Weld Neck Flange Long Neck Pipe Flange

Weld neck flange Weld neck flange features high deformation resistance.great sealing performance,wide application range,good rigidity,resilience and reasonable thinning transition for butt welding.Distant from the welding seam,the adjoining face won't deform due to high welding temperature. Hence,the flange is suitable for pipelines with large change of pressure and temperature or tubes with high valves where the working pressure is larger than 2.5Mpa.It is also applied on pipelines for transportation of expensive. Inflammable and explosive matter. Produced by unique production process,our fla
