W型铸铁管与UPVC塑料排水管的比较

Comparison of sound insulation between w-type cast iron pipe and UPVC plastic drain pipe

铸铁管质量比塑料管大得多,更难引起振动,而且,铸铁中的石墨对振动起缓冲作用,所以,铸铁管具有很好的减振降噪性。另外,W型铸铁管采用柔性橡胶连接,也会削弱振动的传递。
The quality of cast iron pipe is much larger than that of plastic pipe, which is more difficult to cause vibration. Moreover, graphite in cast iron ACTS as a buffer against vibration. In addition, the flexible rubber connection of w-type cast iron pipe will also weaken the transmission of vibration.

PVC-U螺旋消音排水管与普通塑料排水管相比,虽然在隔音方面有所改善,但其隔音效果仍不如柔性接口铸铁管。
Pvc-u spiral silencing drain pipe has better sound insulation than ordinary plastic drain pipe, but its sound insulation effect is still inferior to that of flexible iron pipe.

UPVC塑料排水管线胀系数约为铸铁管的6倍,因而受环境温度影响自身产生的伸缩量很大,所以UPVC塑料排水管安装时一定要安装伸缩节。铸铁管的线胀系数比较低,同时铸铁排水管的柔性接口结构,使其具有较高的抗伸缩、曲挠变形能力和抗振能力。
The expansion coefficient of the UPVC plastic drain pipe is about 6 times that of the cast iron pipe, so it is necessary to install the expansion joint when installing the UPVC plastic drain pipe. The linear expansion coefficient of cast iron pipe is relatively low, and the flexible interface structure of cast iron drain pipe makes it have higher anti-expansion, flexural deformation and anti-vibration capability.

《建筑排水硬聚氯乙烯管道工程技术规程》(CJJ/T29-98)中明确规定“立管明设且其管径大于或等于110mm时,在立管穿越楼层处应采取防止火灾贯穿的措施”,即设置防火套管或阻火圈。
The building drainage pvc-u pipe engineering disciplines (CJJ/T29-98) specified in the "vertical GuanMing set and its diameter is greater than or equal to 110 mm, in the riser across the floor should be taken to prevent fires throughout measures", namely setting fire protection casing or fire collars.

铸铁管阻燃及高熔点使它有很好的防火阻燃性,不需采用防火设施。
The flame retardant and high melting point of cast iron pipe make it have good fire retardant, no need to use fire protection facilities.

虽然,铸铁管在生产技术、应用技术等方面有了大幅的提高,但其具有如此优越的性能也使其管材和管件价格高出普通UPVC塑料排水管不少,略高于PVC-U螺旋消音排水管,这也成为它在国内普及和推广的主要阻力。
Though, cast iron pipe in such aspects as production technology, application technology has improved significantly, but it has such a superior performance also make the pipe and fitting price higher than ordinary UPVC plastic drainpipe, slightly higher than the PVC -u spiral silencing drain, it also become the main resistance of its popularization and promotion in domestic.
