Introduction to the types of vacuum pipe fittings

1. Introduction to the three links.

Three-way pipe fittings are a kind of pipeline connectors. They are used at the branch pipes of the main pipeline. There are equal diameters and different diameters.

2. Classification.

Sorted by diameter:

Same diameter tee: a tee with the same diameter as the branch pipe.

Reducing tee : the case where the diameter of the branch pipe is smaller than the diameter of the main pipe. Reducing tee, "reducing tee" is a professional term, mainly refers to the pipe fittings and pipe joints used in the branch part of the pipe, and the reducing tee is one of them. There are two types of T: ordinary equal diameter tee and reducing tee. Because all three terminals can be connected to the pipeline.

The processing method of the three-way joint is to mark the position and punch holes on the pipe fittings. Install ejector devices on the pipeline, including metal rods, propellers, rectifiers, brackets, etc. When the metal rod is heated, use a jack and a metal rod to push in, push the metal rod and the pipe wall in, and then pour it out naturally to form a reducing tee. Weld the pipe section of the corresponding specification on the reducing tee formed by spraying to produce the product. The reducing tee has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and the scope of application is from high vacuum valves to high pressure valves. Rotate 90 degrees, and the water inlet and outlet positions should be spherical to prevent movement. The three-way ball valve is a new type of ball valve. It has special advantages in structure, such as frictionless switch and wear-free opening and closing torque.

Classified by docking method:

Butt-welding tee: the tee-welding is carried out after butt jointing with the pipe fittings.

Socket tee: It is a tee pipe fitting that is welded or welded after inserting the connecting pipe into each end of the tee.

Jacketed tee: that is, a three-way pipe fitting where each end is a jacket joint, and the pipe fitting is inserted and then fastened.

Spiral three-way pipe: a three-way pipe component that connects pipe fittings with threads.

By material category:

It can be divided into stainless steel tees, carbon steel tees, copper tees, pvc tees, ductile iron tees, etc.

Classified by support form:

Positive tee: the tee joint of the branch pipe and the vertical main pipe.

Oblique three-way: the three-way piece with some angles between the branch pipe and the monitor.

3. Scope of application.

Three-way pipe fittings are used where the pipeline has branches. Because of its simple and convenient use, it is widely used in the chemical industry, civil construction, machinery manufacturing, shipbuilding industry and other industries.
