Pressure-while-Running Boreholes are a safe, environmentally friendly, economic, 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 repairs, replacement of corroded pipe sections, installation of equipment, and distribution transformation, etc.).

And this operation is a method for manufacturing interfaces on pipes and containers, with the pipes and containers under pressure or in use during the drilling process. It adds branch pipes for input or output of materials, sets temperature probe monitoring points for providing connection points to equipment (shut-off equipment), and drilling does not require shutdown, thus not affecting production and material supply. Applications in the petrochemical industry: hydrocarbons, heavy and light oil, diesel, crude oil, engine oil, flammable and explosive toxic gases, and various chemical products.
