Principle

High Pressure Tube Furnace operates under a controlled atmosphere or high vacuum conditions. It utilizes a high-temperature nickel-based super alloy furnace tube that withstands both high temperatures and pressures. The furnace's working temperature reaches up to 1100°C, while its working pressure can reach 15 Mpa at ambient temperature and 4 Mpa at 800°C. The furnace tube flange seal employs a solid copper O-ring, adapting to both negative and positive pressures for extended service life.

Warnings

Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
