Valves with threaded connections; now the client prefers flanged connections

2015-09-09View Original

Thread Content

The valve inlet was originally 1\" internal thread, but the client insists on a flanged connection; therefore it needs to be changed to a combination of a 1\" flange and a 3/4\" flange. . How do people usually handle it? My idea is to create a custom flange that is simple and convenient to use, but I haven’t yet consulted anyone regarding the processing of such flanges. So I’d like to ask for everyone’s opinions.

We usually just add flanges to the piping.

A regular flange, paired with a threaded nipple – isn’t that enough?

This is my suggestion. . It’s a very simple solution. .

President Yu, are it valves, piping with flanges, or just flanges? How should the threads be matched?

Consider the length; don’t make it too long, as that won’t meet the installation requirements.

1\" 3/4\" flanges all come with standard components

I know, uh. . . What I suggest is to add a short section, followed by a standard flange below it. . . Leading this makes me think if there are any other ways. . . .

Find a flange with a weld diameter, machine the weld diameter into threads, but the bolt hole spacing may not be guaranteed during installation.

This is the simplest solution – it’s cheap and provides enough quantity. I don’t see what your boss could possibly be unsatisfied with:o

Just add threads to the flange, that’s all. :handshake
