Blind Flanges Dealers in Ahmedabad

Spectacle Blind   These types of flanges are made from plate, and come in three 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 hole is put at the halfway mark of the bridge. These are also called spectacles, figure 8’s, and figure and blanks, because of their resemblance to reading glasses (spectacles) and figure 8’s. 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 a 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.Our spec blind flanges are available with raised, flat, or RTJ faces.These flanges are available in all of our stainless steel and chrome-moly grades, from ½” to 24” and beyond, class 150 to 2500. We can also source many of your other grade requirements.

Normally referred as blanking flanges, Blind flanges are widely used in high pressure applications. Blind flanges are generally used to seal the end of the piping system to prevent flow of fluid. The use of blind flanges allows easy of access to piping system once it has been closed. Blind flanges are widely being used in shipbuilding, power generation, petrochemical plant, water treatment, dairy plant, pharmaceutical plant etc.Standards: ASME B.16.5, ASME B.16.47 (A/B Series), B16.48-API590, API 605, AWWA C207, BS 10, DIN 2633, MSS-SP-44.Classes: 150 lbs up to 2500 lbsSizes: 1/2"up to 36" (Sizes over 36" available on request)Materials: Monel, Nickel, Inconel, Hastalloy, Titanium, Tantalum, Stainless Steel, Alloy Steel, Carbon Steel, Cupro-Nickel 90/10 & 70/30Joint faces: RF/RTJ/FF

Blind Flanges are used in quick assembly to save the cost. These are blank flanges and have no bore. We provide wide range of Blind flanges that are designed as per the international standards of ASTM, ASME, API, AISI, BS, ANSI, DIN, JIS, MSSP and NACE. We also provide these flanges with mill test certificate as per EN 10204 3.1B.

BLIND FLANGES are used to blank off the ends of piping, valves and pressure vessel opening. From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed of all flange types; however, since the maximum stresses in a blind flange are bending stresses at the center, they can safely be permitted to be higher than in other types of flanges.  

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.
