- Advantages of cast iron for heat transfer equipment are
well recognized in many fields. It combines economical first
cost with superior corrosion resistance. AX Sections are cast
gray iron of exceptionally high quality and close grain. Quality
is controlled by regular physical and chemical testing carried
on by our own completely equipped laboratories. Chaplets are
made of the same iron as the Section to eliminate the possibility
of "battery action" when electrolytes are being
handled.
- Increased wall thickness at turns, provided in all Sections,
affords protection against erosion and prevents premature
failures common to equipment not reinforced in this manner.
- For special installations where high temperatures are involved,
AX Sections can also be provided in a low chrome-nickel iron
alloy.
- For services where cooling water conditions are unusually
corrosive, these Sections can be furnished with gasketless
push nipple joints eliminating the effect of stress corrosion
of the bolts and consequent 'gasket" leaks. Also, corrosive
resistant coating applied during the manufacturing process
protects the exterior from sea water and brackish water corrosion.

The analysis of Chrome-Nickel Iron is the same except that
there is the addition of 1.75% Nickel and 0.5% Chromium.
