Metal Hose with Flanges

Engineered for High-Integrity,Bolted Connections

A Metal Hose with Flanges is a specialized flexible conduit assembly designed for secure,leak-tight integration into flanged piping systems.This configuration combines the dynamic flexibility and durability of a corrugated metal hose with the robust,standardized connection method of flanges,making it ideal for demanding industrial applications requiring reliable,maintenance-friendly connections.

Core Construction&Design

Corrugated Metal Hose Core:The flexible element,typically constructed from stainless steel(304,316L,321)or high-performance alloys(Inconel®,Monel®).Available in annular(for pressure/vibration)or helical(for large movement)corrugation types.

Braiding:Reinforced with single or double layers of stainless steel wire braid to contain pressure,resist external damage,and dampen vibration.Unbraided versions are used for full vacuum or pure thermal movement applications.

Integral Flanged End Fittings:The defining feature.Heavy-duty,forged or machined metal flanges are permanently attached to each end of the hose assembly via:

Welding:Providing the strongest,most leak-proof connection,suitable for high-pressure,high-temperature,and critical service.

Swaging(Captive):A robust mechanical attachment method where the flange is crimped onto the hose and braid.

Flange Specifications&Standards

Flanges are manufactured to match common international piping standards,ensuring direct bolt-up compatibility:

ANSI/ASME B16.5:Standard for raised face(RF)or flat face(FF)flanges in classes 150,300,600,etc.

DIN/EN:Standards such as DIN 2633/2638(PN series)with raised face or grooved profiles.

JIS:Japanese Industrial Standards.

Flange Types:Common styles include weld neck,slip-on,threaded,and blind flanges.Weld neck flanges are preferred for severe service due to their structural strength.
