Quality Assurance

Always aiming at ensuring top quality, Interplast production lines, apart from the usual mechanical equipment used to produce Polyethylene pipes, are supplied with the following additional equipment assuring an absolute degree of quality and ensuring that the consumer receives integrated systems of the highest quality.

In this way the intake of the Extruder is stabilized for raw materials that easily absorb humidity, thus eliminating the problem of altered dimensions which is quite a frequent phenomenon in several pipes of the competition.

Thus we achieve steady weight per meter in the manufactured pipe, which renders the maintenance of steady dimensions necessary. This is the first part of checking the pipe’s dimensions.

A system where the desired limits of the pipe’s wall thickness are automatically regulated by means of the extruder. This is the second part of ensuring and observing the pipe’s dimensions and results in a proper fit of the nozzle of the brass fitting to the pipe.

This is the third and final part of electronic testing. The accurate measurements of the LASER SCANNER ensure proper fitting of the nut to the plastic pipe.

Alongside all this, guarantee the production of high quality pipes directed to water and heating, and are the following:

Its special design for the production of Polyethylene pipes in combination with the top quality of the raw materials ensures that the pipe material has homogenized perfectly. This way we achieve its high mechanical strengths and a long lifespan.

In this way we guarantee proper fit between components of our own manufacture.

The outer diameter is checked by means of a strap gauge, wall thickness and oval of pipe by means of an electronic thickness gauge.

The measurements are entered daily in the ISO reports after the end of the laboratory testing. After the results are evaluated the order is given for distribution.
