Noise-reducing pipe with ribbed inner wall designed to minimize sound from wastewater flow. Ideal for quiet zones in residential, hotel, or hospital settings. Combines acoustic performance with strong structural integrity and easy socket connections.
The PVC-U Ribbed Inner Wall Silencing Pipe is specially designed for low-noise drainage systems, offering enhanced acoustic performance through its inner ribbed structure. Manufactured from unplasticized polyvinyl chloride (PVC-U), the pipe combines excellent flow capacity with superior sound insulation — ideal for use in residential buildings, hospitals, hotels, and other noise-sensitive environments. The ribbed inner surface disrupts sound waves generated by water flow, significantly reducing pipe noise compared to traditional plain-wall pipes.
