The perforation and plugging equipment consists of three different types of machinery: a perforator, a plugging tool, and a lower plugging tool. They share a common frame, which is made up of a sector gate valve, upper and lower connectors, left and right positioning fixtures, temporary bypass ports, relief valves, pressure gauges, and other components. The frame serves as a support for the perforator, plugging tool, and lower plugging tool, and uses its left and right fixing devices to connect and securely clamp the running PE pipeline. The lower connector is connected and sealed to the PE piping components; the upper connector connects and seals to the perforator, plugging tool, and lower plugging tool; the sector gate valve is an essential device for opening and closing during the equipment spring change in the perforation and plugging process. The frame is made of aluminum alloy, treated by anodizing process, featuring high surface hardness, corrosion resistance, wear resistance, and light weight.
