The metal sheath is structurally divided into two categories: seamless pipes and welded pipes!
The cartridge heater is introduced through the previous "electric cartridge heater structure". It is known that the metal sheath is an important part of the cartridge heater. Since the shell of the electric cartridge heater is in direct contact with the liquid or air, it is required to be selected by the cartridge heater. The specific requirements of the cartridge heater are as follows:
● The metal sheath used in electric cartridge heater is structurally divided into two types: seamless pipes and welded pipes. There are carbon steel, copper, and stainless steel in terms of materials.
● The requirements for the metal sheath are:
● For seamless thin-walled pipes, uniform wall thickness is required; for welded pipes, no convex bumps are required at the welds on the inner wall of the pipe;
● No trachoma holes
● Uniform performance of all parts of the pipe
● Common specifications are Φ8 * 0.6, Φ10 * 0.8, Φ12 * 1.0, Φ14 * 1.0, Φ18.5 * 1.0, Φ21 * 1.0, Φ23 * 1.5, Φ25 * 1.5
