As a trusted manufacturer with over 25 years of experience (since 1998), Anping County Boli Hardware Wiremesh Products Factory proudly presents our Semi-Welded Pillow Plate Heat Exchanger. Crafted from premium 304 stainless steel with a thickness of 1.8mm, each unit is pressure tested to 12 Bar and designed to operate seamlessly on both 50Hz and 60Hz power systems. This heat exchanger delivers reliable performance for demanding industrial thermal management, combining efficient heat transfer with robust construction.
Our semi-welded design ensures that the pillow plates are securely joined, minimizing leakage risks while maintaining excellent thermal conductivity. The 304 SS material offers superior corrosion resistance, making it suitable for a wide range of media including water, oils, and mild chemicals. Whether you need to heat or cool process fluids, this exchanger provides a compact and durable solution that reduces maintenance downtime.
Key features and benefits include:
- Robust Semi-Welded Construction: The pillow plates are welded at the edges, creating a strong seal that prevents cross-contamination between media. This design also allows for easy cleaning and inspection.
- High-Pressure Capability: Each unit is individually pressure tested to 12 Bar, ensuring leak-free operation under working pressures up to 10 Bar (recommended maximum). The 1.8mm thick plates provide structural integrity even in fluctuating temperature conditions.
- Versatile Power Compatibility: The heat exchanger is compatible with both 50Hz and 60Hz electrical systems, making it ideal for international installations. Motors and pumps (if applicable) can be configured accordingly upon request.
- Excellent Heat Transfer Efficiency: The pillow plate geometry creates turbulent flow paths, enhancing heat transfer coefficients up to 30% higher than traditional shell-and-tube designs. This results in smaller footprint and lower energy consumption.
- Corrosion-Resistant 304 Stainless Steel: 304 SS offers good resistance to oxidation and many organic/inorganic chemicals. It is suitable for food processing, pharmaceutical, chemical, and HVAC applications.
- Customizable Dimensions and Connections: We offer various sizes, port configurations (flanged, threaded, or welded), and optional insulation. Please contact us with your specific requirements.

The semi-welded construction offers a distinct advantage over fully welded or gasketed designs: it provides a secure seal for one fluid side while allowing the other side to be easily opened for cleaning. This is particularly beneficial in applications where hygiene and maintenance are critical, such as dairy, beverage, and pharmaceutical industries.

Frequently Asked Questions
-
Q: What fluids can be used with this heat exchanger?
A: The 304 SS material is compatible with a wide range of fluids including water, steam, oils, glycols, and mild chemicals. For aggressive media, we recommend checking compatibility or requesting a higher-grade material (e.g., 316L). -
Q: What is the maximum operating temperature?
A: The recommended maximum continuous operating temperature is 200°C, depending on the pressure and media. Higher temperatures may be possible with design adjustments – please consult our engineering team. -
Q: Can the dimensions be customized?
A: Yes, we offer custom sizes for length, width, and number of plates. Please provide your required flow rate, pressure drop, and thermal duty for a tailored solution. -
Q: How is the unit tested before delivery?
A: Each heat exchanger is hydrostatically pressure tested to 12 Bar on the 304 SS side. We also perform visual inspection and dimensional checks. A test certificate is available upon request. -
Q: What is the lead time for standard orders?
A: Standard lead time is 15–25 working days, depending on quantity and complexity. Custom orders may require additional time. We work with our logistics partners to ensure timely delivery. -
Q: Is the product suitable for outdoor installation?
A: Yes, 304 SS provides good atmospheric corrosion resistance. However, for harsh outdoor environments (marine, coastal), we recommend additional protective coatings or use of 316L. We can advise based on your location. -
Q: Do you offer spare parts or after-sales support?
A: Yes, we provide spare gaskets (if applicable), replacement plates, and technical support. Our sales team can assist with any operational issues. -
Q: What packaging is used for export?
A: Each heat exchanger is securely packed in wooden crates or plywood boxes, with foam padding to prevent damage during transit. We can also arrange custom packaging as per your requirements.
With over two decades of manufacturing expertise and a strong export track record, Anping County Boli Hardware Wiremesh Products Factory is your reliable partner for heat exchange solutions.
