The manufacturing process of plastic pipes

Equipment for the production of pipes of plastic

Continued growth in production is due to the increasing demand for plastic pipes due to their valuable performance characteristics:

• they are resistant to corrosion, have high chemical resistance and ability to withstand harsh environments;
• pipes have a long service life;
• not need cathodic protection;
• not debug the fat accumulation, so the diameter of the pipe is not narrowed;
• using plastic pipes reduces heat losses due to the low thermal conductivity;
• probability of failure of plastic pipes during freezing inside the liquid is lower than that of counterparts from metal;
• lightweight products make installation less time consuming.

raw material for the production of plastic pipes may be polybutylene, polyvinyl chloride, polypropylene, polymeric materials, and even recycled - plastic bottles or film waste, disposable tableware, the body of techniques and equipment, and other debris.

equipment is quite simple and not numerous.The basis of the whole production - extruder.This is a special machine for the manufacture of plastic pipes.The whole process of machine operation is extruded (extruded) pipe from the hot plastic granulate.Extruders are:

1. Screw.action principle of the method is similar to a meat grinder, and the most common.
2. Bezshnekovye disk.
3. combined simultaneously with disk and screw.

production line has a continuous closed loop.In the hopper of the extruder is filled with polymer granules, where they are melted using a heater ring.The screw creates a rotary motion, whereby molten plastic enters the extrusion head, and there is a high-pressure pipe is shaping the future.The machine has a vacuum calibration zone where the formation of diameter and wall thickness as well as the primary cooling of the product.

Gradually, the pipe passes into another cooling chamber until until completely cool.Promotion provided by a special pipe pulling device with caterpillars.During the pulling device is a cutting device which forms a predetermined length.On request, tubes can be wound into coils or available dimensional segments.The entire production is monitored and coordinated PLC which monitors the uninterrupted and quality production.

How is quality control, transportation and storage

finished tube should be checked for compliance with the following parameters:

• outer diameter;
• wall thickness;
• dimensional length of the segments;
• roundness.

control is carried out in laboratories by checking selected control samples from production batch.If the product meets all the standard indicators, the technician will issue a document on the line quality.After that the products supplied to the shops or delivered to the customer.

is stored finished product must be in an upright position away from heating appliances and hidden from the sunlight.Transporting plastic pipes can be any means of transport, but in the covered body.Bay or dimensional segments to be packaged and the ends of the pipe plugs protect from falling debris.

simplicity of the process of production of plastic pipes, cheap raw materials, low labor input allow people even do not have a large start-up capital, to open your own profitable business.
