Stainless steel metal hose

Flexible, Corrosion-resistant Hose For High-pressure Systems

Stainless steel metal hoses offer flexible, corrosion-resistant solutions for high-pressure industrial piping, ensuring durability and vibration control in demanding applications.

Stainless Steel Metal Hose is a highly durable and flexible connector designed for industrial piping systems, offering exceptional corrosion resistance and reliability under high-pressure and extreme temperature conditions. Constructed from T321 or T316L stainless steel with single or double braiding (T304 or T316), these hoses are ideal for applications in chemical processing, oil and gas, HVAC, and boiler pipeline protection. Their corrugated design ensures flexibility, while the braiding enhances pressure capacity, making them suitable for flexible piping solutions in demanding environments.

Available in sizes from 1/4” to 24” (DN6 to DN600), stainless steel metal hoses handle pressures up to 3000 psi (depending on diameter and braiding) and temperatures from -320°F to 1500°F (-196°C to 815°C). They are designed to absorb vibration, accommodate misalignment, and resist abrasion, making them perfect for pipeline vibration control. The hoses are manufactured through annular or helical corrugation processes, with welded fittings (carbon steel, stainless steel, or custom alloys) to ensure leak-proof connections. They comply with standards like ISO 10380, ASME B31.3, and EJMA, ensuring quality and safety.

The corrosion resistance of stainless steel (T316L for enhanced chemical resistance, T321 for high-temperature strength) makes these hoses ideal for handling corrosive fluids, gases, and abrasive materials in industries like petrochemicals, refineries, and power generation. The braided construction provides burst resistance, with double-braided options offering higher pressure ratings for critical applications. These hoses are flexible enough for tight spaces and can be customized with liners for high-velocity flows to reduce turbulence and wear.

Compared to rubber or PVC hoses, stainless steel metal hoses offer superior durability and temperature tolerance, though they are heavier and costlier. Their ability to resist UV, ozone, and extreme climates ensures longevity in harsh environments. They are suitable for cryogenic applications, steam lines, and high-pressure gas transfer, with fittings like flanged, threaded, or welded ends for easy integration into industrial piping systems. Rigorous testing, including hydrostatic, burst, and fatigue tests, ensures compliance with industry standards and reliability in boiler pipeline protection.

Stainless steel metal hoses address challenges like pipeline wear, corrosion, and vibration in high-throughput industrial systems. Their robust, corrosion-resistant design and flexibility make them a preferred choice for engineers seeking reliable flexible piping solutions for extreme conditions, ensuring safety, efficiency, and long-term performance in applications like chemical transfer, steam piping, and oil and gas pipelines.

These hoses are constructed from thin-walled stainless steel tubes that are formed, welded, and corrugated to add flexibility and strength.

Stainless steel metal hoses offer advantages such as high temperature resistance, corrosion resistance, and durability. They are commonly used in industries like oil and gas, chemical processing, power generation, and food processing, where there is a need for reliable and flexible hose assemblies.

These hoses can be single braided or double braided with stainless steel wire braidings for added reinforcement. The braiding provides additional strength and protection against external damage.

Stainless steel metal hoses are available in various sizes, lengths, and pressure ratings to suit different applications. They are often used for applications that require flexible connections, vibration absorption, or where there is movement or misalignment between equipment.

When selecting a stainless steel metal hose, factors such as the type of fluid or gas being conveyed, operating temperature and pressure, and compatibility with the surrounding environment should be considered.

It's important to consult with a reputable manufacturer or supplier to ensure that the stainless steel metal hose chosen meets the specific requirements of the application.
