1. Among the factors affecting the quality of stainless steel electric heating pipes, the quality of materials accounts for important reasons.
2. Reasonable selection of raw materials for electric heating pipes is a prerequisite for ensuring the quality of electric heating pipes;
3, the selection principle of pipe: temperature and corrosion resistance;
4, the choice of resistance wire: Cr20Ni80;
5. Selection of magnesium oxide powder: industrial grade magnesium oxide powder;
6, the choice of sealing materials: silicone oil + 704 sealant.
The stainless steel electric heating tube is made of metal tube. This metal armored electric heating element can heat air, metal mold and various liquids.
The stainless steel electric heating tube is formed by placing an electric heating element in a metal tube and closely filling the void portion with crystalline magnesium oxide powder having good heat resistance, thermal conductivity and insulation, and is processed by other processes. The utility model has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life. Widely used in a variety of saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot stamping and other devices.
