Pressure-bearing borehole technology is a safe, eco-friendly, economical, and efficient in-service pipeline maintenance and emergency repair technique, suitable for the regular maintenance and renovation of various media pipelines such as refined oil and chemical mediums, as well as for emergency repairs during sudden accidents (such as pressure-bearing repairs, replacement of corroded pipeline sections, installation of equipment, and distribution transformation, etc.).

And this operation is a method for creating interfaces on pipes and containers, with the pipes and containers under pressure or in use during the drilling process. Additional branch pipes are added for input/output material, with temperature probe monitoring points set for equipment (blocking equipment) to provide connection points. Drilling does not require shutdown, thereby not affecting production or material supply. Petrochemical industry applications include: hydrocarbons, heavy oil and light oil, diesel, crude oil, engine oil, flammable and explosive toxic gases, and various chemical products.
