Pressure-while-running hole-making is a safe, eco-friendly, economic, and efficient in-service pipeline maintenance and emergency repair technology, suitable for normal maintenance and改造, as well as emergency repairs (such as pressure maintenance, replacement of corroded pipe sections, installation of equipment, and distribution改造) of various media pipelines, including refined oil and chemical mediums.

And this is a method for manufacturing interfaces on pipes and containers, where the pipes and containers are under pressure or in use during the drilling process. Additional branch pipes are added for input or output material, and temperature probe monitoring points are set to provide connection points for equipment (blocking equipment). Drilling does not require shutdown, thus not affecting production or 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.
