Silicon nitride tube

Main features:
High temperature strength and thermal shock resistance:  Our silicon nitride tubes can withstand the harsh conditions of high temperature heating elements and aluminum, with a typical lifespan of over one year.
Minimal Reaction with Aluminum: Silicon nitride ceramic material minimally reacts with aluminum, helping to maintain the purity of heated aluminum, which is critical for high-quality processing.
Energy efficiency: Compared with the traditional upward radiation heating method, SG-28 silicon nitride protection tube can improve energy efficiency by 30%-50% and reduce overheating oxidation of aluminum surfaces by 90%.

Instructions for use:
Preheating treatment: To ensure safety, the product should be preheated to above 400°C to remove residual moisture before use.
Slow heating: When using the electric heater for the first time, it should be heated slowly according to the heating curve to prevent thermal shock.
Regular maintenance: It is recommended to clean and maintain the product surface every 7-10 days to extend its service life.

Our silicon nitride ceramic protection tubes are ideal for increasing the performance and service life of aluminum machined electric heaters due to their exceptional durability, energy efficiency and easy maintenance.
