April 15, 2026 – A recent industry report highlighted that cracking tube failure is the leading cause of unplanned shutdowns in ethylene plants, with an average cost of $2.3 million per incident—including lost production, maintenance, and safety risks <superscript:2>. Many of these failures stem from using one-size-fits-all tubes that cannot withstand the unique operating conditions of individual plants, such as varying feedstocks, temperature fluctuations, and corrosive environments.
To solve this, [TaiGu] has expanded its custom cracking tube service, working directly with plant engineers to design tubes tailored to specific operational needs. Our team of metallurgists and process engineers conducts on-site assessments to analyze feedstock composition, furnace design, and operating parameters, then develops a customized tube solution that addresses the root causes of failure.
One recent success story comes from a European refinery that was experiencing frequent cracking tube failures due to high chloride levels in its cooling system—leading to stress corrosion cracking (SCC) . After our team conducted a thorough analysis, we recommended a custom alloy formulation with added molybdenum, which boosts resistance to chloride-induced SCC, along with an inner ceramic coating to further protect against corrosion.
Since installing the custom cracking tubes 12 months ago, the refinery has not experienced a single tube failure, reducing maintenance costs by 65% and eliminating unplanned shutdowns related to tube issues. “The difference is night and day,” said the refinery’s Lead Materials Engineer. “Working with [TaiGu] to get a custom solution meant we didn’t have to compromise on performance or waste money replacing failed tubes.”
