What Makes Our Titanium Coil Tube Superior
The coil tube manufactured by Baoji Jucheng features a self-healing titanium dioxide (TiO2) protective layer. This passive film provides immunity to pitting corrosion in high-chloride environments where stainless steel 316L fails.
Our seamless processing eliminates weak points. Multiple cold bending techniques preserve material integrity while achieving tight radii. The annealed state ensures optimal ductility with elongation rates exceeding 20%.
Your applications benefit from titanium's 4.51g/cm³ density—45% lighter than steel. This weight advantage reduces structural load in marine installations and aerospace systems.
Heat transfer efficiency remains consistent throughout service life. Unlike copper alternatives that accumulate scale, our pickled and bright annealed surfaces resist fouling. This "clean surface effect" maintains thermal performance in seawater applications for 10-20 years compared to 2-4 years for cupronickel.

Quality Assurance You Can Trust
Every titanium coil tube undergoes 100% eddy current testing before bending. This non-destructive examination detects surface and subsurface defects that could compromise performance.
Hydrostatic testing at 1.5x design pressure confirms structural integrity. Pneumatic air-under-water testing identifies micro-leaks at weld points and bends.
Our dimensional inspection ensures ovality at bend points remains below 10%. Your equipment casings receive coils that fit precisely without field modifications.
Mill Test Certificates (EN 10204 3.1) verify chemical composition. Iron and oxygen content meet Grade 1 or Grade 2 specifications, ensuring the corrosion resistance you expect.

Coil Types for Your Application
Helical Coils maximize heat transfer surface within compact spaces. Your HVAC systems gain efficiency in shell-and-tube configurations.
Serpentine Coils provide uniform temperature distribution. Chemical processing equipment benefits from consistent flow patterns.
Pancake Coils deliver low-profile designs. Your space-constrained installations achieve thermal management without vertical limitations.
U-Coils simplify maintenance access. Marine condensers require easy inspection—our U-tube configurations deliver both performance and serviceability.

Industries We Serve
Your marine engineering projects benefit from our seawater-resistant coils. Desalination plants, offshore platforms, and ship condensers operate maintenance-free for decades.
Chemical processing facilities require corrosion immunity. Our tubes withstand high-chloride brine, acidic solutions, and alkaline environments without material degradation.
Aerospace applications demand lightweight strength. Our titanium solutions reduce system weight while maintaining pressure ratings for high-performance refrigerants like R410A.
Medical and pharmaceutical equipment requires biocompatibility. Grade 2 titanium provides non-reactive surfaces for sterile processing systems.
FAQ
Q: How does your coil tube perform compared to copper in heat exchange efficiency?
A: While copper offers higher thermal conductivity, our 0.6mm wall thickness and fouling-resistant surface maintain performance over time. After six months of operation, titanium often outperforms copper due to sustained clean surface conditions.
Q: What service life can I expect in seawater applications?
A: Properly manufactured coils deliver 10-20 years of reliable service in seawater environments, compared to 2-4 years for cupronickel alternatives when proper cleaning protocols are followed.
Q: Can your coils handle high-pressure refrigerants like R410A?
A: Yes. Our seamless construction supports high pressures. We perform burst pressure calculations per ASME VIII Div 1 standards, typically testing above 40 bar to ensure safety factors for R410A applications.
Q: Which grade is better for coil applications—Grade 1 or Grade 2?
A: Grade 2 serves as the industry standard for coil tubes. It provides higher strength than Grade 1 while maintaining excellent bendability for tight radii configurations.
Q: How should I clean the coil if fouling occurs?
A: Titanium's corrosion resistance allows chemical flushing with diluted hydrochloric acid solutions or mechanical backflushing without damaging the base metal—options unavailable for softer metals.
