Let RPM & Associates rebuild your worn coal pipe and elbows with our proven chrome carbide overlays. Welded elbows and tangents provide great coal flow and long wear life without the weight or adhesion problems of ceramic tiles. Our long-lasting, abrasion-resistant hardfacing can be applied to coal transporters from 3” to 28” diameter, and up to five times the centerline radius size. We also manufacture and rebuild ash spools, riffle housings, and a variety of other pipe-related parts used in high-abrasion environments.
