1. Introduction — Redefining the Heating Surface Manufacturing Standard

In the world of boiler and heat exchange systems, performance begins with precision.
As a professional manufacturer of boiler tubes and serpentine coils, Shandong Boyu Heavy Industry Technology Group Co., Ltd. integrates automation, quality assurance, and advanced forming technology to deliver highly reliable heating surfaces for power, coking, and energy industries.

Boyu's continuous innovation and intelligent manufacturing capability ensure that every heat exchange component performs with efficiency, durability, and safety under extreme conditions.

2. Automated Production for Consistent Quality

At Boyu Industry, every serpentine tube and boiler coil is produced under a fully automated workflow that guarantees precision and consistency across each stage of manufacturing:

• CNC Beveling — Each tube end is machine-beveled to ensure accurate welding preparation and consistent geometry.

• Robotic Welding — Automated welding stations create uniform, full-penetration welds that eliminate defects and improve long-term reliability.

• Digital Radiography (DR) Testing — Every weld undergoes high-resolution non-destructive testing, ensuring zero leakage and perfect weld integrity.

• Precision Tube Bending — After testing, tubes are formed into serpentine shapes with high bending accuracy, ensuring optimal flow and heat transfer performance.

This integrated production line ensures every heating surface component meets ASME and international quality standards.

3. Leading Capacity — Asia' s Longest Serpentine Tube Forming Workshop

Boyu’s current serpentine tube production line can process tube diameters ranging from Ø32 mm to Ø60 mm, with total lengths up to 120 meters per piece.
Upon completion of the new manufacturing workshop, this capacity will extend to 150 meters, making it the longest serpentine tube forming facility in Asia.

This ultra-long forming capability reduces the number of weld seams, minimizes internal resistance, and enhances overall heat exchange efficiency — providing users with more durable and energy-efficient heating surfaces.

4. Applications Across Industrial Sectors

Boyu' s boiler tubes and serpentine coils are key components in a wide range of industrial systems:

• Coking Plants and CDQ Systems — Waste heat recovery and energy recycling.

• CFB Boilers and Power Stations — High-efficiency heating surfaces for combustion systems.

• Chemical and Metallurgical Equipment — Reliable tube coils for harsh process environments.

Each product is designed and manufactured in strict accordance with ASME U-Stamp certification, ensuring compliance with global safety and performance standards.

5. Quality, Strength, and Innovation

With decades of manufacturing experience, Boyu Industry has evolved into a benchmark enterprise in China’s heat exchange industry.
From automated production to advanced inspection systems, Boyu continues to push the limits of precision manufacturing — providing international customers with customized boiler tubes, serpentine coils, and complete heating surface assemblies that meet the highest technical standards.
