Long Neck Welding flange

Long Neck Welding flanges (abbr.
LWN)  are similar to a standard Welding Neck
flange, but the “Neck” is considerably longer. This type is often used as a
nozzle for a barrel or column. In addition, there are the type LWN Heavy Barrel
(HB) and the Equal LWN Barrel (E); they have a different shape and a thicker
“Wall”.

Long Neck Welding flanges  are unique due to their simple connectivity with
other pipes. Moreover, our products are extensively used in refining industries
for linking purposes. Our esteemed patrons can avail these qualitative range of
flanges from us at industry-leading prices.
