A spectacle blind flange is a safety device used to isolate a section of pipeline or equipment when they need to be inspected or removed from piping system. It is not like a valve, the spectacle blind flange is a permanent or long term isolation block. The spectacle blind flange is made of two pieces metal discs which are joint together by a part of steel handle. The two discs are connected by a hinge, so that the blind flange can be rotated to open or close the pipeline. Technical Specifications a. Material: Carbon steel, stainless steel, alloy steel b.

This is similar to a slip-on Flange in outline, but the bore is counter- bored to accept the pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The Flange is attached to the pipe by a fillet weld around the hub of the Flange. An optional internal weld may be applied in high stress applications. Its biggest use is in high-pressure systems such as hydraulic and steam lines.

The Flange is slipped over the pipe or tube and welded (usually both inside and outside) to provide strength and to prevent leaks. These flanges are at the low cost end of the scale, and do not require high accuracy when cutting the pipe or tube to length. They can sometimes have a boss or hub, and can be made with a bore to suit pipe or tube.

This is similar to the slip-on Flange in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. The Flange may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing its use in pressure applications.

This Flange is designed to be joined to a piping system by butt- welding. It is relatively expensive because of its long neck, but is preferred for high stress applications. The neck transmits stresses to the pipe, reducing stress concentrations at the base of the Flange. The gradual transition of thickness from the base to the neck to the wall thickness at the butt weld provides important reinforcement of the Flange. The bore of the Flange matches the bore of the pipe, reducing turbulence and erosion.

Lap Joint flanges are used on piping fitted 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.

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.

CS ASTM B16.5 Flanges
Flanges are piping components bolted together using gasket in between two flanges as a sealing material. Flanges are used to connect pipes with each other, connect pipes to flanged valves, connect pipes to flanged fittings, connect pipes to flanged piping specialty items such as strainers and to isolate piping sections using a blind flange.A flange is designed to connect sections of pipe to join them to an assembly such as a pressure vessel, valve or any equipment. Flanges are joined by bolting, and sealing is completed with the use of gaskets and other sealing methods like spray guards or specific spray flanges
Flanges, all type and size flanges manufacturers.
A flange nut looks like a standard hex nut from one side, but the bottom is widened into a circular flange, creating a bell-like shape. Most of the time manufacturers serrate the bearing surface of flange nuts So that it gives a better grip on the surface of the joint. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. The flange may be serrated to provide a locking action. On a serrated flange nut, the serrations are angled such that they keep the nut from rotating in the direction that would loosen the nut. Because of the serrations, they cannot be used with a washer or on surfaces that must not be scratched. Flange nuts are widely used in automobiles, electronic products, and the aerospace industry. HELLARY offers these nuts mostly hexagonal in shape and are made up of hardened steel and often coated with zinc.
