The extrusion vacuum tank plays an important role in the pipe production process and is a critical piece of equipment that increases quality, efficiency, and precision in pipe production. In pipe production, especially during the production of plastic pipes, the function of the vacuum tank can be summarized as follows:

1. Pipe Shaping and Cooling:
Following the extrusion process, the hot and soft plastic pipes are placed in the vacuum tank. The vacuum tank assumes an important cooling and shaping function to ensure that the pipes reach the desired shape and size.

Shape Control: As plastic pipes are continuously drawn and shaped during extrusion, the vacuum tank helps the pipe take a smoother shape thanks to the vacuum it applies to the outer surface of the pipe. This process helps the pipe to have a uniform diameter and ensures that the wall thickness is homogeneous.

Cooling: The plastic pipe is rapidly cooled inside the vacuum tank. During cooling, the inner part of the pipe cools faster than the outer part, which ensures that the shape of the pipe is preserved. This cooling process also affects the final hardness and durability of the pipe.

2. Size and Diameter Control:
The vacuum tank guarantees high quality by keeping the diameter and length of the pipe within a certain tolerance range. Thanks to the vacuum applied to the outer surface of the pipe, the diameter of the pipe is precisely controlled and it is ensured that it is produced in the desired dimensions.

3. Drawing and Extension:
As the length of the pipe increases during extrusion, the vacuum tank draws the pipe at an appropriate speed. The elongation of the pipe provides a control mechanism that prevents shape distortions. This mechanism ensures that the pipe is drawn at a constant speed and cools down evenly.

4. Production Speed and Efficiency:
The vacuum tank increases the pipe production speed. Since the cooling process takes place quickly, the pipes are shaped in a shorter time and can be processed as final products. This increases efficiency in the production process and shortens the total production time.

5. Structural Features of the Vacuum Tank:
Vacuum tanks are usually made of durable materials such as stainless steel and are in constant contact with liquid. The tank contains water and the temperature of the water is usually controlled, which provides more precise cooling. The vacuum pump ensures that a uniform vacuum is applied to the outer surface of the pipes, thereby achieving a smooth shape.

In summary:
The extrusion vacuum tank is an indispensable part of the pipe production process. It plays an important role in shaping, cooling, and controlling the dimensions of pipes. This equipment increases production speed while maintaining high quality and helps to reduce costs.
