What is Spade Flanges?
Spade flanges are specialised flanges used in piping systems to isolate components. They consist of two parts: a spade and a spacer. A spade is a flat piece of metal that slides between two flanges in a pipeline. When put between the flanges, it seals off the line and prevents fluid from flowing. Operators can stop the flow of fluid via the pipeline by inserting a spade between the flanges, allowing for safe operation on downstream equipment without totally depressurizing or draining the entire system.
Spade flanges are available in a variety of materials, diameters, and pressure ratings to meet specific application needs. They are typically utilised in pipelines that transport corrosive or hazardous fluids and require equipment isolation for maintenance or repair. This is especially important in industries like oil and gas, petrochemicals, and power generation, where process continuity is critical and downtime is minimised.
Piping Projects India is a leading Spade Flanges Manufacturer in India. This enables a varied range of alternatives, ensuring that customers have access to high-quality Spade Flanges that may be customized to meet their specific application needs. Spade Flanges are available in a variety of diameters and bespoke configurations, some of which are seen here.
