1.descraption

1pipe wall of new-type pvc-u composite spiral muffler pipe has three composite structure smooth wall both inside and outside and the middle layer by adding nano-materials there is triangular spiral tendons along the pipeline of inside wall.in the course of drainage the flow drops in twist with the leading of triangular spiral tendons of pipe inside wall with the double roles of middle layer structure and spiral tendons it can greatly reduce the noise of pipeline system.new-type pvc-u composite spiral muffler pipe has great drainage capacity and good ventilation capacity2light weighted new-type pvc-u composite spiral muffler pipe with lower cost is very convenient to be transported installed and maintained.3the inside triangular spiral tendon of new-type pvc-u composite spiral muffler pipe has significantly strengthened role and can effectively reduce the vertical rupture phenomena caused by the impact of external force.4new-type pvc-u composite spiral muffler pipe has strong corrosion resistance and excellent anti-aging performance
