Specification

Types of Weld Neck Flanges

1. Standard Weld Neck Flange

This type of flange is used with butt welding pipe fittings and is an important component of many piping systems. They are suitable for various interface types and different pressure ratings.

2. Long Weld Neck Flanges

Also known as nozzle flanges or “long neck” flanges, these specialty flanges are primarily used in pressure vessel and tank manufacturing. They serve as an all-in-one replacement for standard weld neck flanges and pipe welding combinations.

Applications of Weld Neck Flanges

Weld neck flanges are used in situations where conditions are harsh. Some common situations include:

1. High pressure systems

2. Wide temperature and pressure fluctuations

3. High temperature environments

4. Handling volatile and hazardous liquids

5. Working in extremely cold conditions

Due to their rugged construction and excellent stress distribution capabilities, these flanges are able to handle such challenging conditions.
