BLIND FLANGES

The Blind Flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction.

Features of blind flanges:
Some important features of blind flanges are as follows:
Blind flanges are sometimes supplied with NPT fittings which allow pressure test connections to be fitted.
They are used to blank off the ends of pipe.
They are also used to blank off the ends of valves and pressure vessel opening.
Considering factors like internal pressure and bolt loading, blind flanges, especially in the larger sizes, are the most highly stressed of all types of flanges.
Since the maximum stresses in a blind flange are bending stresses at the center, they can safely be allowed to be higher than in other types of flanges
Blind flanges are made to fit standard pipes in all sizes..

General notes:

Dimensions are in millimeters unless otherwise indicated.
D = Hole size (where required) should be the same as the flange bolt hole. In practice, these dimensions have been rounded round off upwards.
Wt = Thickness of the web (or tie bar) should be 6 mm minimum, or equal to Thickness (t) if less than 6 mm.
Spectacle Blinds Flanges should be made from a plate or forging specification, approved for use by ASME B31.3, of essentially the same chemical composition as the mating flanges and piping involved.
Spectacle Blinds Flanges according to ASME B16.48 may be used for installation between ASME B16.5 flanges
Depending on a customer specification, some dimensions can be different from what on this page is defined.

ORIFICE FLANGES

ORIFICE FLANGES are widely used in conjunction with orifice meters for measuring the rate of flow of liquids and gases. They are basically the same as standard welding neck and slip-on flanges except for the provision of radial, tapped holes in the flange ring for meter connections and additional bolts to act as jack screws to facilitate separating the flanges for inspection or replacement of the orifice plate. In choosing the type of orifice flange, the considerations affecting the choice of welding neck and slip-on standard flanges apply with equal force.

Uses of orifice flanges:

Orifice flange is used to flow/rate metering of piping systems.
They are used for all intensive purposes, similar to weld neck and slip-on flanges with extra machining.

SLIP ON FLANGES

A Slip-On Flange is bored sightly larger than the outer Diameter of the matching pipe. The pipe slip into the flange prior to welding both inside and outside to prevent leaks.The British standard flanges manufactured by us pertain to all Standards like BS10 1962 Table D,E,F,H IS 6392 Table 5,17,26 IS 1538 in slip. These are manufactured using mild steel both in slip-on and blind type. Our quality slip on flanges are ideal for lower pressure applications. Their ease of fitting and welding reduces fabrication costs. Our professional engineering team is involved in innovating durable and high-quality products to cater to our clients’ needs.

The flange is slipped over the pipe and then welded both inside and outside to provide sufficient Strength and prevent leakage. This flange is used in preference to weld necks by many users because of its lower cost and the fact that less accuracy is required when cutting pipe to length.

Sizes for Slip On Flanges
All Slip On Flanges are available available in sizes from 1/4” through to any size.

SOCKET WELD FLANGES

Socket welding flange, a popular type of pipe flange, was initially developed for use on small-sized high- pressure piping. The fabrication of this type of flange is similar to that of a slip-on flange. However, the internal pocket of a socket weld flange allows for a smooth bore and better fluid flow. When provided with an internal weld, the static strength of this flange is equal to slip-on flange, but the fatigue strength is 50% greater than double welding slip-on flanges. Smooth bore conditions in such a flange can easily be attained without having to bevel the flange face and, after welding, to re-face the socket weld flange as would be required with slip-on flanges. For this reason, the internally welded flange is popular in chemical process piping. The counter bore is sightly larger than the Outer Diameter of the matching pipe, allowing the pipe to be inserted. A restriction is built into the bottom of the bore, which acts as a shoulder for the pipe to rest on, and has the same I.D. of matching pipe. The flow is not restricted in any direction.

LAP JOINT FLANGES

Lap Joint flanges are used on piping fitted with with lapped pipe or with lap joint stub ends. The lap joint flange with the stub end assembly are normally used in systems requiring frequent dismantling for inspection and cleaning and where the ability to swivel flanges and to align bolt holes materially eases the erection of large diameter or unusually stiff piping. These flanges are also used in applications where there is a need to facilitate bolt alignment. These type of flanges are similar to slip-on flanges. The only difference is that it has a curved radius at the bore and face to accommodate a lap joint stub end. They may be used at all pressures and are available in a full size range. These lap joint flanges slip over the pipe, and are not welded. They are otherwise fastened to it. Here the bolting pressure is transferred to the gasket by the pressure of the flange against the back of the pipe lap.

THREADED FLANGS

Threaded Flanges are confined to special applications. Their chief merit lies in the fact that they can be assembled without welding this explains their use in extremely high pressure services, particularly at or near atmospheric temperature, when alloy steel is essential for strength and where the necessary post weld heat treatment is impractical. Threaded Flanges are unsuited for conditions involving temperature or bending stresses of any magnitude, particularly under cyclic conditions, where leakage through the threads may occur in relatively few cycles of heating or stress; sea welding is sometimes employed to overcome this, but cannot be considered as entirely satisfaction.

SPADES & RING SPACERS

Spades and Ring Spacers are basically the same as Spectacle Blinds, except that both are not attached to each other.
Spades and Spacers be applied in systems where maintenance is often not necessary, or in applications with large pipe sizes. Spectacle Blinds, Spades and Ring Spacers should be made from a plate or forging specification, approved for use by ASME B31.3, of essentially the same chemical composition as the mating flanges and piping involved.
