Butt-Welding Fittings C276 Equal Tee 1" SCH80 ASME B16.9

Equal diameter tee is the same diameter at both ends, and re-diameter tee is that the branch

pipe and the other two different diameters are called reducer tee, the representation is as

follows: for equal diameter tee, such as "T3" tee means that the outer diameter is 3 inches

of equal diameter tee. For reducer tees, for example, "T4×4×3.5" means a reducer tee with

a diameter of four inches and a diameter of 3.5 inches. The material is generally 10# 20# A3

Q235A 20g 20G 16Mn ASTM A234 ASTM A105 ASTM A403, etc., tee, outer diameter range

of 2.5"-60", from 26"-60" for welding tee. Wall thickness 28-60mm.

Because tees can be used in a variety of industries, they can be divided into the following

categories in different types:
1. Divide carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic,

argon asphalt, ppc, etc. by material.
2. According to the production method, it can be divided into topping, pressing, forging,

casting, etc.
3. According to the manufacturing standard, it can be divided into national standard, electric

standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
