Carbon Steel Butt-Welding Concentric Reducer – 90×65mm for Marine Piping

This carbon steel butt-welding concentric reducer is designed for ordinary pipe systems in marine and industrial applications. It provides a smooth, gradual transition between pipes of different diameters—from 90mm to 65mm—reducing turbulence and pressure loss. The concentric design ensures a straight flow path, making it ideal for vertical or horizontal installations where alignment is critical.

Manufactured from high-quality carbon steel, this fitting offers excellent strength and durability for use in shipboard piping, ballast systems, and general fluid handling. The butt-welding ends allow for a strong, leak-proof joint when welded to matching pipe ends. With a total length of 101.6mm, it meets standard dimensional requirements for easy integration into existing systems.

Frequently Asked Questions

What is a concentric reducer used for?

A concentric reducer connects two pipes of different diameters while maintaining a straight centerline. It is used to reduce pipe size gradually, minimizing turbulence and pressure drop in the system.

Is this reducer suitable for seawater systems?

Carbon steel is not recommended for direct seawater contact without proper coating. This fitting is best used in freshwater, oil, or closed-loop systems. For seawater, consider stainless steel or bronze reducers.

How is this reducer installed?

It is installed by butt-welding the ends to matching pipe ends. Ensure proper alignment and use appropriate welding procedures for carbon steel.
