Description

CuNi 70/30 Copper Nickel 90° LR Elbow, High Strength ASME B16.9 Butt Weld Fitting

1.Product Description

The Copper Nickel Elbow is a prefabricated, factory‑tested pipe fitting ready for field installation. It is manufactured from corrosion‑resistant CuNi alloys (C70600/C71500) and delivered in the solution‑annealed condition, with ends prepared to specification for rapid fit‑up. Each elbow is supplied with end protectors and clear marking for easy identification on the job site. The product is compatible with standard pipe sizes and schedules, enabling direct integration into new or existing seawater piping systems.

2.Product Applications

This elbow is used in the following typical field installation scenarios:

  • Shipboard piping erection in newbuild shipyards and dry‑dock repair yards

  • Offshore platform topside piping hook‑up and tie‑in works

  • Seawater intake and outfall pipeline construction for coastal power plants

  • Retrofit and expansion projects in existing desalination and chemical plants

  • Submarine pipeline riser connections and topside jumper installations

  • General replacement of corroded carbon steel or galvanized elbows in marine environments

3 · Product Advantages

  • Lightweight compared to steel – Approximately 85% weight of equivalent carbon steel elbow; easier manual handling and rigging.

  • Low magnetic permeability – Allows welding near sensitive equipment without magnetic field interference.

  • Oxide‑free surface – Factory pickling removes scale, minimizing contamination risk during welding.

  • Forgiving fit‑up – Dimensional tolerances allow ±1.5 mm misalignment correction during alignment.

  • Reduced post‑weld treatment – No post‑weld heat treatment (PWHT) required for thicknesses up to 30 mm.

  • Reusable – Can be cut, re‑beveled, and re‑welded in the field for modification purposes.
