DN25-DN100 Stainless Steel Metal Hose
DN25-DN100
This stainless steel metal hose series (DN25–DN100) is built from premium austenitic stainless steel, offering outstanding corrosion resistance, high-temperature tolerance, and mechanical durability for demanding fluid and gas applications. Its corrugated core ensures excellent flexibility, vibration absorption, and thermal expansion compensation, while the outer wire braid provides robust burst protection and axial stability. Fully customizable end connections and optional covers adapt to various piping systems, with pressure ratings up to 40 bar and temperature ranges from –196°C to +600°C. Manufactured under strict quality standards and fully tested, these hoses deliver reliable, leak-free performance in confined installations and harsh industrial environments.

This stainless steel metal hose series, covering nominal bore sizes from DN25 through DN100, is engineered for reliable fluid and gas transfer across demanding industrial environments. Constructed entirely from high-grade austenitic stainless steel, the hose offers exceptional resistance to corrosion, high temperatures, and mechanical fatigue, making it suitable for applications involving steam, hot oils, chemicals, cryogenic media, and exhaust systems.
The hose features a precision-wound, annular or helical corrugated core that provides outstanding flexibility while maintaining pressure integrity under dynamic conditions. This corrugated design effectively absorbs vibration, compensates for thermal expansion, and accommodates misalignment in piping systems, thereby reducing stress on connected equipment and extending overall service life. Depending on the model, the inner hose is available with a smooth or deeply corrugated bore to optimize flow characteristics and minimize pressure drop.
To enhance durability and safety, the hose is complemented by a heavy-duty stainless steel wire braid—single or double layer—which acts as a protective armor against external mechanical damage, burst pressure, and torsional forces. The braid also limits axial elongation under pressure, ensuring stable performance even in pulsating or surge-prone systems. For applications requiring additional abrasion resistance or thermal insulation, optional covers in PVC, silicone, or stainless steel overbraid can be specified.
End connections are fully customizable to meet diverse installation requirements. Standard options include fixed or swivel flanges in accordance with DIN, ANSI, or JIS standards, as well as threaded male/female fittings, butt-weld ends, and quick-release couplings. All terminations are welded or crimped using specialized techniques to guarantee leak-free joints and maximum pull-off resistance.
The entire product range is manufactured under strict quality control systems, with each hose subjected to hydrostatic proof testing and, where required, pneumatic leak testing prior to dispatch. The hoses comply with international standards such as EN 13480, ASME B31.3, and PED 2014/68/EU, ensuring traceability and full material certification upon request.
Operating temperature range spans from –196°C up to +600°C, depending on the grade of stainless steel selected (AISI 304, 316L, or 321). Working pressure ratings vary with hose diameter and braid configuration, with DN25 models typically rated up to 40 bar and DN100 variants up to 16 bar at ambient conditions. For high-pressure or vacuum service, reinforced multi-braid or interlocked hose constructions are also available within the same size range.
Routine maintenance is simplified by the hose’s smooth external surface, which resists dirt accumulation and allows easy visual inspection. With a minimum bending radius as low as 5 times the nominal diameter for DN25 and progressively larger for larger sizes, these hoses offer installation versatility in confined spaces without compromising flow capacity.
Backed by comprehensive technical support, each delivery includes installation guidelines and torque recommendations for fitting assemblies. Custom lengths, special end fittings, and alternative material grades can be supplied on request to suit unique process conditions, ensuring that every system benefits from optimal performance, safety, and longevity.
