The tee is a pipe fitting and a pipe connecting piece. Also known as pipe fitting tee or tee pipe fitting, stainless steel equal diameter tee joint, used at the main branch pipe of the main pipeline. A tee is a chemical pipe fitting with three openings, that is, one inlet and two outlets; or two inlets and one outlet. Where three identical or different pipelines converge. The main function of the tee is to change the direction of the fluid.

For the use of seamless pipes to manufacture tee, the currently commonly used processes include hydraulic bulging and hot pressing. The hydraulic bulging of the stainless steel tee is a forming process that expands the branch pipe through the axial compensation of the metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and to extrude the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The pressure of the liquid increases as the volume of the tube blank becomes smaller when the pressure required for the expansion of the stainless steel tee branch pipe is reached. Even buried in the ground has excellent corrosion resistance, and it is constantly used and promoted in different environments and sites. Therefore, it is suitable for all kinds of water quality. In addition to disinfection and sterilization, it does not need to control the water quality. At the same time, there is no corrosion and excessive exudate. It can keep the water quality pure and hygienic, prevent secondary pollution, and can withstand heights of up to 30 meters per second. Water impact. It can ensure the safety and non-polluting of water quality in different fields and industries and play an important role in different places. Has excellent mechanical and physical properties. The strength of the seamless tee is very high, which is 3 times that of copper pipe and 8-10 times that of PP-R pipe. , so it is very safe and reliable; at the same time, it has good thermal insulation performance, is especially suitable for hot water transportation, and plays an important role in linking. Large-diameter national standard tee is generally divided into equal-diameter tee and reducer, and the materials are carbon steel and alloy steel.

Tee material: 304 stainless steel  Product specification: DN15——DN250   Representation method: Reducing tee such as “T4×4×3.5” means a reducing tee with a same diameter of four inches and a different diameter of 3.5 inches.

Reduced-diameter tee: The branch pipe with different diameters is called a reduced-diameter tee. Those with the same diameter at both ends are called equal diameter tee.

The reducing tee is generally professional, 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 generally has two kinds of equal diameter tee and reducing tee.

In the industry, the pressure of reducing tee is relatively high, and the maximum pressure can reach 600 kg. In life, the pressure of the water pipe is relatively low, generally 16 kg. Used in different places, play an important role. Has excellent mechanical and physical properties. The strength of the seamless tee is very high, which is 3 times that of copper pipe and 8-10 times that of PP-R pipe. , so it is very safe and reliable; at the same time, it has good thermal insulation performance, especially suitable for hot water transportation, and plays an important role in linking. The function of the large-diameter high-pressure tee is to change the direction of the fluid, which can divide the fluid in the main pipeline into other two or three pipes, which can be of the same diameter, or can be made of different diameter tees, four-way, different pipes according to requirements. The size of the main pipe interface of the diameter tee is the same, the size of the branch pipe is smaller than that of the main pipe, and the products with large diameter pipes and thick walls are usually formed by hot pressing, which can ensure the accuracy and pressure of the products.

A high-pressure seamless tee is a kind of pipe fitting. Hot-pressed tee is a kind of tee made by the hot-pressing process. The hot-pressed tee is a method of heating the tube and processing it with professional equipment and then cutting and heating it to a temperature above the critical temperature. Three links were made. Treatment method Quenching is to heat the tee to a temperature above the critical temperature, hold it for a period of time, and then quickly put it into the quenching agent, so that the temperature is suddenly reduced, and it is rapidly cooled at a speed greater than the critical cooling rate, and the martensite is obtained. The heat treatment method of the unbalanced structure. Reducing tee: Reducing tee is a kind of tee, which is the connecting part of pipe fittings and pipes. All three ends can be connected with pipe fittings. When the diameter of the branch pipe and the other two pipe fittings is different, the required tee is different. Diameter tee. Special-shaped tee fittings and general-purpose tee fittings The special-shaped tee fittings with the same shape, length and dimensions have internal and external threaded end interfaces. Thereby reducing accessories, reducing movable interfaces, simplifying construction procedures, and improving the tightness of pipelines. Therefore, the three-way valve requires the steel pipe to have high lasting strength, high oxidation resistance, and good organizational stability. The steel grades used are: high-quality carbon structural steel grades 20G, 20MnG, 25MnG; alloy structural steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; 1Cr18Ni1Cr18Ni11Nb high-pressure boiler tubes are commonly used in rust and heat-resistant steels. In addition to ensuring chemical composition and mechanical properties, water pressure tests, flaring and flattening tests are required one by one. . Steel pipes are delivered in the heat-treated condition. In addition, there are certain requirements for the microstructure, grain size and decarburization layer of the finished steel pipe. Pipe fittings Thin-walled stainless steel pipe fittings, which began to be produced and used in China in the late 1990s, are a new and emerging family in the field of pipes today and have been widely used in pipelines for building water supply and direct drinking water. Thin-wall stainless steel fittings are durable.

Three common problems and solutions for large-diameter butt welding The equipment tonnage required for material forming in Huanggang 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 a tee with large diameters and thick wall, this forming process is usually used. Ordinary lathe finishing, argon arc welding and other processing. The production standard of the high-voltage tee is the national standard and the American standard. High voltage tee is widely used in water conservancy power, food, beer and dairy industries and other processing and production. The hydraulic bulging of the high-pressure tee is a forming process that expands the branch pipe through the axial compensation of the metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and to extrude the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The pressure of the liquid increases as the volume of the tube blank becomes smaller. Alloy high-pressure tee is a pipe fitting that is often used for pipeline connection. It is mainly used in the main pipeline to branch. Large diameter butt welding tee generally has an equal diameter tee. Socket weld flange. Mechanical tee is divided into grooved mechanical tee and threaded mechanical tee. It can be used to directly connect branch pipes on steel pipes and has many applications in the installation of fire-fighting pipes and sprinkler pipes. Mechanical tee can be used when diversion or confluence is required. First, the steel pipe is opened with a hole punching machine, and then the mechanical tee is inserted into the hole, and the hole is sealed along the pipe wall by a sealing ring. Mechanical tee is divided into two types: wire connection and groove type. When the mechanical tee is connected, the clearance between the mechanical tee and the hole should be checked, all parts should be uniform, and then tightened in place; the distance between the mechanical tee openings should not be less than 1m.
