Separating one part of a line from another requires a spectacle blind, able to switch from closed to open and back again. Bleed rings provide a means to release pressure from the pipe through a controlled opening.

Materials used:

Stainless Steel:ASTM A182 F304/304L, F316/316L, F316H, F316Ti, F321, F44(UNS S31254)

Key Features:
Can be attached to the pipe without welding (sometimes an additional seal weld is used as well) Ideal for higher pressure and temperature applications for small pipe sizesNot recommended for larger loads, especially when subjected to higher torque

Uses of threaded flanges:Threaded flanges can be fitted to pipes of various sizes without welding and this is one chief benefit for which these flanges are highly demanded.They can be used in extremely high pressure applications, particularly at or near atmospheric temperature, where the necessary post weld heat treatment is not possible.They are ideal for small diameter piping applications.They are economical and time saving devices.These threaded flanges are normally designed for non-cyclic applications.The flanges are suitable to be used in applications where welding is hazardous.They can be used in highly explosive areas.These types of flanges are made from plate, and come in 3 different types.

The first and most widely used type are spec blinds short for spectacle: these are flanges with two equal outside diameter (OD) parts welded together by way of a bridge. One of the parts also contains an inside diameter (ID), while the other is a blank, or blind. A whole is put at the halfway mark of the bridge. These are also called spectacles, figure 8s, and figure 8 blanks, because of their resemblance to reading glasses (spectacles) and figure 8s. These are referred to as Line Blanks in the ASME/ANSI standards.

The second and third types are quite similar: both have longer bridges, referred to as paddles, which resemble longer handles. One type has only an OD, and so is a blind plate similar in appearance to a large pizza oven peel. These are referred to as paddle blinds. The other type is exactly the same but comes with an ID as well, enabling flow-through when installed in a piping system. These pieces have holes in the paddle which enables field personnel to determine by sight which piece is installed in a system. These are referred to as paddle spacers, and are often supplied in sets together with the paddle blinds.

All 3 types of these flanges are used in piping systems or pressure vessels where the flow needs to be interrupted from time to time. They are installed between two pipe flanges (as specified above), and by way of a screw inserted into the hole in the bridge or paddle, they are able to rotate or swing into and out of position to interrupt or allow the flow, as the user sees fit.

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.

Key Features:
The recess on the inside diameter of the socket weld flange allows for a good fit of the pipe allowing for a smooth flow of liquid. Socket welding flanges work well for smaller sizes and higher pressure temperature conditions. They are similar to slip-on flanges, but must specify the schedule of the pipe where they will be used for with socket welds.

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.

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.

Advantages of Lap Joint Flanges:Lap Joint flanges have certain special advantages over other flanges. These are as follows:Lap Joint flanges have the freedom to swivel around the pipe. This facilitates the lining up of opposing flange bolt holes.Lack of contact with the fluid inside the pipe leads to the greater durability of these flanges.In piping systems which corrode or erode quickly, the lap joint flanges may be salvaged for re-use.The pressure-holding capacity of lap joint flanges is little. But it is better than that of slip-on flanges.The Lap Joint works as a backing ring on the stub.The main advantage of lap joint flange is that the bolt holes can be aligned with the matching flange after the welds have been completed.They allow rotational alignment capability.

As the mainstay of our business, we are dedicated to providing our customers with all possible options of flanges in a wide variety of steel, chrome, and nickel alloys.Pipe Flanges are widely used as a popular category of pipe fittings. A flange is used to mechanically connect two pipes together. It can also be used to mechanically connect a pipe to a tee, valve, choke or any other piece of equipment. Flanges are available in round, square, and rectangular shapes. In some cases, flanges are usually in the shape of a ring or a plate to form a rim at the end of a pipe when fastened to the pipe. This is an example of closet flange.A flange can also be a plate for covering or closing the end of a pipe. This is a blind flange. Thus, flanges are considered to be projecting or internal components which are used to support mechanical parts. They are like rims which are used to strengthen the mechanical part or they are a means of attaching that part to another part or surface.

Uses of pipe flanges:Flanges are used for variety of purposes. The main purpose is to connect pipes but they are also used for connecting other equipments. Flanges are fit to a variety of other components besides pipes. They are fitted to bellows, ducts, wheels, and cameras. We give below the various uses of pipe flanges:Flanges are also placed on beams to provide additional strength.They prevent the beam from failing.They are used for guide, as the flange of a train wheel.Flanges are used for attachment to another object like for example, the flange on the end of a pipe, steam cylinder, etc.They are fixed on the lens mount of a camera.A flanged rail is a type of rail with a flange on one side to keep wheels from running off.

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.
