The Spade or Spacer is fitted in the line between two flanges and is bolted in place. The Spacer is used when the line is required open and the Paddle Blind or Spade is installed when the line is required to be blocked or closed.
Spades and ring spacers are essential components in piping systems, often used in conjunction with flanges to control and manage the flow of fluids or gases in pipelines. These devices play a crucial role in isolating sections of a pipeline for maintenance, repair, or to divert the flow as needed. Let's delve into an introduction to spades and ring spacers.

Spades: Spades are metal plates, usually in the shape of a paddle or spade, that are placed between two flanges. They are used to isolate a section of the pipeline temporarily.
Ring Spacers: Ring spacers are circular metal pieces with an opening in the center. They serve a similar purpose to spades but provide a complete separation between flanges.
Isolation and Flow Control: Spades and ring spacers are primarily employed for isolating a particular section of a pipeline for maintenance or repair activities. By inserting a spade or a ring spacer between flanges, the flow of fluids or gases can be redirected, allowing work to be carried out on the isolated section without affecting the rest of the pipeline.
Materials: These components are typically made from materials that match the specifications of the adjoining pipeline. Common materials include carbon steel, stainless steel, and alloy steel, ensuring compatibility with the fluids or gases flowing through the pipeline.
Types: Blind Spades: These are solid plates used for complete isolation. Paddle Spades: Shaped like a paddle, these allow for partial flow diversion. Ring Spacers: Circular in shape, they provide a complete separation between flanges.
Installation: Installation involves placing the spade or ring spacer between two flanges and securing them with bolts. Proper alignment and tightening are crucial to maintain the integrity of the pipeline.
Standards and Specifications: The design and dimensions of spades and ring spacers are often governed by industry standards such as ASME B16.48. Compliance with these standards ensures uniformity and compatibility in different piping systems.
Safety Considerations: Proper installation and adherence to safety guidelines are essential to prevent leaks or accidents during maintenance activities. Thorough inspection and testing are recommended before resuming regular operations.
Spades and ring spacers play a critical role in the efficient and safe operation of piping systems by providing a means to isolate specific sections for maintenance while minimizing disruption to overall operations. Their design, material selection, and proper installation are key factors in ensuring the reliability and safety of these components within industrial processes.

What is a Spades and Ring Spacers?
Spades and Ring Spacers are similar to Spectacle Blinds, with the exception that they are not attached.
Spades and spacers are used in systems where maintenance is rarely required, or in applications involving enormous pipe diameters. Spades can weigh hundreds of pounds, depending on their flange size and Pressure Class. To avoid adding additional weight to flange connections, it is normally preferred to use two distinct components rather than a Spectacle Blind.
As with the previously described Spectacle Blind, pipe system maintenance may necessitate temporarily replacing a Ring Spacer with a Spade. The Spade or Spacer can be installed after loosening all bolts and temporarily removing half of them. After replacing the gaskets (new gaskets are recommended), reassemble and tighten the bolts.
A minor issue is that we cannot see a spade or a spacer mounted between the flanges. As a result, the handles are frequently specially marked, or both have a different design; a customer may specify their own specifications.
What should never be lacking is engraving the diameter and pressure class of a spade or spacer on the handle; this also applies to the Spectacle Blind.
