Detailed Specifications & Operational Features
Our WSB annular BOP features a reliable, compact design with retrofittable swarf seal technology.
• Rugged, reliable spherical type sealing element – Provides positive seal after hundreds of tests to full working pressure
• Enhanced swarf seal – Designed to help prevent metal-to-metal damage from swarf entering the piston when performing milling
• Strong, simple construction – only five major parts
• Compact body saves space – Height is 15 to 20% less than equivalent annular BOP designs
• Simple hydraulic system – Optimized to only require two hydraulic connections for operation
• Wear rings on moving parts – Feature prevents metal-to metal contact, allowing for prolonged preventer life.
• Resistant to corrosive environments – Standard models are suitable for internal H2S service, and simple bolt and lifting shackle changes convert them for external H2S service.
• Ease of Service – Element can be replaced without contamination of mud or grit into the hydraulic system
