Concentric Swage Nipples designed to connect pipes of different diameters in a straight-line configuration. These fittings are commonly used in piping systems where smooth, gradual reduction or transition between two different pipe sizes is required—while maintaining flow direction and minimizing turbulence.
Concentric swages are manufactured in both seamless and welded types and are available in a wide range of sizes, thicknesses, and materials. They are machined from forged barstock or seamless pipe, and comply with international standards such as ASME B16.11, MSS-SP-95, and BS3799, making them suitable for high-pressure and high-temperature applications.
We offer concentric swage nipples in materials such as Carbon Steel (ASTM A105, A234 WPB), Stainless Steel (ASTM A182 F304/F316), Duplex, Super Duplex, and Nickel Alloys, depending on the service medium and industry requirements. End connections include plain end (PE), beveled end (BE), threaded (NPT/BSP), or socket weld (SW).
These fittings are widely used in oil & gas plants, refineries, power generation, petrochemical facilities, shipbuilding, and water treatment projects, where pressure integrity and dimensional precision are critical. click here for pipes
Middle East Piping ensures all swage nipples are manufactured under strict quality control. Each fitting is supplied with EN 10204 3.1 material test certificates, and can undergo further testing such as hydrotesting, PMI, NDT, and third-party inspection (TPI) as per project requirements. click here for valves
