Polytex Tubo Verde, have the quality endorsement of the Institute of Materials and Structural Models, (IMME), of the Central University of Venezuela.
One more step towards the quality certification of our products in the Polytex Group's constant search for excellence is to guarantee the construction and plumbing market tubes and connections that exceed the most demanding quality standards.
“HECHO EN VENEZUELA CON CALIDAD TOTAL”
To guarantee our clients the quality and excellence of our polypropylene tubes and connections (PPR), at Famacoplas we signed an agreement with the Institute of Materials and Structural Models, (IMME), of the Central University of Venezuela to carry out laboratory tests that certify the expected quality standards of our products.
What is IMME?:
The IMME was born in 1949 with the fundamental mission of providing materials testing services for the industry and as a complement to the teaching and research activities of the UCV.
This center is a founding member and headquarters of the Ibero- American Association of Seismic Engineering (AIBIS) and the Venezuelan Society of Numerical Methods.
Its fundamental activities are divided into applied research tasks, teaching with emphasis on postgraduate studies, and advisory tasks and provision of services to the industry.
Currently, the IMME is one of the most advanced and complete sets of facilities in Latin America, with two buildings of more than 4,000 square meters, with a qualified group of researchers, technicians, and service, capable of operating in any scenario inside and outside of Venezuela.
Scope of the tests developed at the IMME with our tubes and connectors:
We started this ambitious project in October 2023, to certify the performance of our products in use tests in piping and connection systems. The areas of interest of this project have been the tests hydrostatic pressure, tests with water circulation at high temperatures and tube compression, and traction tests.
The polyfusion tubes and connections were chosen at random from our warehouse inventories. They were evaluated according to the scope of standards ISO15874 (Plastic piping system for hot and cold in-water installations) and DIN 8077 (Random polypropylene pipes).
Methodology:
Products from different batches with production certification by FAMACOPLAS and under the POLYTEX-TuboVerde brand were chosen.
In this first stage, the tests were carried out on products with diameters of 20mm and 110mm.
Hydrostatic pressure tests:
The use tests were carried out on 20mm and 110mm PN20 pipe, including the end cap, rings, elbows, and reductions to install the pressure gauges.
These tests certified the behavior of the system up to 560 psi for 110mm and over 400 psi for 20mm diameter pipes. Almost double the pressure of what must be guaranteed by standard and well above what would be a normal working pressure for any building.
Tests with water circulation at high temperatures:
Regarding temperature, the models were subjected to four temperature levels with water circulation to measure their degradation in hardness, yielding the following results:
- 20mm tube, the degradation was only 6% when it was subjected to water transfer at 100 degrees Celsius (boiling).
- 110mm tube in conditions similar to the previous ones, its properties only decreased by 4% of its hardness.
In tests at 50 degrees Celsius, a temperature higher than that of any residential water heater, the hardness remained 2% below its initial measurement.
These tests allowed us to conclude that our tubes and connections offer a level of safety well above the standard in their behavior when subjected to high temperatures.
Compression tests:
In this test, the tubes were subjected to loads in a hydraulic press, obtaining the following results when the piece began to deform:
The 20mm tubes withstood loads of up to 520 kilos before deforming.
While the 110mm tubes deformed without fractures from 17.05 tons, an amount equivalent to the weight of 15.5 medium-sized cars.
At Polytex we are committed to the quality and continuous improvement of our processes and products to provide the construction and plumbing market with the best option when choosing tubes and connections for the transfer of both cold and hot water.
