PPHM double-wall corrugated pipe, also known as polypropylene double-wall corrugated pipe, is a corrugated pipe made of PPHM material, the inner wall is smooth, the outer wall is corrugated structure, made of suitable materials, both strength and flexibility, suitable for a variety of liquid transportation scenarios, easy installation. Directly from the manufacturer, support wholesale, consult and contact 13339996652. The specifications and models are rich, the common outer diameter covers 110mm, 160mm, 200mm, 315mm, 400mm, 500mm, 630mm, 800mm, 1000mm, 1200mm, etc., the length of a single root is mostly 6 meters, the wall thickness is adjusted with the increase of the pipe diameter, the corrugated spacing is designed according to the structural strength, and the interface adopts socket connection to adapt to different engineering laying needs. Wide range of use scenarios, suitable for municipal drainage and sewage projects, rainwater drainage in residential areas, farmland irrigation pipelines, industrial mild wastewater transportation, etc., the inner wall is smooth to reduce water flow resistance, the outer wall ripples enhance impact resistance, suitable for underground burial, ground laying and other environments, easy to maintain, ensure long-term smooth pipeline.
