All Kinds Of Flanges/Carbon Steel Flanges/Sorf/Wnrf/Blind Flanges
Carbon Steel Flange BL
Product Description:
This kind of flange is made of steel,and stainless steel,and carbon
steel,we have all main standards in the world,you can find what you
want in our factory.the measurement from dn 40 to dn 2000.
Welding neck flange have two forms (shapes), one with reducing neck
as we called reducing weld neck flange; One with a even diameter of
typical long neck named as long neck weld flange.
Weld neck flange (WN flange) has a neck that can relocated stress of the pipe, so to reduce the
pressure that gathered in the flange bottom. It is compatible to
the pipelines that works in high or low temperature and bear high
pressure. Specially for the pipe or the valves when PN is larger
than 2.5 Mpa.
