What is a Spade Flange?

A Spade Flange (Paddle Blank) is a round plate with a handle designed to be inserted between two pipe flanges, completely blocking the pipeline when bolted into place. It is widely used during shutdowns, pipeline cleaning, and maintenance operations where safe isolation of the flow is required.

• Reliable Alternative to isolation valves.

• Safer Maintenance in oil, gas, and chemical plants.

• Easy Operation – Open position for normal flow, closed position for isolation.

• Industries Served: Oil & Gas, Petrochemical, Refinery, Power Generation, Chemical, Marine, Offshore, Food & Pharma.
