Pressure-leak opening is a safe, eco-friendly, economical, and efficient in-service pipeline maintenance and emergency repair technique, suitable for the normal maintenance and reconstruction of various media pipelines such as finished oil and chemical mediums, as well as emergency repairs for unexpected incidents (such as pressure maintenance, replacement of corroded pipeline sections, installation of equipment, and distribution transformation, etc.).

And this is a method of creating interfaces on pipelines and containers, where the pipeline and container are under pressure or in use during the drilling process. Additional branch pipelines are added for input/output material settings, temperature probe monitoring points, providing connection points for equipment (blocking equipment), and drilling does not require shutdown, thus not affecting production and material supply. Petrochemical industry: hydrocarbons, heavy and light oils, diesel, crude oil, engine oil, flammable and explosive toxic gases, and a variety of chemical products.
