3. Manufacturing Process Flow and Quality Assurance

Key Steps in Gas Fired Thermal Oil Boiler Manufacturing:

Raw Material Inspection: Select high-strength seamless carbon steel / alloy steel (e.g. 20# steel) tested for purity and wall thickness (per ISO 9328-2).

Pressure-bearing Parts Forming: Uses CNC plasma cutting, automatic submerged arc welding, and hydraulic rolling to shape pressure vessel parts with high precision.

Coil Winding & Assembly: Helical finned tube coil wound automatically for optimal heat transfer; ensures uniform fluid velocity and low fouling.

Welding & Non-destructive Testing: Advanced robotic welding per ASME IX, 100% radiographic and ultrasonic NDT to ensure zero micro-cracks/leaks.

Paint & Anti-Corrosion: Multi-layer epoxy + high-temp silicone painting per ANSI/NACE MR0175 standards, TUV test verified.

Final Assembly & Functional Testing: Pneumatic and hydrostatic tests (1.5×design pressure), stack emission & NOx testing, trial ignition and controls check.

Inspection & Certification: All products pass ISO 9001, EN 10204 3.1 material traceability, and third-party witness (SGS/TUV/BV) before leaving the facility, ensuring a typical service life of 20+ years (SteamForum, 2022).

ASTM standard reference: "ASTM A106/A106M for seamless pressure pipe"; ISO 14001 for environmental performance.

Q2: What are typical installation and safety standards?

A: Installation per EN 12952/ASME Sec I. Integral multi-layer insulation ensures surface temperature <60°C. Safety valves, flow and temperature interlocks, and flameout shutdown systems certified by CE/UL.

Q3: How is the thermal efficiency calculated?

A: By dividing effective heat output by supplied fuel input, as measured under full-load (ISO 9127 standard fuels), for gas fired thermal oil boiler typically 92–97%.

Q4: What is the recommended max working temperature?

A: Generally up to 350°C for standard thermal oil (e.g. Mobiltherm 603); specialty fluids and high-alloy coils up to 400°C are possible in custom units.

Q5: What is a “multi-pass coil structure” and its benefit?

A: Multi-pass (2~4) structure ensures flue gas repeatedly traverses heating coil, maximizing heat recovery and further increasing efficiency and uniformity.

Q6: How is emission controlled?

A: Low-NOx premix or staged combustion burners, O2 trim, and in some cases, flue condensing heat exchangers, ensuring both NOx <30mg/Nm³ and CO <50mg/Nm³ (EPA/Euro V compliance).

Q7: Can the gas fired thermal oil boiler be monitored or controlled remotely?

A: Yes, with modern PLC/SCADA systems and IoT modules, full 24/7 remote monitoring and fault diagnostics are available (Siemens, Schneider, etc.).
