Weld neck flanges are the most popular flange type with a neck extension with a weld bevel at the end. This type of flange is designed to butt weld directly to pipe to provide a superior and relatively natural form connection. In larger sizes and higher pressure classes, this is almost exclusively the type of flange connection utilized.

EN / BS weld-neck flange (WN flange) features a hub whose size matches the pipe for butt welding, so the stress is transferred from the flange to the pipe. It is mainly used for high pressure and temperature applications. Available size for PN 16. Size Flange OD D(mm) Bolting (No.x hole) Ref. /2″ / DN15 / 21.3mm: 95:

Weld neck flanges are the most popular flange type with a neck extension with a weld bevel at the end. This type of flange is designed to butt weld directly 

Weld Neck Flange is flanges that designed to be joined to a piping system by butt welding. This kind of flange include lots of specification.

The welding neck flange is normally referred to as the "high hup" flange. It is designed to transfer stresses to the pipe , thereby reducing high stress concentrations at the base of the flange . The welding neck flanges is the best designed butt welded flange of those currently available because of its inherent structural value.

A typical weld neck flange has a weld prep at the tip of the neck to weld up to matching pipe, whereas long weld neck flanges, or "nozzles," are square cut at the ends for the purpose of

Weld neck flange (WN flange) has a neck that can relocated stress of the pipe, so to reduce the pressure that gathered in the flange bottom. It is compatible to the pipelines that works in high or low temperature and bear high pressure. Specially for the pipe or the valves when PN is larger than 2.5 Mpa. Our Supply Range

The stainless steel welding neck flanges DIN /PN25 are attached by welding to the pipe to the neck of the flange. This transfers stress from the flange to the

Weld Neck flanges are the most popular flange type with a neck extension that has a weld bevel at the end. It is designed to be butt weld directly to the pipe to provide a superior and relatively natural form connection. Flange is relatively expensive because of its long neck, but is preferred for high stress applications.
