1. 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.

  2. 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.

  3. For special installations where high temperatures are involved, AX Sections can also be provided in a low chrome-nickel iron alloy.

  4. 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.
