0.5-2.5MPa Pillow Plate Heat Exchanger Concave And Convex Plates Fully Welded Process

Concave and convex plates with fully welded process for superior heat transfer performance

The pillow-shaped plate heat exchanger features a unique concave and convex plate design where adjacent plates are welded together through a fully welded process to form closed three-dimensional flow channels. This innovative structure enables hot and cold fluids to flow in cross-flow patterns on both sides of the plates, with the concave and convex surfaces forcing fluid turbulence that effectively disrupts boundary layers, resulting in over 30% higher heat transfer efficiency compared to traditional flat plate heat exchangers.

Ruiding has established the Jiangsu Province Clean Incineration Resource Engineering Technology Center and the Key Laboratory of the JICUI-Ruidings Joint Innovation Center. Our laboratory is equipped with advanced detection equipment including ICP inductively coupled plasma emission spectrometry, atomic absorption spectrophotometry, atomic fluorescence spectrophotometry, high-temperature combustion ion chromatography analyzer, high-temperature combustion rate analyzer, and rapid equilibrium flash point tester. We possess capabilities for heavy metal analysis, elemental analysis, off-gas calorific value analysis, ash melting point detection, incineration boiler water quality testing, sewage analysis, and volatile waste analysis.

Ruiding specializes in engineering, fabrication, construction, and commissioning services for industrial waste combustion treatment systems including thermal oxidizers (incinerators), heat recovery systems (boilers), pressurized vessels, flue gas treatment systems (DeSOx, DeNOx), and plate heat exchangers. We hold Environmental Protection Engineering Class 2 EPC certification, ASME Certificate, Class A boiler manufacturing license, Class A boiler installation and Revamping & Maintenance certificate, A2 designing and manufacturing certificate for pressure vessels, and GC1, GC2 pressure pipeline designing & construction certificates. With over 250,000 square meters of building area and nearly 300 professional technical staff, we have completed over 500 engineering projects across various domestic and international industries.
