(1) the spiral wound tube heat exchanger is highly efficient and saves energy (steam). Internal unique reverse winding spiral coil structure, heat exchange in a current way, make fully condensing steam in the heat exchange tube bundle, do not need a second heat exchange, so it can save a lot of steam; (2) spiral wound tube heat exchanger is stainless steel welding, it can bear high temperature and high pressure. Because the heat exchange tube bundle and shell are all made of stainless steel material, with uniform expansion coefficient, the maximum pressure is1.6 MPa, the highest heat-resistant is 400 â??,it will not cause deformation of the heat exchanger because of pressure and temperature; so there is no need to prepare the equipment to reduce the pressure and temperature. (3) its structure is compact, with small size, saving infrastructure investment; Lightweight and easy to install, the equipment can be connected directly to the pipe, reducing installation cost. (4) the heat exchanger with Michael's (OWEN) turbulent buffeting frequency standard principle, the heat exchange tube bundle adopts the minimum clearance design, effectively eliminates the turbulent chattering phenomenon, prolongs the service life of the heat exchanger. (5) the heat exchanger is low in scale with a low maintenance cost, with unique structure, unique surface treatment technology, and on both sides of the counterflow heat exchange medium, not only improving the integrated heat transfer coefficient but also with self-cleaning function and low scale tend. The method of chemical descaling can be used to clean the heat exchanger, which can save time, power, cost and effect.
Shell and tube heat exchangers consist of a series of tubes. One set of these tubes contains the fluid that must be either heated or cooled. The second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required. A set of tubes is called the tube bundle and can be made up of several types of tubes: plain, longitudinally finned, etc. Shell and tube heat exchangers are typically used for high-pressure applications (with pressures greater than 30 bar and temperatures greater than 260°C). This is because the shell and tube heat exchangers are robust due to their shape. Features 1. Tube diameter: Using a small tube diameter makes the heat exchanger both economical and compact. However, it is more likely for the heat exchanger to foul up faster and the small size makes mechanical cleaning of the fouling difficult. 2. Tube thickness: The thickness of the wall of the tubes is usually determined to ensure: a. There is enough room for corrosion b. That flow-induced vibration has resistance c. Axial strength d. Availability of spare parts e. Hoop strength (to withstand internal tube pressure) f. Buckling strength (to withstand overpressure in the shell) 3. Tube length: heat exchangers are usually cheaper when they have a smaller shell diameter and a long tube length. Thus, typically there is an aim to make the heat exchanger as long as physically possible whilst not exceeding production capabilities. 4. Tube pitch: when designing the tubes, it is practical to ensure that the tube pitch (i.e., the centre-centre distance of adjoining tubes) is not less than 1.25 times the tubes' outside diameter. 5. Tube corrugation: this type of tubes, mainly used for the inner tubes, increases the turbulence of the fluids and the effect is very important in the heat transfer giving a better performance .
