Titanium is a superstar material, and our ASTM B338 tubes take full advantage of its properties. With a density of around 4500 kg/m³, they’re significantly lighter than stainless steel (8000 kg/m³) or copper-nickel (8900 kg/m³), making installation and handling a breeze. Their tensile strength, ranging from 900 to 1000 MPa, ensures they can withstand high pressures and stresses without buckling. But the real magic happens with their corrosion resistance. Titanium forms a natural oxide layer that shrugs off seawater, chlorides, and other corrosive agents, making it a perfect fit for harsh marine and desalination environments.
These tubes also resist biofouling, thanks to their smooth surfaces, which means less buildup of algae or marine organisms that can clog systems and reduce efficiency. They hold up at temperatures up to 400°C, ideal for thermal desalination processes like multi-stage flash (MSF) or multi-effect distillation (MED). Plus, their fatigue resistance ensures they can handle the constant vibrations and cyclic loads found in marine applications, from shipbuilding to offshore rigs.
Applications in Desalination and Marine Environments
Our ASTM B338 titanium tubes are a go-to for desalination plants, where they’re used in heat exchangers, condensers, and piping systems. Desalination processes like reverse osmosis (RO) and thermal distillation expose components to aggressive saline water and high pressures. Our tubes stand up to these conditions, reducing downtime and maintenance costs. Their long lifespan—often decades—makes them a cost-effective choice for plants aiming to maximize uptime and efficiency.
In marine environments, these tubes shine in offshore platforms, shipbuilding, and subsea equipment. They’re used in cooling systems, hydraulic lines, and structural components, where seawater corrosion is a constant threat. Their lightweight nature also helps reduce fuel consumption in marine vessels, while their strength ensures reliability in high-stress applications like deep-sea pipelines or wave energy converters.
Beyond desalination and marine, our titanium tubes find homes in other industries. In chemical processing, they handle corrosive fluids with ease. In power generation, they’re used in heat exchangers for their thermal stability. Even in aerospace, their strength-to-weight ratio makes them a favorite for hydraulic systems. But for us, desalination and marine applications are where they truly make a splash.

The desalination and marine sectors are booming, and our ASTM B338 titanium tubes are riding the wave. Global water scarcity is driving massive investments in desalination, with the market expected to grow from $15.9 billion in 2023 to $28.9 billion by 2030, at a CAGR of 8.9%. Titanium’s corrosion resistance and durability make it a top choice for plants aiming to meet rising demand for clean water, especially in regions like the Middle East and North Africa.
Marine industries are also evolving. Offshore wind farms, wave energy projects, and deep-sea exploration are pushing the need for materials that can survive harsh saltwater environments. Titanium’s ability to resist corrosion and fatigue makes it a standout for these applications. Add to that the rise of sustainable practices—titanium’s recyclability and long lifespan align perfectly with the industry’s push for eco-friendly solutions.
Advances in manufacturing, like seamless tube production and additive manufacturing, are making titanium more cost-effective. These innovations let us produce complex designs with less waste, lowering costs while maintaining quality. As regulations tighten on emissions and environmental impact, our lightweight tubes help marine vessels cut fuel use, supporting greener operations.
How We Stand Out
Our ASTM B338 titanium tubes aren’t just another product—they’re a testament to our commitment to quality and innovation. We manufacture to exacting standards, ensuring every tube meets ASTM B338 specifications for seamless and welded titanium. Our advanced production techniques, like precision forging and cold drawing, deliver tubes with superior dimensional accuracy and surface finish. This means better performance, less fouling, and easier integration into your systems.
We’re also big on customization. Need a specific diameter, wall thickness, or alloy grade like Ti-6Al-4V or Grade 2? We’ve got you covered. Our heat treatment processes, like annealing or stress relieving, optimize the tubes’ mechanical properties for your specific application. And our supply chain is rock-solid, with access to high-purity titanium sponge and rigorous quality checks to ensure consistency.
Compared to a typical competitor, our tubes offer tighter tolerances and better fatigue resistance, thanks to our proprietary manufacturing methods. We also prioritize sustainability, using energy-efficient processes and recycling titanium scrap to minimize waste. Our lead times are faster, and our technical support team works with you from design to delivery, ensuring you get exactly what you need. Whether it’s a small batch for a prototype or a large order for a desalination plant, we deliver on time and on spec.
