Product Description

Aluminum Cap Flange

Aluminum Cap Flange is also called blind plate aluminum flange, blind plate. It is an aluminum flange without a hole in the middle for sealing the pipe plug. The function is the same as the welding head and the threaded pipe cap, except that the blind plate aluminum flange and the threaded pipe cap can be removed at any time, while the welded head cannot.

This standard applies to Aluminum Cap Flange with a nominal pressure of PN≤1.0Mpa.
