Blind flange. It is a flange without a hole in the middle, mainly used to seal the front end of pipelines, such as for sealing nozzles. Its function and head and sleeve structure are the same, the difference is that the blind plate sealing ring is detachable, and the head sealing ring cannot be opened again. Blind plate materials include carbon steel, alloy steel, stainless steel, plastic, etc.
The isolation, cutting effect, sealing head, and sleeve functions are the same. Due to its good sealing performance, it can be completely isolated from the system and is usually used as a constant isolation method. The blind plate is solid with a handle.
Ontology, commonly used in isolation systems. Flange blind plates are more convenient, and when separation is required, use the end of the blind plate; When normal operation is required, use a yellow throttle ring; It can also be used to fill blind plates onto pipelines.
Installation gap. At the same time, the flange blind plate is clearly marked for easy identification of installation status.
A flange is a component that connects pipes, usually located at the end of the pipe. The flange has perforations, and bolts are required to fix the two flanges together during connection. flange gasket
Chip seals play a sealing or temporary damage role in experiments. Flanges are common disc-shaped components in pipeline engineering. Usually, flanges are used in pairs. According to different connection methods, the position of flange points also varies.
They include threaded flanges, welded flanges, and clamping flanges. Low pressure pipelines can be connected by threads, while pipelines with a pressure exceeding 4 kilograms can be connected by welding.
