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

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.

What is a tubular exchanger? A tubular heat exchanger is used to warm or cool a product by exchanging heat between the process fluid and a service fluid,which is typically water, ice water, glycol or steam. The hot or cold service fluid flows around the tubes within the tubular heat exchanger and heat is transferred between the product and the media.
