Steel Pipe Flange ASTM A350 LF2 CL1 Flange ,Forged ,DN 250MM 900LB Oiled RF Connection between Pipe and Flange
Flange, from English Flange, also known as flange or flange. Basic meaning refers to the protruding structure on an object, or an object with a raised structure, such as flange bolts, flange shafts, etc. Because the flange structure is commonly used in connection between shaft and shaft, between pipe end and pipe end or between equipment and equipment, the flange generally refers to a part or structure used for connection in the mechanical field, such as pipe flange, reducer flange.
Loose flange
Loose sleeve flange is commonly known as looper flange. It is
divided into welding ring looper flange, flanging looper flange and
butt welding looper flange, mostly used in copper, aluminum and
other non-ferrous metals and stainless steel pipes. The connection
of the loose sleeve flange is also realized by welding, but the
flange is a loose sleeve on the attached workpiece that has been
welded to the pipe, and then the accessory element and gasket are
pressed to seal by connecting bolts. The flange (that is, the loose
sleeve) itself does not touch the medium. The advantage of this
flange connection is that the flange can be rotated, easy to pair
the middle bolt hole, easy to install on the large diameter pipe,
and also suitable for where the pipe needs to be removed frequently
for co-cleaning and inspection. The flange accessories are
consistent with the pipe material. The flange material can be
different from the pipe material, so it is more suitable for
conveying corrosive medium. But loose sleeve flange pressure is not
high, generally only suitable for low-pressure pipe connection.
