- Materials: Pressure vessels use Q245R (Chinese standard) or ASTM A516 for high-temperature, anti-corrosion performance; piping: 20# seamless steel.
- Manufacturing: Automated CNC cutting, argon arc welding, and precise machining ensure dimensional accuracy & excellent sealing.
- Inspection: Each thermal oil boiler undergoes NDT (non-destructive testing), hydrostatic test, and X-ray inspection—above ISO 9001 quality compliance.
- Surface/Corrosion: Anti-rust coatings (zinc-rich epoxy or ceramic), thick insulation (rock wool ≥ 80mm), and stainless casing prolong service life (15-20 years).
- Superior Efficiency: Modern thermal oil boiler units reach up to 94.2% efficiency (condensing models), significantly reducing operating costs.
- Low Pressure, High Temperature: Safely achieve >320°C without the explosion risk of steam systems; meets API and ASME process safety standards.
- Precision Control: PLC+HMI automated controls (Siemens, ABB) enable precise outlet temp (±1.5°C) and real-time fault monitoring.
- Corrosion Resistance: Advanced internal coating, anti-fouling tube designs, and intelligent soot-blowing enhance lifespan, especially in harsh chemical environments.
