Penticton Foundry supplies ASTM A532 chrome iron fracking components that outlast fabricated components.
The blender tubs, liner and mixing impellers used in the fracking process are ASTM A532 CLIII A (or 3A) chrome iron castings. The cast components usually last at least 6 times longer than T1 fabricated plate overlayed with CCO. (chromium carbide overlay)
The impeller is cast, machined and balanced. Hardness is >550 BHN (55RC)
One of our customers trialed a sample ASTM A532 chrome iron cast impeller. It was finally replaced after pumping 50,000 tons (100 million pounds) of proppant. The prior steel impellers wore out after only 8,000 tons.
