Always aiming to ensure absolute quality, Interplast's production lines, in addition to the usual mechanical equipment with which the Polypropylene Drainage (PP-H) pipes are produced, are equipped with the following additional equipment, ensuring the quality to an absolute degree and bringing to the consumer the certainty that he has at his disposal perfect systems of high quality.
The raw materials, although available from the suppliers in airtight packaging, have the property of absorbing moisture. By dehumidifying them immediately before production, stabilization of the data of the extrusion machine is achieved and phenomena of deviations of the pipe dimensions from the nominal ones are avoided.
The special arrangement of magnets in the power supplies of the extrusion machines ensures protection against ferromagnetic foreign matter.
With the specific automation of the adjustment of the turns of the extrusion screw, a constant weight per meter of pipe produced and therefore pipe dimensions with no deviations from the nominal ones are achieved. It is the first part of ensuring the correct dimensions.
It is an automation of the system in which the desired dimension of the pipe wall thickness is set and automatic corrections are achieved through the pulling mechanism of the production line. It is the second part of ensuring the correct dimensions of the pipes.
It is the third part of ensuring the correct diameter of the pipes. As a result, productions with absolutely constant cross-sectional dimensions, which are expressed in perfect connection applications and smooth runoff flows.
Along with the use of the above equipment to ensure the correct geometry of the pipes, Interplast applies the following also critical elements to additionally ensure the high specifications of the pipes.
Its special design for the production of polypropylene pipes and drainage fittings combined with the high quality of raw materials ensures that the pipe material is perfectly homogenized. In this way, its high mechanical strength and its practically unlimited lifetime are achieved.
These are plug-in tests at regular intervals by production managers.
The outer diameter, wall thickness and ovality of the tubes are constantly checked with calibrated instruments to avoid any possible failure. The measured samples are re-checked even after the successful results of the laboratory quality checks have been completed in accordance with the specifications of the relevant standards and the order to dispose of the products is given.
