不鏽鋼304被覆管（冷水） Stainless steel 304 flexible coating tube ( Cold Water )

304 Stainless Steel Coated Corrugated Tube
Premium Piping for Residential & Commercial Utility Systems

The 304 stainless steel coated corrugated tube is engineered as a highly durable, safe, and installation-efficient piping designed for gas supply lines, cold-water systems, and indoor plumbing renovation projects. Manufactured using certified Taiwan-origin 304 stainless steel, the tube features a stable and compliant nickel content that meets recognized international material standards, ensuring excellent strength, corrosion resistance, and long-term reliability in both indoor and outdoor environments.

To further optimize its performance, the stainless steel surface is processed through advanced high-brightness heat treatment. This treatment enhances oxidation resistance and prevents rust formation even in humid, chemical, or water-contact environments — making the tube ideal for both plumbing renovations and concealed service installations. The precision-corrugated structure delivers the perfect balance of flexibility and pressure-bearing capacity. It allows easy routing through tight areas, corners, and irregular construction space without kinking or deformation.

A specially engineered protective coating wraps the exterior of the stainless steel hose. This coating includes UV-resistant polymer additives, ensuring exceptional durability under continuous exposure to sunlight, rain, and fluctuating temperatures. The PE coating with anti-UV remains structurally stable without cracking, fading, or becoming brittle, maintaining consistent protection from harsh environmental conditions. Additionally, the tube incorporates an exclusive patented honeycomb-pattern layer on the inside, enhancing thermal performance by reducing heat loss and preventing surface condensation — offering greater operational efficiency compared to standard metal tube designs.

One key advantage of this product is its straight forward installation. The tube supports flexible bending up to 180 degrees without any special tools, significantly reducing installation time and labor cost, especially during retrofit work or when replacing rigid pipes. Its adaptability also allows better accommodation of building movements, reducing stress on joints and minimizing leakage risks.
