Noise level in the pipeline

Noise in nature

Noise in the nature is unwished or harmful sound to human health and the environment in outer space caused by human activity including noise emitted by means of transport, road transport, railway transport, air transport, maritime and inland waterway transport as well as the plant and projects for which the special regulations in the field of environmental protection shall obtain a decision on integrated environmental protection requirements or decision on environmental impact on the environment.

Noise protection

Noise protection in buildings is a very demanding task for architects and builders while planning and constructing. The flow of wastewater through the sewage systems is one of the possible sources of noise in buildings.

Soundproofing of house drainage installation systems has gained in importance due to the high demands of comfort living. The total noise can be significantly reduced by selecting the appropriate piping system. The types and the vibration of pipes depend on various factors such as the weight of pipes, the material and its internal insulation. Pipes produce air noise caused by vibration and vibration noise caused by fixation on installation wall.

Noise reduction is achieved by using:

1. Special materials in the manufacture process

2. Using special clamps with rubber clamp

Sound levels for different types of drainage pipes:

Reducing noise in homes and workplaces has become an essential criteria for better quality

of life and working environment. For this reason we began researching and testing sound

insulation properties of materials used in ALMAPLAST systems. Tests on sound insulation properties of ALMAPLAST PLUS system were conducted at the Fraunhofer Institute in Stuttgart, the world known laboratory for testing audio performance. Research results have shown that the system ALMAPLAST PLUS fully complies with the applicable standards.

In accordance with the European standard EN 14366, and for testing purposes, installation system ALMAPLAST PLUS is used with pipes DN 110 x 3,6.

Test results:

Test results obtained by measuring the water flow rate of 2 l / s indicate that the installation system ALMAPLAST PLUS does not exceed the noise levels higher than 17 dB (A).
