Why Stainless Steel?
Recyclable
Unlike cement lined and non-metallic pipe, Stainless Steels are easily recycled and their alloy content is highly valued. Recycled stainless steel and other recycled ferrous materials are used in the melting process to produce Stainless Steel, which has an average recycled content of approximately 60%.
Low Leakage Rates
Stainless Steels do not suffer from uniform corrosion like their ductile iron or steel counterparts, which can result in the rupture and failure of pipelines. Fully welded or fully restrained stainless steel joints can lower leakage rates.
Hygienic
Due to their protective passive film Stainless Steels are basically inert in potable waters, which maintains water quality and drinking water integrity. Stainless Steels are used for high purity pharmaceutical water and ANSI/NSF drinking waters.
Extended Service Life
Stainless steel components can provide 100 years of service due to their excellent corrosion resistance and ductility at all service temperatures.
Environmental Effects
– Temperature – As operating temperatures decrease, ductile iron, carbon steel and non-metallic pipes decrease in impact strength and become more brittle. Brittle water main failures may result during low temperature weather conditions. Stainless Steel remains ductile and flexible at all temperature exposures.
– UV Resistance – Stainless Steel properties are not affected by exposure to UV light, which will degrade non-metallic pipe.
– Soil Corrosion – Stainless Steels resist corrosion in most soils and do not require coatings or electro chemical protection systems.
