Product Overview: Stainless Steel Ring Spacers & Paddle Blinds (RF, RTJ)

Ring Spacers and Paddle Blinds are crucial safety devices designed for reliable positive shut-off or maintaining flow in critical piping systems. Dipti Metal Industries, as a leading global manufacturer, stockist, and supplier, offers a comprehensive range of premium ring spacers and paddle blinds. We ensure excellent quality and compliance for a wide variety of critical applications requiring absolute isolation, visible indication, or temporary flow worldwide. We are a leading provider of these indispensable components for enhanced operational safety, backed by our manufacturing expertise.

• Functionality:
  • A Paddle Blind (or Paddle Blank) is a solid metal disc with a handle, inserted between flanges to completely block the flow of fluid or gas. It provides a physically positive shut-off.
  • A Ring Spacer (or Spacer Ring) is an open metal ring with a handle, inserted between flanges to fill the space left when a paddle blind is removed, ensuring the correct flange spacing is maintained for continuous flow.
  • These components are typically used together or interchangeably in a single flange set, offering flexibility for maintenance, testing, or process changeovers.
• Key Benefits: Utilizing ring spacers and paddle blinds offers several advantages:
  • Absolute Positive Isolation: Provides a physical barrier, ensuring complete and verifiable shut-off of a pipeline or equipment, critical for safety protocols during maintenance or inspection.
  • Clear Visual Indication: The handle of the paddle blind or ring spacer extending outside the flange provides an unambiguous visual confirmation of whether the line is open or closed.
  • Flexibility: Unlike spectacle blinds, the blank and spacer are separate components, allowing them to be used independently or together, offering greater versatility for various operational scenarios like temporary blanking or flushing.
  • Safety Enhancement: Reduces human error and significantly improves safety in processes involving hazardous fluids or gases by providing a robust and clear isolation method.
  • Easy Handling: The handles facilitate easier insertion and removal of the components between flanges.
• Standards Compliance: Our ring spacers and paddle blinds are manufactured and supplied in strict accordance with:
  • ASME B16.48: The specific standard covering dimensions, tolerances, marking, and material requirements for line blanks (which include paddle blinds and ring spacers).
  • They are designed to mate with flanges conforming to ASME B16.5 or ASME B16.47 for bolting and facing dimensions.
  • Adherence to these standards ensures dimensional compatibility, structural integrity, and material quality, making us a top global manufacturer and supplier.
• Facing Types Available: Ring Spacers and Paddle Blinds are commonly supplied with two main facing types to ensure optimal sealing:
  • Raised Face (RF): The most popular choice for general service, concentrating the gasket load for an effective seal. We precision manufacture these faces for optimal sealing.
  • Ring Type Joint (RTJ): Features a machined groove into which a metallic ring gasket (oval or octagonal cross-section) is fitted. Ideal for high-pressure, high-temperature, and critical sealing requirements. We precision machine these grooves.
  • We provide the best facing options for your diverse sealing needs globally.

We manufacture and stock an extensive range to suit varied industrial demands:

• Class 150# (PN10 / PN16): Suitable for low-to-medium pressure applications, general service, and utilities.
• Class 300# (PN25 / PN40): Common for medium-pressure applications in process piping.
• Class 400# (PN64): Often specified for intermediate pressure applications requiring reliable isolation.
• Class 600# (PN100): For higher-pressure services in oil & gas, petrochemical.
• Class 900# (PN150): High-pressure applications, often in power generation and steam lines.
• Class 1500# (PN250): Very high-pressure services, critical for severe isolation applications.
• Class 2500# (PN420): Extremely high-pressure applications, demanding maximum integrity and safety isolation.

Dipti Metal Industries offers an extensive selection of ring spacers and paddle blinds, manufactured by us or sourced, for all these pressure ratings, ensuring we meet the substantial demands of critical projects globally. Our range is dependable and excellent quality.

Facing Types for Ring Spacers & Paddle Blinds, Precision Manufactured

The facing of ring spacers and paddle blinds is crucial for establishing a secure, leak-proof seal between the components and the mating pipe flanges. We manufacture and supply these components with the most common and effective facing types, ensuring precision engineering, vital for their superior performance:

• Raised Face (RF):
  • Description: The gasket surface is raised above the bolting circle face of the mating flanges. Both ring spacers and paddle blinds are manufactured with this profile. We precision machine these faces for optimal sealing.
  • Usage: The most common facing type for general service, concentrating the gasket load for an effective seal with various non-metallic and metallic gaskets.
  • Applications: Widely used across almost all industries for general and medium-pressure isolation and flow.
• Ring Type Joint (RTJ):
  • Description: Features a precision-machined groove on both the ring spacer and paddle blind to accommodate a metallic ring gasket (oval or octagonal cross-section) within the mating RTJ flanges. We precision machine these grooves.
  • Usage: Provides a metal-to-metal seal, creating a very strong, leak-proof connection. Ideal for high-pressure, high-temperature, and severe corrosive applications where positive sealing and absolute isolation are paramount.
  • Applications: Heavily used in oil & gas, petrochemical, and power generation industries for critical safety and isolation. Considered a premium choice for extreme conditions.

Our comprehensive stock includes ring spacers and paddle blinds, both manufactured by us and sourced, with these facing types, ensuring Dipti Metal Industries is a primary source for optimal sealing and positive isolation solutions worldwide.

    • Ultrasonic Testing (UT): To detect internal discontinuities within the material of both the ring and blind sections, ensuring integrity.
    • Magnetic Particle Testing (MPT) / Liquid Penetrant Testing (LPT): To detect surface and near-surface discontinuities, critical for ensuring the integrity of sealing surfaces.
    • Hydrostatic Testing: To verify the pressure-retaining capability of the paddle blind (when in the closed position), crucial for positive isolation, manufactured by us.
• Mechanical Testing:
  • Includes tensile tests, hardness tests, and impact tests (e.g., Charpy V-notch for low-temperature service as per ASTM A350 LF2 equivalent materials), performed on our manufactured ring spacer and paddle blind material to ensure it meets specified mechanical property requirements, particularly for the paddle blind's pressure containment.
• Corrosion Testing:
  • For corrosion-resistant alloy ring spacers and paddle blinds (e.g., stainless steels, nickel alloys) that we manufacture, specific tests like intergranular corrosion tests (e.g., ASTM A262) or pitting/crevice corrosion tests (e.g., ASTM G48) are performed to confirm resistance to aggressive environments, including those requiring NACE compliance.
• Certification & Documentation:
  • All our manufactured ring spacers and paddle blinds are supplied with full Mill Test Certificates (MTCs) conforming to EN 10204 Type 3.1 and 3.2. This is crucial for international projects and reflects our commitment as a manufacturer.
    • Type 3.1: Certified by our manufacturer's authorized inspection representative, confirming compliance with order requirements.
    • Type 3.2: Independently verified by an authorized third-party inspection (TPI) agency (e.g., TÜV, Lloyd's Register, DNV, ABS), providing additional assurance for critical applications for our manufactured products.
  • Our entire supply chain and quality management systems are ISO 9001 certified, guaranteeing consistent quality control and documented processes throughout our manufacturing operations.

This rigorous testing and comprehensive certification process, integral to our manufacturing, reinforces Dipti Metal Industries as a highly reliable global manufacturer and supplier of ring spacers and paddle blinds, instilling full confidence for large-scale critical projects worldwide.
