The use of plastic drainage pipe and classification
Information: single pipe material: PVC structure in various forms: the core layer foaming pipe, a hollow wall pipe, spiral pipe, core layer foam air wall spiral pipe, spiral pipe. The existence of some problems:
(1) thermal expansion coefficient, expansion compensation device to be set up to solve.
(2) small stiffness, straight poor, need to encrypt the control card stand hanger to solve.
(3) the heat resistance is poor, the softening temperature is low, the water temperature should be restricted, the use of the place and the distance between the control and the heat source should be limited.
(4) the fire retardant is poor, in the cross floor, the roof of the roof of the house panel, the firewall, the pipe Ii Kabe department to set fire blocking ring and fire tube to solve.
(5) poor mechanical impact resistance, the need to strengthen the construction technology, carefully constructed to solve.
(6) poor sound insulation, plastic pipe noise is greater than the cast iron pipe, the pipe is installed and the pipeline location near the bedroom, the problem is particularly prominent. Noise reduction methods, improve the sound insulation effect of pipe material and core layer foamed pipe with hollow wall pipe is developed based on this idea, another way of noise reduction is changing the flow conditions, spiral pipe is developed based on this idea. Two ways to combine ideas is the core layer foaming and air wall spiral spiral tube development. Under the same conditions, the different structure forms of plastic drainage pipe, the noise measurement results: ordinary tube > core layer foaming pipe > hollow wall pipe > spiral tube drainage plastic pipe application is to replace the ordinary cast iron drainage pipe work. At present, plastic drainage pipe has been in the building height of 100m below the building, but very uneven progress in all regions. When the building height is greater than or equal to 100m of the high-rise building and not suitable for plastic drainage pipe of the occasion, can be used in flexible seismic drainage cast iron pipe.
