Carbon Steel ASME B16.9 Pipe Fitting Tee Seamless Straight/Reducing Tee

Carbon steel tee is also a kind of pipe fittings, generally there are two kinds. Equal-diameter tee with the same diameter at both ends, and branch pipes with different diameters are called reducing tee.

The representation method is as follows

For equal diameter tees, for example, "T3" (3 inches = DN80) tee means equal diameter tees with an outer diameter of 3 inches. For reducing tees, such as "T4×4×3.5" (4 inches = DN100, 3.5 inches = DN90) means that the same diameter is four inches and the different diameter is 3.5 inches. The material is generally 10# 20# A3 Q235A 20g 20G 16Mn ASTM A234 ASTM A105 ASTM A403, etc., three links, the outer diameter range is 2.5 "-60" (2.5 inches = DN65, 60 inches = DN1500), wall thickness 3-60mm, From 26 "-60" (26 inches = DN650, 60 inches = DN1500) for welding tee. The wall thickness is 28-60mm. The pressure ratings are Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS.

DN15 to DN800 generally implement the GB/T12459-2005 standard in China.

The bigger one is the seam welded tee, the implementation standard is GB/T13401-200
