Pressure-while-Running Bore Holes is a safe, environmentally friendly, economical, and efficient in-service pipeline maintenance and emergency repair technology, suitable for normal maintenance and renovation, as well as emergency repairs of various media pipelines such as refined oil and chemical media (including pressure maintenance, replacement of corroded pipeline sections, installation of equipment, and distribution transformation, etc.).

And this is a method of manufacturing interfaces on pipelines and containers, while the pipeline and container are under pressure or in use during the hole-making process. The added branch pipelines are for input or output of materials, setting temperature probe monitoring points, providing connection points for equipment (plugging equipment), and the hole-making process does not require shutdown, thereby not affecting production output and material supply. Applications in the petrochemical industry: hydrocarbons, heavy and light oils, diesel, crude oil, engine oil, flammable and explosive toxic gases, and various chemical products.
