4 inch SPECTACLE BLIND FLANGES

SPECTACLE BLIND FLANGES

Description of flanges in general:

It is the second most used joining method for jointing after welding in pipes.

Flanges connect the pipe to various equipment and valves.

Provides flexibility for maintenance and easy access for cleaning, checking or adjusting.

Flanges are usually welded or screwed.

Different types of ends are used to connect the flange to the pipes according to the design requirements

Mainly used in the fields of water system, industrial machinery, vehicles and ships, architecture and decoration, etc.

There are different types of flanges:

Types of flanges

• Weld neck flange
• sliding flange
• Socket weld flange
• lap joint flange
• threaded flange
• blind flange

• Long life

Materials made from it:

Flanges are made from different materials such as stainless steel, cast iron, aluminum, brass, stainless steel etc. but the most commonly used material is stainless steel and they have machined surfaces.

In addition, flanges, like fittings and pipes, are sometimes internally fitted with layers of material of very different quality, which are “cushioned edges” for specific purposes.

The material of the flanges is mainly decided during the selection of the pipe, and in most cases, the flange is of the same material as the pipe.

 Flanges are mainly used for connections of pipes, valves and equipment that require frequent maintenance.

Materials

• Stainless steel

Spectacle Blind

• Material: stainless steel, carbon steel, alloy steel and stainless steel.
• Type: blind
• Petrochemical and gas industry, shipbuilding industry, energy industry, valve industry, water works, and general pipe connecting projects.
• It operates as a single bond or an annular spacer.
•  A piece of metal cut to fit between two flanges of a pipe and usually sandwiched between two flanges
• The spectacle curtain is often made of two metal disks connected to each other by a small steel section.
• It looks like a pair of glasses
•  One end of the flange has a hole to allow flow through the pipe during operation and the other end is solid to prevent flow during maintenance.
• They are generally installed as a permanent device to separate the process piping system.

The whole idea of ​​the blind flange

is that one can be absolutely certain that an item of equipment has been properly and safely emptied with no possibility of any overflow or leakage through a valve during maintenance.

The flow can be diverted to other items of equipment but not just by passing it around the vacuum as this would compromise the safety function of the spectacle curtain.

The flow must separate from the valve and relieve pressure before loosening the screws

product specification:

• Corrosion resistant
• Accurate dimensions
• It can bear high pressure and temperature load
• Rust resistance
• Smooth transition from flanges to tube thickness
• Ensure excellent pressure distribution
