Standard of Butt welding Tees
Butt welding tee is the connections of hot stamping or forging forming of steel plate. The connection method is to directly weld the tee and steel pipe. The main production standards of butt welding tees are generally GB/T12459, GB/T13401, ASME. B16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510.

Butt welding tees generally have equal-diameter tees, different-diameter tees, etc. The materials are carbon steel, alloy steel and stainless steel. Carbon steel tee When the chromium content of the steel reaches 1.2%, the chromium reacts with the oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the steel surface. The seamless tee can prevent further corrosion of the steel tube. In addition to chromium, commonly used alloying elements include nickel, molybdenum, titanium, niobium, copper, and nitrogen to meet various applications.
