Strong Acid Anodic Protection Acid Heat Exchanger Energy Saving Sulfuric Acid Cooler

Products Description
1.Descripition:
Anodically protection coolers are widely used in the production of sulfuric acid drying and absorption section. The function of anodically protection coolers is by applying anode current, so that the surface (stainless steel) which contact with sulfuric acid can be protected, then the annual rate of corrosion control in the range of 0.01-0.03mm.
Chemical equipment plant underneath TIANHUA has an occupation area of 6000m² with welding laboratory, inspecting room, material testing room, machine work room. For ensuring the quality of the product, the Anodically protected coolers are performed many processes as follows: firstly, the product is designed and manufactured referring to the Type I standard of pressure vessels and is tested in the ways of materials, evaluation for welding process, X radiographic inspection, etc. Secondly, welding quality of orifice of heat exchange tube is tested by ammonia leak test. Finally, hydrostatic pressure test is put up. Chemical equipment plant underneath TIANHUA has Manufacture License of Special Equipment of People’s Republic of China (class A2) and may be standard of ASME.
2.The working principle:
The working principle of the concentrated sulfuric acid equipments with anodic protection is as follows: whole equipment surface contacted with concentrated sulfuric acid is anode, one or more than one cathodes are installed, thus forming a current loop through sulfuric acid. To protect the equipments, an external anodic current is imposed, and anodic polarization occurs. The polarization potential is promptly passed via the induced passivation potential, and enters the stable passive region, then is maintained in this region. Thus, a passive film can be formed on the metal surface, which can make the corrosion rate of equipment decrease in concentrated sulfuric acid.
