HEUBACH INTERNATIONAL offers an exceptional array of
Alloy 20 Pipe Flanges,
where our entire product range ensures impeccable finishing and
is performance based. These
Alloy 20 Pipe Flanges
is stabilized with Columbium to minimize carbide precipitation
during welding. Alloy 20 Slip On
Flanges
particularly excels in resisting corrosion to hot sulfuric acids
when compared to conventional stainless steels such as 316.
These
Alloy 20 Weld Neck Flanges
has excellent resistance to general corrosion, pitting, and
crevice corrosion sulfuric acid.
