不鏽鋼保溫軟管（熱水）Stainless steel 304 HDPE insulated pipe

304 Stainless Steel Insulated Flexible Hose
(Specialized for Solar Heating and Hot Water Systems)

The 304 Stainless Steel Insulated Flexible Hose is engineered to deliver long-term reliability and excellent thermal efficiency in demanding hot water and solar heating applications. Manufactured using high-grade 304 stainless steel coils sourced from certified steel mills in Taiwan, the hose provides a stable and sufficient nickel content that meets international material standards. This ensures superior corrosion resistance, mechanical strength, and durability even during continuous exposure to moisture, heat, and chemically reactive environments.

To further enhance material performance, the stainless steel undergoes a high-brightness heat treatment. This advanced surface process significantly improves oxidation protection, ensuring the hose maintains a clean finish and extended service life without rust or surface degradation. The corrugated construction offers excellent flexibility, supporting up to 180-degree bending without deformation. As a result, installation is faster, more adaptable, and ideal for complex layouts where traditional rigid piping is difficult to apply or requires costly labor.

This product features a proprietary multi-layer insulation structure, including a patented internal honeycomb-pattern thermal barrier. The innovative geometry minimizes heat loss during transfer and maximizes energy efficiency, providing a stable hot-water supply from the source to the point of use. Additionally, the outer protective insulation layer incorporates UV-resistant materials, specifically designed for long-term outdoor exposure. It prevents aging, cracking, and degradation caused by sunlight, rain, and climate variation—making it ideal for rooftop installations and high-intensity environmental conditions.

Available Sizes:
16 / 18 / 20 / 25.5 mm
(Equivalent to 3/8", 1/2", 3/4", and 1")
