of type SRGS.

Sealed high-pressure hoses with flange connection 4657A and corrugated casing of the SRGS type are used for transporting all kinds of (including aggressive) media, for joining pipelines, and removing vibration loads.

In order to increase strength and protect against mechanical damage, the corrugated part of the high-pressure hose has protection — a metal mesh braid. A cup is put on the braid of the metal hose to unload the extreme corrugations, covering part of the corrugations from the thermal effect of welding or soldering, reducing bending stresses in the reinforcement sealing zone. Welding of the flange to the flexible stainless steel part of the metal hose is carried out using argon-arc welding. The flexible part of the hose is formed from a steel profiled tape rolled in a spiral, 0.15 — 0.4 mm thick, with subsequent seam contact welding of the corrugation top. A metal hose with a flange connection 4657A with a flexible part of the SRGS type is produced with a diameter of 40 — 250 mm, the working pressure in the bellows part is up to 25 atmospheres, and the length is 250 — 6000 mm. The flange shape can be free or rigid, in accordance with GOST.
