The concept of reducing tee: the diameter of branch pipe is different from the other two. The branches with same diameter are called as straight tee. Reducing tee are widely used in the construction and maintenance industries such as petrochemical, oil and natural gas, liquefied petroleum gas, fertilizer, power plants, nuclear power, shipbuilding, paper, pharmaceutical, food sanitation, urban construction projects.
The expression of reducing tee is as follows: For straight tee, "T3″ tee suggests outer diameter of straight tee is 3 inches; for reducing tee, "T4 × 4 × 3.5″ suggests the reducing tee with 4-inch same diameter and 3.5-inch different diameter.
The material of reducing tee is generally 10 # 20 # A3 Q235A 20g 16Mn ASTM A234 ASTM A105 ASTMA403. And, the outer diameter range of reducing tee is 2.5 " to 60″; the welding tee is from 26 " to 60″, whose thickness is 28 to 60mm.
The industry requirements of this reducing tee is relatively high, and the maximum pressure can reach to 600 kilograms, while the water pressure is low such as 16 kg.
