The perforation and sealing equipment is composed of three different-purpose machines: the perforator, the sealing device, and the lower sealing device. They share a common frame, which is made up of components such as the sector gate valve, upper and lower connectors, left and right positioning fixtures, temporary bypass connections, relief valves, and pressure gauges. The frame serves to provide a base for the perforator, sealing device, and lower sealing device, while also using 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 separately to the perforator, sealing device, and lower sealing device; the sector gate valve is a crucial device for opening and closing during the equipment spring change in the perforation and sealing process. The frame material is made of aluminum alloy, treated with anodizing, and features high surface hardness, corrosion resistance, wear resistance, and light weight.
