What kind of electric heating tube is durable and good? This is a question we receive frequently asked by customers. This is a question that cannot be answered directly. We know that the materials of electric heating pipes are mainly divided into: stainless steel 201, stainless steel 304, stainless steel 321, stainless steel 310s, stainless steel 316L, Inglelite material 840, 800, 825, 601, 600, etc. . 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:
1. Working temperature
Working temperature is about 200-300 degrees, using stainless steel 304 material
Working temperature is around 400-500 degrees, using stainless steel 321 material
Working temperature is around 600-700 degrees, using stainless steel 310S material
The working temperature is around 800-900 degrees, and the material is made of Ingle
2. Heating medium
Tap water: made of stainless steel 304;
Food-grade 316L material is used for heating drinking water, which is a scale-proof coating for water that is more prone to scale formation
Oil: Stainless steel 304 material or iron material.
3. Whether it is corrosive
Heating weak acid and weak alkaline liquids: use corrosion-resistant stainless steel 316L material.
Heating strong acid and strong alkaline liquids: Refer to the selection table of liquid electric heaters (stainless steel 316 + electrostatic anti-corrosion coating, generally any acid and alkaline liquids 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.
