W型铸管工程应用中应注意的几个方面之在使用时要认真把好材料质量关
Several aspects should be paid attention to in the application of w-type cast pipe engineering

由于近些年W型铸铁管的需求量逐年递增,生产厂家数量也逐步增多,市场上的产品质量良莠不齐。在使用时要认真把好材料质量关,按相应的规范进行检查验收,确保投入使用的管材必须是合格产品。
Because the demand of w-type cast iron pipe increases year by year in recent years, the quantity of manufacturer also increases gradually, the product quality on the market is mixed. When using, we should carefully check the quality of materials, check and accept according to the corresponding specifications, and ensure that the pipe materials put into use must be qualified products.

W型铸管工程应用中应注意的几个方面之安装施工应该严格按照操作工序执行
The installation and construction of w-type cast pipe should be carried out in strict accordance with the operation procedure

W型铸铁管采用平口连接,平口连接的水密性能较承插式法兰连接条件略差,因此,除了严格控制管材及管件等的本体质量外,还要特别注意管材和管件的端口保护,保证端口的圆度及平整度。
W type cast iron pipe connected by the flat, the flat connection of watertight performance is flange connection condition of slightly socket type, therefore, in addition to strictly control the quality of pipe and pipe fittings such as ontology, but also special attention to the pipe and fitting port protection, guarantee roundness and roughness of the port.

采用螺栓紧固挤压橡胶密封套的连接方式连接,密封效果除了同材料本身有关系外,还取决于螺栓的紧固程度。坚固螺栓时,最好采用由厂家配套的专用工具,这样既可以保证紧固效果又可以提高工作效率。
The sealing effect is not only related to the material itself, but also depends on the fastening degree of bolts. When firm bolt, had better use the special tool that supports by the manufacturer, can assure the effect of fastening already can improve working efficiency.

W型铸管工安装施工应注意要严格遵守施工质量验收规范和有关技术规程,做好管道支、吊架的设置等工作。
The installation and construction of w-type cast pipe workers should pay attention to strict compliance with the construction quality acceptance specifications and relevant technical regulations, as well as the installation of pipeline supports and suspension frames.

选用何种排水管材为最优应结合建筑使用功能来考虑,在居住建筑中应首先考虑选用柔性铸铁排水管,接口方式首先考虑W型。
The optimal drainage pipe material should be considered in combination with the function of the building. In residential buildings, flexible cast iron drainage pipe should be considered first, and the type W should be considered first for the interface method.

国家已经发布了新的国家标准,使设计人员、施工人员有据可依。然而,目前市场上的产品质量鱼龙混杂,还需严格管理。同时,施工企业还要不断提高施工技术,以利于管材的推广和普及。
The state has issued new national standards to enable designers and construction workers to follow. However, the quality of products on the market is mixed and needs strict management. At the same time, construction enterprises must constantly improve the construction technology, so as to facilitate the extension and popularization of pipe materials.
