Name: Zirconium Tube 
 Specifications: Φ8.0-89.0 (outside diameter) ╳ 1.0-10.0 (wall thickness) ╳ L (length) mm 
 Status: annealing 
 Key Features: tensile strength HB> 379Mpa thermal conductivity = 0.040Cal/cm2 (required shape can be bent) 
 Applications: tank coil, shell and tube heat exchangers, heat exchanger, evaporator, heater and artificial Cecil bayonet capsule shell and tube heat exchangers, tubular heat exchanger, heat pipe, tube preheat devices, chemical equipment such as reactor coil. 
 For example: In the vapor pressure 239000Pa, temperature 373K, prime tube body with 5% sulfuric acid, zinc sulfate 3%, 6% sodium conditions, the use of zirconium instead of lead plate coil, etc., the useful life of more than 10 years. 

 Produced according to user needs. 
 Zirconium plate heat exchanger: 
 Specifications; standard specification, power has 1.5KW-50KW, 
 Morphology; under heating power can be made of "L" type, "U" "0" type, etc, and with a thermal protection device. 
 Use; for titanium incompetence acid and alkali media (except hydrofluoric acid). 
 In polymer production, the application of zirconium in place of graphite heat exchangers. Although the cost of heat exchanger zirconium about 4 times higher than that of graphite, about 2 times higher than titanium, but it is durable enough to cover the cost of fees. 

 We have equipment in a variety of pesticides conducted studies of industrial applications of zirconium, such as pesticides reactor was carried out the practical application of zirconium and coupon tests. The conditions of pesticide hydrolysis: 20% sulfuric acid + a-naphthylamine; temperature 220-250 ℃; 15 atmospheres (1520kPa), a process time of 7h, in this condition serious equipment corrosion, 1mm thick ordinary steel, the reaction after Corrosion perforation. Original use of the tank lining 12 - 14mm thick layer of lead coating, is easy to pollute the environment, is also poor corrosion resistance of lead, a lead lining reactor, only approved material that is perforated with 50-60 leakage. Zirconium coupon test conditions are: the production of sulfuric acid + 20% medium A naphthylamine; production of 200-250 ℃; pressure 14-15 atm (1419 - 1520kPa). The results showed that the increase over time, zirconium base metal and weld metal oxygen content slightly increased, but more moderate rate, the mechanical properties of zirconium does not cause deterioration. The hydrogen content in this medium was gradually decreased the corrosion can reduce fragility, zirconium benefit, the annual corrosion rate was only 0.024-0.04mm / a.
