What Is The Difference of Stainless Steel Sanitary Fittings and General Industrial Pipe Fittings
The Difference Between Stainless Steel Sanitary Fittings and General Industrial Pipe Fittings
As an important component of the piping system, pipe fittings used more widely and the demanding is increasing every day. Nowadays, according to the different fields of use, stainless steel pipe fittings have been divided into stainless steel sanitary fittings , stainless steel industrial fittings, stainless steel instrument fittings and so on. So what is the difference of stainless steel sanitary fittings and general pipe fittings? Let’s make a general analysis.
Applicable field is different:
Sanitary fittings mainly used in food and beverage, brewing, pharmaceutical and other high purity equipment and process requirements. The industrial pipe fittings mainly used for oil pipelines, chemical engineering, shipbuilding, seawater desalination and other areas, not so much for its precision and cleanliness requirements, the more consideration is corrosion-resistant of stainless steel.
The surface condition is different:
Sanitary fittings usually have high finish requirements of internal and external surface, such as mirror-polished, dulled, brushed and so on. Of course there are pickled surface or casting surface of sanitary clamps too, but this is not the usual treated for hygienic fittings . About industrial stainless steel pipe fittings, the surface is usually no special treatment, pickling is general surface.
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.
