1.Specifications and parameters of titanium flanges and their testing methods
Titanium flange is made of non-ferrous metal titanium or titanium alloy to make the pipe and pipe connected to each other, connected to the pipe end.
There are holes in the titanium flanges and the two flanges are connected by bolts.The flanges are sealed with gaskets.Flanged pipe fitting refers to a pipe fitting with a flange (protruding edge or joint plate).
It may consist of threaded joint or welded.Flange connection is composed of a pair of flanges, a gasket and a number of bolts and nuts.The gasket is placed between the sealing surfaces of the two flanges. After tightening the nuts, the specific pressure on the surface of the gasket will be deformed when it reaches a certain value, and the uneven places on the sealing surface will be filled to ensure the connection is tight and leakless.
According to the structure type, there are integral titanium flange, butt-welded titanium flange, looper titanium flange and threaded titanium flange.
