 Orifice Flange designed for flow measurement and metering systems in oil, gas, and process industries.

Size Range: ½" NB to 24" NB

Dimension Standards: ASME B16.36, ASME B16.5

Pressure Class: Class 150 to 2500

 Paddle Spacer or Ring Spacer used as a temporary line opening or isolation device in pipeline systems for inspection, maintenance, or cleaning. Paddle Spacers (Ring Spacers) are installed between flanges to maintain the gap when the flow is open, acting as the “spacer” part of a spectacle blind set. Commonly used in oil & gas refineries, offshore platforms, petrochemical plants, and power stations.

Size Range: ½" NB to 36" NB

Dimension Standards: ASME B16.48, ASME B16.5, API 605, EN 1092-1

Pressure Class: Class 150, 300, 600, 900, 1500, 2500

 Line Blinds or Paddle Blinds or Paddle Blanks (Spades) are used to block the flow in a pipeline for maintenance or testing purposes. They serve as the “blank” portion of a spectacle blind and are inserted between two flanges to completely shut off the flow. Ideal for refinery, chemical, gas processing, and power generation pipelines.

Size Range: ½" NB to 36" NB

Dimension Standards: ASME B16.48, ASME B16.5, API 605, DIN, EN 1092-1

Pressure Class: Class 150 to 2500
