Cast Hydraulic Fracking (Fracturing) Components cost less, last up to 6 times longeron January 17, 2011
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.
