Spade Flange

SA 515 Grade 70 is a carbon steel plate grade that is primarily used for intermediate- and higher-temperature service in welded boilers and pressure vessels. Spade blind flanges are specialty flanges that are used to blank off or isolate sections of a piping system. The spade portion is typically used to blank off the line, while the ring spacer is used to maintain the structural integrity of the flange assembly. Here are key points about SA 515 Grade 70 spade blind flanges: Material - SA 515 Grade 70: SA 515 Grade 70 is a carbon steel plate grade with good tensile strength and excellent corrosion resistance, making it suitable for use in moderate- to lower-temperature applications. Design and Purpose: The spade portion of the spade blind flange is the blanking or blocking plate that is inserted between the flanges to stop the flow of fluid or gas. The ring spacer portion helps maintain the integrity and alignment of the flange assembly. Applications: Spade blind flanges with SA 515 Grade 70 material are commonly used in industrial applications, particularly in high-temperature and pressure piping systems, boiler assemblies, and pressure vessels. Usage Guidelines: Spade blind flanges are used during maintenance or repairs when a section of a pipeline needs to be isolated for maintenance, cleaning, or repair work. The spade (blanking plate) is installed when a particular section of the pipeline needs to be blocked off, temporarily stopping the flow. Standards and Specifications: SA 515 Grade 70 spade blind flanges would generally adhere to ASME B16.48 standard, which covers line blanks, spacer flanges, and blanks. Material Selection Considerations: The choice of SA 515 Grade 70 material for the spade blind flange is based on factors such as operating temperature, pressure, and compatibility with the medium being transported. When using SA 515 Grade 70 spade blind flanges, it's crucial to follow industry standards and ensure the flanges are appropriate for the intended application and operating conditions. Proper installation and usage are essential for the safe and efficient functioning of the piping system.
