Today, polyethylene pipes are used almost everywhere. The fact is that they have very good characteristics. However, the equipment for the production of polyethylene pipes must be properly selected and work efficiently.
Material advantages
It should be noted that such products have a large number of advantages:
- high resistance to negative influences (these elements can be used in the construction of water supply networks, gas systems and other structures; such pipes are resistant to temperature extremes, corrosion and rust);
- durability (the material presented is able to serve more than 50 years, therefore it is more effective than metal elements);
- good ductility and strength;
- simplicity of operation and laying;
- do not require additional insulation;
- light weight, which is a significant advantage for transportation and use of elements.
What is the material made of?
In order to determine what equipment is required for the production of polyethylene pipes, you first need to understand what raw material this material can be made from. In principle, there is nothing complicated here. For production, polyethylene granules are used. In order to get a homogeneous mass, it must be boiled in a special machine called an “extruder”.
Naturally, in order for the pipe to have certain characteristics, various plasticizers and other additives are added to the mass during manufacture. Thanks to them, the product can be more resistant to frost, the influence of water and other negative phenomena. And additives can change the density of polyethylene pipes.
What equipment is necessary for work?
In order to produce the presented material, you need a machine for the production of polyethylene pipes, and not one. So, you will need:
- a device with which the granules will be continuously fed into the hopper of the extruder;
- apparatus in which plasticization of raw materials and its enrichment with various additives is carried out;
- a vacuum apparatus that calibrates the workpiece;
- cooling baths;
- the mechanism by which the workpiece moves along the production line;
- cutting apparatus;
- device for ultrasonic accuracy control of finished elements;
- Remote Control.
In principle, the line for the production of polyethylene pipes does not require any other mechanisms.
Material manufacturing technology
As practice shows, it is not difficult to make the presented element. The whole process begins with the acquisition of raw materials. After the pellets are already in production, they are fed into the hopper of the extruder. Here, under the influence of high temperature, the granules melt and turn into a homogeneous mass, which can be enriched with the necessary additives.
All this mixture passes through the forming head under high pressure. Then it gets into the cooling device, in which it is calibrated to a given diameter. All this is done in a vacuum environment. This process is very important for the quality and type of material obtained.
Next, the pipe is cut into parts of a given length using a planetary saw. Naturally, it should be very high quality, because no burrs should remain on the edges of the product.After that, the material passes the necessary marking and is folded into bays of 100-200 meters or less, depending on the diameter of the pipe.
The entire production process is controlled by the operator using an automatic control panel.
Features of the choice of equipment
Naturally, in order for the procedure to occur without problems, it is necessary to correctly purchase equipment. So, it must be, above all, quality. That is, at the time of purchase, you must give preference to already known manufacturers.
Particular attention should be paid to the extruder for the production of polyethylene pipes and a cooling device. If at the moment it is not possible to purchase new equipment, you can use the equipment that was in use. However, you should buy it very carefully.
Next, you should pay attention to the performance of the line, as well as the functionality of the calibrating mechanism. The fact is that the higher these indicators, the more pipes of different sizes can be produced per day. Naturally, the total profit depends on this.
After installing all the machines, it is necessary to consult with staff regarding the rules of conduct near the production line. The fact is that if the safety rules are not followed, the employee can be seriously injured.
In principle, these are all the features of the configuration and selection of the necessary equipment.
