What kind of electric heating tube is better? This is a question that our customers often ask. This is also a question that cannot be answered directly. We know that the materials of the electric heating tube are mainly divided into: stainless steel 201, stainless steel 304, stainless steel 321, stainless steel 310s, stainless steel 316, and Inglelite materials. Each material has its own characteristics, so only by choosing the right material can it be regarded as a good electric heating tube material.
The material of the electric heating tube is mainly selected according to the following aspects:
One, working temperature
The working temperature is about 200-300 degrees, and the material is stainless steel 304.
The working temperature is about 400-500 degrees, and the material of stainless steel 321 is used.
The working temperature is around 600-700 degrees, using stainless steel 310S material.
The working temperature is about 800-900 degrees, and the material is made of Ingle.
Heating pipe
2. Heating medium
Tap water: made of stainless steel 304;
Oil: Stainless steel 304 material or iron material.
Three, whether corrosive
Heating weak acid and weak alkaline liquid: made of corrosion-resistant stainless steel 316L.
Heating strong acid and strong alkaline liquid: Refer to the selection table of liquid electric heater (stainless steel 316 + electrostatic anti-corrosion coating, generally any acid and alkaline liquid can withstand, the power per meter is generally set to about 2KW, slightly larger Can.)
Through the above understanding, we know that only a suitable electric heating tube material can be regarded as a better electric heating tube material.
