Product Introduction

Welding neck flange is a common flange connection method, which is to weld the flange neck to the pipe, and then connect the two flanges together by bolts. The following is a detailed introduction of the neck butt welding flange: Welding neck flanges usually consist of a flange body, neck and welding parts. The flange body is generally made of carbon steel, stainless steel and other materials, the neck is the intermediate connecting part between the flange body and the pipe, and the welding part is the area where the neck and the pipe are welded together. Size The ASME B16.47 standard is mainly for large diameter flanges, with common sizes ranging from 22 inches to 48 inches, amount to DN550-DN1200. Pressure Level The pressure rating of the weld neck flange is also determined according to the working pressure of the pipeline. Common pressure levels are 150 pounds, 300 pounds, 600 pounds, 900 pounds. How to use The use of the weld neck flange is very simple, first weld the neck of the flange to the pipe, and then connect the other flange to the other end of the pipe. When connecting, use bolts to connect the two flanges together, and gaskets can be used to ensure the leakproof connection. Applications Welding neck flanges are widely used in petrochemical, shipbuilding, shipbuilding, electric power, water treatment, pharmaceutical, food and other industries. Due to its reliable connection and high sealing performance, neck butt welding flanges are widely used in high temperature, high pressure, and highly corrosive medium transmission pipelines, which can meet the requirements of various complex working conditions.
