Large Caliber Tube Furnace
The large-diameter tube furnace uses resistance wire as the heating element, adopts a segment program temperature control system, phase shift trigger, thyristor control, and the furnace chamber insulation material uses alumina ceramic fiber material, which has good heat resistance, fast heating rate, high efficiency, and energy saving. The furnace tube uses a high-purity quartz tube, which has good thermal conductivity, strong resistance to thermal shock, good insulation and high-frequency characteristics at high temperature, and resistance to chemical erosion. It is widely used for laboratories, industrial and mining enterprises, scientific research units for element analysis and determination, annealing of general small steel parts, brazing, and heating of new materials such as electronic ceramics.

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,...
