Weld Flanges

Product Details:

These welding neck flanges are mainly used on heat coupling of pipes when there is possibility of expansion of the section while bending stress on the coupling.

Product Details:

Weld neck ring joint flanges are designed for use in changing diameters in a piping system. A weld neck ring joint flange comprises a flange with one specified diameter having a bore of a different and smaller, diameter. Except for the bore and hub dimensions, the reducing flange will have dimensions of the larger pipe size. These flanges are used at the outlet side of the expansion joint to increase the size of the flange.

Product Details:

Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications.

Materials used:

• Steel
• Stainless Steels
• Cast Iron
• Brass
• Galvanized steel
• Carbon Steel
• Aluminum
• Copper
• Polypropylene
• PVC etc.

Key Features:

• This is the most common type of high pressure pipe flange.
• They are distinguished from other types of pipe flanges by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe.
• The long tapered hub provides an important reinforcement of the weld neck flange proper in terms of strength and resistance to dishing.

Uses of weld neck flanges:

• The weld neck flange is very resistant to dishing and has a very sturdy connection because it has the pipe along with the tapered hub.
• The flanges are ideal for extreme fluctuations of temperature.
• They are ideal in environments where there may be a lot of bending and handling of the flanges.
• Preferred in an environment with extreme temperature conditions.
• This type of flange is preferred for every severe service condition—resulting from high pressure or from sub-zero or elevated temperature.
• They are used in situations where loading conditions are substantially constant or fluctuate between wide limits.
• This is probably the best welding flange available because of its high, heavy neck.
• Highly recommended wherever a sound welded joint connection is needed.
