Stainless steel extraction tube is the best direct drinking water delivery pipe.
Thin-walled stainless steel water pipes, with low leakage rates, can save precious water resources.
The leakage rate of water pipes in the 1980s was about 17%, but after the switch to stainless steel pipes, the leakage rate dropped to 7%.
Compared with cupreous conduit, the water of stainless steel conduit is good and does not corrode below the circumstance with a high flow rate.
Its insulation is also 24 times that of copper pipe, which is very cost-effective.
