FLANGE
• Connecting pipes and valves are used for the
arrangement of pipes for vapour, air, oil, water,
etc.
• Nominal Pressure
- The ratings of nominal pressures shall be in
accordance with Attached Table.

TYPES OF FLANGES
1. Loose type flanges
• Lap joint type flanges
- The flange to be used in combination with stub end
• Slip-on type flanges
- The flange which is screwed in or inserted into a tube and attached
by welding

TYPES OF FLANGES
2. Integral type flange
- The flange casted or forged integrally with tube
or the flange so welded by complete joint
penetration that the flange and the tube become
integral.
3. Optional type of flange
- The flange attached to the tube by welding.
- This flange must be calculated as the integral
type flange.

Welding Neck Flanges
• The welding neck flange is normally referred to as the
"high hub“ flange. It is designed to transfer stresses to
the pipe, there by reducing high stress concentrations
at the base of the flange. The welding neck flange is
the best designed butt-welded flange of those currently
available because of its inherent structural value. It is
expensive because of the designed
Welding Neck Flanges

Threaded (Screwed) Flanges
• The threaded flange is similar to the slip-on flange, out
the bore is threaded. Its chief merit is that it can be
assembled without welding, explaining its use in low
pressure services at ordinary atmospheric temperatures
and in highly explosive areas where welding create a
hazard.
Threaded(Screwed) Flanges

Blind Flanges
• The blind flange is a flange without a bore. It is used to
close off the ends of a piping system and/or a pressure
vessel opening. It also permits easy access to the
interior of a line or vessel once it has been sealed and
must be reopened.
Blind Flanges

Socket Welding Flanges
• The socket welding flange is similar to a slip-on flange except it
has a bore and a counter bore dimension. The counter bore is
slightly larger than the O.D. of the matching pipe, allowing the pipe
to be inserted into the flange similar to a slip-on flange. The
diameter of the smaller bore is the same as the I.D. of the matching
pipe.
A restriction is built into the bottom of the bore which sets as a
shoulder for the pipe to rest on. This eliminates any restriction in
flow when using a socket welding flange.
Socket Welding Flanges

Flange Types
Semi-Confined Gasket
• Depth of female (recessed) face
normally equal to or less than height of
male (raised) face, to prevent metal-to-
metal contact during gasket compression
• Recessed O.D. normally is not more
than 1/16“ larger than the O.D. of the
male face
• Joint must be pried apart for
disassembly
Unconfined Gasket
• Mating faces of both flanges
are flat
• Gasket may be ring type, or full
face, which covers
the entire face both inside and
outside the bolts

Flange Types
Unconfined Gasket
• Mating face is flat, but the area
inside the bolt holes is raised
1/16" or 1/4"
• Gasket is usually ring type,
entirely within bolts
• Flanges may be disassembled
easily without springing the
flange
Fully Confined Gasket
• Groove depth is equal to or less
than tongue height
• Groove usually not over 1/16"
wider than tongue
• Gasket dimensions will match
tongue dimensions
• Joint must be pried apart for
disassembly

Flange Types
Also Called "API Joint"
• Both flange faces have matching
flat-bottomed grooves with sides
tapered from the vertical at 23°
• Gasket seats on flat section of
flange between bore and ring joint
groove
• Garlock spiral wound gaskets can
replace solid metal ring gaskets
Fully Confined Gasket
• One flange face is flat, the other is
recessed
• For applications requiring accurate
control of gasket compression
• Only resilient gaskets are
recommended - spiral
wound, hollow metal O-ring, pressure-
actuated, and metal-jacketed gaskets

GASKET
• Used for pipe flanges delivering fluids such as
steam, water and oil.

5. Oval Ring Joint

TYPES & TYPE SYMBOLS OF GASKET
• Basic form (A)
- Plate form gasket body alone which has
been made from endless strip of
corrugated thin metal sheet and
overlapped asbestos paper by spot
welding at several points of the metal
sheet at both its initial end and terminal.
• With inner ring (B)
- Basic form equipped with an inner ring.

TYPES & TYPE SYMBOLS OF GASKET
• With outer ring (C)
- Basic from equipped with an
outer ring.
• With inner and outer rings (D)
- Basic form equipped with both
an inner ring and an outer ring.

VALVE
• A valve is a device attached to a pipe or a
tube which controls the flow of air or
liquid through the pipe or tube.
• Valves are provided in a piping system to
regulate or stop the liquid flow.
• Various types exist with their associate
particular function or adventages.

STRAIGHT ANGLE
1. GLOBE /ANGLE VALVE
- A glove valve has a somewhat spherical body enclosing the valve seat and
valve disc.
- The valve disc and seat are a prefect match and may be flat or, more
commonly, mitred.
- Glove valves exist in a right-angled form where the inlet and exit flanges are
at 90º to each other.

2. GATE VALVE
- A gate valve should be fully
open or closed. (it is not
suitable for flow control)
- When open it provides a
clear full-bore internal
passage for the liquid since
the valve or gate is raised
clear.
- The gate may be parallel or
wedge-shaped in section
fitting against a matching
seat.

3. BUTTERFLY VALVE
• A butterfly valve is a type of flow control
device, typically used to regulate a fluid flowing
through a section of pipe.
• The plate has a rod through it connected to a
handle on the outside of the valve. Rotating the
handle turns the plate either parallel or
perpendicular to the flow.

5. NIDDLE VALVE
• A good general purpose needle valve
for fine shots and small beads of
medium viscosity materials.
• The valve is available with stainless
steel wetted chambers suitable for UV
cure dispensing, plastic chambers for
anaerobic dispensing and aluminum
as a standard configuration for
dispensing silicones, grease and
lubricants.

6. CHECK VALVE
• Chest valve or Non-return
valve, allows the fluid to pass
in one direction only.
• Protection of any item of
equipment that can be
affected by reverse flow, such
as flow meters, strainers and
control valves.
• Prevention of flooding,
reverse flow on system
shutdown an flow under
gravity.

7. STORM VALVE
• Scuppers and sanitary discharges as closing appliances.
• Set in the annulus between the drill pipe and the well casing, the
actuator being designed to close the valve upon initial axial
movement of the upper portion of the drill pipe
• Become disengaged from the lower portion of the set drill pipe
allowing the remaining surface suspended drill pipe and
actuator to be retrieved as in the case of a floating drill ship or
set aside for reconnection and reopening of the storm valve after
a storm has passed.

8. QUICK CLOSING VALVE
• Oil tank suction valves are
arranged for rapid closing
from a remote point by the
use of quick-closing valves.

• The insert(valve disc) (1) is placed inside the valve body (6) with the
disc stopper (2) on the left-hand disc, using the ”hook” on the end of
the spanner. The discs are tightened against the valve-seating by
turning the tightening nut (3) towards you. The tightening moment for
the discs depend on the pressure on the discs. To remove insert (1)
with the disc-stopper on left-hand discs, the tightening nut is turned
from you. The “hook” on the end of the spanner is used for lifting
insert (1) out of the valve body. When closing the valve body, the cover
(4) is brought into position and coverbolt-nuts (5) are turned down by
hand, making sure that the cover is planned against the cover-seating.
Turn each coverbolt-nut one half turn at a time until sufficient pressure
is reached. To remove cover (4), loosen coverbolt-nut (5) where the
spring is placed first, then loosen opposite nut. Be sure the jointing is
clear of valve-seating before cover is swing aside. When discs (1) are
inserted in valve-body, cover (4) to be kept open, making it possible to
inspect valve-body for any leakage. When cover (4) is tightened down
and discs (1) are removed from valve-body (6), discs (1) should be
stored as close to the valve as possible, preventing any
misunderstanding whether discs are inside the valve-body or not. The
jointings/gaskets should be inspected before use.

10. HOSE VALVE
• Hose valves have heavy rough brass body with machined brass
vandal-resistant lock shield bonnet and are furnished with a
removable wheel handle.
• Hose valve covering helps prevent damage to delicate tank or
vessel linings, machines, floors, and protects the valve.
• Innovative ball-and-seat design provides a tight shut-off to
minimize leakage.
ANGLE V/V

11. COCK
• Colloquial term for a small valve.

12. HYDRAULIC VALVE
• Diaphragm valve
• Diaphragm valves are used with
low viscosity fluids and are
available in several configurations
for UV cure dispensing, anaerobic
dispensing, cyanoacrylate
dispensing, solvent dispensing
and volatile liquid dispensing.
• Diaphragm valves offer the
highest temperature/pressure
ratings.
