The tee joint is also known as a tee or tee joint. The main pipe adopts three-way joints. It has three vacancies, one for import and two for export; Or two inlets, one out. Is a chemical pipe fittings. It has T shape, Y shape, equal-diameter pipe hole and reduced-diameter tube hole. The utility model can be used to change the flow direction of a fluid and can also be used in pipes, pipes and pipes of various liquid chemical materials. Mainly used in medical, water conservancy (water-saving irrigation, water supply and drainage), energy (oil, natural gas, nuclear industry), construction and other engineering fields.
Three links classification:
1, classified by pipe diameter
Same diameter tee: main pipe and branch pipe
Three different diameters: branch diameter less than the main diameter.
2, classified by docking form
Butt welding tee: that is, after welding with the connection pipe fittings, the tee pipe fittings.
Socket tee: insert the connecting pipe into the two ends of the tee and weld the tee.
Clip sleeve tee: Each end is clip sleeve connector, insert connector, tighten tee connector.
Threaded tee: Pipe fitting with a threaded connection.
3, classified by material
Can be divided into stainless steel, carbon steel tee, copper tee, PVC tee, nodular cast iron tee.
4, classified by branch form
Main Tee: A tee fitting for a branch pipe vertical trunk.
Oblique tee: is the branch pipe and the main pipe into a certain angle of tee fittings.
Processing method of tee joint
Forging method
Use a forging press or an extension part that is part of the end of the punch and has a reduced outside diameter. Use forging press, connecting rod type and rolling type.
Two, stamping method
The use of a tapered core above the punch expands the tube end to the size and shape required in the market.
III. Drum method
The core is placed in the tube and the periphery is pushed by rollers to round the edge.
Four, rolling method
Generally, there is no mandrel and is suitable for thick-walled tubes with rounded edges.
Five, bending way
More commonly used are: stretch method, stamping method, roller method, there are 3-4 rollers, two fixed rollers, one adjusting roller, adjusting the pitch of the fixed roller, bending the finished tube.
Six, bulging law
There are two main methods: one is to put rubber into the tube and use a punch to compress it at the top to form a protruding part of the tube. The other is a hydraulic expansion, which fills the tube and the middle with liquid. The liquid ambient pressure causes the tube to bulge into the desired shape.
What is the difference between mechanical tee and reducer tee, and under what circumstances?
Mechanical tee refers to the method of processing tee. The diameter of the three refers to the three different caliber. In the quota, mechanical tee may include tee of all calibers.
Tees and reduced-diameter tees are connectors in pipelines. Tee generally refers to three nozzles of the same diameter (if they are one inch or two inches, etc.), The diameter of the three joints is not exactly the same (such as two of the two for two inches and one for one inch). The tee is used for the connection of the same diameter pipe, and the tee of different diameter pipe.
This is called a pipe joint. The main purpose of these parts is to connect the pipes together.
Four, is the same diameter of the pipe from four intersecting connection, the general shape of the four joints into a cross.
Tee, is formed by the intersection of three tubes with the same diameter. Generally, the angle between the three interfaces is 120 °.
The diameter of the four, there is no specific form of this, generally there are two equivalent strength of the relative interface, and the other two interface is equal to the previous two interface diameter, or smaller than the first two diameter.
Diameter three links, this is generally a live interface, the interface diameter is, the other two or equal to the main interface or less than.
The main difference between them is the diameter of the interface, the number of different angles. And they use the place is very wide, these names are only the general name of the class. In actual use, the size of its size, the form of connection, the production process is different, all determine their use direction. In terms of their general name, they are widely used in environmental protection, chemical industry, ventilation, material air delivery, thermal energy system, decoration and so on.
