Stainless steel 316L liquid heating tube

It is made of stainless steel 3 as the shell, and spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) are evenly distributed along the central axis of the tube. The gaps are filled and compacted with crystalline magnesia sand with good insulation and thermal conductivity. Both ends of the tube mouth are sealed with silicone. Heating elements processed by other processes. The anti-corrosion ability of stainless steel 3 liquid heating tube is stronger than that of stainless steel 3. Precautions for use:
Stainless steel 3 liquid heating tube is allowed to work under the following conditions
. The relative humidity of the air is not greater than 100%, and there are no explosive and corrosive gases.
B. The working voltage should not be greater than .times of the rated value, and the shell should be effectively grounded.
Insulation resistance, dielectric strength:/
Stainless steel 3 liquid heating tubes should be positioned and fixed. The effective heating area must be completely immersed in liquid or metal solids. It is strictly prohibited to burn in the air. When scale or carbon is found on the surface of the pipe, it should be cleaned in time before use to avoid affecting heat dissipation and shortening the service life.
When heating fusible metals or solid nitrates, alkali, bitumen, paraffin, etc., the voltage should be lowered first, and then the voltage can be raised to the rated voltage after the medium is melted.
When heating air, the elements should be arranged evenly across each other so that the elements have good heat dissipation conditions and the air flowing through can be fully heated.
When heating nitrate salt, safety measures should be taken into consideration to prevent explosion accidents.
The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media and moisture. The lead wire should be able to withstand the temperature and heating load of the wiring part for a long time. Excessive force should be avoided when tightening the wiring screws.
Stainless steel 3 liquid heating tubes should be stored in a dry place. If the insulation resistance is lower than that due to long-term storage, it can be dried in an oven at about ℃, or the voltage can be reduced and heated until the insulation resistance is restored.
The magnesium oxide powder at the outlet end of the stainless steel 3 liquid heating tube prevents pollutants and moisture from infiltrating in the use place, and prevents leakage accidents.
