The branch pipe and the other two diameters are called reducing tee. The reducing tee is generally a professional term, and the tee is a pipe fitting and a pipe connector, which is used at the main branch pipe of the main pipeline. The reducing tee is a kind of tee, and the tee has two kinds of general equal diameter tee and reducing tee. Named because the three ends can be connected to the tube. Those with the same diameter at both ends are called equal diameter tee. Reducing tees are widely used in the construction and maintenance of petrochemical, oil and natural gas, liquefied gas, fertilizer, power plants, nuclear power, shipbuilding, papermaking, pharmaceuticals, food hygiene, urban construction and other industries.
When connecting the reducing tee fittings, the flanged fittings and the parts that connect the fittings to each other are connected to the pipe ends. There are holes on the flanges, and bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Reducing tees refer to fittings with flanges. It can be cast, threaded or welded. The reducing tee connection consists of a pair of flanges, a gasket and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After tightening the nut, the specific pressure on the surface of the gasket will deform when it reaches a certain value, and fill the unevenness on the sealing surface to make the connection tight and leak-proof. Flange connection is a detachable connection.
Tee can be used in a variety of industries, and can be divided into the following categories according to different types:
According to the production method, it can be divided into top system, pressing, forging, casting, etc.
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.
