Choosing the Right Pipe Material for Marine Applications: Why Copper-Nickel Stands Out

In the marine industry, selecting the right piping material is crucial for ensuring durability, corrosion resistance, and long-term performance. Among the various options available, copper-nickel piping has emerged as a top choice for shipbuilding, offshore platforms, and other marine applications.

Why Copper-Nickel?

Copper-nickel alloys, commonly available in 90/10 and 70/30 compositions, offer excellent resistance to seawater corrosion, biofouling, and extreme temperatures. This makes them ideal for use in ship piping systems, heat exchangers, and offshore structures.

Meeting Industry Standards

Pipes used in marine environments must meet strict specifications. The ANSI B36.10/19 pipe chart provides critical data on outside diameter (OD) and wall thickness for various standard and stainless steel pipes, ensuring compliance with industry standards. By referencing these specifications, marine engineers and contractors can make informed decisions on the best materials for their projects.

Durable Solutions for a Demanding Industry

At Tork Systems, we provide high-quality copper-nickel and stainless steel piping solutions designed to withstand the harsh marine environment. Whether you're outfitting a new vessel or maintaining an existing system, choosing the right pipe material is key to long-term reliability and efficiency.
