WELD NECK FLANGE ASTM B16.5 B16.47 SERIES B A105 A105N 150# STD
SCH40
Description:
A weld neck flange is a type of flange that is designed to be butt
welded to a pipe. It has a long tapered hub and a rounded end that
is used to connect to the pipe. The flange is designed to provide a
high strength, leak-proof joint that is able to withstand high
pressures and temperatures.
The weld neck flange is typically used in high-pressure
applications, such as in the oil and gas industry, chemical
processing, and power generation. It is also commonly used in
piping systems where there is a need for easy access for cleaning,
inspection, or modification.
One of the key advantages of a weld neck flange is that it provides
a smooth transition from the pipe to the flange, which helps to
reduce turbulence and flow resistance. This helps to improve the
overall efficiency of the piping system.
Weld neck flanges are available in a variety of materials,
including carbon steel, stainless steel, and alloy steel, and in a
range of sizes and pressure ratings. They are also available in
different facing types, such as raised face, flat face, and ring
joint face, to suit different application requirements.
