机制柔性铸铁管建筑室内排水系统管材的最优选择

作者: -1    发布时间: 2018-07-12    次浏览

建筑室内排水管道管材的选择,应综合考虑建筑物的使用性质、建筑高度、抗震要求、防火要求及当地的管材供应条件,因地制宜选用。建筑室内排水系统的性能和使用年限在很大程度上取决于自身排水管材的优劣。


The selection of indoor drainage pipes should take into account the properties of buildings, the height of buildings, the requirements for seismic resistance, the requirements for fire prevention and the local supply conditions of pipes, and choose them according to local conditions. The performance and service life of building indoor drainage system depend largely on the advantages and disadvantages of its own drainage pipes.

建筑室内排水管材主要使用过三种材质,即陶瓷管、铸铁管和塑料管。其中陶瓷管由于重量大、易损坏、安装工作量大等原因,除特殊需要外已逐渐被淘汰,规范也不再允许使用。


There are mainly three kinds of materials used for building indoor drainage pipes, namely ceramic pipe, cast iron pipe and plastic pipe. Among them, the ceramic pipe has been gradually eliminated due to its heavy weight, easy to damage and large installation workload. Besides special needs, it is no longer allowed to be used in the specification.

灰口铸铁管:该管采用连续铸造、离心铸造和砂模铸造等方法生产,其中砂模铸造方式由于性能差已被淘汰,规范中也已作出限制。灰口铸铁管接口形式为承插式连接,承口部位形状分A型和B型两种。灰口铸铁管根据公称直径有DN50,75,100,125,150,200等6种规格。


Grey cast iron pipe: this pipe is produced by continuous casting, centrifugal casting and sand casting, among which the sand casting method has been eliminated due to poor performance and has been restricted in the specification. The joint form of grey cast iron pipe is socket joint, and the shape of the socket part can be divided into type A and type B. Grey cast iron pipe has 6 specifications according to nominal diameter, including DN50, 75, 100, 125, 150 and 200.

灰口铸铁管管件分为柔性接口和非柔性接口两种,均为承插式接口。在建筑排水中主要使用柔性接口铸铁管。按管承口部位的形状,柔性接口分为A型和RK型;按壁厚不同,柔性接口又可分为TA型和TB型。


Grey cast iron pipe fittings can be divided into two types: flexible joint and non-flexible joint, both of which are socket joint. Flexible joint cast iron pipe is mainly used in building drainage. According to the shape of pipe socket, the flexible interface is divided into A type and RK type. According to wall thickness, flexible interface can be divided into TA type and TB type.

柔性接口铸铁排水管作为一种传统的排水管材,经过工艺的更新,品质已大大提高,其综合优势也越来越明显。另外,国标(GB/T12772-1999)规定的柔性接口。铸铁管已与国际标准IS06594兼容,铸铁管的应用越来越广泛。柔性铸铁排水管及管件规格齐全,在施工中安装及维修方便,不易损坏,同时还具有抗震、抗沉降、噪声小等优点。由于在噪声、防火、技术经济性等方面的优异特性,柔性接口铸铁排水管在应用于高层建筑时有更好的前景,机制柔性铸铁管是建筑室内排水系统管材的最优选择


As a kind of traditional drainage pipe material, the flexible iron drain pipe with flexible interface has been greatly improved and its comprehensive advantages are becoming more and more obvious after the process renewal. In addition, the flexible interface specified by GB/T12772-1999. The cast iron pipe is compatible with the international standard IS06594, and the application of cast iron pipe is more and more extensive. Flexible cast iron drain pipe and pipe fittings have complete specifications, easy installation and maintenance in construction, not easy to damage, but also has the advantages of anti-seismic, anti-settlement, low noise and so on. Due to the noise, fire prevention, excellent properties of technical economy, flexible interface cast iron drainage pipe are applied in high-rise buildings have better prospects, mechanism of flexible cast iron pipe is the optimal choice of building indoor drainage pipes.

柔性接口铸铁排水管是目前国际上流行实用的排水管材,也是我国与国际水平接轨的排水管材,特别适用于高层建筑,机制柔性铸铁管是建筑室内排水系统管材的最优选择

Flexible interface cast iron drainage pipe are popular and practical international drainage pipes, also with international level of drainage pipe in our country, especially suitable for high-rise buildings, the mechanism of flexible cast iron pipe is the optimal choice of building indoor drainage pipes.
