Product Description
Alloy 20 Introduction
Alloy 20 is an austenitic stainless steel containing less than 50% iron and is used in applications involving sulfuric acid. Its
corrosion resistance also finds other applications in the chemical, petrochemical, power generation, and plastics industries.Alloy 20 exhibits superior resistance to pitting and chloride ion corrosion compared to 304 stainless steel and is comparable to316L stainless steel. Its copper content protects it from sulfuric acid. Alloy 20 is typically selected to address the potentialstress corrosion cracking issues of 316L stainless steel.

Alloy 20 Butt Welding Straight Tee Introduction
The three-way fitting, also known as the three-way pipe fitting or three-way pipe component, three-way connector, etc. It is
mainly used to change the direction of the fluid and is installed at the point where the main pipeline needs to branch off. It can be classified according to the pipe diameter. Generally, it is made of carbon steel, cast steel, alloy steel, stainless steel,
copper, aluminum alloy, plastic, asbestos felt, PVC, etc. According to the connection form, it can be divided into:

1.Butt-welded three-way fitting: It refers to the three-way pipe fitting that is welded after being connected with the connecting pipe fittings.
2. Socket-type three-way pipe fittings: These are pipe fittings where the connecting pipe pieces are inserted into each end of the three-way pipe and then welded or fused together.
2. Socket-type three-way pipe fittings: These are pipe fittings where the connecting pipe pieces are inserted into each end of the three-way pipe and then welded or fused together.
3. Socket-type three-way fitting: This is a type of three-way pipe fitting where each end is a socket joint. The pipe fittings are inserted into the sockets and then tightened.
4. Threaded Three-way Pipe Fittings: Three-way pipe fittings that are connected by threads.
By material classification
It can be classified into stainless steel three-way valves, carbon steel three-way valves, copper three-way valves, PVC three-way valves, ductile iron three-way valves, etc.
According to the form of branch pipes
1. Straight three-way fitting: It is a pipe fitting where the branch pipe is perpendicular to the main pipe.
2. Inclined Three-way: This refers to a three-way pipe fitting where the branch pipe forms a certain angle with the main pipe.

Butt Welding Straight Tee Processing
1. Hydraulic bulging
The hydraulic bulging of the butt welded tee is a forming process in which the branch pipe is expanded by the axial compensation of the metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the welded tee. The two horizontal side cylinders of the hydraulic press synchronize the centering movement to extrude the tube blank. The volume of the tube blank becomes smaller after being squeezed, and the inside of the tube blank The pressure of the liquid increases as the volume of the tube becomes smaller. When the pressure required for the expansion of the three-way branch tube is reached, the metal material flows along the inner cavity of the mold under the dual action of the side cylinder and the liquid pressure in the tube blank to expand the branch tube.
The advantages of the hydraulic production process of the welded tee are that it can be formed at one time, the production efficiency is high, and the wall thickness of the welded tee is uniform.
2. Hot press forming
Hot press forming of butt welded tee is to flatten the tube blank larger than the diameter of the tee to the size of the diameter of the butt welded tee. Because of the higher cost and the same quality as the hydraulic welded tee, it is not commonly used.
3. Cold drawn tee
Open a hole in the butt welding tee where the branch pipe needs to be stretched. After heating, the tube blank is put into the forming die, and the blank tube is inserted into the punching die for stretching the branch tube; the tube blank is radially compressed under the action of pressure. In the process of radial compression, the metal flows in the direction of the branch pipe and forms the branch pipe under the stretching of the die. The whole process is formed by the radial compression of the tube blank and the stretching process of the branch tube. Different from the hydraulic welding tee, the metal of the hot-pressed tee branch is compensated by the radial movement of the tube blank, so it is also called the radial compensation process. This production process is usually used for the production of large-size welded tees and thick-walled welded tees, whether it is carbon steel, stainless steel or alloy steel.
4. Use multiple pipe parts for welding
The steel pipe is cut into multiple suitable pipe parts, and then welded the pipe parts together. Butt welded tees are used for irrigation pipelines. This is usually used for special-sized pipes and is produced according to Eathu customer drawings.
The surface treatment of this butt welding tee usually has special requirements and is customized according to customer needs.
