利用发送接收清管器的方法对新管线进行清管,清理管线内的积液和异物,是新建管线投产前的必须进行的保证措施,也是湿气管线在入冬前的一项重要工作。统称为管线的清管作业,在清管作业中,要有大量的天然气被放空,从管线中清理出来的积液和异物如果处理不当,极易对环境造成污染。为此,如何在保证管线畅通,不冻堵的前提下,消除管线清管作业所产生的环境污染和气量损失。本文从天然气集输管道生产运行和清管作业操作方式方面,提出了解决问题的相应措施,以及在生产实践中较为有效地操作方式方法。
Using the method of sending and receiving pigs to clean the new pipeline to clean up the liquid and foreign matter in the pipeline is a guarantee measure that must be carried out before the new pipeline goes into operation and is also an important work of the moisture pipeline before winter. Collectively referred to as pipeline pigging operations, in the pigging operations, there must be a lot of natural gas is venting, clean up from the pipeline effluent and foreign body if handled properly, easily lead to environmental pollution. To this end, how to ensure that the pipeline is smooth, not blocking the premise of the premise, to eliminate pipeline pigging operations caused by environmental pollution and gas loss. This paper puts forward the corresponding measures to solve the problems and the more effective methods and methods of operation in the production practice of natural gas gathering pipelines for production and operation and pigging operations.
