Description

Technical Field

[0001] This invention belongs to the field of pipeline pressurized drainage technology, specifically, it relates to a pipeline pressurized drainage device and construction method. Background Technology

[0002] Live pipeline drainage is a process of connecting, repairing, or installing accessories within a pipeline while it is in operation, without stopping or draining the fluid from the pipeline. This technology is used in many applications, including oil and gas transportation, water treatment, chemical plants, and pipeline systems. Existing live pipeline drainage requires specialized cutting equipment with appropriate cutting blades and protective mechanisms to ensure no leakage or accidents occur during the cutting process. Specially designed live check valves, shut-off valves, and safety valves are typically used in live pipeline drainage. These valves can operate under pressure while ensuring safety and reliability. Accurate pressure control within the pipeline system is crucial during live pipeline drainage. This can be achieved by installing pressure gauges and regulating valves near the drainage point to maintain an appropriate operating pressure range and prevent accidents caused by excessive pressure. Live pipeline drainage requires cutting a small hole or opening in the pipeline and connecting a drainage connector. The drainage connector allows fluid from the pipeline to be diverted into a drainage pipe or other equipment for connection, repair, or installation of accessories.
