In the construction of pipeline networks, there is a constant need for cutting pipes, which requires compliance with several recommendations and rules in the process of work or when using the equipment. Naturally, it is not recommended to use tools such as a grinder, a hacksaw, or a saw to cut pipes.
Their use, as a rule, leads to the accumulation of metal rash, which negatively affects the quality and properties of some types of pipes. A pipe cutter for metal pipes, as well as for cutting steel and plastic products, is selected both depending on the material and purpose. That is, we can say that different tools are used for different types. In the article, we will consider the main types and characteristics of pipe cutters.
Pipe cutters classification
The type of pipe cutter is determined by the materials of the pipes intended for cutting. Of course, there is equipment on the market that have more versatile functions and is designed to process all types of pipes. For example, to cut copper, you can use a roller pipe cutter, usually used for steel pipes. They can also cut metal-plastic pipelines.
The principle of operation of pipe cutters
Pipe cutters on the market are presented in several versions: manual pipe cutters, and electric pipe cutters. At work, it is possible to use a pneumatic drive or a hydraulic drive, which allows you to cut durable concrete products, ceramics, steel, and cast iron. Manual models have a simpler design, which is quite affordable and does not require special training. You can even use them at home. The principle of their operation is based on the rotation of the handle, through which the pipe is cut.
An electric pipe cutting machine is best used when there is a large amount of work. Thanks to this type of device, the application of physical effort are not required, and the efficiency is significantly increased. However, the cost of electric pipe cutters is much higher.
Pipe wall thickness
It is necessary to choose a pipe cutter model based on the characteristics of the pipe itself. This applies to both the material from which it is made and the thickness of the walls. Depending on the wall thickness, the following tool models are selected:
- Thin-walled pipes – rotary pipe cutter of roller or cutter type.
- Thick-walled pipes – multi-roller, clamp, or chain pipe cutters.
- Ceramic or concrete pipes – chain pipe cutter.
Types of pipe cutters by drive type
Pipe cutters are used in various industries and households, so they may have a different type of drive. These elements are of 4 types:
Manual pipe cutters cut the pipe due to the physical effort of the worker. They are designed for home use. Lightweight and quiet operation.
- Easy to use.
- Are inexpensive.
- Ideal for small jobs.
- Cutting a pipe requires a lot of physical force.
- Not suitable for cutting a large number of pipes.
Electric models are the most productive. Their dimensions and weight depend on the power of the electric motor used in them and the pipe-fixing mechanism. Can be used permanently or in the field. Pipes are cut by a rotating disk. They have additional fasteners that allow you to make an even cut. There is also cordless models ideal for field work where many pipes need to be cut.
A pipe cutter for steel pipes with an electric drive can be of the following types:
- One-piece. Mainly used in everyday life.
- Detachable. Allows you to cut pipes, make chamfers and perform trimming. The body of these pipe cutters is divided into two parts, so they can be installed on pipelines under repair to perform the necessary work.
- The most productive
- Cut pipes without burrs
- Allow you to make a chamfer for the subsequent welding of products together
- The operation of this equipment requires a stable power supply of 220 or 380 V, however, there are battery models
- Work noisily
- Are more expensive than manual ones
Pipe cutters of this type work on the same principle as manual ones, but they are compressed due to the pressure of compressed air. It acts on the clamping mechanism that tightly compresses the pipes. This equipment requires a powerful compressor with an air receiver.
- Tightly compress pipes.
- Cut pipes without burrs.
- Allow you to make a chamfer for welding.
- Cut pipes of any diameter with any wall thickness.
- Compressor noise during operation.
- Compressor maintenance.
These models cut pipes due to fluid pressure, so a powerful electric or manual hydraulic pump is required for operation. Equipment of this type is more powerful and productive than manual pipe cutters but in all respects worse than electric saw models.
They are very heavy, so many of them are installed permanently. A feature of the hydraulic tool in the drive, thanks to which it is possible to cut pipes in a limited space and even underwater, is important for laying pipelines for various purposes underground and underwater.
- Make a straight cut.
- Does not require electricity to work.
- Work quietly.
- Can cut pipes in confined spaces and underwater.
This is the additional maintenance of the hydraulic pump.
Make sure that when you are choosing the pipe cutters, you understand what you are looking for. Because if your requirements are not clear then you will face issues while buying. So, understand and purchase accordingly.
