The tee is a pipe fitting and a pipe connecting piece. Use in the main pipe to branch pipe.

Tee is the main conduit and branch pipe connection pipe fittings, according to the manufacturing material and use of the different, divided into many kinds, from the specification division, to be divided into the same diameter tee and reducer tee, the same diameter tee also known as equal diameter tee. Tee The same diameter tee is the same as the pipe diameter of the branch pipe and the pipe diameter of the supervisor; Reducer Tee is a branch of the pipe diameter is different from the pipe diameter, so also known as unequal diameter tee, the general diameter of the three-way tee.

The tee is mainly used for three identical or different intersection points of the pipeline is the collection of the place its main role is to change the direction of the fluid, this is the tee. Let's talk about the three-way tee. If it is connected in a manner that can be divided into two types of threaded and card-buckle connections

According to the shape we said above, Tee the T-shape and the Y-shape are the G-shaped, herringbone. In accordance with its material can be divided into metal and non-metallic materials of the metal material tee includes common alloy steel, stainless steel, carbon steel and so on non-metallic material tee like we know PVC, UPVC, PPR are belong to this kind of According to its structure, we can know: metal material tee It has such a pipe which is in charge and is connected to the supervisor and is arranged vertically with the supervisor. Tee A valve is set in the direction of the outlet and the direction of the branch exit (that is, where they intersect), and a circular valve is arranged on the valve. The valve plate is closed in the lumen of the tube cavity with the inner wall of the structure of mutual sealing. Such a new design simplifies the pipeline setup, but also saves the pipe parts and components, Tee thus facilitates the operation of the staff master, also facilitates the pipeline shunt maintenance and the various branches of the stage supply. Some of the design in addition to the role of traditional tee, but also play the role of dual-station valve, that is, the supervisor and the branch output can be arbitrarily selected one is closed, the other is unblocked working state; This can also arbitrarily adjust the Supervisor and branch output of the flow ratio, Tee as long as the control valve in the lumen of the angle can be, Isn't it convenient? When I was talking to someone, my interested friend asked me how this thing was made, what is the use of our life? In fact, his processing and production is not very difficult, two kinds of shapes are generally used to draw a picture of the first CAD paper and then use mechanical production here to compare the complex point, The tee, which is first stamped and then cut and polished, is mainly used to change the direction of the fluid, which can be used for water pipelines,

Pipeline and all kinds of liquid chemical material conveying pipeline

It can also be used for water conservation and drainage, there are three on the dam, Tee as well as energy sources such as natural gas, nuclear industry, oil and construction and other fields

Divided by process

1. Hydraulic bulge shape

The hydraulic bulging of tee is a kind of forming process which is compensated by the axial compensation of the metal material. The process is to use a special hydraulic machine, Tee will be equal to the tee diameter of the tube injected into the liquid, by synchronizing the two horizontal cylinders of the hydraulic press with the medium motion extruded tube Billet, the volume becomes smaller after extrusion, and the liquid in the Tube billet increases with the volume of the tube, and when the pressure of the tee branch tube expands, Metal material in the side cylinder and tube billet under the dual action of the liquid pressure in the mold cavity flow and swell out of the branch tube.

The hydraulic bulging process of tee can be formed at one time, Tee the production efficiency is higher, and the head and shoulder wall thickness of tee are increased.

2. Hot pressing forming

The three-tee hot-pressing forming is a tube billet larger than the tee diameter, flattening about the diameter of the tee, the cold drawing tee opens a hole in the part of the tensile branch pipe, the tube billet is heated, put into the forming die, and the die of the tensile branch tube is loaded in the Tube billet. Tee The billet is radially compressed under the action of the pressure, In the process of radial compression, the metal flows in the direction of the branch pipe and forms a branch tube under the tensile force of the die. The whole process is formed by the radial compression of the tube billet and the stretching process of the branch pipe part. Unlike the hydraulic bulge tee, the metal of the hot-pressing TEE branch is compensated by the radial movement of the tube billet, so it is also called the radial compensation process.

3. Splicing forming

The use of short tube welding (or bonding) forming, saving materials, reduce costs. Tee But we need to ensure the reliability of welding (or bonding) process, if necessary, to do the appropriate seam inspection: such as pressure test, flaw detection, magnetic powder.

4. Forging forming

Because of the limitation of equipment and processing conditions, Tee the forging tee is generally small-caliber. The processing cost is relatively high.
