Pressure Vessel Cavity Sealing

The hole sealing equipment consists of three different types of machinery: a hole punch, a sealing plug, and a lower sealing plug. They share a common frame, which is composed of a sector gate valve, upper and lower connectors, left and right positioning fixtures, temporary bypass connections, relief valves, pressure gauges, and other components. The frame serves as a support for the hole punch, sealing plug, and lower sealing plug, 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 to the hole punch, sealing plug, and lower sealing plug; the sector gate valve is an essential device for opening and closing during the equipment spring change in the hole sealing process. The frame is made of aluminum alloy, treated with anodizing, featuring high surface hardness, corrosion resistance, wear resistance, and lightweight.
