Subject: Operation and Maintenance of Choke Manifold
INTRODUCTION
The floor choke manifold consists of seven manual valves. It used to control
the follow rate and reduce well pressure before the flow enters the
processing equipments. These also include a variable choke box, a fix choke
box, and several pressure and sampling ports and thermo well to monitor
pressure, temp. and fluid characteristics.
These design allows the well to flow through calibrated chokes for flow rate
reference, as well as through adjustable chokes. The well can also be placed
in a shut-in condition if required. Dual flow path allow fast choke changes
without interrupting the flow. Fixed chokes can be installed in both flow paths
if necessary.
Well parameter can be monitored by pressure gauges, temperature gauges

and recorders. Reservoir behavior can be monitored at the choke manifold by
installing pressure and temp. Gauges. Combining these data with flow rates
measurement and reservoir fluid properties provide a way to characterize
well performance.
A number of models and sizes are available for different well pressures,
temps. and flow raters. The manifold rates w.p. 69 MPa (10000 psi.) is
typically equipped with standard hammer union, but they can be fitted with
other connections, such as API-6A & Grayloc flanges.

SUBJECT: OPERATION AND MAINTENANCE OF SLAB MODEL GATE VALVE.
INTRODUCTION
Parveen products assures you of dependable valve which will give you years of
trouble free service with a minimum care and maintenance. The manual prepared to
assist our valve owner in the installation, operation and routine maintenance of
Parveen valves. Further any special instruction, assistance or service please write
or call our factory, our nearest representative. This manual applies only for Parveen
model- slab gate valve.
These valves are bi-directional-slab-gate type with pressure-actuated seats features:
x Full bore through conduit

x Bleed and block mechanism
x Long life floating seat with self-relief function
x In line maintenance
x Metal to metal sealing between gate – seat
x Metal to metal stem back seat
x Low torque for easy operation
x Non rising and non balanced stem
x Forged body and bonnet construction
INSTALLATION INSTRUCTIONS: -
All the valves are supplied in a ready but should be inspected for loose or damage
during transportation. Valve must be in opened before installing and hydro-testing
valves should be thoroughly drained to eliminate water on other test fluid from body.
OPERATION OF SLAB MODEL VALVE:-

This valve has two floating seats, each consisting of a steel ring with an elastomer
ring. in its back .
When hand wheel rotated in clockwise direction the gate moves across the conduit
openings. The floating action of the gate and seat makes a total pressure actuated
seal, which holds tight both upstream and downstream pressure. Because of this
pressure-actuated type of seal, it is not necessary to close or open the model-t valve
hard to affect a tight seal. In case of very low pressure differential in slab model
valve, it is advantageous to back off on turn from full open on full closed position to
allow the gate and seats to float freely and effect a tighten sealing.

CHOKE AND KILL MANIFOLD
PARVEEN fabricates custom designed choke

and kill manifold :
1) In oil / gas well drilling operation, drilling fluids
(Muds) of designed gravity are used to
overcome sub-surface pressure or the influx of
formation fluid. On some occasion, kicks are
experienced with change of pressure of
formation while drilling. This is necessary to
build up drilling fluid density to prevent influx of
formation fluid. The Choke and Kill Manifold
allows the driller to regulate back-pressure on
Choke Manifold
the formation while gradually density of the
drilling fluid is built up by circulation with closed
B.O.P., till the well is stabilized and drilling is
resumed.
The Choke and Kill Manifold are available up to

10,000 PSI in sizes of 2” to 3” for standard and
sour services. Other type of Manifold (stand
pipe, cementing etc.) can also be made
available.
2) For well Testing / Completion / Intervention,

Industry uses varies configuration of Manifold,
as per requirement of Service / Operating
Companies, PARVEEN designs and fabricates Eruption Manifold
custom made manifold in sizes of 2” to 3” up to
10,000 PSI for standard and sour services for
following application.
(a) Choke Manifold For flow back/work over

(b) Production Manifold for diverting flow
through test separator or vent or burner.
(c) Gas Manifold for Diverting gas through
orifice meter or burner.
(d) Data Recorder for recording flowing
pressure and temperature.
(e) Stimulation / Treatment for Well
stimulation/treatment service.

General Note:
a. Bolting material will not be used beyond temperature limits specified in the governing Code.
Notes:
1. Repair welding of bolting material is prohibited.
2. These bolting materials may be used with all listed materials and gaskets.
3. These bolting materials may be used with all listed materials and gaskets, provided it has been verified that as
Sealed Joint can be maintained under rated working pressure and temperature.
4. These bolting materials may be used with all listed materials but are limited to class 150 and class 300 Joints.
5. These materials may be used as bolting with comparable nickel and special alloy parts.
6. This austenitic stainless material has been carbide solution treated but not strain hardened. Use A 194 Nuts of
corresponding material.
7. Nut may be machined from the same material or may be of a compatible grade of ASTM A194.
8. Maximum operating temperature is arbitrarily set at 5000 F (2600 C) because hard temper adversely affects design
stress in the creep rupture range.
9. Forging quality not permitted unless the producer last heating or working these parts tests them as required for other
permitted conditions in the same specification and certifies their final tensile, yield, and elongation properties to
equal or exceed the requirements for one of the other permitted conditions.
10. This ferritic material is intended for low temperature service. Use A 194 Gr 4 or Gr 7 nuts.
11. This austenitic stainless material has been carbide solution treated and strain hardened. Use A 194 nuts of
