Slide 12

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

Slide 13

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 tothe pipe, there by reducing high stress concentrationsat the base of the flange. The welding neck flange isthe best designed butt-welded flange of those currentlyavailable because of its inherent structural value. It isexpensive because of the designed

Welding Neck Flanges

Slide 19

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

Slide 20

Blind Flanges

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

Blind Flanges

Slide 21

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

Slide 22

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 coversthe entire face both inside and outside the bolts

Slide 23

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

Slide 24

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 - spiralwound, hollow metal O-ring, pressure-actuated, and metal-jacketed gaskets

Slide 25

GASKET

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

1. Flat Nom-Metallie and Metal Clad or Jacketed Gaskets

2. Spiral Wound Gaskets

GASKET

Slide 27

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.

Slide 28

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.

Slide 29

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.

Slide 32

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.

Slide 33

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.

8. QUICK CLOSING VALVE• Oil tank suction valves are

arranged for rapid closing from a remote point by the use of quick-closing valves.

Slide 44

9. SEUT VALVE

Slide 45

• 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.

Slide 46

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.
