304 is a section supervisor plus a small branch tube, obviously, two large dimensions are the supervisor, the secondary secondary small size is the branch pipe. It can be used to connect the pipe diameters of different pipe diameters or in different directions. Reducing tee is widely used in petrochemical, oil and natural gas, liquefied gas, fertilizer, power plant, nuclear power, shipbuilding, papermaking, pharmaceutical, food sanitation, urban construction industries of engineering construction and maintenance.

The method is as follows: for equal diameter tee, such as "T3", the outer diameter is 3 inches. For different diameters, such as "T4 x 4 x 3.5", the same diameter has a diameter of 3.5 inches. The material is generally 10# 20# A3 Q235A 20g 20g 20g 16Mn ASTM A234 ASTM A105ASTMA403, etc., three-way, the outer diameter range is 2.5 "-60", from 26 "-60" to welding tee. Wall thickness of 28-60 mm.

The pressure of this kind of pipe is high in industry, the pressure can reach 600 kilograms, the water pipe pressure in life is low, generally 16 kilograms.

Tee pipe fitting and pipe fitting. Use a branch in the main pipe.

1. To divide carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PPC, etc.

2. It can be divided into top system, pressing, forging, casting and so on.

3. The division of manufacturing standards can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.

304 reducing tee features are: reasonable design, novel structure, using the convenient operation and can reduce the wear and tear for connecting hoses, thus increasing service life, reduce the production cost, can deal with the issue of workers take pressure homework at the same time, is advantageous to the safety production. In other words, it is only a small part, but for the development of industry, he has important meaning and function. The elastic of spare parts, aging, length of life, etc., have important influence on this equipment. User, must check the parts regularly, and maintain, can use lubricants to wipe, extend part life.
