Product Description
Haokun's series of blind flange is a flange without hole in the middle, which is used to seal the pipe plug. Its design permits easy access to vessel or piping system for inspection purposes. The function is the same as that of welded head and threaded pipe cap, except that blind flange and threaded pipe cap can be removed at any time, while welded head is not. It can be supplied with or without hubs at the manufacturer’s option. In terms of internal pressure and bolt loading, blind flanges, especially in the larger sizes, are the most highly stressed flange types.
