Main pipe body:stainless steel 304, 316, Corrugated pipe Protection: PVC or PE wrapping material Fittings: stainless steel 304, Screw connection All these parts make a strong durable pipeline system. @ Willie floor heating composite pipe The company of Willie produces stainless steel flexible composite pipe is used t the high-quality stainless steel 304 material, flexible composite pipe,is with a special processing it has excellent thermal conductivity, high temperature, high pressure, aging, etc., equipped with stainless steel connecting tubes and system components, on-site construction is easy, quick and easy installation, then use of the normal life is up to 70-100 years. the characteristics of stainless steel warm flexible tube 1, watertight : tensile strength ≧ 530N / mm ² is normal to warm the pipe 2 to 10 times; thermal expansion coefficient of 17.3, from the environment and temperature control 2, non-scaling :in -20 ~ 120 water temperature does not scale, one time investment, a lifetime benefit, the same life expectancy with the buildings (70 years). 3, to facilitate the construction - minimum bending radius of 4 cm, extremely flexible, more convenient.than the average of the warm pipe construction 4, water resistance, energy saving – Willie processed 304 cold rolled coil ultra-low carbon stainless steel pipe, wall finish high. Noscale, but also reduces the flow resistance coefficient, can be bent and the constant flow of the advantages of saving energy 1 / 2. 5, 100% environmentally friendly recyclable
