Equal tee is a tee, mainly used to branch pipe in the main line, widely used in petroleum chemical industry, petroleum and natural gas, liquefied gas, fertilizer, power plant, nuclear power, shipbuilding, papermaking, pharmaceutical, food sanitation, urban construction industries of engineering construction and maintenance. 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.
Equal 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 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.
There are a variety of industries, so different types can be divided into the following categories:
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.
Equal tee is on both ends of the same diameter, reducing tee branch pipe is called with other two different diameter reducing tee, said method is as follows: for equal tee, such as "T3" said three general principles of the outer diameter is 3 inches equal tee. 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 A403 etc., three-way, the outer diameter range is 2.5 "-60", from 26 "-60" to welding tee. Wall thickness of 28-60 mm.
Features of equal diameter tee:
1。 Advanced connection mode。 The connection mode is the integration hot melt connection, so in the embedding, it can avoid the leakage of the tube caused by the temperature change and the water hammer phenomenon。
2. Light weight, good flexibility and simple construction. The diameter of plastic and other diameter is 1/20 of galvanized steel tube, easy to handle, small bending radius is 6D.
3. Good resistance to cold and heat resistance. At 20 ℃, has good low temperature resistance, impact resistance equal tee not frost crack, after thawing, tubing can bounce back, resistant to high temperature below 100 ℃.
4. The wall is smooth without scale. Smooth inner wall, compared with galvanized pipe, can increase water flow 30%.
5. Good durability and non-toxic and harmless. Because it is polymer with polymer, the molecular structure is stable, the life can reach 50-100 years, and is not toxic and harmless.
6。 Energy conservation。 Good thermal insulation, plastic, etc。, can save 30% of energy when used for low temperature ground radiation。
7. Anti-ultraviolet, corrosion resistant. The anti-ultraviolet and microbiological damage of plastic, etc., will not have any effect on water quality.
