Spacer & Spade Flanges Suppliers

Spacer and Spade Flanges are preferred over Spectacle Blinds in large-diameter or heavy-duty pipeline systems where weight, space, and handling flexibility are crucial. Unlike Spectacle Blinds (which are a single combined unit with both open and blind discs), Spade and Spacer Flanges are individual components used when there’s not enough room or lifting capacity to install a full spectacle blind.

They are ideal for ASME B16.5 and B16.47 flange systems, especially in Class 600 to Class 1500 pressure ratings, and are commonly seen in hydrocarbon processing, high-pressure steam lines, and offshore platforms. Because they are installed separately, they allow for easier handling, faster maintenance, and reduced downtime, making them highly efficient in critical shutdown and start-up operations.

Yes, Spacer and Spade Flanges can be integrated into automated or remotely controlled piping systems, but typically require manual intervention for swapping the components. Unlike valve-based automation, Spade (blind) and Spacer (open) elements must be manually removed and installed during maintenance or system isolation.

However, in some critical operations, they're installed in easily accessible sections of the piping line, and flange joints are designed for quick access. Some modern facilities use hydraulic or mechanical lifting tools to streamline the changeover process.

These flanges are often chosen in automated systems when absolute line isolation is necessary and a valve alone may not provide full sealing under certain conditions.

Yes, Spacer & Spade Flanges are specifically designed to handle high-pressure and high-temperature pipeline conditions. They are manufactured in accordance with international pressure class ratings such as ASME Class 150, 300, 600, 900, and 1500, and made from heat-resistant alloys like Stainless Steel 316H, Alloy Steel F11/F22, Inconel 625, and Super Duplex UNS S32750.

These flanges are commonly used in refineries, petrochemical plants, offshore platforms, and power plants, where precise line isolation is critical during maintenance or emergency shutdowns. Additionally, their flat-faced or raised-faced designs, and precise machining, ensure leak-proof performance under extreme operating conditions.

Spacer & Spade Flanges offer a mechanically simple yet highly reliable method for complete line isolation, especially in systems that require frequent shutdowns or positive sealing. Unlike valves that can fail over time due to internal leakage or seat erosion, a spade or spacer provides 100% mechanical blockage, ensuring zero flow when closed.

They are widely used in:

• Petrochemical units during maintenance shutdowns
• Pipeline isolation in high-temperature or corrosive media
• Offshore and subsea lines where space and safety are critical

Additionally, their visual indication (whether a spacer or spade is installed) improves safety and system transparency, which makes them indispensable in critical applications where a valve alone may not guarantee full isolation.
