EN 10312 Welded Stainless Steel Water Tube

BS EN 10312 welded stainless steel tube is produced for the conveyance of water and other aqueous liquids, primarily for water applications, EN 10312 is a European Standard covering welded stainless steel tubes with tight tolerances, including series 1 and series 2, the welded tubes can be finished in as welded, bright annealed and polished conditions.

Stainless steel tubes are more and more used for drinking water because of their excellent corrosion resistance and durable features. Stainless steel water pipes provide health and hygiene, safety and reliability, durability, energy saving, environmental protection and other advantages.

Stainless Steel Water Tube Advantages

• Healthful

SS Tube has a smooth inner surface, is not fouled for a long time use, is not easy to be stained with bacteria, no worry about water quality affected.

Stainless steel is a 100% renewable material that does not cause harm to the environment.

• Various Grades Selected

There are kinds of materials to meet the different conditions, like 304, 304L, and 316L, which have high strength.

• Durable And Cost Saving

The thin and dense chromium-rich oxide film on the surface of stainless steel makes water tube have good corrosion resistance in all water fluid including soft water, the corrosion test data shows that the stainless steel tube can be used for up to 100 years, with almost no maintenance is required during the life cycle, the cost and trouble of the tube replacement are avoided, and the comprehensive use cost is lower.

• High Temperature And Pressure Resistance

Whether it is high or low temperature, no harmful substances will be precipitated, and the material properties are quite stable; the high strength of stainless steel water pipes greatly reduces the possibility of leakage due to external forces and significantly reduces the water leakage rate.
