Three characteristics of sanitary pipe fittings 1. The use of weldable sanitary pipe fittings is different, and its welding performance is also different. Some tableware does not require welding performance, including some pot companies. However, most products require good welding performance of raw materials, such as Class II tableware, thermos cups, steel pipes, water heaters, water dispensers, etc. 2. Corrosion resistance. Many stainless steel sanitary pipe fittings have good corrosion resistance in food, such as first and second class tableware, kitchen utensils, water heaters, drinking fountains, etc. Many foreign businessmen are still very concerned about the corrosion resistance of sanitary pipe fittings. Tested: Heat the NACL water solution to boiling, pour out the solution for a period of time, suck clean and dry, and weigh the weight loss to determine the degree of corrosion. Causes rust spots on the surface during testing). 3. Polishing performance (BQ quality) Sanitary pipe fittings polishing performance (BQ quality). At present, many industries need to polish stainless steel sanitary pipe fittings. Only a few products such as water heaters and water dispenser tanks do not require polishing. It is very important in terms of raw material requirements.
