Liquid heating tube is mainly "metal tubular electric heating element. The outer tube of liquid heating tube is made of nickel-chromium iron material, which has the advantages of high mechanical strength, heat resistance, corrosion resistance and not easy to scale. The different expansion coefficient of the outer tube and the microseismic can be used to remove the scale. The fatal defect of easy scaling of stainless steel and copper heating elements is solved.
Liquid heating pipe flange construction/liquid heating pipe
The flange structure of liquid heating pipe is round, square and bolt shape respectively. Square, bolt - shaped structure exquisite, occupy a small space, easy to arrange. Users can choose according to different requirements.
Liquid heating tube technical specifications/liquid heating tube
1. Power deviation: +5~ -10%
2. Cold insulation resistance: ≥50M ω
3. Insulation voltage strength: 200V working voltage 1500V/1min 380V working voltage 2000V/1min
Liquid heating tube Instructions/liquid heating tube
1. The operating voltage shall not be greater than 1.1 times of the rated value, and the enclosure shall be effectively grounded.
2. All effective heating dimensions must be immersed in water to avoid empty burning.
3. Pipe surface scale should be removed regularly, so as not to affect heat dissipation and shorten the service life.
4. The components should be stored in a dry place. If the insulation resistance is lower than 1M ω for a long time, the voltage can be lowered to heat or dry in the oven until the insulation voltage is restored.
5. Do not tighten the wiring screws too hard
