Polypropylene (PP) is a high-quality material that has shown proven performance advantages since the 1950s. Since then, there has been an average global increase of 9% per year in the production and consumption of plastics, which has been driven by continuous innovations in the material. (PP was specified for the production of sewage pipes in the 1970s).
PP’s intrinsic properties of high-impact resistance combined with good stiffness and excellent chemical (see chemical resistance) and temperature resistance; good tensile strength; inertness toward acids, alkalis and solvents have secured its position for use in a wide range of consumer and industrial applications.
Polyolefin pipes show the lowest abrasion compared to other materials due to a very low surface roughness (approximately 0.007 mm). Due to this, PP pipes have excellent hydraulic capacity, allowing them to drain waste water even at low gradients.See technical data and MSDS in the products section.
The need to improve humankind’s quality of life has led to the treatment all types of pollution — most of which are created by humanity itself. Noise, particularly noise generated by people, is a treatable pollution in almost every living environment.
Disruptive noises in buildings have triggered the pursuit of solutions to minimize noise pollution. Architectural sound protection measures are most relevant in buildings where people spend relatively long periods (e.g., especially residences and offices). Disturbing noise is mainly caused by sources within the construction itself (“structure-borne noise”), most often from building engineering systems that either directly or indirectly give rise to noise.
Noise from wastewater and drainage systems
Every object in motion makes noise when it transmits vibrations – in the form of pressure or negative pressure waves – to the surrounding air. There are two types of noise in drainage and wastewater systems:

Huliot’s systems has been tested and certified according to the most stringent European standards for fire safety of building materials.
The Ultra Silent™ system is certified according to EN 13501-1:2009 by IBS and classified D-s2, d2. This standard defines classes of burning behavior for building materials and specifies the requirements and test methods for each class. The classification of reaction to fire and valid practical range of application is contained in the representational classification report. The Ultra Silent system is certified according to DIN 4102-1 by SKZ and classified B2. This standard defines classes of fire behavior for building materials and specifies the requirements and test methods for each class. The test method measures the ignitability of building products when exposed to a small flame.
Huliot offers the HT system both with B1 or B2 classification, according DIN 4102-1.
Huliot’s Ultra Silent™ and PP-ML pipes can be protected with ESHCOLLAR™ fire-stopping collars for plastic pipes made from stainless steel with an inlaid graphite-based intumescent. ESHCOLLAR™ has a starting temperature of approximately 150 °C, with highly efficient performance and non-ageing certification (tested and approved according to EN 1366).
