Stainless Steel Vacuum Annealing Furnace
This equipment is a horizontal structure with a square structure in the middle of a circle, which can ensure high vacuum efficiency while also making the furnace resistant to deformation and durable. The furnace is made of 310S stainless steel, which has good temperature resistance and strong pressure bearing capacity. The outer layer is carbon steel, and the two layers are cooled by circulating water, which has a long service life. It is mainly used for vacuum annealing of special materials, stainless steel, selenium steel sheet core, precious metal parts, silver-copper composite rivets and sheet parts.

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,...
