浅析UPVC排水管与铸铁排水管差异性

作者: -1    发布时间: 2018-07-12    次浏览

1、浅析UPVC排水管与铸铁排水管差异性之材质。UPVC排水管和铸铁排水管密度分别为1.50g/cm3和7.2g/cm3,后者约是前者的5倍。因此,UPVC排水管在施工中运输及操作强度比较小。


1. Briefly analyze the different materials of UPVC drain pipe and cast iron drain pipe. The density of UPVC drain pipe and cast iron drain pipe is 1.50g/cm3 and 7.2g/cm3 respectively, which is about 5 times of the former. Therefore, the UPVC drainpipe has a small transportation and operating intensity during construction.

2、浅析UPVC排水管与铸铁排水管差异性之安装工效。UPVC排水管采用粘接接口,粘合容易,且易切割,上下安装次序自由;铸铁排水管的接口工序复杂,需打麻、调制接口材料、打头、养护等。可见,UPVC排水管安装工效明显要高于铸铁排水管。


2. Analyze the installation efficiency of the difference between UPVC drain pipe and cast iron drain pipe. UPVC drain pipe adopts adhesive interface, which is easy to be bonded, easy to cut and free to install up and down. The interface procedure of the cast iron drain pipe is complex, it needs to be hemp, adjust the interface material, punch and maintain. It can be seen that the installation efficiency of UPVC drain pipe is obviously higher than that of cast iron drain pipe.

3、浅析UPVC排水管与铸铁排水管差异性之外观及耐腐蚀性。UPVC排水管一般为白色,根据加入填料不同,可生产出多种不同颜色管材,色泽明快、光亮平滑,耐腐蚀,无需作防腐和其他装饰处理。铸铁排水管材质粗糙、易生锈,外壁需作防腐处理,大约每两年要外刷一次。


3. Briefly analyze the appearance and corrosion resistance of the difference between UPVC drain pipe and cast iron drain pipe. The UPVC drain pipe is usually white, which can produce a variety of pipes of different colors according to different fillers. The color is bright, bright, smooth and corrosion resistant. Cast iron drain pipe material is coarse, easy to rust, the outer wall needs to be treated with corrosion, about every two years to brush.

UPVC排水管具有运输搬运方便、节省空间、美观多样、排水能力强、造价低和安装工效高等优点,但存在着隔音及防震效果差、防火性能低、抗拉抗弯强度低等缺点。


UPVC drainage pipe with transport handling convenient, save a space, beautiful diversiform, drainage capability, low cost and installation efficiency higher advantages, but there is a poor sound insulation and shock effect, low fireproof performance, low tensile and bending strength of faults.

柔性接口铸铁排水管具有抗拉抗弯强度比较高、噪音小、使用寿命长(一般在50年以上)等优点,但造价比较高,安装工效相对UPVC排水管也比较低。


Flexible interface cast iron drainage pipe has high tensile and bending strength, low noise, long service life (generally in more than 50 years), but the cost is higher, relative UPVC drainage pipe installation work efficiency is low.

建议应该从建筑物的使用功能上考虑选取合适的排水管材:在超高层建筑、住宅和宾馆中应首先考虑采用柔性接口铸铁排水管,在对噪声环境、防火和防震要求较高的建筑中应强制采用柔性接口铸铁排水管;

Proposal should consider to choose the right from the use function of the building drainage pipes: in a tall building, residential and hotel should first consider using the flexible interface cast iron drainage pipe, in the noise environment, fire prevention and shockproof requirements higher buildings should be forced to adopt flexible interface in the cast iron drainage pipe;
