A solid wall pipe with a smooth outer surface and spiral edges on the inner surface, generally white in color, and other colors can be agreed upon by the supply and demand parties. The evenly distributed spiral edges have a certain guiding effect, which can effectively improve drainage flow and reduce drainage noise. It is mainly used in conjunction with swirl pipe fittings and is applied to building drainage risers. 1、 Purpose: Mainly used for building drainage, especially suitable for places with high noise reduction requirements such as hospitals, schools, and high-end residences. It is also suitable for large buildings such as commercial complexes and office buildings, and can efficiently discharge domestic sewage and rainwater. ​ 2、 Advantages Significant noise reduction: The spiral structure on the inner wall guides the water flow to adhere to the wall, reducing collisions and reducing noise by 5-18% compared to ordinary pipes dB。 ​ Efficient drainage: The water flow is orderl…
