RUNNING NIPPLE(TN)

RUNNING NIPPLE (TN) – High-Strength Threaded Extension for Precise Pipe Spacing

The RUNNING NIPPLE (TN) is a specialized, high-precision pipe fitting designed to extend or space two female-threaded components in high-pressure fluid, gas, or steam systems. Featuring external threads on both ends and a smooth, cylindrical body, this fitting ensures a secure, leak-proof connection while maintaining structural integrity under extreme operating conditions. Manufactured using the advanced lost wax casting process, it delivers exceptional dimensional accuracy, superior surface finish, and consistent mechanical properties—making it ideal for critical applications in oil & gas, chemical processing, power generation, and marine industries.

Key Features & Benefits

• Dual External Thread Design: Allows for seamless connection between two female-threaded fittings or pipes, ensuring a tight, vibration-resistant seal that prevents leaks and system failure.

• Precision-Length Body: The cylindrical shaft is engineered to exact specifications, providing consistent spacing and alignment in complex piping assemblies.

• High-Strength Material Options: Available in stainless steel, carbon steel, alloy steel, and tool steel, offering excellent resistance to corrosion, high temperatures, and mechanical stress.

• Lost Wax Casting Process: Ensures superior surface finish, tight tolerances, and internal soundness, reducing the risk of cracks or porosity under pressure.

• Global Compliance: Manufactured to ASTM, JIS, DIN, and BS NF standards, ensuring compatibility with international piping systems and regulatory requirements.

Technical Specifications

Applications

• Oil & Gas: Used in wellhead assemblies, manifolds, and pipeline extensions where precise spacing and high pressure resistance are critical.

• Chemical Processing: Ideal for connecting reactors, valves, and instrumentation in corrosive environments.

• Power Generation: Employed in steam lines, boiler systems, and turbine connections requiring high-temperature durability.

• Marine & Shipbuilding: Used in hydraulic systems, fuel lines, and ballast systems where space is limited and reliability is paramount.

This fitting is a vital component in any system requiring a durable, threaded extension with precise dimensional control. Its robust design and high-quality manufacturing process ensure long-term performance and safety in demanding industrial environments.
