Three kinds of belling machines are most popular, which are belling machines for PVC pipes, socketing machines for HDPE pipes, and belling machines for PP pipes.

Figure 1 Automatic Belling Machine

Figure 1: Automatic Belling Machine

Polyvinyl Chloride (PVC) pipes are widely used in irrigation, plumbing, and various other industrial applications. Typically, the solvent cement method is employed by belling machines for PVC pipes. These machines consist of various sizes to accommodate various socket configurations and pipe diameters.

In terms of socket configurations, there are three types, which are Plain Type (U-type), Rubber Ring type (R-type), and Rectangle Type.

U-type socket configuration is generally used for sewage and conduit pipes, whereas R-type is used for those pipes, which usually cater to the supply of water. Solvent glue is used to connect U-type socket pipes, whereas a spigot-type gasket is used to connect R-type and rectangle-type socketing pipes.

For PVC pipes, the U and R types of sockets are widely used.

Polyethylene (PE) pipes are commonly used for the distribution of gas, irrigation, and water supply systems. Typically, expanding belling method is utilized by belling machines for PE pipes.

In terms of socket configurations, these pipes usually deploy U-type sockets. However, PE socketing machine is a rare sight to see.

Polypropylene (PP) pipes are the kinds of pipes that are commonly used in wastewater treatment and chemical processing. These pipes are widely known for their remarkable chemical resistance.

In terms of socket configurations, PP pipes usually deploy rectangle types.

Belling machines for PP pipes can utilize either expanding belling technique or a solvent cement technique, depending on the requirements.

2.Are belling machines suitable for different types and sizes of pipes?

Yes, belling machines are designed in such a way as to accommodate different types and sizes of pipes. Given industrial applications, belling machines are manufactured to cater to the diverse needs of the industry.

Belling machines can work on multiple plastic pipes, by altering the belling mold. The diameters of these pipes can be 20-110mm, 50-250mm, and 400-800mm.

In addition to these measurements, WeCoEx is the kind of belling machine manufacturer that can provide such belling machines that can cater to a wide range of pipe sizes and diameters.

Keeping in view the diameter of the pipe and its wall thickness, the socketing mold is created.

Figure 2 Belling Machine for Different Pipe Sizes

Figure 2: Belling Machine for Different Pipe Sizes

That is why belling machines can steer a wide range of pipe materials, wall thicknesses, and pipe diameters. So, if you want a certain type and size of your PVC, PE, or PP pipe, belling machines can handle it.

Because of WeCoEx customization options, all you have to do is send us your specifications, and the rest will be taken care of.

3.What is the working principle of belling machines for PVC, HDPE, and PP pipes? 

The working principles of belling machines for PVC, HDPE, and PP pipes can vary depending on the material being used and the particular type of belling machine. The working principle of each type of belling machine is explored below.

Working principle of belling machine for PVC pipes:

A solvent cement method is generally employed in belling machines for PVC pipes. The working principle of PVC pipes starts with the heating process. The end of the pipe is heated using hot air or a heated element to soften the PVC material.

Once the end of the pipe is heated to the perfect temperature, solvent cement is added to the socket area. The softened PVC material and the solvent cement fuse, which creates a strong bond between the belling mold and the pipe end.

The cemented pipe end is then inserted into the belling mold, which has the desired shape of the socket. Once the pipe has been cooled down and the solvent cement has been set, the socket joint gets secured firmly.

Working Principle of Belling Machines for HDPE Pipes:

An expanding belling method is generally employed in belling machines for HDPE pipes. The working principle of PVC pipes starts with the heating and clamping process. Using hot air or a heating element, the pipe end is heated, and the HDPE pipe gets clamped securely.

The hot air or heating material softens the HDPE pipe, which is then expanded using a hydraulic or mechanical mechanism. The softened HDPE material is pushed outward by the expanding head of the machine, forming the bell shape.

Once the expansion is complete, the pipe is then given some time to cool down and solidify. A smooth socket is then formed, which can be easily jointed with other fittings or pipes.

Working Principle of Belling Machines for PP Pipes:

Belling machines for PP pipes can either use the expanding belling method similar to HDPE pipes or the solvent cement method similar to PVC pipes. No matter which process is deployed, the working principle remains the same as mentioned above.

However, it is essential to note that some belling machines may include automation options and additional features to elevate accuracy and efficiency. Some machines may include touchscreen interfaces, PLC controls, and multiple other belling tooling options to cater to varying sizes of pipes and sockets.

4.How to choose the right belling machine as per your requirements?

Choosing the right belling machine as per your requirements can be an intricate process. However, the process can be made easier, if you consider these factors.

Figure 3 Customized Belling Machine

Figure 3: Customized Belling Machine

The first thing you need to cater to is to determine the specifications of the pipe you will be belling (PVC, HDPE, and PP), their wall thickness, and their diameters. As mentioned earlier, belling machines can mold a wide range of pipes, which have diameters of 20-110mm, 50-250mm, and 400-800mm.

Understanding the specifications of your pipe can help narrow down your options for belling machines.

The next thing you will need to consider is to look for a belling machine manufacturer that offers flexibility and customization options.

If you need someone to accommodate different pipe sizes, production variations, and socket configurations, it is better if your belling machine manufacturer offers customizations.

10.What are the two methods of cooling used in belling machines, and how do they differ in terms of efficiency and effectiveness? 

Belling machines usually employ two kinds of cooling methods, which are air cooling and water cooling. Both methods are utilized to solidify the formed sockets.

Let’s see how both of these methods differ in terms of efficiency and effectiveness.

Air cooling method: As the name indicates, in the air cooling method, ambient air is used to solidify the pipe socket by cooling down the belling area.

When the heated pipe end is entered into the belling mold and the socket is created, the surrounding air is used to cool down the pipe naturally.

Efficiency and Effectiveness:

Efficiency: In terms of energy consumption, this method seems to be relatively efficient because it relies on the air’s cooling properties.

No additional resources such as cooling systems or water pumps are required for the cooling process, which results in cost savings.

Effectiveness: The effectiveness of air cooling generally depends on the temperature and the circulation of air around the area of the belling mold.

In warmer situations or environments, poor circulation of air can stretch out the time needed for the cooling process to get completed, slowing the entire production process.

Water Cooling method:

In the case of the water cooling method, a water cooling system is deployed into the belling machine to facilitate more controlled and faster cooling. Your belling machine manufacturer may include water channels or sprayers as water cooling systems.

Figure 7 Highly Optimized Belling Machine

Figure 6: Belling Machines having Water Cooling Mechanism

Efficiency and Effectiveness:

Efficiency: Compared to the air cooling method, the water cooling method seems to be much more efficient because of its cooling speed.

A quicker cooling process can be employed because of the controlled flow of water.

Effectiveness: For rapid solidification of the pipe socket, the water cooling method is considered to be much more effective.

Consistent cooling is maintained through the controlled application of cool water, which reduces the chances of improper formation of the socket due to overheating.


Air cooling is much more energy-efficient than the water cooling mechanism because it works on natural convection, whereas the water cooling method involves water circulation through the use of water channels or sprayers.

However, to produce larger pipe sizes or in high-speed production lines, the water cooling method is usually preferred over the air cooling method to prevent deformation and maintain consistent quality.

11.What technical support and after-sales services are provided by belling machine manufacturers?

Different belling machine manufacturers provide different kinds of technical support and after-sales services.
