Spiral plate heat exchanger is one kind of heat transmission equipment with higher heat transmission efficiency through spiral channel for heat transmission. It is widely used in chemical industry. Its working principal as the following: when two different fluid flow to the heat exchanger channels from both sides of tube wall; Two kinds of fluid contact upstream separated by tube wall. Hot fluid will transfer heat to tube wall, then to cold fluid to realize the structural characteristics. The fluid will reach turbulent flow condition at lower speed so it enhances the heat transmission. It is made of plate so it can reduce cost for large production. Materials: carbon or stainless steel Type: horizontal and vertical Standard: F= 40m2- F= 300m2 Four passage spiral plate heat exchanger is one kind of new structure developed and designed by the company for heavy flow and minor temperature difference working condition. Due to four fluid passage arrangement, the media can be heated and cooled down evenly in the passage so it can precisely control media outlet temperature. Advanced Welding Equipment Use dedicated stud welding machine imported from German to automatically weld distance column, the minimum thickness of base plate is 1.5mm and it can weld on clading materials and high alloy plate. The welding joint is plane and the two kinds of materials can be melted together so it has higher strength than common two points welding and the product quality is better. Unique Locking Structure Success lies in details, the company pays more attention for fine structure change. Unique locking structure makes it is more easy for spiral plate heat exchanger dismantal and assemble and convinent cleaning and maintenance. Aging Vibration Treatment During the welding process of heat exchanger, it causes a lot of stress which can be eliminated by heat treatment and high frequency aging vibration treatment for common carbon steel and stainless steel respectively; which makes product have better property and longer life. The company adopts the most advanced spiral plate auto production line to automatically level the plate, distance column, weld, roll, turnup, form and weld fluid passage; fully eliminate stress and check quality; which put the company's product quality and fabrication capacity to the first class in the world. After years of research and developing, it comes to eight serials products including hundreds of model which can provide solution for all kinds of special and complicated working conditions.
