Product Description

Huazhan Steel Weld Neck Flange

Product Description

A weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange. There are two welding neck flanges designs -the first type is used with wipes while the second, longer type cannot be used with pipes but with a process plant. The weld neck flange comprises of a round fitting that extends beyond the rim of the circumference. These flanges, typically manufactured from forging, are actually welded to pipes.

The rim has numerous holes drilled into it that enables the flanged to be attached to a bolted flange. This design is far better because of the structural valve.

Characteristics of welding neck flanges:

These flanges are distinguished by having a long conical neck, the end of which is welded to the connecting pipe. The inside diameter of the pipe is equal to that of the flange, providing a conduit of generally constant cross-section and no interruptions or turbulence in the gases/liquids flowing through the pipe. Welding neck flanges provide high load strength along with even stress distribution.
Attention must be paid to the junction between the flange and the pipe to be welded on in order to avoid possible interruptions in high speed flows.

Why use a welding neck flange?
WN flanges are intended for activities involving high pressure and extreme conditions (cold or heat), flammable or corrosive contents, etc., and, above all, environments where leakage must be minimal or almost non-existent. They are used in order to  minimize the number of welds on small parts while helping to reduce corrosion of the junction itself.

They are used in steam lines; oil, natural gas and refined hydrocarbon lines; fire networks; petrochemical facilities, etc.
