The production of HDPE pipes today is becoming increasingly popular among businessmen. This is due to the fact that these pipes have many advantages over their competitors.
That is why in construction markets they are in great demand. Engaged in their production today is very profitable. There are various equipment for the production of HDPE pipes. Everyone can choose the machines or lines he needs for mass production, but we will talk about that again. First, let's look at the question of what HDPE pipes are.
What is an HDPE pipe?
To begin with, it is made exclusively from low-pressure polyethylene, which has a fairly high density. There are two main types of HDPE pipes:
- Gas - intended for underground gasification, such pipes in accordance with GOST are produced with a yellow strip.
- Plumbing - designed for plumbing and sewage, according to GOST they are available with a blue stripe.
Their main advantages are durability and unpretentiousness to the environment in which they will be placed. They have very low thermal conductivity, are resistant to various chemical environments. They are not afraid of corrosion, they are quite flexible and most importantly they are environmentally friendly. Installation of such pipes is very easy. When carrying out work, complex and heavy equipment is not required. The pipes must be stored in a horizontal position, avoiding any mechanical damage.
HDPE pipe production technology
The technology for the production of HDPE pipes is quite simple. The material from which the pipe is made is heated to an elastic, almost liquid state and pushed through a special form. Due to the high pressure in the form of a die, the walls of the pipes are quite dense, without bubbles and thin spots.
A die is defined as a certain shape that determines the final dimensions and type of pipe, as well as its quality. For high-quality production in the die it is necessary to maintain a fixed temperature. Passing through it, the pipe forms and cools. At the penultimate stage, it goes through a series of clamps that prevent it from deforming.
After complete cooling, the pipe is cut or laid in coils. For cutting use special guillotines.
Equipment for the production of HDPE pipes
At various stages of pipe manufacturing, different types of equipment are used. These types include:
1) Extruders - designed to soften and mix the material.
2) Die - a special form for molding the product.
3) Guillotine - a special tool that simplifies the cutting of finished products.
Equipment for the production of HDPE pipes can be divided into three main types:
- screw machines;
- disk machines;
- combined machines.
The first type of machine or tape for pipe production, works on the principle of the Archimedes screw, passing through which the material is heated and pushed into the die.
The second type is disk. The basic principle of operation is that discs move raw materials by adhesion. The main advantage of this type of equipment is the high-quality mixing of the material - low-pressure plastic.
The combined machine for the production of HDPE pipes is a complex complex that includes the two previous machines, or rather, their production technology. The disks thoroughly mix all the material, and the screw pushes it into the mold.
In addition to certain types of machines and additional equipment, there is such a thing as a line for the production of HDPE pipes. This complex is designed for fast and continuous production.
Pipe scope
Such pipes are quite widespread in the field of drinking water and process water. A secondary area of application is the laying of sewers, watercourses, etc. In addition, there is another type of pipe used in the field of power supply. They serve as protection against damage to electrical cables. They are also used for gas pipelines. Pipes must be used clearly for their intended purpose.
I ask for your recommendations and indicative prices for equipment for such a production. Thank you in advance.
