Applicable standards are different:
Different standard is applied for sanitary fittings and industrial pipe fittings, so you can say they are two different products. Sanitary Fittings includes DIN, SMS, ISO, IDF, 3A, RJT, DS, BS, ASME BPE etc. And then prevailing industrial pipe fittings are DIN and ASME / ANSI, as well as other smaller range of JIS, GB and other standards.
Working pressure is different:
Since sanitary piping systems is usually not so high pressures, the required of sanitary fittings is not high too. In fact, the wall thickness of sanitary fittings are relatively thin. And a lot of industrial pipe fittings are for poor working conditions and high corrosion resistance requirements, so their wall thickness should be heavy in comparison to sanitary fittings, and much more material grades.
Due to the development of science and technology, people are increasingly high requirements of the material. In today’s world, stainless steel applications are quite extensive and growing fast. We believe that with good corrosion resistance and high safety performance stainless steel sanitary fittings and industrial pipe fittings will be applied more widely due to the increased of safety awareness, and the green , health performance.
