    Three Major Characteristics of Sanitary Fittings

         Sanitary fittings are very popular in life as well. Sanitary pipe fittings can be broadly divided into sanitary-grade pipe fittings, sanitary-grade welded pipe fittings and socket-type sanitary pipe fittings and other three categories, although we may have a little understanding of sanitary pipe fittings, but may not understand its characteristics.

    Three Major Characteristics of Sanitary Fittings

    Three major characteristics of Sanitary pipe fittings

    1, corrosion resistance

    Many stainless steel sanitary fittings in food corrosion resistance are very good, such as one, two types of tableware, kitchen utensils, water heaters, drinking fountains, etc., there are many foreign businessmen for sanitary pipe corrosion resistance also tested: NACL solution heated to boiling, drained solution for a period of time, suction clean drying, said weight loss, to determine the degree of corrosion.

    2, Weldability

    Sanitary pipe fittings have different uses, the welding performance is also different. Some tableware on the welding performance does not require, including some pot enterprises. But the vast majority of production needs of raw materials, welding performance, such as the second category tableware, insulation Cup, pipe, water heaters, drinking fountains and so on.

    3, polishing performance (BQ)

    Sanitary pipe fittings polishing performance (BQ), at present, the stainless steel sanitary pipe fittings were polished in many industries, only a small number of products such as water heaters, drinking fountains, etc. do not need polishing. The raw material requirements are very important. 

    Factors affecting the polishing performance of sanitary pipe fittings:

    ① raw surface defects. Such as scratches, pitting, acid pickling.

     ② sanitary valves material quality problems. Hardness is too low, polishing is not easy to throw bright (BQ is not good), and hardness is too low, in the deep drawing surface prone to orange peel phenomenon, thus affecting the BQ. BQ hardness is relatively high.

    ③ After deep drawing products, the deformation of the surface area will be a great little black spots and RIDGING, thus affecting the BQ.
