Pressure-pipe drilling is 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 maintenance, replacement of corroded pipe sections, installation of equipment, and distribution transformation, etc.).

And this is a method for creating 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. Petrochemical industry: hydrocarbons, heavy oil and light oil, diesel, crude oil, engine oil, flammable and explosive toxic gases, and a variety of chemical products.
