Forming Method And Manufacturing Standard Of Tees In Stainless Steel Pipe Fittings

Stainless steel tees are actually a connector for stainless steel pipe fittings and pipes, and are mainly used when the main pipe needs to branch. Stainless steel tees are also divided into equal diameter and different diameter. Generally, the ends of the pipes of equal diameter tees are of relatively the same size, while the sizes of the main pipes of different diameter tees are the same, and the pipe sizes of the branch pipes are smaller than the pipe sizes of the main pipes. The hydraulic bulging of stainless steel tees is a forming process that expands the branch pipes through the axial compensation of metal materials.

2. What are the types of stainless steel tees?

1. Extruded stainless steel tees: The usual production processes include hydraulic bulging and hot pressing. Both of these production processes make the steel pipe sections plastically deform according to the tee mold without destroying the metal structure, thereby producing the designed tee.

2. Welded stainless steel tees: They are welded from multiple steel parts. This type of stainless steel tees can be divided into three types: elbow type, right angle type and flat weld. Their appearance shapes are different, but the welding process is basically the same, except that the shapes of the welded steel parts will be different.

3. What is the standard of Stainless Steel Weld Tee?

Although it has production and manufacturing standards like hardware accessories, it generally stipulates some specific requirements from production to manufacturing from multiple aspects. However, the standards for stainless steel tees are different in different countries or regions. The following examples are given:

1. National standard: GB/T12459, GB/T13401

2. Electrical standard: ASMEB16.9

3. Water standard: SH3408, SH3409

4. Chemical standard: HG/T20592

5. German standard: DL/T695

6. Japanese standard: SY/T0510

7. Russian standard: DIN2615
