BOTHWELL® FORGED STEEL 90° ELBOW THREADED NPT

Forged Carbon Steel 90-Degree Elbow Threaded NPT fittings by Bothwell® are designed to change the direction of flow in a piping system by 90 degrees. These fittings are robust, durable, and ideal for high-pressure and high-temperature applications due to their forged construction and precise threading.

Specification

  1. Material:
    • Forged Carbon Steel: Typically conforms to ASTM A105, known for its strength and durability.
  2. Connection Type:
    • Threaded NPT: National Pipe Taper (NPT) threads, which are the standard for threaded pipe connections in the U.S.
  3. Angle:
    • 90 Degrees: Changes the direction of flow by 90 degrees.
  4. Pressure Rating:
    • Class 2000, 3000, 6000: Depending on application requirements, the pressure rating can vary. Common classes are 2000 (low-pressure), 3000 (medium-pressure), and 6000 (high-pressure).
  5. Size Range:
    • Typically available in sizes from 1/8 inch to 4 inches.
  6. Dimensions:
    • Dimensions vary based on size and pressure class, typically conforming to ASME B16.11 standards for forged fittings.

Classification

  1. By Pressure Rating:
    • Class 2000: Suitable for lower pressure applications.
    • Class 3000: Used in medium-pressure applications.
    • Class 6000: Designed for high-pressure applications.
  2. By Size:
    • Ranges from 1/8 inch to 4 inches, providing options for various piping needs.
  3. By Standards:
    • Conforming to ASTM A105, ASME B16.11, and ANSI/ASME B1.20.1 (NPT threading).

Description

  1. Applications:
    • Oil and Gas Industry: Widely used in pipelines for oil, gas, and petroleum products.
    • Chemical Processing: Suitable for handling various chemicals in processing plants.
    • Power Generation: Used in power plants for high-pressure steam and water lines.
    • Water Treatment: Applied in water treatment facilities for high-pressure water distribution.
    • Industrial Manufacturing: Used in various manufacturing processes requiring durable and reliable pipe fittings.
  2. Advantages:
    • High Strength: Forged carbon steel provides excellent strength and durability, suitable for high-pressure applications.
    • Corrosion Resistance: Can be treated to improve resistance to corrosion, making it suitable for harsh environments.
    • Versatility: Available in a range of sizes and pressure ratings to meet diverse application needs.
    • Leak-Proof: NPT threading ensures a secure, leak-proof connection when properly installed.
  3. Limitations:
    • Weight: Heavier compared to some other materials due to the robustness of forged carbon steel.
    • Cost: Generally more expensive than standard welded fittings due to the forging process.
    • Corrosion: Carbon steel is prone to rust if not properly coated or maintained.
  4. Maintenance and Care:
    • Regular Inspection: Inspect regularly for signs of wear, corrosion, or damage.
    • Proper Installation: Ensure proper installation using suitable thread sealants to prevent leaks.
    • Coating and Protection: Apply suitable coatings to protect against corrosion in harsh environments.
    • Replacement: Replace fittings that show significant signs of wear or damage to ensure system integrity.
