Overview
Product Overview
The Stainless Steel Flexible Metal Hose by Quanyi Rubber is an advanced, high-reliability flexible connection component engineered for demanding industrial pipeline systems. Designed to operate where conventional rubber or plastic hoses fail due to severe temperature, pressure, or chemical attack, this metal hose offers superior flexibility, fatigue resistance, and extended service life.
Constructed with a premium austenitic stainless steel inner core (SS304, SS316, SS316L, or SS321) featuring an annular circular ripple profile, the hose guarantees maximum structural strength, smooth flow, and resistance to vacuum collapse. For high-pressure integrity, the exterior is reinforced with one or two layers of high-density SS304 or SS316L wire braid, dynamically engineered based on system pressure requirements.
Capable of withstanding extreme temperature environments ranging from -200°C to +600°C and outer diameters from 10mm to 300mm, our flexible metal hoses absorb mechanical shock, thermal expansion, and pipeline vibration. Welded with precision fittings according to global standards (ASTM, AISI, DIN, EN, GB, JIS), Quanyi metal hoses ensure zero diffusion and seamless fluid transfer in high-consequence industrial applications.
