Production of plastic pipes
The market for the production of plastic pipes in Russia today is very scale. This is primarily due to the relatively simple method of production, and secondly with the growing demand for this type of product. Application of plastic pipes is very wide: it and sewerage infrastructure, heating system, and conduct gas and water. Also plastic pipes are used in the creation of a floor heating.
The breadth of the application of this product is due to their material production. Thus, the plastic is durable, corrosion resistant, easily withstand temperatures up to 200 degrees, does not oxidize water pipes are not themselves exposed to limescale, use a period of up to 50 years of work, plus they are lighter and easier to strip, as Maintain a good strain.
Existing market manufacturers are constantly improve production technology, thereby expanding the range of products. I must say that now there is a fairly high level of competition among manufacturers. Therefore, if you stay at this business should be from the first moments of activity to produce the highest quality product at the most reasonable price for the consumer.
Technology of production of plastic pipes
The raw material for the production of pipes are polymers of high pressure, as well as in some cases the polymers are low-pressure, polybutene, polypropylene, polyvinyl chloride is also used et al. Production of pipes - is the most environmentally friendly process. It happens all the extrusion, in other words, the pipe, in the literal sense of the word, squeezed out of the softened plastic through specialized equipment, called an extruder. Now manufacturers of machines for the production of pipes supplying some of their species.
It:
- Screw - basically like a meat grinder or juicer;
- Besshnekovye - where the foundation for the production of pipes carries the disk of the equipment. It is usually used when the tubes are made from composite materials;
- Combinatorial - combines the performance of the auger and besshnekovogo, ie disk.
Special distribution have screw extruders. They in turn are divided into High-low single-stage and on specialized and universal, as well as on single or twin screw. You can select a separate group extruders equipped with degassing and heat chamber devoid of it. This is only a small part of the varieties of machine tools for the production of plastic pipes.
Manufacturers each year improve their machines, supplementing them with new features and enhancements. So list the complete list with the entire set of characteristics is quite difficult.
In general plastic pipe manufacturing process can be described as follows. The granulated feedstock is placed in a special hopper of an extruder, where as a result of high temperature liquefied plastic. Then the plastic mass is extruded through a forming head which defines the basic characteristics of the future tube. The next step in the resulting preform stretch towing vehicle, where it is the primary cooling and under high pressure, it becomes a ready form. At the last stage, the cutting and twisting pipes in the bay, or their stacking.
Raw materials for production
Industrial production line of plastic pipes in addition to the basic equipment of the extruder, has available a machine for cutting, as a system of feed, bath for cooling and calibration, high-mixer, pulling device, a vacuum machine molding and Receiver Drive producing pipe-laying in piles.
As a rule, the performance of the enterprise for the production of pipes is determined by the size of the products. Thus, when the pipe diameter 20-25 produced an average of 80 kg per hour tube, when the tube diameter of 32 to 50 - 100 kg per hour, with a diameter in excess of 63 - 130 kg per hour. Over time, one production line pipe allows you to get about 1 km of plastic pipes. Each line is quite unique and allows the manufacturer to make an order for equipment that is focused on your business. The minimum cost of a production line starts with 400 thousand. Rubles.
Speaking of raw materials, it should be noted that at the time of purchase is necessary to monitor its quality and shelf life. In this context, polypropylene and polyethylene are also a good choice of material because They have absolutely unlimited shelf life. The best raw material is considered to be a copolymer of polypropylene and its market value varies from 50 to 70 rubles per 1 kg of pellets.
Widespread use of a low-pressure polyethylene, and, first of all it is due to its low cost - 40 rubles per kg. A good practice to purchase raw materials from one plant, it can reduce the cost and time for the conversion and migration tools, as well as producing the same quality of the pipe. Thus, a polyethylene plant may be different from other polyethylene effect differing production technologies.
Recommendations regarding the selection of staff and premises
The room, which will be made of plastic tubes must have the following set of characteristics: to be a good approach to the storerooms, respectively, the warehouse itself, the shop with an area of not less than 40 square meters. m. (optimally up to 200 square meters), as room must be equipped with a bathroom and located in the industrial zone of the city.
To serve one production line on average, need no more than 3 people. The same should be hired equipment operators, technicians and laborers. The level of wages for employees You are free to establish themselves, but keep in mind that good technology is not going to work for wages below 50 thousand. Rubles.
Demands
Start of production is associated with large paperwork. You will need to get permission from the fire inspection, service gas, sanitary and epidemiological station, Gosnadzorohrantruda from local authorities and others. In our country, this is probably one of the most difficult stages. It is very important, bumping into obstacles of bureaucracy, do not give up.
In accordance with GOST 18599-2001, the following conditions of storage and transportation of plastic pipes. In accordance with the products authorized to carry absolutely any kind of transport in covered freight wagons or the car body. Also the pipes must be protected from dust and various external effects, they must be sealed with a plug, and properly packaged.
The volume and weight of the wound into a coil pipes must not exceed 1.25 tons, the length of the stacking tubes should not be more than 5.5 meters.
When storing pipes in stock, they should be protected from direct sunlight, high temperatures and in a horizontal position. When storing pipes more than 2 months, the height of the stack should not be more than 2 meters. When storing pipes less than 2 months the height can reach up to 2 meters. The total duration of storage of the pipes should not exceed 12 months, a minimum shelf life of the pipe, according to the law, can not be less than 2 years from the date of manufacture.
Sale of goods
Start of production can start themselves with a minimum of 8-9 million rubles. And it provided, that will not be purchased new and used equipment and the volume of 100 tons of raw materials. Plus, in this start-up capital has just laid the salary for the first six months of work and room rental for the same period. For sufficiently large investments this business has a high degree of return. So, you go on the net profit after a maximum of 2 years. On average, these manufacturers are paying off equipment for 1.5 years.
Speaking of profitability can be argued that today, because of the high level of competition, it is not stable and has spread from 2 to 20%.
The final price for the goods is enough biodiversity and to a greater extent depends on the characteristics of the pipe. For example, a pipe having a diameter of 63 mm on average costs about 90 rubles per pog.m. and pipe diameter of 800 mm on the market sold for 14 thousand. Rubles. With the implementation of the product must be guided by the original area of application of plastic pipes. They were described above. It would be good to establish contacts with regional firms making the installation of pipes, they will provide you with regular orders for their needs. Plus, do not pass by the large and small household hardware store.
