1. What is the material selection standard for pressure vessels? Preferred: 304/316L stainless steel or Q245R carbon steel, compliant with ASTM A516/A240 and pressure vessel codes (ASME, EN13445).
2. How is the steam boiler heat exchanger designed for durability? By using corrugated tubes, wave finned structures, and high-nickel alloys for aggressive environment resistance and turbulent flow for optimized heat exchange rate (>95%).
3. What size range do leading manufacturers cover? From 24kW domestic to >7MW industrial scale. Custom designs up to 25MW/h available for industrial districts.
4. What are the installation standards for steam boilers? Installations must comply with ASME Section I/IV, ISO 3834, and local codes. Full hydrotest, electrical insulation, and grounding are mandatory.
5. How is warranty coverage structured? Typically: 2 years on pressure body, 1 year on electrical system, with lifetime support and spare parts supply.
6. What is the typical delivery time for custom electric steam boilers? 18–32 working days ex-works for standard and customized units, plus international transit per Incoterms.
7. How do electronic thermostat systems improve performance? By providing real-time temp/pressure measurements, optimizing response, and integrating with building management or DCS for remote operation and efficiency tracking.
