- Abstract
With the increased operation duration of ball valves in west-to-east line one and line two, a growing number of ball valves are suffering inner leakage on site, which affects the site maintenance and requires an immediate remedial work for inner leakage of ball valve. Based on the analysis of the internal leakage of ball valves, a standardized internal leakage test and treatment method of ball valves is proposed, which has been verified by hundreds of experiments in the West-to-East Pipeline project, and has achieved good leaking stoppage effect. It can complete the online internal leakage fault treatment of most ball valves with internal leakage, temporarily meet the needs of on-site equipment and facilities maintenance, isolation and cut-off, and reduce the cost of the replacement of larger diameter hall valves on site, reduce the venting volume; of natural gas and its potential safety hazard, providing reliable guarantee for maintenance and repair of on-site equipment. This study can provide technical reference for the on-line stoppage of ball valve.
