Product Description

High Purity MgO Insulation Tube Used for heating two-terminal electric ceramic heating element 

Product Description

 

1. Introduction

MgO tube as heating element good resistance and thermal shock MgO tube, high density owing to its excellent heat resistance and electric insulation properties.
They are widely used in the defense industry, refractories, heat-resistance, insulation resistance instruments, electrical equipment, armored thermocouple. Armored heaters etc magnesia tube used in heating element single hole Mgo oxide tube used for tubes with double-sides, used for heating two terminal electric heating element.

The products of single end electric heating tubes have the advantages of insulation, pressure resistance and good heat conduction, and have been used by major cartridge heater,thermocouples &sensors,hot runner heater and electric heating tube manufacturers. The product is fired in the tunnel pusher cellar furnace, with high density (2.3g/ml).
