Break Seized Chain Pins Fast — No Torches. No Hammering.
Frac sand conveyor pins stuck during a critical outage.
Why Pins Seize in Frac Sand Conveyors
Frac sand packs tight, grinds surfaces, and drives corrosive abrasion into every joint. Extreme dust, heat, and constant vibration lock chain pins solid. Downtime spikes fast when stuck pins halt the conveyor and crews can’t break them loose.
Why This Failure Happens
WH132, WH157, and WDH-class pins seize when silica fines infiltrate the bushings, creating dense pack-out that loads the joint. Heat and thermal cycling expand the pin and plate bores unevenly, causing mechanical bind. High shock loads from surges deform pin shoulders, locking the chain until the pin is forcibly pressed out.
