API-16C-Compliant Sealing Materials

Trelleborg Sealing Solutions received approval for 25 materials to American Petroleum Institute API-16C specification relative to oil and gas choke and kill valve requirements. This represents the largest number of materials compliant to the standard available from any seal manufacturer, according to Trelleborg. The certification dictates a brine/diesel chemical composition that can be aggressive to seal materials. The company has engineered polymers and elastomers to withstand these chemicals with particular attention on minimizing effects of chemical attack. The materials are particularly suited for applications including rotating disc-type, adjustable, barrel-type, and orifice choke valve types and include polytetrafluoroethylene (PTFE) based, PEEK and elastomeric compounds, such as hydrogenated nitrile butadiene rubber (HNBR), fluoroelastomer (FKM), and perfluoroelastomer (FFKM).
