Description
FRC Riser Connector
Dril-Quip’s FRC Flanged Riser Connectors are preloaded connections suitable for use in TLP or Spar high-pressure drilling riser and production riser applications. Forged heavy-duty bolts are used to make up each connection and incorporate rings to retain the bolts in the "up" position during handling. A metal-to-metal sealing ring gasket provides a gas-tight connection.
Dril-Quip’s FRC™ Marine Drilling Riser Connector combines high coupling strength with ease of operations and meets the stringent durability requirements of today’s deepwater drilling operations.
Special hydraulic wrenches ensure fast make-up and accurate preloading of the flange connectors. This quick-running, high-strength coupling is designed for easy maintenance with field replacement of most of its components. This rugged, reliable riser connector delivers maximum uptime.
FRC Connector Features:
- Made-up 6-bolt flange preloaded to 2,500 kips per API Specification 16R
- Available in preload configurations up to 5,000 kips
- Load-sharing between the choke and kill lines and the riser pipe body reduces overall joint weight
- Easy field maintenance allows replacement of connection seals when required
PR-80 and PR-85 and the OPT ZF2005 Production Riser Connectors
The PR-80 Production Riser Connector features high-tensile, high-bending and high fatigue life characteristics while maintaining easy operational features. The connector incorporates a metal-to-metal seal with an elastomeric backup.
The OPT ZF2005 Production Riser Connector features multiple metal-to-metal seals that completely isolate the threads from the environment and seal against internal gas and external liquid pressures. Both the PR-80 and ZF style of connectors are premium weld-on riser connectors and feature:
- High fatigue characteristics
- Threaded connector region is stronger than the mating pipe
- Tapered thread-form with three threads per inch and full root radius
- Dual alignment diameters engage prior to thread contact, eliminating cross-threading
- Metal-to-metal pin nose seal engages on straight diameter box seal surface
- Square shoulder spider landing area on box
- Tong grip on connector heavy wall sections
- Positive stop torque shoulder
- Field-proven performance
NF2000™ Threaded-and-Coupled Production Riser Connectors
OPT’s unique NF2000 threaded and coupled riser connector has superior field-proven operational and fatigue performance characterstics for offshore floating production platforms while providing and economical alternative to weld-on connections. They feature:
- Gas tight Metal-to-metal internal and external seals
- Internal makeup shoulder
- Patented, low-stress thread form
- Industry-leading fatigue life
- Engineered using extensive finite element analysis(FEA)
- Thoroughly tested and qualified
- Manufactured to exacting standards using OPT-developed precision gauges
- Field proven 100% reliable
