The aerial view clearly reveals the scale and ambition behind Boyu's Phase III Project, a major expansion currently under steady construction. Upon completion, the project will further integrate with Boyu’s existing manufacturing facilities and mark a significant milestone in the company’s long-term development strategy.

According to the current construction schedule, the Phase III Project is expected to be completed by March of next year. Once fully operational, it will become the largest serpentine tube production base in Asia, significantly enhancing Boyu’s manufacturing capacity for high-end boiler components and heat transfer equipment.

An Extraordinary Workshop Designed for Extraordinary Lengths

One of the most striking features of the Phase III Project is its ultra-long production workshop, with a total length of approximately 800 meters. This exceptional scale enables Boyu to achieve something rarely seen in the industry:

• Integrated manufacturing of serpentine tube bundles up to 220 meters in length

• A capability that far exceeds conventional boiler tube and tube bank design standards

In typical boiler applications, the effective length of individual tube circuits or tube banks is usually limited to several tens of meters, constrained by thermal expansion, pressure drop, flow distribution, and installation considerations. Designs exceeding 80 meters are already uncommon, while lengths beyond 100 meters are rarely adopted in standard boiler engineering.

Boyu’s ability to manufacture 220-meter serpentine tube bundles as a single integrated unit is therefore not driven by code requirements, but by advanced manufacturing capability, facility scale, and process control.

Beyond Size: Engineering Value and Practical Benefits

The significance of ultra-long serpentine tube manufacturing lies not only in size, but also in engineering performance and project execution advantages:

• Substantially reduced field welding, minimizing installation risk

• Improved structural integrity, thanks to fewer joints and transitions

• Enhanced reliability under high-temperature and high-pressure operating conditions

• Greater suitability for large-scale boilers and waste heat recovery systems, especially in demanding industrial and power generation applications

By enabling the delivery of large tube bundles in a more complete and integrated form, Boyu helps customers simplify on-site installation, shorten construction schedules, and improve overall system reliability.

A New Platform for Global Projects

With the completion of the Phase III Project, Boyu will establish a powerful combination of scale, technical capability, and delivery capacity in the serpentine tube sector. This expansion not only strengthens Boyu’s position in the domestic market, but also provides a solid manufacturing foundation for large-scale international projects.

What begins as an aerial view today will soon become a new manufacturing landmark for Asia’s boiler and heat exchange industry, supporting customers worldwide with advanced solutions for high-performance thermal systems.
