- 商品名稱: ASME American Standard Tee
ASME American standard tee belongs to a kind of pipe fittings, tee is also called pipe fitting tee or tee fitting, tee joint, etc. The tee is mainly used to change the direction of the fluid, and is used at the branch pipe of the main pipeline. The tee is divided into TS equal diameter tee and TR reducing tee, equal diameter tee main pipe and branch pipe tee with the same diameter, reducing tee branch pipe diameter is smaller than the main pipe diameter tee. The tee is divided into regular tee and ASME American standard tee according to the form of the branch pipe. The positive tee is the tee fitting for the vertical main pipe of the branch pipe, and the ASME American standard tee is the tee fitting with a certain angle between the branch pipe and the main pipe. ASME American standard tee can be divided into seamless tee (refer to GB/T12459-2017) and plate ASME American standard tee (refer to GB/T13401-2017) according to the processing technology. Three-way pipe fittings are used in places where the pipeline has branches. Because of its convenient and simple use, it is widely used in chemical industry, civil construction, machinery manufacturing, shipbuilding industry and other fields.
Tee is divided into carbon steel, stainless steel, alloy steel, special alloy steel, duplex stainless steel, etc.; carbon steel: (20#, A3, Q235, Q235A, Q235B, 20G, 16Mn, Q345, Q345R, ASTM A234WPB, ASTM A105 etc.); stainless steel: (304, 304L, 316, 316L, S30408, S30403, S31608, S31603, SUS304, ASTM A403, TP321, TP317L, 347, 0Cr18Ni9, 00Cr19Ni10, 00Cr17Ni14:Mo2, 1Cr18Ni9Ti, 06Cr17Ni12Mo2, etc.); (16MnR, Cr5Mo, 12Cr1MoV, 10CrMo910, 15CrMo, 12Cr2Mo1, A335P22, St45.8/Ⅲ, A10bB, etc.); Special alloy steel: (TP310S, 904L, Incoloy800, Incoloy825, Incoloy600, Incoloy625, etc.); Duplex stainless steel: (F51 , S31803, S2205, F53, 2507, S32750, F55, 2607, S32760, etc.).

The processing and forming process of the tee, the forming of the tee joint is to flatten the tube blank larger than the diameter of the tee to the size of the diameter of the tee, and open a hole in the part where the branch pipe is stretched; the tube blank is heated and put into the forming die The tube blank is radially compressed under the action of pressure, and the metal flows in the direction of the branch pipe during the radial compression process and forms the branch pipe under the stretching of the die. The whole process is formed by the radial compression of the tube blank and the stretching process of the branch pipe. Different from the hydraulic bulging tee, the metal of the branch pipe of the tee joint is compensated by the radial movement of the tube blank, so it is also called the radial compensation process. Since the tee is pressed after heating, the tonnage of the equipment required for material forming is reduced. Hot-pressed tee has wide adaptability to materials and is suitable for low carbon steel, alloy steel and stainless steel materials; especially for tee with large diameter and thick wall, this forming process is usually used. The high-pressure tee generally adopts the forging process, and the forging process is complicated and needs to be processed according to the drawing.- ASME American Standard Tee
