Advantages Of Stainless Steel Pipe Fittings And Welding Precautions

Stainless Steel Weld Fittings is a widely used pipe fittings product. In order to meet the needs of the majority of users, it has also derived products such as stainless steel elbows, stainless steel tees, etc. These are collectively referred to as stainless steel pipe fittings, which are deeply loved and favored by people in the industry. Let Zhitong take you to understand the advantages of stainless steel pipe fittings and welding precautions.

Advantages of stainless steel pipe fittings:

1. It has good corrosion resistance and oxidation resistance.

2. The coating of stainless steel pipe fittings is divided into two categories, one is titanium calcium type and the other is low hydrogen type. The former can be used for AC and DC, and can turn red quickly during welding.

3. The welding rod should be kept dry during operation. The drying of titanium calcium type should be controlled at 150 degrees Celsius for 1 hour; the low hydrogen type needs to be at 200~250 degrees for 1 hour. During the drying process, it cannot be dried once, otherwise the coating will crack.

4. Stainless steel pipe fittings also have heat resistance and wear resistance, so they are equipped in chemical, power station, petroleum and other industries.

Welding precautions for stainless steel pipe fittings:

1. When welding stainless steel pipe fittings, heat treatment will precipitate carbides, reducing corrosion resistance and mechanical properties.

2. The welding current should not be too long, and the arc should not be too long, with narrow welds as the main focus.

3. Stainless steel pipe fittings are prone to cracks when welded, so welding requires heat treatment.

4. There should be no dirt on the surface of the electrode coating to avoid quality problems.
