FAQ's
Spades and Ring Spacers are piping components used to
positively isolate or provide an open flow path within a pipeline.
A spade is a solid plate used for complete line isolation, while a
ring spacer maintains an open flow path when installed between flanges.
A Spade is a solid plate that completely blocks
pipeline flow and is used for positive isolation. A
Ring Spacer has a central opening that allows fluid
to pass through the pipeline. They are commonly installed together
as part of a line-blind system.
Spades and Ring Spacers are commonly manufactured from:
- Carbon Steel
- Stainless Steel
- Alloy Steel
- Duplex Stainless Steel
- Nickel Alloys
The material is selected according to the pressure, temperature,
fluid compatibility, and operating conditions of the piping system.
Spades and Ring Spacers are widely used in
oil and gas, petrochemical, chemical processing, power
generation, refineries, and industrial piping systems.
They are particularly useful when pipelines need positive isolation
during maintenance, inspection, commissioning, or shutdown operations.
Spades and Ring Spacers are manufactured according to applicable
piping and flange requirements, with dimensions and materials
selected to match the connected piping system. Commonly referenced
standards include ASME B16.48 for line blanks,
along with applicable flange and material standards such as
ASME B16.5, ASME B16.47, ASTM, and ASME material
specifications, depending on the size, pressure class,
and material required.
