Product Features
Stainless Steel Construction:
Our metal hoses are made from AISI 316 or AISI 304 stainless steel, offering excellent corrosion resistance, strength, and durability. These materials are perfect for withstanding harsh environments, including saltwater exposure and chemical interactions.
Corrugated Inner Tube:
The corrugated tube design enhances flexibility and allows the hose to absorb vibration, movement, and thermal expansion. This ensures smooth fluid flow while minimizing the risk of kinks or blockages.
Optional Braided Layer:
For added protection, we offer an optional braided stainless steel outer layer. This reinforcement increases the hose’s ability to withstand higher pressures, resist external abrasions, and improve the overall mechanical strength of the hose.
High Temperature and Pressure Resistance:
Designed to perform in extreme conditions, our metal hoses can operate within a temperature range of -200°C to +700°C and handle pressure ratings up to 40 bar, ensuring reliability in both high-temperature and high-pressure applications.
Chemical and Abrasion Resistance:
Our hoses are resistant to a wide variety of oils, fuels, chemicals, and abrasives, making them ideal for applications in the chemical, petrochemical, and industrial sectors where exposure to harsh substances is common.
Applications
Marine: Essential for fuel lines, hydraulic systems, ballast water systems, and exhaust gas systems aboard ships, offshore rigs, and marine platforms.
Petrochemical: Used for fluid and gas transfer in refineries, chemical plants, and pipelines, ensuring safe handling of oils, fuels, and chemicals.
Industrial: Perfect for high-pressure fluid systems, hydraulic lines, and gas transport in manufacturing, automotive, and heavy machinery industries.
Aerospace: Ideal for fluid transfer systems, cooling, and fuel lines in aircraft, where performance under pressure and extreme temperatures is critical.
