球墨铸铁管的优点和缺点

作者: -1    发布时间: 2018-08-03    次浏览
球墨铸铁管作为一种常用的建筑材料而言它的优点与缺点都是十分的明显,先说优点,在中低压管网(一般用于6MPa以下),球墨铸铁管具有运行安全可靠,破损率低,施工维修方便、快捷,防腐性能优异等。新开发的”岩盾“系列管道可以适用于非开挖施工,广泛应用在过河、穿路、穿越建筑的管线施工中。”赛锌“系列管道则使用特殊锌铝合金外喷涂工艺,数倍提高管道的耐腐蚀性能,广泛用于腐蚀性较强的土壤施工中。

As a common building material, the advantages and disadvantages of the ball cast iron pipe are very obvious. First, the advantages, in the middle and low pressure pipe network (usually under 6MPa), the ductile cast iron pipe has a safe and reliable operation, low breakage rate, convenient and quick construction maintenance, excellent corrosion resistance and so on. The newly developed "rock shield" series pipelines can be applied to trenchless construction, and are widely used in pipeline construction of river crossing, road crossing and building crossing. The series of zine "series" pipes used special zinc and aluminum alloy external spraying technology to improve the corrosion resistance of pipelines several times. It was widely used in the construction of corrosivity soil.


球墨铸铁管的优点和缺点


但是球墨铸铁管的缺点跟优点一样都是十分的突出,比如球墨铸铁管一般不使用在高压管网(6MPa以上)。由于管体相对笨重,安装时必须动用机械。打压测试后出现漏水,必须把所有管道全部挖出,把管道吊起至能放进卡箍的高度,安装上卡箍阻止漏水。
However, the disadvantages of ductile iron pipe are as prominent as the advantages, such as ductile iron pipe is not generally used in high-pressure pipe network (6 MPa or more). Because the tube body is relatively heavy, it is necessary to use machinery when installing. When leakage occurs after compression test, all pipes must be excavated, and the pipes must be hoisted to the height where they can be put into clamps, and clamps must be installed to prevent leakage.
