6. however will flanges be classified supported Pipe Attachment?
Answer: -
Flanges are often classified supported pipe attachment as: -
Slip – on. : - The clothing sort flanges area unit hooked up by fastening within also as
outside. These flanges area unit of solid construction.
Socket Weld. : - The Socket Weld flanges area unit welded on one facet solely. These area unit used for
small bore lines solely.
Screwed. : - The Screwed-on flanges area unit used on pipe lines wherever fastening can not be
carried out.
Lap Joint. : - The splice flanges area unit used with stub ends. The stub ends area unit welded
with pipes & flanges area unit unbroken loose over identical.
Welding Neck. : - The fastening neck flanges area unit hooked up by butt fastening to the pipe. These
are used chiefly for essential services wherever the weld joints want
radiographic scrutiny.
Blind. : - The Blind flanges area unit wont to shut the ends which require to be reopened.
Reducing. : - The reducing flanges area unit wont to connect between larger and smaller
sizes while not employing a reducer. just in case of reducing flanges, the thickness
of rim ought to be that of the upper diameter.
Integral. : - Integral flanges area unit those, that area unit solid together with the piping
component or instrumentality.
