China Chemical Plant Heat Exchanger Manufacturer for Industrial Processing
Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) designs and fabricates heat transfer equipment for chemical plants, including shell-and-tube and plate heat exchangers in stainless and carbon steel, engineered to ASME, EN, and project specifications for industrial processing facilities.
Chemical processing demands exchangers that survive aggressive media, thermal cycling, and fouling, so equipment is selected and rated per duty rather than supplied as a catalogue item.
What Chemical Plants Require From Heat Exchangers
Process heating and cooling, condensation, evaporation, and heat recovery all rely on exchangers sized to the stream. Duties vary from clean sensible heating to fouling-prone reaction streams, so the configuration must follow the medium.
Heat Exchanger Types for Chemical Duty
- Shell-and-tube: Robust at high pressure and temperature, with removable bundles for cleaning.
- Plate: Compact and efficient for clean sensible heating and cooling.
- Air-cooled: Used where cooling water is scarce, rejecting heat to ambient air.
- Spiral: Wide-gap geometry suited to slurries and viscous streams.
Material and Corrosion Strategy
- 304 and 316L stainless: For corrosive organic and mild aqueous streams.
- Carbon steel with coating: For non-aggressive or lined service, with defined corrosion allowance.
- Medium matching: Material selection follows the specific chemical, not a default.
Engineering and Customization
- Thermal rating: Duty, temperatures, flow, and allowable pressure drop define the surface area.
- Fouling allowance: Velocity and cleaning access manage fouling in chemical streams.
- Custom geometry: Nozzle layout, bundle type, and supports adapt to the plant.
Quality and Code Compliance
- Codes: ASME, EN, and national standards as specified.
- NDT and test: Welding qualification, NDT, and hydrostatic test with full records.
Heat Exchanger Type Selection for Chemical Plants
| Type | Duty range | Fouling handling | Typical use |
|---|---|---|---|
| Shell-and-tube | High P / high T | Good (removable bundle) | Steam, reactors, utilities |
| Plate | Low to medium | Moderate | Sensible heating/cooling |
| Air-cooled | High temperature | Good | Cooling where water scarce |
| Spiral | Medium | Good (wide gap) | Slurries, viscous |
Conclusion
A chemical plant heat exchanger must be rated and material-matched to the stream. Center Enamel approach combines shell-and-tube and plate options in stainless or carbon steel, built to the project code with documented quality.
Project Case Study
| Project | Location | Industry | Equipment | Conditions | Materials |
|---|---|---|---|---|---|
| Hubei Chemical Process Vessels | China (Hubei) | Chemical | Steam distribution cylinder, condensate tank | 196 C / 1.2 MPa | S30408 |
Project Background
A chemical production facility in Hubei required high-temperature steam distribution and condensate recovery equipment as part of its heat-management system.
Project Requirements
- Steam distribution cylinder: DN200 x 2000 x 6 mm, S30408, 196 C, 1.2 MPa.
- Condensate tank: DN1200 x 3000 x 6 mm, S30408, atmospheric.
Technical Challenges
High-temperature steam and thermal cycling demanded stainless integrity and controlled welding to avoid long-term degradation.
Solution
S30408 fabrication with qualified welding procedures and pressure testing to specification delivered reliable heat-transfer-support equipment.
Project Outcome
The equipment was fabricated and delivered to the verified specifications above; no performance figures beyond documented data are claimed.
