Carbon Steel CS Paddle Blank and Spacer/Sapde and Spacer

Carbon Steel Paddle Blanks and Spacer/Spade and Spacer made from ASTM A516 Grade 60/70 are commonly used in pressure vessel and piping systems. They are designed to isolate sections of pipelines for maintenance or operational changes. Below are the detailed specifications, including material grades and equivalents for these components.1. Description• Paddle Blank: A solid plate used to block the flow through a pipeline.• Spacer/Spade and Spacer: A combination where:o Spade (or Spade Plate): Contains a hole to facilitate or bypass flow.o Spacer (or Spacer Ring): Fits between flanges to maintain alignment.2. Material GradesCarbon Steel ASTM A516 Grade 60/70 is used for its good weldability and moderate strength. It is widely used for pressure vessel plates.1. ASTM A516 Grade 60o : Carbon steel used for moderate and lower temperature applications.2. ASTM A516 Grade 704. Pressure RatingsPressure ratings depend on the class of the component:• Class 150: Low-pressure applications• Class 300: Medium-pressure applications• Class 600: High-pressure applications• Class 900: Very high-pressure applications• Class 1500: Extremely high-pressure applications• Class 2500: Ultra-high-pressure applications5. Standards• ASME B16.5/B16.48: Provides dimensions, materials, and pressure-temperature ratings for flanges and fittings, including paddle blanks, spades, and spacers.• MSS SP-44: Specification for spectacle blinds, spades, and spacers with detailed dimensions and pressure ratings.6. Testing and Quality Control• Visual Inspection: To identify visible defects.• Dimensional Inspection: To ensure compliance with specifications.• Non-Destructive Testing (NDT): Techniques such as ultrasonic testing or radiographic testing to verify material integrity.SummaryCarbon Steel ASTM A516 Grade 60/70 Paddle Blanks and Spade/Spacer Components are used for pipeline isolation and flow control. They are available in different pressure classes and dimensions based on standards like ASME B16.5 and MSS SP-44. The material grades ASTM A516 Grade 60 and Grade 70 provide good weldability and moderate to high strength, suitable for various temperature and pressure conditions. Proper marking and rigorous testing ensure these components' safety and effectiveness in pipeline systems.SPECFICATIONS:• Manufacturing Range: DN 15 (1/2”) to DN 1500 (60”)• Rating/Class: 150/300/600/900/1500/2500 and SCH 5/5S/10/10S/20/40/STD/60/80/XS/100/120/140/160/XXS etc.• Dimension Standard: ANSI/ASME B16.48/B16.5, etc.Material Type: CARBON/ALLOY STEEL: ASTM/ASME A105/105N, ASTM / ASME A182, ASTM / ASME A335 GR F1, F5, F9, F11, F12, F22, F23, F91, ASTM A516 GR 60/70, ASTM A516 GR 60, ASTM A516 GR 70LTCS: ASTM/ASME A350 LF2, ASME/ASTM A694 F42, F46, F52, F60, F65, F70
