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:
These components are essential in high-pressure piping systems, particularly in oil & gas, chemical processing, power generation, and shipbuilding industries.
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:
Testing & Documentation:
These quality checks guarantee that each pipe nipple meets customer specifications and global engineering expectations.
Packaging and shipping are handled with precision to maintain the product's integrity throughout transit and storage. The forged pipe nipples are securely packed following international export standards, ensuring safe delivery even in long-haul shipments. Here's what you can expect:
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:
Ideal for welding applications or systems where threaded connections aren’t needed. Ends are beveled or square cut.
Comes with NPT or BSP threads on both ends, suitable for quick connections without welding.
A reducer-style nipple that transitions between two different pipe diameters, used frequently in high-pressure systems.
Features a hexagonal center for wrench tightening; commonly used for joining threaded fittings securely.
A very short nipple with threads almost the entire length—used where space is limited.
Similar to close nipples but with extra length; typically has threads on both ends and a plain body in between.
Extended length nipples used when pipe extension is needed without using couplings.
One end has a smaller diameter, allowing connection between pipes or fittings of different sizes.
Renowned for consistent quality and adherence to international standards such as ASME B16.11 and BS 3799, forged pipe nipples from India are widely exported to over 45 countries worldwide. These components are trusted by global clients across diverse sectors, including oil & gas, petrochemicals, marine applications, power generation, and offshore drilling operations. Their reliable performance, durability under pressure, and compatibility with NPT/BSP threading systems make them ideal for high-demand piping environments.
Our primary export markets include:
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:
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. |
