Against the backdrop of 2025–2026 trends, chemical companies are operating in a complex, yet technologically very interesting environment. On the one hand, the chemical industry is entering 2026 with much more cautious expectations than at the beginning of the previous forecasting cycle. According to the updated mid-year assessment by the American Chemistry Council, global chemical production volumes may grow by only 0.5% in 2026 due to production disruptions in the Middle East and in certain regions of Asia and Europe; at the same time, growth is expected to recover to 3.2% in 2027 once supply chains normalize.
On the other hand, pressure on margins, energy efficiency, safety, and environmental performance is forcing companies to rethink their engineering decisions. At the center of this transformation are materials capable of operating where conventional steel quickly loses service life. Among the most important of these are nickel alloys and tubes made from nickel alloys.
Why the Chemical Industry Needs Nickel Alloys
Chemical production is an environment of constant testing for equipment. Pipelines, heat exchangers, reactors, scrubbers, columns, vessels, and fittings come into contact with acids, alkalis, chlorides, high temperatures, pressure, and abrasive flows. A mistake in material selection can mean not just repairs, but an emergency shutdown, a leak of hazardous substances, product loss, or an environmental incident.
Nickel alloys are valuable because they combine several properties:
- high corrosion resistance in acidic, chloride-containing, and high-temperature environments
- stable mechanical strength across a wide temperature range
- resistance to pitting corrosion and stress corrosion cracking
- longer service life in critical components
- the ability to work with aggressive reagents where standard steel grades are economically or technically unsuitable
The Nickel Institute explicitly states that nickel-containing steels and nickel alloys are widely used in the chemical and petrochemical industries due to their corrosion resistance in aqueous, gaseous, and high-temperature environments.
Nickel-Based Alloy Tubes: Not Just a Pipeline, but an Element of Process Safety
In the chemical industry, “nickel tubes” usually do not mean tubes made of pure nickel, but tubes made from nickel alloys: for example, Ni-Cr-Mo, Ni-Cu, Ni-Mo, or highly alloyed nickel-containing steels. Such tubes are used in processes where maximum resistance to aggressive environments is required.
Typical applications for nickel tubes include:
Transfer of acids and chloride-containing media. In fertilizer production, organic synthesis, chlorinated organics, and specialty chemicals, pipelines often come into contact with sulfuric, hydrochloric, and phosphoric acids, or mixtures containing chlorides. In such conditions, nickel alloys help reduce the risk of through-wall corrosion.
Heat exchangers and evaporators. High temperature accelerates corrosion. That is why nickel alloys are used in heat-exchange equipment where heat, pressure, and aggressive chemistry are combined.
Scrubbers and gas-cleaning systems. Gas treatment units often operate with acidic condensates, chlorides, and sulfur-containing compounds. Such units require materials with high resistance to localized corrosion.
Multiproduct chemical plants. At facilities where the same line handles different reagents, material versatility becomes a competitive advantage. Ni-Cr-Mo-type alloys can provide a broader “safety window” across different media.
What Market Forecasts Show
Demand for nickel alloy tubes is growing alongside the development of petrochemicals, energy, hydrogen infrastructure, nuclear power, carbon capture systems, and highly specialized chemical production.
According to a market forecast by Dataintelo, the global nickel alloy pipe market was valued at approximately USD 4.8 billion in 2025 and may grow to USD 8.1 billion by 2034, representing a compound annual growth rate of about 6% in 2026–2034. The same forecast identifies chemical and petrochemical processing as the second-largest application area, accounting for around 26.3% of the market after the oil and gas sector.
Seamless tubes deserve special attention. They are more expensive, but in critical environments they offer an advantage due to the absence of a weld seam — a potential weak point under high pressure, temperature, or corrosive load. According to market estimates, seamless nickel alloy tubes accounted for around 62.4% of the segment in 2025.
For the chemical industry, this means one simple thing: the market is moving not only toward cheaper materials, but toward materials with predictable service life, lower accident risk, and better compatibility with harsh operating conditions.
Where Nickel Alloys Create New Opportunities
1. More aggressive processes without rapid equipment wear. Modern chemistry is working with increasingly complex environments: concentrated acids, chloride systems, metal-based catalysts, and high-temperature reactions. Nickel alloys allow engineers to design installations for such processes with a greater reliability margin.
Similar tasks can be solved using nickel alloys available in the Centravis portfolio. In particular, the company produces seamless tubes from corrosion-resistant nickel grades for heat exchangers, furnaces, and equipment used in the chemical and petrochemical industries. Such materials are suitable where pipelines and heat-exchange surfaces come into contact with acids, chlorides, hot gases, or other aggressive environments: they help extend equipment service life, reduce the risk of localized corrosion, and decrease downtime associated with repairs or tube replacement.
2. Less downtime and a lower lifecycle cost. Nickel alloys are usually more expensive at the procurement stage. But for a chemical plant, what matters is not only the price of the tube, but the total cost of ownership: installation, shutdowns, repairs, replacement, product losses, accident risk, and disposal of damaged components.
If a cheaper material requires frequent repairs or corrodes quickly, it may turn out to be more expensive than a nickel alloy over the full lifecycle. This is especially relevant for continuous production facilities, where every hour of downtime carries a high cost.
3. Safer handling of hazardous substances. In the chemical industry, a pipeline is not an auxiliary element, but part of the industrial safety system. Corrosion failure can lead to a leak of acid, toxic gas, or flammable product. Using corrosion-resistant nickel alloys in critical sections reduces the likelihood of such scenarios.
This is especially important against the backdrop of aging industrial infrastructure in many countries and increasingly stringent requirements for safety, transparency, and environmental responsibility.
4. Support for new “green” technologies. The chemical industry is both a major source of emissions and a supplier of materials for the energy transition. Estimates suggest that the sector accounts for approximately 5–6% of global greenhouse gas emissions. Therefore, decarbonizing the chemical industry requires not only new energy sources, but also new materials for equipment.
Nickel alloys can play an important role in hydrogen production, low-carbon methanol, CO₂ capture systems, waste processing, gas cleaning, and high-temperature processes. Where the environment is simultaneously hot, corrosive, and technologically critical, pipeline material directly affects the stability of the “green” process.
Environmental Performance: How Tube Materials Affect Production Sustainability
The environmental performance of a chemical plant is often viewed through the lens of energy, raw materials, and emissions. But equipment materials also matter.
First, durable tubes reduce replacement frequency. This means less metal waste, fewer repair operations, fewer shutdowns, and fewer indirect emissions associated with the production and logistics of new components.
Second, corrosion-resistant materials reduce the risk of leaks. For chemical production, this is critical: even a small leak of acid, alkali, or a toxic intermediate product can have serious consequences for soil, water, personnel, and the company’s reputation.
Third, nickel alloys help enable cleaner technologies. Gas-cleaning systems, scrubbers, heat exchangers for heat recovery, recycling units, and low-carbon chemical processes often require materials capable of withstanding aggressive environments. Without such materials, many environmental solutions become less reliable or too expensive to operate.
At the same time, it is important to remember that nickel itself has an environmental footprint at the mining and production stage. Therefore, a responsible approach does not mean using expensive alloys everywhere without control, but rather precise engineering selection: nickel alloys should be used where their durability, safety, and corrosion resistance genuinely reduce risks and the full lifecycle cost.
Conclusion
In 2025–2026, the chemical industry is operating amid slower growth, regional competition, high energy costs, and pressure to undergo environmental transformation. This means strategic advantage goes to companies that design more durable, safer, and more efficient production systems. Nickel alloys and nickel alloy tubes are becoming one of these tools: they make it possible to work with aggressive environments, improve pipeline reliability, reduce accident risks, support new environmental technologies, and optimize the lifecycle cost of equipment.
