Product Overview: Stainless Steel Orifice Flanges (RF, RTJ)

Orifice Flanges are specialized piping components central to accurate flow measurement in industrial processes. Dipti Metal Industries, as a leading global manufacturer, stockist, and supplier, offers a comprehensive range of premium orifice flanges. We ensure excellent quality and compliance for a wide variety of critical applications requiring precise fluid and gas metering worldwide. We are a leading provider of these essential components for process control and efficiency, backed by our manufacturing expertise.

• Functionality: An Orifice Flange assembly consists of a pair of flanges with unique features to accommodate an orifice plate and provide pressure taps. An orifice plate (a thin metal disk with a precisely bored hole) is clamped between the two flanges, creating a differential pressure as fluid flows through it. The integral pressure taps on the flanges allow connection to a differential pressure transmitter, which measures this pressure drop, enabling the accurate calculation of flow rate. They often include jack screws to facilitate easy removal and inspection of the orifice plate.
• Key Benefits: Utilizing orifice flanges offers several advantages:
  • Accurate Flow Measurement: Provides a highly reliable and standardized method for determining flow rates in pipelines.
  • Process Control: Essential for precise control of fluid and gas processes in industries where accurate dosing or monitoring is critical.
  • Easy Maintenance: Equipped with jack screws, allowing for quick and simple removal or replacement of the orifice plate without disassembling the entire pipeline.
  • Cost-Effective: Compared to some other flow metering technologies, orifice plates and flanges offer a robust and economical solution.
  • Versatility: Can be used for a wide range of fluid types (liquids, gases, steam) and operating conditions.
• Standards Compliance: Our orifice flanges are manufactured and supplied in strict accordance with:
  • ASME B16.36: The specific standard covering dimensions, tolerances, marking, and material requirements for orifice flanges.
  • ASME B16.5: The base standard for the flange portion itself, ensuring compatibility in terms of bolting, facing, and pressure ratings.
  • Adherence to these standards ensures dimensional compatibility with orifice plates, accurate pressure tap locations, pressure integrity, and material quality, making us a top global manufacturer and supplier.
• Facing Types Available: Orifice flanges are commonly supplied with two main facing types to ensure optimal sealing with the orifice plate and gaskets:
  • 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.

The pressure class of an orifice flange indicates its maximum allowable working pressure at specified temperatures, aligning with the requirements of ASME B16.36 and the underlying ASME B16.5 rating of the flange. 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, ensuring precise metering.
• 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 measurement applications.
• Class 2500# (PN420): Extremely high-pressure applications, demanding maximum integrity and measurement precision.

Dipti Metal Industries offers an extensive selection of orifice flanges, 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.

Flange Facing Types for Orifice Flanges, Precision Manufactured

The flange facing is crucial for establishing a secure, leak-proof seal with the orifice plate and associated gaskets. We manufacture and supply orifice flanges 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. This is the most common facing type for orifice flanges. We precision machine these faces for optimal sealing.
  • 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 flow measurement.
• Ring Type Joint (RTJ):
  • Description: Features a machined groove into which a metallic ring gasket (oval or octagonal cross-section) is fitted. 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 measurement integrity are paramount.
  • Applications: Heavily used in oil & gas, petrochemical, and power generation industries for critical flow metering. Considered a premium choice for extreme conditions.

Our comprehensive stock includes orifice flanges, both manufactured by us and sourced, with these facing types, ensuring Dipti Metal Industries is a primary source for optimal sealing and accurate flow measurement solutions worldwide. We are a top global manufacturer and exporter of diverse orifice flange solutions.
