Cover Accessories & Ports

Flanged Access Ports

Bolt piping and equipment to the cover with a drilled flange face.

A flanged access port brings a bolt-up connection to the cover for larger piping, blowers, gas headers, and equipment. The HDPE body is fabricated as a straight riser or an elbow, welded to a base plate, and finished with a drilled flange face on a standard bolt pattern so it mates to flanged pipe and hardware.

Orientation and size are set to your layout, whether that is a vertical stub for a gas takeoff or a 90 degree elbow to run piping across the cover. A ductile iron backing ring gives a rigid, gasketed flange connection.

FAQ

Questions about this part

Flange faces are drilled to a standard bolt pattern so they mate to common flanged pipe and equipment. Tell us the size and mating flange on the quote form and the port is fabricated to match.

Yes. Flanged ports are fabricated as vertical risers, 90 degree elbows, or custom angles to fit how piping runs across your cover.
