There are several common types of heating tubes: stainless steel heating tubes, quartz heating tubes, ceramic heating tubes, copper heating tubes, iron heating tubes, titanium, PTFE, imported 800/840 heating tubes, etc.

Copper heating tube: The material is soft and easy to be drawn, and it is resistant to acid but not alkali. Because most of our domestic water is alkaline water (the coastal areas are more alkaline), it is easy to produce patina, poor corrosion, and the heating tube is easy to be hit by high temperature. wear, resulting in leakage. The pressure bearing capacity of the inner tank is prone to burst tube phenomenon at low and high temperature.

Quartz heating tube: It generates heat through a resistive film, and the thermal efficiency is within 90%. The advantages are safe and cheap. Disadvantages: 1. Fast thermal decay and short life. 2, low pressure, easy to break. 3. Slow thermal response.

What are the types of heating tubes for thick film heaters? What are the characteristics?

Stainless steel thick film heating tube:

1. Thermal efficiency: The stainless steel thick-film heating tube has the advantages of natural barrel-shaped water channels, and the heating is more uniform and efficient, the substrate is more pressure-bearing, and it is more compact and changeable, and its thermal efficiency is as high as 98% or more. Known as "the most ideal instant heat pipe" in the industry, its standing specifications are: 2200W, 3000W, 4000W, 5000W, etc.

2. Safety: The stainless steel thick film heating tube adopts the method of high temperature sintering up to five layers of insulation, and by virtue of its natural pipeline advantages, the separation of water and electricity is completely realized. hot water.

3. Material: The stainless steel thick film heating tube is made of SUS430 material. The stainless steel material has high hardness, is not easy to deform and is resistant to alkali (very suitable for domestic water heating), high thermal conductivity, small heat loss, uniform heating, and good thermal expansion and contraction. The core-wing stainless steel thick film heating tube directly prints and sinters the insulating film and the heating resistance film on the stainless steel tube by screen printing and sintering. Works fine.
