Product Description
Dresser-Rand (successor to Dresser Industries’ Clark-Dresser reciprocating compressor line and Ingersoll-Rand’s Painted Post reciprocating heritage) allegedly supplied large horizontal reciprocating gas and process compressors to natural-gas pipeline compressor stations, gas processing plants, refineries, and chemical facilities. Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Dresser-Rand reciprocating compressor piston-rod stuffing boxes were originally packed with braided asbestos rope or asbestos-loaded rod-seal rings, and that compressed asbestos sheet gaskets were installed at cylinder heads, suction and discharge valve covers, distance pieces, and unloader housings.
Reciprocating compressor “valve and packing” changes were routine maintenance — often on a fixed calendar interval — and each event allegedly required the rod-seal packing to be pulled and repacked and every cylinder-cover and valve-cover gasket to be scraped free of its mating surface before a fresh asbestos gasket was cut and installed. The frame distance pieces, in which the packing sits, concentrated packing debris in a location that mechanics reached into with bare hands.
Workers Exposed
- Compressor mechanics at pipeline compressor stations and gas plants performing scheduled valve-and-packing changes on Dresser-Rand frames.
- Millwrights rigging cylinders, frames, and coupling components during major Dresser-Rand overhauls.
- Pipefitters (UA) breaking suction, discharge, and fuel-gas piping into Dresser-Rand compressor cylinders.
- Machinists re-babbitting crossheads, honing cylinders, and rebuilding rod-packing cases.
- Instrument fitters working associated pulsation-bottle and control tubing during outages.
Bystanders in the compressor building were exposed to airborne fibers released by packing removal, gasket scraping, and sweep-up of asbestos debris after each valve-change round.
