Product Overview: Stainless Steel Spade & Paddle Blanks (RF, RTJ)

Spade Blanks and Paddle Blanks are essential components for achieving positive isolation in pipelines, crucial for safety and operational efficiency. Dipti Metal Industries, as a largest global manufacturer, stockist, and supplier, offers a comprehensive range of premium spade and paddle blanks, ensuring the best quality and compliance for a large variety of pipeline isolation applications worldwide. We are a leading provider of these essential components for operational integrity.

• Spade Blank (Paddle Blank):
  • Function: A solid metal plate with an attached handle (paddle). It is inserted between two flanges, with a gasket on each side, to completely block the flow of fluid or gas. Our manufacturing ensures precise dimensions for a tight fit.
  • Usage: Primarily used for achieving "positive isolation" of pipeline sections during critical maintenance, repair, alteration, or hydrotesting. This is vital for worker safety and preventing accidental release of hazardous materials.
  • Features: The handle extends outside the flange bolts, making its presence and orientation easily visible, providing a crucial visual safety indication.
• Spectacle Blind (Figure-8 Blind):
  • Function: A single piece of metal cut into a figure-8 shape, with one end a solid blank and the other an open ring. It is permanently installed in the pipeline and can be rotated to either block or allow flow.
  • Usage: Used for quick and easy isolation or flow passage without removing the entire device from the pipeline, ideal for frequently maintained sections.
  • Benefits: Offers convenience and speed for operational changes, with a clear visual indication of flow status. We also manufacture these versatile blanks.
• Standards Compliance: Our spade, paddle, and spectacle blanks are manufactured and supplied in strict accordance with:
  • ASME B16.48 (Line Blanks, Spades, and Spacers): The primary standard governing dimensions, pressure-temperature ratings, and material requirements for these components.
  • ASME B16.5 & B16.47: Dimensions for blanks often align with these flange standards for seamless mating.
  • EN 1092-1, DIN, JIS: Relevant European and Asian standards for material and design compatibility.
  • Adherence to these standards ensures dimensional interchangeability, pressure integrity, and material quality, making us a top global manufacturer and supplier.
• Facing Types Available: These blanks are commonly supplied with two main facing types to ensure optimal sealing when inserted between flanges, which we precision manufacture:
  • Raised Face (RF): The most popular choice for general service, concentrating the gasket load for an effective seal.
  • Ring Type Joint (RTJ): Features a machined groove for a metallic ring gasket, ideal for high-pressure, high-temperature, and severe corrosive applications where positive metal-to-metal sealing is paramount.
  • We provide the best facing options for your diverse sealing needs globally.

Dipti Metal Industries offers the biggest and best selection of spade, paddle, and spectacle blanks, making us a top choice for dependable and safe pipeline isolation solutions across all critical industries worldwide. We are a reliable and comprehensive global manufacturer and supplier.

  • Class 600# (approx. EN PN100 equivalent): For higher-pressure services in oil & gas, petrochemical.
  • Class 900# (approx. EN PN150 equivalent): High-pressure applications, often in power generation and steam lines.
  • Class 1500# (approx. EN PN250 equivalent): Very high-pressure services, critical for severe applications.
  • Class 2500# (approx. EN PN420 equivalent): Extremely high-pressure applications, demanding maximum integrity.
  • Our manufacturing capabilities ensure we can produce blanks for the biggest pressure demands across this full range.

Dipti Metal Industries offers the biggest selection of spade and paddle blanks, either manufactured by us or sourced, for all these pressure ratings, ensuring we meet the large demands of critical projects globally. Our range is dependable and top quality.

Facing Types for Spade & Paddle Blanks, Precision Manufactured

The facing of these components is crucial for establishing a secure, leak-proof seal when inserted between flanges. We manufacture and supply spade and paddle blanks with the most common and effective facing types, ensuring precision engineering:

• Raised Face (RF):
  • Description: The gasket surface is raised above the bolting circle face. This is the most common facing type for spade and paddle blanks, precision-manufactured by us to match mating RF flanges.
  • Usage: Designed to concentrate the compressive load on a smaller gasket area, increasing the joint's ability to contain pressure. Used with various non-metallic and metallic gaskets.
  • Applications: Widely used across almost all industries for general and medium-pressure service.
• Ring Type Joint (RTJ):
  • Description: Features a precisely machined groove into which a metallic ring gasket (oval or octagonal cross-section) is fitted. We precision machine these grooves in our manufacturing process to match mating RTJ flanges.
  • 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 is paramount.
  • Applications: Heavily used in oil & gas, petrochemical, and power generation industries. Considered a premium choice for extreme conditions.

Our comprehensive stock includes spade and paddle blanks, both manufactured by us and sourced, with these facing types, ensuring Dipti Metal Industries is the best source for optimal sealing solutions in piping systems worldwide. We are a top global manufacturer and exporter of diverse spade and paddle blank solutions.
