Three characteristics of sanitary pipe fittings

Three characteristics of sanitary pipe fittings Sanitary pipe fittings are useful in many industries, such as food, storage and transportation. The sanitary pipe fittings are made of stainless steel, which can be divided into three categories: socket sanitary pipe fittings, sanitary flange pipe fittings and sanitary welded pipe fittings. Today, I want to share with you the three characteristics of sanitary pipe fittings. Let's take a look

1. The weldability of sanitary pipe fittings is different due to different uses. Some tableware do not require welding performance, including some pot enterprises. But most products need good welding performance of raw materials, such as Class II tableware, insulated 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 Class I and II tableware, kitchenware, water heaters, drinking fountains, etc. Many foreign businessmen have also tested the corrosion resistance of sanitary pipe fittings: use NACL aqueous solution to heat to boiling, pour out the solution for a period of time, suck it clean and dry it, weigh the weight loss, To determine the degree of corrosion (Note: when the product is polished, the abrasive cloth or abrasive paper contains Fe, which will cause rust spots on the surface during the test).

3. Polishing performance (BQ) Polishing performance (BQ) of sanitary pipe fittings. At present, many industries need to polish stainless steel sanitary pipe fittings, and only a few products, such as water heaters, water dispenser liners, do not need polishing. It is very important in terms of raw material requirements.

Factors affecting the polishing performance of sanitary pipe fittings: 1. Surface defects of raw materials. Such as scratches, pitting, pickling, etc. 2. The raw material of sanitary pipe fittings is defective. If the hardness is too low, it is not easy to polish when polishing (poor BQ property), and if the hardness is too low, orange peel is easy to appear on the surface during deep drawing, which affects the BQ property. BQ with high hardness is relatively good. 3. After deep drawing, small black spots and RIDGING will appear on the surface of the area with great deformation, which will affect the BQ property.
