Frac Heads
WELLSITE SERVICES COMPANY
Description:
Stinger Wellhead Protection’s frac heads are designed to replace the existing lower pressured production wellheads with
higher rated multi valve wellheads during fracturing treatments.
Specifications:
Stinger offers two types of assemblies: the Special Pin Assembly and the Screw-on Assembly.
Available in full bore:
77.8 mm (3 1/16 in.) x 69 MPa (10,000 psi) or
103.5 MPa (15,000 psi) working pressure.
103.5 mm (4 1/16 in.) x 69 MPa (10,000 psi) or
103.5 MPa (15,000 psi) working pressure.
Special Pin Assembly
The special pin assembly adapts to both
flush mount or extended neck tubing
hangers. The bonnet incorporates
a positive sealing system. The seals
are energized and pressure tested to
69 MPa (10,000 psi) prior to the frac
treatment. Running a back pressure
valve or a tubing plug allows the special
pin assembly to be safely installed and
removed by a Stinger crane unit without
the assistance of a service rig.
Screw-On Assembly
Screws directly on tubing after packer
is set in tension. Can be flanged on
to BOPs or tubing spool for multiple
zone access. Available in various pipe
connections (EUE, VAM, and Hydril).
