Description
POLYPROPYLENE PLASTIC PIPES FOR USE IN WASTEWATER DRAINAGE STACK Field of the InventionThe invention relates to polypropylene plastic pipes for use in wastewater drainage stacks.
Background of the Invention Polypropylene plastic pipes for use in wastewater drainage stacks are required to meet technical standards including inter alia: EN 1451-1:2017 (E) – Plastics piping systems for soil and waste discharge (low and high temperature) withing the building structure - Polypropylene (PP) – Part 1: Specifications for pipes, fittings and the system, , the contents of which are incorporated reference by reference. EN 1451- 1:2017 (E) published November 2017 is directed towards single layer polypropylene plastic pipes.
EN 13476-2:2018 (E) - Plastics piping systems for non-pressure underground drainage and sewerage - Structured-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) – Part 2: Specifications for pipes and fittings with smooth internal and profiled external surface and the system, Type A, the contents of which are incorporated herein by reference. EN 13476-2:2018 (E) published April 2018 is directed towards multi-layer plastic pipes.
EN 1451-1:2017 (E) hereinafter abbreviated to the EN 1451 standard and EN 13476-2:2018 (E) hereinafter referred to as the EN 13476 standard and are available from CEN-CENELEC Management Centre: Rue de la Science 23, B-1040 Brussels www.cencenelec.eu. EN 1451 and EN 13476 refer to standard tests for testing a wide range of pipe specifications but omit a soundproofing test since soundproofing is regulated with regards to a building structure. Exemplary soundproofing technical standards for a building structure include: Israel Standard IS 1004 Part 4: Acoustics in Residential Buildings: sound Pressure Level from Sanitation Installations: Requirements and Test Methods commercially available from: https://www.sii.org.il/he/%D7%93%D7%A4%D7%99-%D7%9C%D7%95%D7%91%D7%99/%D7%9B%D7%9C%D7%9C%D7%9 9/%D7%AA%D7%A7%D7%99%D7%A0%D7%94/%D7%93%D7%A3- %D7%AA%D7%A7%D7%9F/?id=b5a81950-4486-4227-a0e3-7584a96a38ec DIN 4109 Sound Insulation in Buildings commercially available from https://www.en-standard.eu/din-4109-1-schallschutz-im-hochbau-teil-1- mindestanforderungen / DIN EN 14366:2004+A1:2019 German version: Laboratory measurement of noise from waste water installations commercially available from https://www.techstreet.com/standards/din-en-14366?product_id=21005 To assist a building structure to meet soundproofing requirements, it is known to add a mineral compound to a base plastic material to form a mineral compound plastic mixture which has a greater density compared to the base plastic material thereby resulting in a heavier pipe per meter than without the mineral compound. Moreover, it is also known that increasing a mineral compound's wt% leads to increased density and soundproofing.
Applicants manufacture and supply soundproofing polypropylene plastic pipes under the trade name ULTRA-SILENT. Such polypropylene plastic pipes have a triple layer construction including: Black polypropylene outermost layer for impact resistance and UV protection. Mineral reinforced polypropylene intermediate layer for high mechanical resistance and sound reflection for effecting soundproofing. And white polypropylene innermost layer for flow performance and high definition contrast for visual inspection.
The black outermost layer and the white innermost layer are typically constituted by similar polypropylene material combined with different colored pigments.
There is a need for soundproofing polypropylene plastic pipes for use in wastewater drainage stacks.
Summary of the Invention The present invention is directed toward soundproofing polypropylene plastic pipes for use in wastewater drainage stacks having a concentric construction including a soundproofing intermediate composite between a conventional polypropylene outermost layer and a conventional polypropylene innermost layer. The soundproofing intermediate composite includes a synergistic soundproofing combination of at least one high density layer for sound reflection and at least one foamed polypropylene layer for sound absorption. The high density layer has a thickness THD and a density of between about 1.0 g/cm and about 2.5 g/cm. The foamed polypropylene layer has a thickness TF ≥ 2 THD and a density of between about 0.4 g/cm and about 0.85 g/cm. The soundproofing polypropylene plastic pipes of the present invention can be designed to have at least equivalent soundproofing capability as a conventional soundproofing polypropylene plastic pipe while being lighter per meter by virtue of the use of foamed polypropylene which also reduces carbon footprint. Reducing weight per meter facilitates transportation to a building structure, handling at a building structure, and the like. The soundproofing polypropylene plastic pipes of the present invention can be manufactured to meet presently applicable technical standards EN 1451- 1:2017 (E) and EN 13476-2:2018 (E). These technical standards can be superseded in time. The teachings of the present invention can be equally applied to future technical standards relating to plastics piping systems for use in wastewater drainage stacks.
