ASME B16.5 Black Painting Weld Neck Flange Raised Face / 150LB STD Carbon Steel Welding neck Flange Serrated Finish
Welding neck flange, also known as long neck flange and necked flange, is a disc-shaped parts, mainly used to achieve the connection between the pipeline, it has been widely used in petrochemical, urban water supply and power systems. In recent years, with the planning and construction of ultra-high voltage transmission line projects of the national grid, the demand for ultra-high voltage steel pipe towers has increased dramatically.
Weldingneck flange as a new form of steel pipe tower flange connection has been proved to have certain advanced and reliable. It plays a vital role in improving the production capacity and product quality of steel pipe towers
