Extended Neck Type Tubing hangers are equipped
with a control line (or lines) to control the opening and
closing of sub-surface safety valves (SSSV) from the
surface. These are called 'PTHSCL1' & 'PTHSCL2'.
The type 'PTHSCL1' is equipped with 1 (1/4") hydraulic
control line while 'PTHSCL2' is equipped with 2
hydraulic control lines. Both these types seal the
annulus pressure by compressing the seal with the hold
down screws installed in the type 'PTHS' Tubing spool
top flange.
