What are the properties and characteristics of sanitary pipe fittings

Jun 11, 2021|

Sanitary fittings are useful in many industries, such as food, storage, and transportation.Health grade pipe fittings are made of stainless steel, which can be divided into socket type health grade pipe fittings, health grade flange pipe fittings and health grade welded pipe fittings. Today I wants to share with you the three characteristics of health grade pipe fittings. Let's take a look

1. The welding performance of weldable sanitary pipe fittings is different due to their different uses.Some tableware does not require welding performance, including some pot enterprises.But the vast majority of products need raw materials with good welding performance, such as second class tableware, vacuum cups, steel pipes, water heaters, water dispensers and so on.

2. Corrosion resistance The corrosion resistance of many stainless steel sanitary pipe fittings in food is very good, such as one or two class tableware, kitchen utensils, water heaters, water dispensers, etc., there are many foreign businessmen for the corrosion resistance of sanitary pipe fittings have also done tests:NaCl aqueous solution is heated to boiling, the solution is poured out for a period of time, the solution is absorbed clean and dried, and the weight loss is weighted to determine the degree of corrosion (Note: when polishing the product, the surface of the abrasive cloth or sandpaper will appear rust spots due to the presence of Fen in it).

3, polishing performance (BQ) health grade pipe fitting polishing performance (BQ), at present, many industries of stainless steel health grade pipe fitting should be polished, only a few products such as water heater, water dispenser liner do not need polishing.In terms of raw material requirements are very important.Factors affecting the polishing performance of sanitary pipe fittings: surface defects of raw materials.Such as scratches, pitting, acid pickling, etc. Health grade pipe fittings material problem.If the hardness is too low, it is not easy to polish (BQ is not good), and the hardness is too low, the surface of the deep stretch is prone to appear orange peel phenomenon, thus affecting the BQ.BQ with high hardness is relatively good.(3) After deep stretching, small black spots and RIDGING will appear on the surface of the deformation area, thus affecting the BQ property.
