Patented slip element aids wellhead performance
These Hercules aboveground and submergible casing and tubing heads are designed for use in PC, ESP, and beam pump applications.
All Hercules wellheads feature a patented slip element with a positive mechanical stop that limits slip travel and reduces hoop stress in the wellhead body. It also transfers as much weight as the threaded connection can withstand without crushing the casing ID below API drift diameter. In addition, units feature pressure-assisted, contoured packing for positive pack-off with minimum compression.
Other features include:
• Working pressures of 1,500, 2,000, or 3,000 psi.
• Nonrestrictive flow through side outlet.
• Flanged or threaded models.
• Slip, mandrel, or threaded suspension.
