Product Specification

ANSI B16.9 S2205 SCH 40S 3" High Quality Pipe Fitting Stainless Steel Tee Pipe Connector High Temperature Resistant Tee

2205 duplex stainless steel is a duplex stainless steel composed of 22% chromium, 3% molybdenum and 5-6% nickel nitrogen. It has high strength, good impact toughness and good overall and local stress corrosion resistance. Compared with 316L and 317L austenitic stainless steel, 2205 alloy has superior performance in pitting and crevice corrosion resistance. It has high corrosion resistance. Compared with austenite, its thermal expansion coefficient is lower and heat conduction. Higher sex.
The yield strength of 2205 is twice that of austenitic stainless steel. This feature enables designers to reduce weight when designing products, giving this alloy a more price advantage than 316 and 317L. This alloy is particularly suitable for the temperature range of -50°F/+600°F. For applications beyond this temperature range, this alloy can also be considered, but there are some limitations, especially when applied to welded structures.

2205 stainless steel tee is a pipe fitting used for pipe branching.

Stainless steel tee fittings are widely used in chemical, civil engineering, machinery manufacturing, shipbuilding industry and other fields because of their convenience and simplicity.

There are usually two processes of hydraulic bulging and hot pressing to make tees with seamless pipes. What is the forming process of stainless steel tee?

1. Hot press forming of three-way ball valve

The hot press forming of stainless steel tee pipe fittings is to flatten the tube blank larger than the diameter of the tee pipe to the size of the tee pipe diameter, and open holes on the stretched branch pipe;

The tube blank is heated, the tube blank is placed in a forming mold, and a mold for stretching the branch tube is installed in the tube blank; under the action of pressure, the tube blank is radially compressed.

In the process of radial compression, the metal flows to the branch pipe, forming the branch pipe under the stretching of the mold.

The whole process is formed by the radial compression of the tube blank and the extension of the branch tube.

Hydraulic bulging of 2.2205 hot-pressed tee

The hydraulic bulging of 2205 duplex stainless steel three-way pipe fittings is a forming process in which the branch pipe is expanded through the axial compensation of the metal material.

In this process, a hydraulic press is used to inject the liquid into the billet with the same diameter as the tee, and the two horizontal side cylinders of the hydraulic press are synchronized to move and extrude the billet;

The pressure of the liquid in the tube blank increases as the volume of the tube blank decreases.

The forming process of the stainless steel tee is mainly as described above. We should all know the forming process of stainless steel tee;

We all need to operate in accordance with the forming process of stainless steel tee.
