Pressure Relief Boring is a safe, environmentally friendly, economic, and efficient in-service pipeline maintenance and emergency repair technology, suitable for normal maintenance and modification of various medium pipelines such as refined oil and chemical media, as well as emergency repairs for sudden accidents (such as pressure maintenance, replacement of corroded pipeline sections, installation of equipment, and distribution transformation, etc.).

And this is a method for manufacturing 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 of materials, setting temperature probe monitoring points to provide connection points for equipment (plugging equipment), without the need to halt production, thereby not affecting output and material supply. Applications in the petrochemical industry include: hydrocarbons, heavy oil and light oil, diesel, crude oil, engine oil, flammable and explosive toxic gases, and a variety of chemical products.
