Brief description

Neck flange welding is often referred to as a "high pivot" flange. Its purpose is to transfer pressure to the piping, thereby reducing high stress concentrations in the flange base. Neck Flange Welding is a design for butt welding those flanges that provide a structural value in their own right. Our flanges are widely used in petrochemical, process, waterworks, construction, gas and power industries.

Neck butt welding steel pipe flange is commonly known as butt welding flange, English is WELDING NECK FLANGE. Its shape is similar to a flat flange a butt welding bell mouth, but the whole part is a whole, usually called WN flange, which is composed of the first two capital letters according to the full English name. Butt welding flanges are widely used in industry, generally used in medium and high pressure pipelines and equipment, and are currently the most widely used flanges. It is used to match the flange on the equipment (instrument, valve, pump, other equipment, etc.) in the pipeline. The shape of the butt welding flange shows that the position of the butt welding tip has high strength and strong sealing performance. It can be used for medium and high pressure, etc. Pipes or equipment, such as chemical, petroleum, electric power and other high-pressure locations, such as high-pressure, high-temperature, flammable, explosive, toxic, harmful, and highly toxic media can be competent.
