旧管道更换为钢丝网骨架复合管需要注意什么?衔接技巧​

2025-09-18

在管道系统的更新改造中,将旧管道更换为钢丝网骨架复合管是一项常见且重要的工程。那么,在这个过程中需要注意什么呢?

首先是管材的选择与检查。要确保钢丝网骨架复合管的质量符合相关标准,检查管材是否有破损、裂纹等缺陷。同时,根据实际需求选择合适规格的管材,包括管径、壁厚等参数。

旧管道的拆除环节也不容忽视。在拆除旧管道时,要小心操作,避免对周边环境和其他设施造成损坏。对于一些老旧且粘连严重的管道,更要耐心处理,防止因拆除不当引发新的问题。

衔接技巧是关键。在连接钢丝网骨架复合管时,接口处理至关重要。要保证接口的清洁,去除油污、杂质等。采用合适的连接方式,如电熔连接等,严格按照操作规程进行。连接过程中,要控制好温度、时间等参数,确保接口连接牢固、密封良好。

管道的固定也很重要。更换后的钢丝网骨架复合管要进行合理的固定,防止因外力作用导致管道移位、变形等。固定点的间距要符合规范要求,固定方式要牢固可靠。

施工过程中的监测同样不可少。在更换和衔接过程中,要实时监测管道的压力、流量等参数,及时发现并解决可能出现的问题。

总之,将旧管道更换为钢丝网骨架复合管,从管材选择、旧管拆除到衔接固定、施工监测,每一个环节都需要精心对待,掌握好衔接技巧,才能确保管道系统更换后的稳定运行,为后续的使用提供可靠保障。
