Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer established in 2015 with a factory spanning 10,000–30,000 square meters and over 300 dedicated employees, presents our Semi-Welded Plate Heat Exchanger for Environmental Water Treatment. Designed to withstand demanding conditions of 1.6 MPa and 180°C, this heat exchanger utilizes high-performance PTFE gaskets to deliver exceptional corrosion resistance and thermal efficiency. Our advanced semi-welded construction ensures leak-free operation, making it an ideal solution for wastewater treatment, chemical processing, and other environmentally sensitive applications. With an annual export value exceeding US$10 million and a global presence across North America, Europe, and Asia, we combine engineering expertise with reliable manufacturing to provide a product that meets the highest standards of quality and durability.
Key Features & Technical Specifications
- Robust Semi-Welded Design: The plate pairs are laser-welded to eliminate inter-plate leaks, while the outer gaskets (PTFE) provide easy maintenance and replacement. This hybrid design offers the best of welded and gasketed heat exchangers.
- High Pressure & Temperature Capability: Rated for 1.6 MPa and 180°C, suitable for demanding industrial processes where traditional gasketed units may fail.
- PTFE Gaskets: Excellent chemical resistance against acids, alkalis, and solvents; ideal for aggressive fluids in water treatment.
- Compact Footprint: High heat transfer coefficient (up to 6000 W/m²·K) reduces space requirements by up to 50% compared to shell-and-tube heat exchangers.
- Easy Maintenance: The semi-welded design allows access to the service side for cleaning while the process side remains sealed, reducing downtime.
- Flexible Configuration: Available in multiple plate materials (SS304, SS316L, titanium) and connection sizes (DN25–DN150) to match specific system requirements.

Advantages for Environmental Water Treatment
- Corrosion Resistance: PTFE gaskets and optional titanium plates ensure long service life even when handling corrosive wastewater, brine, or acidic streams.
- Energy Efficiency: The high turbulence created by the plate pattern reduces fouling and maintains consistent performance, lowering energy consumption by up to 20% compared to traditional heat exchangers.
- Sanitary Design: Smooth surfaces and full drainability meet hygiene standards for food-grade water treatment or pharmaceutical applications.
- Scalability: Modular design allows easy addition or removal of plates to adjust capacity without replacing the entire unit.

Frequently Asked Questions (FAQ)
-
What is the difference between a semi-welded and a fully welded heat exchanger?
A semi-welded design uses laser-welded plate pairs on the process side and gaskets on the service side, offering a balance of leak tightness and maintainability. Fully welded units are completely sealed but harder to service. -
Can this heat exchanger handle chlorinated water or brine?
Yes, with PTFE gaskets and appropriate plate material (e.g., titanium or SS316L), it can withstand chlorinated water and various brine solutions without corrosion. -
What is the maximum number of plates I can add?
The frame is customizable; typical configurations range from 10 to 300 plates. Consult our engineering team for your specific flow and duty requirements. -
How do I clean the heat exchanger if fouling occurs?
The service side (gasketed) can be opened for mechanical cleaning, while the process side (welded) can be cleaned chemically or via backflushing. Detailed cleaning procedures are provided in the manual. -
Do you provide frame materials other than carbon steel?
Yes, stainless steel frames are available upon request for highly corrosive environments. -
What certifications does the product hold?
Our manufacturing facility is ISO9001, ISO14000, OHSAS18001, and HACCP certified. The heat exchanger itself can be designed to meet ASME, PED, or other codes as required. -
Can I get a sample or test unit before bulk order?
Yes, we offer small-scale prototypes for performance testing. Minimum order quantity is negotiable for trial orders. -
What is the typical lead time?
Standard lead time is 4–8 weeks depending on configuration and order volume. Rush orders are possible with prior arrangement.
