Product Introduction
Description
Titanium ,no harmful effect to us,has the super strong corrosion resistant ability. Our titanium heat exchanger use seamless pure titanium tube as heat conductor, can ensure the titanium heat exchanger can be used for a long time, without any cost in the after-sale services.

Comparison Table
Items | Titanium straight tube | Titanium Corrugated tube |
heat exchange area | 1：1 | The proportion of titanium straight tube and titanium corrugated pipe is 1.3:1. After rolling into 1 meter titanium corrugated tubing,it need 1.3 meter titanium straight tube (The ratio has a direct relationship with the depth and the quantity of thread) |
Water flow rate | Small resistance and fast speed | Its heat transfer time is long, because the big resistance and slow velocity when the medium through the intermal thread channel. |
Turbulent reactive | Molecular activity in general when kick through the smooth surface, | the molecules activity will be increased which turbulent in the wake of screw channel. |
Cleanse filth | ordinary | Turbulence form rotating flushing, which increased cleaning filth ability |
The structure, size, welding head | standard | It can swaps without preconditions with titanium straight tube, but it needs smaller volume, because of the high efficiency. |
The total thermal efficiency | standard | It is 1.3-2.6 times for titanium straight tube. (The factors has a direct relationship with the depth and the quantity of corrugated) |
titanium twist tube for Heat exchanger size:
1) Pure seamless titanium tube,gr1 grade,common size
19.05 mm OD x /0.7/0.9/ 1.2/ mm WT Titanium tube |
25.4 mm OD x 0.7/0.9/1.2/1.6 mm WT titanium tube |
31.75 mmOD x 0.9/1.2/1.6 mm WT titanium tube |
38.1 mmOD x 1.2/1.6/2 mmWT titanium tube |
we also can accept customzied dimension as your requirement.
2) The titanium coil pressure loading capacity was designed base R410a high pressure work condition, The max. working pressure is 52 bar. and the extreme pressure was 360bar in our test.
3) 100,000 times alternating pressure (Low pressure 0 bar, high pressure 52bar) test shows it can be used more than 20 years. Never corrosion.
Advantage of titanium twist pipe
1. High heat transferefficiency. In the same diameter,wall thickness and the lengthof the titanium corrugated tube. The thermal efficiency is 1.3-2.6 times to the titanium straight tube.
2. Strong corrosion resistance. The heat transfer tube-Gr1 titanium corrugated tube, made according to standard GB/T3625-1995, There are 4 times 43 bar high pressure test and precise halogen leaking test in the Production. And 100000times 4.5bar fatigue test to make sure no leakage.
3. Descaling ability. 4 head titanium corrugated tube is without welds. It can greatly reduce the leakage. It also can be turbulent flowing, which reduce the rate of scale formation. So as to prolong service life, reduce maintenance costs.
4. Good quality Shell. High quality PVC, acidproof, alkaliproof, anticorrosion, good resistance to pressure, RoHS conformance, environmentally.
5. Beautiful appearance, strong strain compensation ability, characteristics of compact structure, small and light. It is convenient installation. Titanium twisted tube heat exchanger will be the mainstream of the industry. It is the best choice.
