In APAC's refineries and chemical plants, the material in a heat exchanger is a business decision as much as a technical one.
In the most corrosive service, hot chlorinated seawater, high chlorides and acidic streams drive material failures, unplanned downtime and unpredictable maintenance. Those costs land directly on profitability and production targets, and the most extreme service calls for a material engineered specifically for it.
Alleima HyperDuplex SAF® 2707 HD is engineered for exactly these conditions. It extends performance past conventional super-duplex, with a minimum PRE of 48 and corrosion resistance approaching that of nickel alloys, while keeping the economics of a duplex grade. For critical heat exchangers, that means the reliability of a premium alloy without the premium-alloy price.
Lower total cost of ownership
For a heat exchanger, cost is a lifecycle question, not a purchase price. SAF® 2707 HD lowers total cost of ownership in three ways that matter at portfolio level:
- Longer asset life: corrosion resistance that reduces tube failure cuts the frequency and capital cost of replacements.
- Higher uptime: fewer unplanned shutdowns protect production and the revenue tied to it.
- Lower maintenance load: less frequent inspection and repair frees capital and people for higher-value work.
The result is more predictable performance, and more predictable budgeting across the asset's life.
Adoption and supply
Alleima backs the material with qualified welding systems, a global supply chain that holds quality and availability steady across large projects, and direct access to materials specialists during selection and design. That matters most in fast-scaling markets like APAC and India, where project timelines leave little room for material risk.
As refining and chemical capacity expands across the region, the grade chosen for critical heat exchangers increasingly shapes both uptime and lifecycle cost. SAF® 2707 HD lets leadership teams lower that cost while raising reliability.
