Product Description

Pryor Giggey Co. supplied castable and plastic refractory mixes used to shield boiler tubes, patch burner throats, and rebuild furnace hearths in utility, chemical, and refining plants. According to publicly filed asbestos litigation records, certain Pryor Giggey mixes allegedly incorporated asbestos fibers to control shrinkage cracking and improve thermal shock resistance under cycling boiler loads. Refractory crews allegedly mixed the dry material with water on site, hand-packed or gunned it around tube banks, and chipped it out during outages, allegedly generating airborne dust throughout the sequence.
