Product Description

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that John Zink Company supplied refinery flare systems — elevated flares, ground flares, and enclosed flares — with asbestos-fabric heat shields at the flare tip and asbestos-refractory base insulation on the pilot-assembly mounting plate. The asbestos-fabric heat shield allegedly protected upper riser flanges and the wind fence from radiant flame heat, and the asbestos-refractory pilot base allegedly withstood the continuous pilot flame at the ignition assembly.

Plaintiffs alleged that John Zink flare tips and pilot assemblies remained in service across U.S. refineries and petrochemical plants from the 1940s through the 1980s, requiring periodic tip change-outs and pilot-assembly rebuilds by crane and rope-access flare-tip crews.
