HIGH CHEMICAL RESITANCE

HDPE high-density polyethylene is one of the most resistant materials to the majority of chemical compounds that appear in pipes, including H2SO4, HCL, HNO3, H3PO4, SH2, which is the most dangerous element in sewer pipes.
Due to this, HDPE Spiral pipes guarantee their durability without the need for internal and / or external coatings and without any restriction on the magnitude of deformations in the pipe, since, on the one hand, the The material does not crack and, on the other hand, is completely homogeneous and resistant throughout its mass.

HIGH ABRATION RESISTANCE

Abrasion is defined as wear on the surface of one body caused by particles from another body, called an abrasive.
It is a fundamental parameter when defining the field of application of a pipe, since it will determine the use, or not, of different materials. In the case of installations that carry suspended solids, or are unblocked with hydrojet, this property must be evaluated as essential.
Wear depends mainly on four variables:
– The characteristics of the abrasive material (such as its granulometry or its chemical composition)
– The constituent material of the surface (or the constituent surface material)
– The relative speed between the surface and the abrasive material
– The frequency of the solicitation

To determine the resistance to abrasion, the overturning test is performed using the Darmstadt method. This test allows comparing the behavior of different types of pipes. As seen in the graph, high-density polyethylene has the least wear.
