摘要:
在管道内检测中，为了减少收球时对收球设备和附属设施的损伤，提高管道内检测过程的安全性、可靠性和实用性，提出采用“二次收球”方法，即：在收清管器或内检测器场站，开启引球阀和收球阀，待收清管器或内检测器过收球筒三通后，缓慢关闭进站阀并调节其开度，使清管器或内检测器缓缓进入收球筒。以西气东输某压气站为例，从收球流程、前期准备工作等方面，将“二次收球”与传统“一次收球”作业进行对比，结果表明：“ 二次收球”方法能调节内检测器或清管器进入收球筒的速度，不但减少了对收球设备及附属设施的损害，而且明显改善了接收内检测器或清管器的安全性。
Abstract:
In order to reduce the risk in pig receiver and accessories, improving safety, reliability and practicability in pipeline inner inspection, “twice pig receiving” technique is recommended to apply in pig or inner inspection station, that is, opening both pig pilot valve and pig receiving valve, and then closing the inbound valve slowly and adjusting its opening when the receiving pig or inspection gauge passed the T-joint of pig receiver, allowing the pig or inspection gauge into the pig receiver slowly. Taking the compressor station in West-to-East Natural Gas Transmission Pipeline as an example, “twice pig receiving” operation with the traditional “once pig receiving” operation is compared from some aspects (pig receiving process, preparatory work, etc). The result indicates that “twice pig receiving” method can adjust the travelling speed of inner inspection gauge or pig into the receiver, which not only reduce the risk of pig on receiver and accessories substantially, but also obviously improve the safety of inner inspection gauge receiving or pig.
