Product Description

 Long Weld Neck Flanges

Long Weld Neck Flanges are distinguished from other flanges by their long tapered hub and gentle transition of thickness in the region of the butt weld, joining them to the pipe. This type of long welding neck flange is preferred for application in the piping system which involves high pressure and elevated temperature. We specialize in manufacturing stainless steel long weld neck flanges in both alloy and non alloy materials based upon the application requirement of the clients.
