Bright Vacuum Annealing Furnace
This tube furnace uses resistance wire as heating element, phase shift trigger, thyristor control, furnace chamber uses alumina polycrystalline fiber material, furnace tube uses high-purity quartz tube, both ends are sealed with stainless steel flanges, flanges are supported by stainless steel brackets, double-layer furnace shell is equipped with air cooling system, can quickly rise and fall temperature. This furnace has the advantages of a balanced temperature field, low surface temperature, fast temperature rise and fall rate, energy saving, etc. It is suitable for colleges and universities, scientific research institutes, industrial and mining enterprises to do high-temperature atmosphere sintering, atmosphere reduction, CVD experiments, vacuum annealing, etc.

Why Hot Oil Tracing Still Earns Its Place in Process Plants A refinery must keep a sulfur transfer line above its melting point along a 400-meter pipe rack where no steam supply exists. A chemical plant must hold a polymer line at a stable 200°C through winter. In both cases, hot oil tracing delivers uniform, controllable heat without the condensate handling of steam or the electrical load of resistance tracing. Consider hot oil tracing when a site already operates a thermal oil heating system,...
