Spiral Wound Tube Heat Exchanger

Supplier From China
Dec-11-20

(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.

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.

Design Features & Benefits
The spiral plate heat exchanger is made by rolling two long metal plates around a center core to form two concentric spiral flow passages, one for each fluid. The plate edges are welded shut so that each fluid stays within its own passage and there is no flow bypassing or intermixing. Channel plate width and spacing (gap between plates) are optimized for the specified duty, maximum heat transfer, and ease of access. The plate gap is maintained by welded spacer studs although some designs do not require them.

Due to its inherent circular design and large surface area to volume ratio, the spiral heat exchanger offers unique advantages over other types of heat exchangers like the shell and tube.


High Thermal Efficiency
Single and long curving flow passages with a uniform rectangular cross-section ensure superior flow distribution, intense turbulence, and high heat transfer coefficients (50-100% greater than shell & tubes).

Self-Cleaning Passages
The spiral's single-flow passages induce high shear rates that scrub away deposits as they form. This self-cleaning effect reduces fouling and makes spiral heat exchangers ideal for handling tough fluids such as process slurries, sludge, and media with suspended solids or fibers.

Countercurrent or Co-current
Spiral heat exchangers normally operate in true countercurrent flow for close approaches and temperature crosses. Occasionally a co-current flow design has major benefits, especially in cooling or heating fluids prone to gelation, burn-on, freezing or similar skin temperature related fouling.

Small Footprint & Easy Access
The spiral heat exchanger is compact and requires minimal space for installation and servicing. Removable covers provide easy access to interior heat transfer surfaces for field inspections, routine maintenance, or manual cleaning if required.
