FAV Stainless Steel Flexible Braided Corrugated Hose Assemblies
FAV Stainless Steel Braided Corrugated Hose Assemblies are engineered for demanding fluid transfer applications involving extreme temperatures, high working pressures, full vacuum conditions, continuous mechanical vibration, and corrosive chemicals where rubber or composite hoses degrade. Manufactured with an annular close-pitch hydroformed corrugated core in AISI 316L or AISI 321 stainless steel and reinforced with one or two layers of high-tensile AISI 304 or 316 braided outer wire sheath, these flexible metal hose assemblies absorb piping misalignment, thermal expansion, and compressor vibration while delivering leak-free containment from cryogenic temperatures (-200°C / -328°F) up to +600°C (+1112°F).
Core Tube: Close-pitch annular corrugated hydroformed seamless or TIG-welded tube in Stainless Steel AISI 316L / 321
Braided Reinforcement: Single or Double layer high-tensile wire braid in Stainless Steel AISI 304 / 316
Nominal Diameter Range: 1/4" (DN 6) up to 12" (DN 300) in custom factory-welded overall lengths (OAL)
Working Pressure Capability: Full vacuum up to 350 bar (5000+ PSIG) depending on diameter, pitch, and braid layers

Piping Alignment & Movement Notes
Never subject corrugated metal hose to torsional twisting during installation. Use two wrenches when tightening threaded end unions.
Maintain the recommended minimum dynamic bend radius to ensure unlimited fatigue cycle life under pump pulsation.
Industrial Applications & Performance
FAV Flexible Stainless Steel Corrugated Metal Hoses provide the ultimate safeguard against fluid release in critical industrial processes. Unlike polymer or rubber hoses that suffer from age hardening, chemical permeation, and catastrophic rupture under fire conditions, stainless steel metallic hoses remain 100% diffusion-tight and fire-safe.
Commonly deployed in pump suction and discharge lines, steam headers, chemical unloading stations, turbine exhaust manifolds, cryogenics (liquid nitrogen, LNG, liquid oxygen), and heat thermal oil loops, they absorb pump vibration cycles and thermal piping movement effortlessly.
100% fire-safe metallic construction prevents media release during plant emergency fire conditions
Zero gas permeation — essential for toxic gases, flammable hydrocarbons, and high-purity refrigeration media
High flexibility with small dynamic bend radius allows easy routing in congested skid machinery compartments
Custom protective armor accessories available: External Stainless Steel Interlock Guard, Silicone Fire Sleeve, or Spring Wire Guards
Custom End Connection Options
Fixed Male Pipe (NPT / BSPT)Hex nipple or pipe nipple welded directly to hose collar for rigid manifold connection
Female Swivel Union (NPT / BSPP / JIC)Allows quick alignment without twisting or applying torsion stress to the corrugated hose core
ASME Flanged Ends (RF / FF / Lap Joint)Class 150, 300, and 600 forged flanges in Fixed Weld Neck or Floating Lap Joint (Van Stone) styles
Sanitary & Quick CouplingsTri-Clamp sanitary ferrules (DIN 32676 / ISO 2852) for food/pharma and Camlock quick-disconnect fittings
