Pressure Retaining Hole is a safe, environmentally friendly, economical, and efficient in-service pipeline maintenance and emergency repair technology, suitable for normal maintenance and reconstruction of various medium pipelines such as finished oil and chemical media, as well as emergency repairs for sudden accidents (such as 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, while the pipes and containers are under pressure or in use during the drilling process. An additional branch pipe is added for input or output of materials, setting temperature probe monitoring points to provide connection points for equipment (shut-off equipment). Drilling does not require shutdown, affecting neither production nor material supply. Petrochemical industry: hydrocarbons, heavy oil and light oil, diesel, crude oil, engine oil, flammable and explosive toxic gases, and various chemical products.
