4 inches Welding Neck Flanges

Welding Neck 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

Welding Neck Flanges

It is used for operation at high temperatures and high pressure or if there are large fluctuations in pressure and temperature.

These flanges are useful in handling costly, hazardous, flammable and explosive liquids, because failure or leakage of a flange connection can be disastrous to the plant.

Stainless steel flanges for pipe fittings and piping systems provide a natural shaped connection ideal for large, high pressure applications.

Materials made from it:

Flanges are made from different materials like stainless steel, cast iron, aluminium, brass, bronze etc. but the most commonly used material is forged carbon steel and they have machined surfaces.

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

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

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

Materials

• carbon steel
• Low temperature carbon steel
• High yield carbon steel
• stainless steel

The whole idea of ​​the flancha

Weld neck flange (WN flange) has a neck that can change the pressure position of the pipe, so as to reduce the pressure gathered at the bottom of the flange.

It is compatible with pipelines operating at high or low temperatures and withstanding high pressure.

Especially for pipe or valves when the PN is greater than 2.5 MPa.

Weld neck flange has two shapes (two shapes), one with a reduced neck ( reduce weld neck flange ) and the other with a typical long neck called long neck weld flange.

product specification:

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