Brief Description

Welding Neck Flanges – Smooth hub transition from flange to weldend. Most common type of high-pressure flanges.

Slip-On Flanges – This flange fits over the pipe and is then welded in position.

Socket Weld Flanges – Pipe fits in to the recess to allow smooth flow through the flange.

Lap Joint Flanges – Mainly used with a matching stub end. Bolt holes can be aligned with pipe after welding.

Threaded Flanges – can be attached to the pipe without welding. Saves time and cost.

Swivel Ring Flanges – Mostly used for ease of assembly at subsea. High strength and resistance to external loads.

Blind Flanges – Normally a flat disk with raised or RTJ face to match mating flange.

Orifice Flanges – Mainly used for flow rate metering of pipelines.

Anchor/Hanger Flanges – supports pipelines and risers.
