Flexible Metal Hose Assemblies
Athulya’s flexible metal hose assemblies combine annular corrugated stainless-steel hose with single or double SS wire braid to provide pressure-tight flexibility, vibration isolation, and thermal movement accommodation in compact spaces. Assemblies are custom-engineered with end connections to suit your service and site conditions, manufactured in line with EJMA/ASME practices.
Key Features
• Annular corrugations for high flexibility and pressure capability.
• Single / Double braid options to match pressure and pulsation requirements.
• Excellent for vibration absorption, pump/compressor connections, and misalignment.
• Wide media compatibility with stainless-steel wetted parts; leak-tight construction.
• End connections: flanged, weld ends, threaded (BSP/NPT), Camlock/quick-couplings as required.
• Optional external armor, spring guards, fire sleeves and bend restrictors for protection.
Applications
• Pump/compressor suction & discharge, turbine tie-ins, skid packages.
• Steam, condensate, hot oil, air/gas lines; cryogenic to high-temperature services.
• Refineries, petrochemicals, chemicals, power, steel & cement utilities and process lines.
• Where space is limited and vibration/thermal movement must be managed safely.
