Is Stainless Steel Pipe Safe For Drinking Water

Stainless steel pipe is the safest, healthiest, most environmentally friendly material in the world, which is most suitable for drinking water pipe.

Since 1980, Japan has vigorously promoted the use of stainless steel pipes and fittings, and now the popularity rate has exceeded 96%. American government ANSI / NSF61-1997a code rule: "for metal pipes used for drinking water, only stainless steel and ductile iron pipes are allowed." The current 2003 edition of the U.S. International Code Commission's plumbing and housing code is once again clear. Detroit's $300 million new Ford stadium's main water pipeline and direct drinking water pipeline are all made of 304 stainless steel. Since 1980, many stainless steel materials have been used in water system in Germany. Since 1995, Italian cities have adopted a technology that does not need to dig ditches to replace the main water pipeline with stainless steel pipeline. After 10 years of testing in Karlskoga, Sweden, the main pipes of nodular cast iron and PVC buried water supply have been replaced with 316 stainless steel pipes.

Why is stainless steel pipe used as drinking water pipe by countries all over the world?

1.There are many advantages of stainless steel pipe: 1. Hygiene: The inner wall has a high finish and is not easy to scale for long-term use, which fully meets the drinking water hygiene standards.

2. Corrosion: The whole tube is solution treated, the surface is pickled and passivated, and it is durable. Adding an insulating layer or an anti-corrosion layer has a better anti-corrosion effect.

3. High strength: The comprehensive strength is twice that of the galvanized pipe, three times that of copper pipe, and can withstand the water pressure of 10Mpa.

4. Light weight: The weight is 1/3 of the galvanized pipe, which is especially suitable for piping in high-rise buildings.

5. Low conductivity: Low heat conduction, 1/4 of copper tube, low thermal expansion rate.

6. Environmental protection: No pollution at the construction site, no pollution to the environment, 100% recycling.

7. Longevity: The service life is up to 70 years, which is in line with the building life. It does not need to be replaced and maintained for a lifetime, and the maintenance cost is low.

8. Saving: It is not easy to leak and save water resources.

9. Beautiful: high-grade and generous, the pipeline can be installed with dark cover. The insulation layer or the anti-corrosion layer may have different colors.

In a word, stainless steel material is safe and non-toxic, has no impact on water quality and is harmless to human health.
