Flexible Metal Hoses & Assemblies
Metal Hose Assemblies & Flexible Metal Hose Solutions
At Flexmetallic, we make flexible metal hoses and metal hose assemblies for tough industrial use. These stainless steel hoses are used where pressure, temperature or vibration make standard hose or rigid pipe unsafe.
Flexible metal hoses let pipework move without leaks. They absorb vibration. They also take up thermal expansion and small alignment changes between fixed points.
Our metal hose assemblies are British made at our Northampton facility. Every assembly is fully traceable and built to your specification. We supply power generation, chemical and petrochemical plants, HVAC systems, water treatment sites and cryogenic services.
Our Metal Hose Range
We make a range of flexible metal hoses to suit different pressure, temperature, and application needs:
- 7010 Unbraided metallic hose — general purpose and low pressure duties
- 7011 Single braided metallic hose — medium pressure with added mechanical protection
- 7012 Double braided metallic hose — higher pressure duties
- 7127 Interlocked / Stripwound hose — exhaust, ventilation, and non-pressure work
- 7701 Stainless steel overbraid — outer protection for hose or pipework
We also supply duplex and jacketed hose assemblies, dog leg assemblies, and metallic expansion joints. For high pressure applications up to 300 bar, see our high pressure metal hose range.
Custom Engineered Metal Hose Assemblies
Each flexible metal hose assembly is built to your requirements. You can specify bore size from ¼" to 6" internal diameter, length, pressure rating, temperature range, and connection type. End fittings are available in flanged, threaded, or welded types, with materials matched to your process and environment.
Outer covers, interlock casings, and fire sleeves can be added where extra protection is needed. Full 3.1B material certification and permanent etching for traceability are available on request. Learn more about our bespoke assemblies.
Assemblies can be designed and tested to ISO 10380 for corrugated metal hose assemblies. View our certifications.
Construction & Materials
Hoses are made from stainless steel grades 304, 316 and 321. Specialist alloys are available for more severe duties. These materials give a good mix of corrosion resistance, strength and flexibility. Hoses handle temperatures from -200°C to +600°C and pressures up to 300 bar in the high pressure range.
Industry Applications
Flexible metal hoses and metallic hose assemblies are used across a wide range of plant and building services, including:
- Steam and condensate lines
- Chemical and petrochemical transfer
- Cryogenic and liquefied gas work
- HVAC and building services
- Water and fluid transfer systems
- Process and manufacturing lines
In these uses, the hose takes up movement and cuts vibration. It also handles changing temperature and pressure. This helps protect pumps, valves and other linked kit. See all applications.
Installation, Maintenance & Support
Good installation is key to hose life. Keep within the bend radius in the data. Avoid twist. Line up the ends so the hose bends where it should. Use anchors and guides so movement happens in the hose, not in the fixed pipe.
Checks in service should look for wear, kinks, sharp bends and damage at the fittings. This matters most in high movement or high vibration areas. When you find a problem, our team can advise on a new hose or changes to routing and support.
