Chemical & Petrochemical Heating Solutions
Process heating for reactors, storage tanks, pipelines and heat-exchange systems
Industry Characteristics & Heating Challenges
Chemical media often demand more from materials and sealing than from power. Acid and caustic solutions call for titanium, 316L or PTFE-sheathed elements; hazardous areas need explosion-proof terminal housings and the correct temperature class; high-viscosity products require attention to element surface temperature and coking. Houyi Technology provides complete solutions for reactors, tank tracing, distillation reboilers and pipeline freeze protection, from material selection to explosion-proof certification.
Typical Applications
- Reactor jackets and internal heating
- Tank freeze protection and insulation
- Pipeline tracing and crystallization prevention
- Acid and caustic solution heating
- Thermal oil circulation systems
Questions We Ask During Selection
- Q1Exact composition and concentration of the medium, and whether it is corrosive, scaling or prone to polymerization.
- Q2Whether heating is intermittent or continuous, and the required heat-up time.
- Q3What explosion-proof zone the site falls into, and how gas group and temperature class are classified.
- Q4Material, pressure rating and available installation opening size of the vessel or pipe.
- Q5Whether the power supply can handle the high-power load, and whether soft start or power regulation is needed.
- Q6Maintenance cycle and cleaning method, which determine whether the structure is withdrawable or fixed.
Within the same industry, heating requirements can vary greatly between processes. Sending us your specific operating conditions saves more time than selecting against a catalog.
