Large caliber seamless tee

Large caliber seamless tees require less equipment tonnage for material forming due to the use of heated and pressed tees. Hot pressed tees have a wide adaptability to materials and are suitable for materials such as low carbon steel, stainless steel, and alloy steel; Especially for tees with large diameters and thick pipe walls, this forming process is usually used. There are several classifications:
Divided by material, carbon steel, cast steel, alloy steel, copper, aluminum alloy, plastic, stainless steel, argon chromium plating, PPC, etc.
According to the production method, it can be divided into top making, forging, casting, pressing, etc.
According to manufacturing standards, it can be divided into national standards, water standards, American standards, electrical standards, German standards, Japanese standards, Russian standards, etc.
Technical requirements for large-diameter elbows: 1. As most pipe fittings are used for welding, in order to improve welding quality, the ends are chamfered, leaving a certain angle and with certain edges. This requirement is also quite strict, with regulations on how thick the edges are, what the angle is, and the deviation range The surface quality and mechanical properties are basically the same as pipes For the convenience of welding, the steel grade of the pipe fittings is the same as that of the connected pipes Classification of large diameter elbows: Divided by angle, the most commonly used ones are 45 °, 90 °, and 180 °. In addition, according to engineering needs, other abnormal angle large diameter elbows such as 60 ° are also included
