Metal Hose
Metal Hose is an industrial flexible hose solution for applications where conventional hose materials may not satisfy the required operating conditions. Corrugated metal construction provides flexibility for suitable piping arrangements, while stainless steel braiding supports the hose assembly under demanding service conditions.
Metal hoses are considered for industrial systems that experience high or low temperatures, vibration, movement or deviations between connected piping sections. Allarakhu & Sons lists Metal Hose under its Special Hoses category for industrial buyers and businesses seeking flexible metal hose assemblies.
Product Overview
The supplied manufacturer reference describes corrugated, acid-resistant metal hoses with stainless steel external braiding. It also describes stainless steel bellows hose assemblies that can be cut and welded with different thread and flange configurations.
The dedicated manufacturer information identifies AISI 316L stainless steel for the inner hose and AISI 304 stainless steel for the external braid. It also refers to manufacture and approval according to ISO 10380.
Metal hose assemblies can be selected to accommodate piping movement, absorb vibration and suit operating environments where temperature or chemical resistance requirements make conventional hoses unsuitable. The exact assembly must be selected according to the conveyed medium, operating pressure, temperature and connection arrangement.

Corrugated Metal Hose Construction
A corrugated metal hose uses a formed metal tube with a flexible profile. This construction allows the hose to accommodate movement in suitable piping installations. The manufacturer reference describes acid-resistant corrugated metal hoses with stainless steel braiding.
The exact corrugation profile, wall thickness, braid configuration and mechanical limits depend on the selected hose assembly. Confirm these details before using the product in a critical industrial system.
Stainless Steel Material and Braiding
The dedicated manufacturer reference identifies AISI 316L stainless steel for the inner bellows hose and AISI 304 stainless steel for the external braid.
The material grades should be checked against the conveyed medium, concentration, temperature and external environment. Chemical compatibility depends on the actual operating conditions and should be confirmed before selection.
Temperature Resistance
Metal hoses are used in applications involving demanding temperature conditions. The dedicated manufacturer page describes a temperature range from -270°C to +700°C, while the general Special Hoses page states an upper temperature capability of +550°C.
Because these manufacturer pages provide different upper limits, do not treat either maximum as applicable to every metal hose assembly. Confirm the approved temperature range for the selected diameter, material, braid, fittings and operating conditions before installation.
Pressure and Operating Conditions
Metal hose pressure capability depends on the hose diameter, corrugation, material thickness, braid construction, temperature and end connections. The supplied source does not provide a universal working-pressure rating for this product.
Request the manufacturer’s pressure rating for the exact assembly. Consider pressure surges, temperature effects, vibration, movement and installation geometry when assessing the system.
Vibration Absorption and Piping Movement
Metal hoses can be used to absorb vibration and accommodate deviations or movement in piping systems. They may be considered where connected equipment or pipework experiences movement that a rigid connection cannot accommodate.
Correct hose length, routing, alignment and bend radius are important. Avoid twisting, over-bending or imposing excessive mechanical loads on the assembly. Follow the manufacturer’s installation guidance.
Connection and End Fitting Options
The manufacturer describes metal hose assemblies that can be cut and welded with different thread and flange options. The correct connection depends on the equipment, pipework and service conditions.
Before ordering, confirm:
- Required thread or flange type.
- Connection size and dimensions.
- End fitting material and design.
- Welding and assembly requirements.
- Pressure and temperature compatibility of the complete assembly.
Testing and Quality Checks
The supplied manufacturer reference states that delivered metal hoses are leak-tested. It also describes pressure testing and additional tests, including X-ray inspection or third-party inspection, upon request.
Testing requirements should be agreed before ordering. Buyers can request the available test documentation and inspection records for the specific hose assembly.
Applications of Metal Hose
Metal hoses are used in industrial environments where flexibility, temperature capability, chemical resistance or vibration absorption are important. Potential application areas include:
- Industrial piping systems exposed to thermal movement.
- Equipment connections requiring vibration absorption.
- Process lines handling compatible liquids or gases.
- Industrial installations operating at demanding temperatures.
- Pipework requiring flexible connections between fixed components.
- Systems where stainless steel hose construction is required by the application.
These are general application areas for metal hose assemblies. Confirm material compatibility, pressure, temperature and approval requirements for the actual service before use.
Metal Hose Selection Guide
Consider the following factors when selecting a metal hose assembly:
- Conveyed medium: Identify the fluid or gas and confirm compatibility with the stainless steel grades.
- Temperature: Check both the operating and ambient temperature limits.
- Working pressure: Confirm the approved pressure rating at the operating temperature.
- Hose diameter: Match the internal diameter to the required flow and pipe connection.
- Braid construction: Confirm the number and design of braid layers required.
- Movement and vibration: Assess the amount and direction of movement the hose must accommodate.
- Connection type: Select compatible threads, flanges or welded end fittings.
- Inspection: Determine whether pressure testing, X-ray inspection or third-party inspection is required.
Industrial Buyer Guide
Procurement teams, plant engineers, maintenance departments and project contractors should provide complete system information when enquiring about metal hoses.
Share the conveyed medium, operating temperature, working pressure, internal diameter, hose length, connection type and expected movement. Include any applicable design standard or inspection requirement.
For critical piping systems, request the technical datasheet and assembly documentation. Confirm that the hose, braid and end fittings are suitable as one complete assembly rather than assessing the hose tube alone.
