Duplex Steel Slip On Flange A182 F53 Class 150 ASME B16.5 Forged Steel Flanges

Slip On Flange ASME B16.5

Slip on flanges are preferred by customers because of the lower initial cost.The strength of the slip on flange is ample for it’s rating, but its life under fatigue conditions is considered to be only one third of the weld neck flange. Slip on flange is attached to the end of a piece of pipe or to one or more ends of a pipe fitting. It is not in contact with the contents of the pipe so can handle corrosive environments and save cost. 

As manufacturer and exporter of forged steel flanges, we supply ASME B16.5 Slip on flanges for overseas clients.
