Spades and Carbon Steel Paddle Spacers are ideal for systems where frequent maintenance is not required. Similarly, Stainless Steel Paddle Blanks are suitable for applications involving large pipe sizes. The ASME B16.48 standard for Spades & Ring Spacers specifies pressure-temperature ratings, materials, tolerances, marking, and testing requirements. This standard applies to operational line blanks ranging from NPS 1/2 to NPS 24, designed for installation between ASME B16.5 flanges. It covers pressure classes of 150, 300, 600, 900, 1500, and 2500, and includes specific dimensions for ASME B16.48 Spacers.

Spectacle Blinds, ASME B16.48 Spades, and Ring Spacers must be made from plate or forging materials approved by ASME B31.3. These materials should have the same chemical composition as the mating flanges and piping to ensure compatibility. During maintenance, these SS Ring Spacers can temporarily replace a Spade. Once the bolts are loosened and some are removed, the Spade or Alloy Steel Ring Spacers can be inserted. It’s recommended to use new gaskets during this process to ensure a proper seal when reassembling the system.

A challenge with using Alloy Steel Spades or Spacers between flanges is that they are not easily visible once installed. To address this, handles are often specially marked and available in the market. ANSI B16.48 Class 150 Ring Spacers can also feature various designs, or customers may request custom specifications.

It is essential for Stainless Steel Ring Spacers to have the diameter and Pressure Class engraved on the handle. This marking requirement also applies to Spectacle Blinds. Proper identification helps ensure compatibility and safety during operation.

Depending on the flange size and Pressure Class, Alloy Steel Spades and Carbon Steel Paddle Spacers can be quite heavy, sometimes weighing up to hundreds of pounds. To avoid adding unnecessary weight to flange connections, it is common to use these components as separate parts rather than as part of a Spectacle Blind.

The sealing surfaces of Spectacle Blinds, ANSI B16.48 Spades, and Ring Spacers are often matched to the Face Finish of the flange. During proper assembly, the diameter of these components is slightly larger than the Raised Face of the flange to ensure that bolts are not interfered with by the Blind or Paddle Spacer.
