What is a Forged Pipe Nipple?

A forged pipe nipple is a short length of pipe with male threads on one or both ends, designed for connecting two other fittings or pipes. Manufactured from forged round bar or seamless pipe, these nipples are commonly used to extend pipe runs or adapt different sizes and ends.

Forged nipples are stronger than standard welded nipples due to the forging process, which increases material density and mechanical strength. Depending on the application, they are available in various end types such as:

  • Threaded Ends (NPT/BSP)
  • Plain Both Ends (PBE)
  • Male x Male / Male x Female combinations

These components are essential in high-pressure piping systems, particularly in oil & gas, chemical processing, power generation, and shipbuilding industries.

What Quality Standards and Certifications Are Followed for Forged Pipe Nipples?

To ensure reliability, durability, and compliance with international standards, forged pipe nipples are manufactured under strict quality control procedures. The production process adheres to several industry-recognized certifications and testing protocols, including:

Manufacturing Standards:

  • ASME B16.11
  • BS 3799
  • MSS-SP-79
  • DIN 2982 (on request)

Testing & Documentation:

  • 100% Dimensional Inspection
  • Hydrostatic / Pneumatic Testing
  • PMI (Positive Material Identification)
  • Hardness and Tensile Testing
  • EN 10204 3.1 / 3.2 Certified Test Reports

These quality checks guarantee that each pipe nipple meets customer specifications and global engineering expectations.

    • Worldwide delivery through trusted logistics partners
What Are the Different Types of Forged Pipe Nipples Available?

Nipples come in a wide range of types to suit various piping requirements across industries. Each type is designed based on connection style, end finish, and dimensional needs. Below is a comprehensive list of nipple types offered:

  1. Plain Nipple (PBE – Plain Both Ends):

    Ideal for welding applications or systems where threaded connections aren’t needed. Ends are beveled or square cut.

  2. Threaded Nipple:

    Comes with NPT or BSP threads on both ends, suitable for quick connections without welding.

  3. Swage Nipple:

    A reducer-style nipple that transitions between two different pipe diameters, used frequently in high-pressure systems.

  4. Hex Nipple:

    Features a hexagonal center for wrench tightening; commonly used for joining threaded fittings securely.

  5. Close Nipple:

    A very short nipple with threads almost the entire length—used where space is limited.

  6. Barrel Nipple:

    Similar to close nipples but with extra length; typically has threads on both ends and a plain body in between.

  7. Long/Extra-Long Nipple:

    Extended length nipples used when pipe extension is needed without using couplings.

  8. Reducing Nipple:

    One end has a smaller diameter, allowing connection between pipes or fittings of different sizes.

Which Countries Does We Export Forged Nipples To?

  • North America: USA, Canada, Mexico
  • South America: Brazil, Argentina, Colombia, Chile
  • Australia & New Zealand
What is a Reducer Nipple and When Would You Use It?

A reducer nipple, also known as a reducing nipple, is a type of pipe fitting designed to connect two pipes of different diameters. It features two male-threaded ends—one with a larger diameter and the other with a smaller diameter—allowing for a smooth transition between varying pipe sizes in a system.

When to use a reducer nipple:

  • Flow Transition: When fluid or gas needs to move between two pipelines of different sizes without disturbing the system’s flow characteristics.
  • Compact Installations: In applications where space is limited and reducers or adapters may not fit.
  • Pressure Regulation: To manage system pressure by stepping down or up the flow line.
  • Temporary or Custom Connections: When you need a quick or non-standard transition between equipment or lines.
What is the Difference Between a Straight Nipple and a Hex Nipple?

Though both straight and hex nipples serve the purpose of connecting two female-threaded components, they differ in structure and utility:

Feature Straight Nipple Hex Nipple
Design Uniform cylindrical shape with threads on both ends. Includes a hexagonal center section for wrench tightening.
Tool Access Typically hand-tightened; less suitable for high-torque fittings. Allows easy installation/removal using a spanner or wrench.
Application Area Ideal for simple inline connections in low-stress environments. Preferred in high-pressure or vibration-prone systems.
Handling Can be difficult to remove if over-tightened. Hex portion simplifies installation and disassembly.
