Our helical corrugated tube for Solar Thermal system is approved by UL(USA), RwTuv(Germany), NET(New Excellent Technology in Korea) & KS(Korea Standard), which means product quality is approved with reliability. It is supplied on wooden drum(endless roll type / length 25m ~ 300m). It is used as plumbing material for Solar hot water collector system in 3 different usage such as for heat-collecting pipe(black nickel plated tube) in the collector, water sending & returning tube between collector and hot water storage tank and heat-exchange coil tube in the hot water storage tank. Assembly at site is very simple and we’ve developed superb heat-resistant(350℃) thread-assembly type fitting which is world-first product.
- First : No leakage occurs even in 50,000 times of repetition test of heating(200℃) & cooling(-30℃).
- Second : Stainless steel 316L that is corrosion resistant against Anti freezing solution
(Calcium chloride, Sodium chloride) is used to prevent corrosion.
- Third : Helical type corrugation tube do not generate any vibration or noise of the tube.
- Forth : Assembly is more convenient than Copper tube(no welding work needed) and the price is
about 40% cheaper than Copper tube.
- Fifth : Thickness of Copper tube, heat-exchange coil inside of heat-storage tank, is 0.8mm while
stainless steel corrugation tube thickness is 0.3mm. Heat-exchange surface of stainless
steel corrugation tube is about 40% larger than Copper tube, which lead 33% reduction of
heat-exchange coil length (Both end of heat-exchange coil are welded to male or female
nipple that is to be welded to heat-storage tank chamber).
