铸铁管与碳钢管的连接一般采用铸铁承插短管连接方法。可是如果要求施工时间很短,这种方法就不适合了,因为打口水泥在短时间内不会凝固。下面以我厂处理(?)219碳钢管和 DN200铸铁管连接的实例介绍一种新的连接方法。我厂给水管道多采用铸铁管,在二期续建工程中,新系统的碳钢管要与老系统的铸铁管连接,且停水时间只有4h,为了在规定的时间内完成两管连接 Cast iron pipe and carbon steel pipe connection generally use cast iron socket short pipe connection method. However, this method is not suitable if the construction time is short, because the cement will not solidify in a short time. The following example shows how to handle the connection of 219 carbon steel pipe and DN200 cast iron pipe in our factory. I plant more water pipe using cast iron pipe, in the second phase of the continued construction of the new system of carbon steel pipe with the old system of cast iron pipe connection, and no water for only 4h, in order to complete the two connections within the specified time
