Pressure-while-buried hole is a safe, eco-friendly, economic, 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 in case of sudden accidents (including pressure maintenance, replacement of corroded pipe sections, installation of equipment, and division and delivery transformations, etc.).
And this is a method for manufacturing interfaces on pipelines and containers, where the pipes and containers are under pressure or in use during the drilling process. An additional branch pipeline is added for material input/output, and temperature probe monitoring points are set to provide connection points for the equipment (blocking equipment). Drilling does not require shutdown, thus it does not affect production or material supply to the petrochemical industry: hydrocarbons, heavy oil and light oil, diesel, crude oil, engine oil, flammable and explosive toxic gases, and a variety of chemical products.
