YUHONG GROUP Conducts Pre-Assembly Testing of 50+ API 661 Air-Cooled Heat Exchangers to ASME Standards

YUHONG HOLDING GROUP is pleased to report that pre-assembly testing is now underway for a substantial batch of air-cooled heat exchangers, manufactured in full compliance with the API 661 standard. The current order covers 9 tag numbers and more than 50 individual units, underscoring our proven ability to execute high-volume, code-compliant thermal equipment projects on schedule and to exacting specifications.

• Air Tightness / Leak Testing — confirming that all joints, tube-to-tubesheet connections, and header seals remain leak-free under controlled pressure.
• Performance Testing — validating heat transfer capacity, airflow distribution, and pressure drop against the API 661 design requirements.
• ASME-Mandated Inspections — covering material traceability, weld examination, and dimensional verification throughout the manufacturing process.

All testing procedures are executed in strict accordance with ASME code requirements, ensuring that every air cooler leaving our workshop meets the reliability standards demanded by refineries, petrochemical plants, and power generation projects worldwide.

This order is a direct reflection of our high-level manufacturing strength. YUHONG HOLDING GROUP operates three ASME-certified facilities across Jiangsu Province — in Jiangyin, Jinjiang, and Yancheng — spanning a combined 184,000 square meters. With 730 skilled workers and an annual production capacity exceeding 3,600 units, we are fully equipped to handle complex, multi-tag, high-quantity orders while maintaining consistent quality and reliable on-time delivery.

Managing 9 tag numbers and 50+ units within a single project demands disciplined production planning, synchronized fabrication across multiple workshops, and rigorous quality gates at every stage. The smooth progress of this pre-assembly phase demonstrates exactly that capability — the ability to scale precision engineering without compromising on code compliance.

Since our founding in 1990, YUHONG has served 3,000+ customers across more than 80 markets, with an export share of 80–90%. Our product portfolio covers heat exchangers, pressure vessels, fired heaters, cooling towers, and air coolers — all delivered as complete, code-compliant thermal solutions backed by decades of engineering experience.
