In 1984, Zhang Zhiqiang, the founder of our company, participated as the only representative of the enterprise at that time in the development of the first polypropylene heat exchanger in the anti-corrosion department of Zhejiang University of Technology, solving the problem of polypropylene welding. From then on, the production and use of polypropylene equipment began in China
200 square meters, the larger the area, the greater the expansion force of the tube, and the higher the requirements for product design and quality. Few enterprises can produce 200 square meters of this type of heat exchanger, which reflects the quality and strength
Economical and cost-effective, with excellent anti-corrosion performance, but lower thermal conductivity than graphite and metals

The shell of the Yili series graphite modified polypropylene series tubular heat exchanger is a corrosion-resistant heat exchange equipment made of integrally reinforced polypropylene pipes, pure polypropylene sheets or modified polypropylene sheets, and graphite modified polypropylene heat exchange tubes, which are processed twice to form a complete plastic structure.
This product is a fixed tube sheet tube shell structure. The heat exchange tubes in the Yili brand SPGH series heat exchangers are specially designed graphite modified polypropylene thin-walled thin tubes, with a graphite content of 50% by weight.
This product not only maintains the advantages of corrosion resistance, lightweight, high-strength, and less prone to scaling in polypropylene equipment, but also greatly improves the heat transfer performance of the equipment. The total heat transfer coefficient of the equipment reaches 250~400KCal/m h ℃

Permissible temperature: -20~80 ℃ 0~120 ℃ (polypropylene)
Allowable pressure (at room temperature): Shell side ≤ 0.3Mpa Tube side ≤ 0.2Mpa
Permitted medium: Please refer to the relevant polypropylene corrosion performance data. If there is no data or other special requirements in the data, the test can be conducted according to GB11547-89.
The product models range from a minimum contact area of 5m2 to a maximum heat exchange area of 200m2, and can be customized according to customer requirements.
1. Excellent corrosion resistance, resistant to almost all inorganic media and most organic solvents
2. Both the tube and shell sides can pass through corrosive media.
3. Stable and good heat transfer performance.
4. Not prone to scaling.
5. Lightweight, compact, and easy to install and maintain.
6. Affordable price and cost
