What is a spiral wound tube heat exchanger? Spiral wound tube heat exchanger, also known as threaded tube heat exchanger, turbulent heat exchanger, double bellows heat exchanger. It is a new type of shell and tube heat exchanger. Each heat exchange tube is evenly wound in the heat exchanger shell according to a certain rule. According to the different interface structure, it is divided into L type and Y type. According to whether it can be disassembled, it can be divided into detachable type and non-detachable type. Type: Y type,T type,detachable,double tubesheet, cold trap, gas-liquid separation etc. Material:austenitic stainless steel 316L, double-phase stainless steel 2205, 2507, pure titanium, zirconium, Hastelloy alloy, etc. Tube type:Spiral wound tube/parallel tube/U type tube Tube: �¦8ï¼?�¦10ï¼?�¦12, �¦14ï¼?�¦16,�¦19ï¼?�¦25etc. Maximum working pressure:4Mpa Heat exchanger area:0.1-1000 square meters working temperature:-20-300 degree celsius (customizable) Applicable fluids:steam, circulating water, frozen brine, glacial refrigerant, glycol;. installation type:Horizontal/Vertical Function:Heater, cooler, condenser, evaporate, distillation, rectification Application:Distillation reflux system, concentration system, distillation system, waste gas and heat recovery system, traditional Chinese medicine extraction system, instantaneous sterilization at high temperature, CIP cleaning system, civil HVAC system,heating and cooling of process materials Customization:According to the technical requirements of customers, we can accurately customize the winding tube heat exchangers with various spacing. Package:Standard export wooden box,can be packaged according to customer requirements. Advantages: 1.High heat transfer coefficient :Unique wound tube bundle optimizes the flow state of the fluid on both sides 2.Long service life spiral :The elastic tube bundle can effectively absorb stress and vibration, prolong the service life of the heat exchanger 3.Low scaling tendency :Thereâ??s no dead angle in the heat exchanger, and the tube side and shell side can be emptied; the high flow rate design of the shell side can effectively reduce the probability of scaling on the surface of the heat exchange tube 4.small floor space: Compact structure,about 1/5 of the traditional heat exchanger 5.Low operating cost : Under heat conditons ,it can save the steam ;under the condensation conditions,it can improve the recovery rate. � Shandong Qinglei Environmental Technology Co.,Ltd is an equipment manufacturer integrating design, production and assembly.

Lightweight Mineral Wool Board Production Line Equipment Production Line Equipment Introduction Lightweight Mineral Wool Board Features Mineral wool board mining high quality mineral wool as the main raw material, 100% free of asbestos, acicular dust will not appear, will not enter the body through the respiratory tract, harmless to the human body. The use of composite fiber and mesh base coating, greatly improving the impact resistance, deformation resistance. Mineral wool internal structure was three-dimensional cross-mesh structure, adequate internal space, solid structure, greatly improving their ability to absorb noise and noise than ordinary mineral wool board sound absorption increased by 1 to 2 times. Internal moisture and auxiliary agents to add moisture, both increasing the surface fiber resistance, effective binder stability, to maintain plate strength, and can regulate indoor humidity and improve living environment. Nano-antibacterial agent flooding the interior of the plate, can effe ctively mold, sterilization, antibacterial regeneration, greatly improving the scope of application, it can be applied to have the requirements of antibacterial, sterile aseptic environment.
