Weld-Neck Flanges

Weld neck flanges, also known as high-neck flanges, consist of a flange and a long neck section. The long neck section is connected to the pipeline using a full-penetration weld. Bolt holes are evenly distributed on the flange, and the bolts, along with the mating flange, compress the sealing gasket to achieve a rigid connection and seal. The neck design not only enhances the flange's load-bearing strength but also effectively disperses welding stress, preventing connection failure due to stress concentration. Compared to other types of flanges, such as slip-on flanges, they are more suitable for long-term use under high-pressure conditions.

Petrochemical Industry: Weld neck flanges are core connectors in petrochemical pipeline systems, widely used in crude oil extraction, refining, and chemical synthesis.

Energy and Power Industry: Suitable for pipeline systems in thermal power, nuclear power, and wind power projects. In thermal power, they are used to connect boiler steam pipes and turbine inlet and outlet pipes, withstanding long-term erosion from high-temperature, high-pressure steam.

Marine Engineering: Widely used in offshore drilling platforms, subsea oil pipelines, and marine propulsion systems.

Municipal and industrial infrastructure: Used in scenarios such as high-pressure natural gas transmission pipelines in cities, high-pressure sludge transmission pipelines in sewage treatment plants, and blast furnace gas pipelines in steel plants.
