Swage Nipples – Eccentric (TBE, BBE, PBE)

Eccentric Swage Nipples are designed to connect pipes of different diameters while maintaining a non-centered (offset) alignment. This design is particularly useful in piping systems where drainage, venting, or maintaining a specific flow direction is critical. Available in Threaded (TBE), Bevel (BBE), and Plain (PBE) end types, these fittings provide flexibility for both welded and threaded installations. Manufactured with precision, they ensure high strength, durability, and reliable performance in demanding industrial environments such as oil & gas, petrochemical, and process industries.

FAQ

Swage Nipples – Common Questions

What are Eccentric Swage Nipples? +

Eccentric Swage Nipples are pipe fittings used to connect pipes of different diameters while maintaining an offset (non-centered) alignment. This helps in proper drainage and prevents fluid accumulation in piping systems.

What end connections are available? +

They are available in Threaded Both Ends (TBE), Bevel Both Ends (BBE), and Plain Both Ends (PBE), allowing flexibility for both welded and threaded piping systems.

Why use eccentric instead of concentric swage nipples? +

Eccentric swage nipples are preferred where drainage or flow direction is important, especially in horizontal pipelines, as they prevent air pockets and liquid accumulation.

What materials are used for manufacturing? +

They are manufactured using high-quality Carbon Steel, Stainless Steel, and Alloy Steel to ensure strength, durability, and corrosion resistance in demanding environments.

What are the pressure ratings? +

Eccentric swage nipples are available in both threaded pressure classes (3000, 6000, 9000) and pipe schedule ratings (SCH 40, 80, 160, XXH) depending on the end connection type.
