Marine Slip-on Loose and Elding Flange

Product Details

Slip-on Flange

Compared with common slip-on-welding flange,hubbed slip-on flange has a short neck, which increases the strength and loading capacity of the flange.Therefore,it can be used on pipeline with higher pressure.On the other hand,it is more expensive than regular plate welding flange.With a neck,the flange is easier to bump against each other during transportation.
