PVC-U Double-walled Spiral Silencing Pipe

PVC-U Double-walled Spiral Silencing Pipe

1.he flow drops in twist with the leading of triangular spiral tendons of pipe inside wall, with the double roles of multi-holes in the wall, it can greatly reduce the noise during drainage process, caused noise is only *0% of common pipe;
2.The flow of drainage pipe is an obvious attached wall flow, which reduces the flow speed, water resistance coefficient, keeps the central air column from top to bottom of the stand pipe, smoothes the pipe pressure fluctuation, enhances its ability to control drainage and transfixion with about *5~*5% and decreases the exhaust amount of air with about *5~*0% compared with common pipes;
3.Because there is expedite air column in the pipe, it reduces the pressure inside the pipe and the pressure fluctuation, improves the pipe utilization safety coefficient;
4.The triangular spiral tendons of pipe play outstanding strengthening role, and can effectively reduce the vertical rupture phenomenon of bamboo-like caused by the impact of external forces;

II. Application Range of Ginde PVC-U Spiral Noise-abating Pipeline System

1. Residential Building Drainage
2. Agricultural Irrigation
3. Liquid Transportation

III. Production Ttechnique of Ginde PVC-U Spiral Noise-abating Pipeline System

1. Production Equipment

The production of extrusion equipments of PVC-U spiral muffler pipe is the same as that of common PVC-U pipe, the key is that the mold structure is more complex. The spiral protuberant reinforcing steel in PVC-U spiral muffler pipe is brought because of the mold mandrel rotation, straight through nose cannot make the mandrel rotate, usually using orthogonal nose, of which the *0?angle is formed by feeding direction and nose center of extrusion machine. The rotation machine is installed on the extended line of nose center, and the driving motor will make the mandrel rotate at a certain velocity by decelerating.
