5. 5
Tubing Hanger
▪ Tubing hanger is used to hang the tubing from within the tubing head
by means of a thread.
▪ These load-bearing devices are installed in the top bowl of the tubing
head and are run through the BOP. Also doubling as a means to
access and manipulate additional smaller tubing lines that are utilized
down hole and extended to the surface on the outside of the tubing
string(s).
▪ Available for any type of single/multiple completion, most tubing
hangers accept a BPV that seals the tubing bore. Some hangers are
ported for hydraulic control lines, SSSV’s, or other types of completion
equipment.
▪ Sealing type can be rubber seal and metal seal.
Tubing Head Adapter
▪ A connection between the wellhead and the tree, the
adapter hangs no load nor provide a controlled seal bore.
▪ The smooth seal bore on a tubing head is used when
tubing is suspended from the tubing hanger
▪ For low-pressure completions, these tubing hangers are
not designed for tubing string manipulation or control lines.
▪ It is often installed along with X-mass tree after tubing.
Tubing Head
▪ Complies with API 6A Specifications.
▪ Tubing head is an equipment attached to the casing spool used to
hang the tubing (smallest casing string) and seal the annulus
between the tubing and casing. It is mainly consisted with tubing
spool, tubing hanger, lockdown screw parts etc.
▪ Sealing type can be rubber seal and metal seal.
▪ On the bottom of casing head, designed with injection valve and
test pressure valve, in order to injection sealing grease and do
pressure testing on the sealing system.
6. 6
Casing Head
▪ Complies with API 6A Specifications.
▪ Has single, dual and triple configurations available.
▪ Adapts to HPHT applications.
▪ Is designed for H2S service if required.
▪ Is designed to operate up to 20,000psi WP.
▪ Is manufactured in as-required temperature/material classes, PR & PSL..
▪ Comes with wear bushing assembly, bowl protector running and retrieving tools, and
BOP testers if needed.
Casing Hanger
▪ Complies with API 6A Specifications.
▪ Fits standard wellheads.
▪ Easily engaging and latching cap screws enable quick installation.
▪ Meets a multitude of needs to suit your specific operation.
▪ Suitable for high H2S, chlorides, and HP/HT.
Casing Spool
▪ This straight-bowl casing spool eliminates the need for lockdown
screws to retain the bowl protector, creating fewer leak paths
than other standard casing spools and prevents wedge-locking of
pressure-energized parts (hangers, test plugs).
▪ Threaded, studded, or flanged outlets can be machined to
access the annulus, depending on your well.
▪ Bottom prep options range from metal seals to proprietary non-
metallic seals, also determined by your well conditions and
requirements.
7. 7
Parallel Expanding Type
This unidirectional expanding gate gives an extraordinarily high mechanical seating seal
force that acts simultaneously against both seats. The seating force is not affected by line
pressure fluctuations or vibrations.
Gate Valve
▪ Complies with API 6A Specifications.
▪ Adapts to HPHT applications.
▪ Is designed for H2S service if required.
▪ Is designed to operate up to 20,000psi WP.
▪ Is manufactured in as-required temperature/material classes, PR & PSL.
▪ Is hand wheel operated or pneumatically or hydraulically actuated.
Solid Slab Type
This design is made for demanding applications such as high pressure critical service choke
and kill manifolds, and as a safety shut-off valve operated by a hydraulic or pneumatic
actuator. Its bidirectional design with a floating gate moves parallel to the seats and effects a
tight seal under differential line pressure. The non-rising stem has a back-seating feature
that allows the stem bearings or packing to be replaced under pressure.
Split Type
This bidirectional valve features a metal-to-metal seal between gates and seats, and seats to
body. Sealing is enhanced by an auto-seal system in which internal body pressure transmits
sealing compound from reservoirs in the seats to grooves around the seat bore, thus
preventing leaks. The parallel non-wedging gates allow the stem to be left unstressed
in either the open or closed position. Fully-skirted seats provide continuous protection of
gate sealing surfaces. A back-seating feature allows replacement of stem bearings or
packing under pressure.
8. 8
Positive Choke Valve
▪ Ceramic or hard alloy types are available.
▪ High abrasion resistance, high temp resistance, high corrosion
resistance, and long life time.
▪ Metal to metal sealing design enables good performance reliability.
Adjustable Choke Valve
▪ Special high corrosion material and technology are employed for
stem and seat.
▪ High abrasion resistance, high corrosion resistance, and long life time.
▪ Pressure balanced sealing ring at external sleeve reduces switch
torque.
▪ Design of lock on external sleeve ensures stability.
Check Valve
▪ Hwayoo check valves are used to isolate pressure pumping
equipment from high-pressure treating fluids during fracturing
applications.
▪ Offered in three primary models, these rugged valves seal against a
complete range of pressure pumping fluids at pressures up to 20,000
psi CWP. Valves are available in 1½ to 4 inch bore sizes for standard
and reverse flow applications.
▪ Sour gas models are available.

Surface Safety Valve
Hwayoo Surface Safety Solutions provide our clients with fail-safe surface safety valves
(SSV) and reliable control panels for standard and demanding operations, such as
production, well intervention and stimulation.
Our safety valves are hydraulically or pneumatically actuated gate valves. The actuators,
either hydraulic or pneumatic, are designed and manufactured for simplicity, ease of
maintenance and adaptability in compliance with API 6A specifications and as required for
different applications of size, stroke and force.
Hydraulic Actuator
Hydraulic Actuator is a ratio-piston-type actuator mounted on a reverse-
acting gate valve. It is designed to be fail-safe and fail-close. When
installed as part of a safety system, it will automatically close with the
loss of control pressure and will open automatically when the control
pressure is restored.
Pneumatic Piston Actuator
Pneumatic Piston Actuator is a ratio-piston-type actuator mounted on a
reverse-acting gate valve. It is designed to be failsafe and fail-close.
When installed as part of a safety system, it will automatically close with
the loss of control pressure and will open automatically when the control
pressure is restored.
Control Panel
▪ Sequential valve opening and closing
▪ Monitor flow line pressure status
▪ Emergency shutdown (ESD)
▪ Manual override
▪ Any combination of hydraulic/pneumatic valve actuator
controls
▪ Remote telemetry control
▪ Fire safety shutdown
▪ Easy serviceability
▪ Corrosion resistant type 316 stainless steel
(SS)Intrinsically safe to meet requirements such as U. L.,
CENELEC, BASEEFA, C. S. A. and others
▪ Standard Single Wellhead Control Panel & Multi-
Wellhead Control Panels are available.

requirements, but we make sure they accommodate standard and
custom stroke lengths. All tools and accessories, such as BPV, VR
plugs, two-way check valves and hand tools, are available for API 6A
equipment.
The lubricator assembly consists of a lubricator, a VR plug or a BPV
(optional) and a Parmelee friction wrench, etc.
