A leading steel manufacturer in the US selected Durcor® for their piping system to safely manage and transfer hydrochloric acid (HCl) within their tank farm and pickle line waste streams. Since HCl is a highly corrosive chemical, it was critical that the selected piping system would be constructed of the most corrosion resistant materials, have the highest reliability and safety, and have the
lowest total cost of ownership.

After carefully reviewing the Durcor® technology, they determined that the Durcor® fluoropolymer lined composite piping system, manufactured by Andronaco Industries, met the requirements of corrosion resistance, reliability, safety, and lowest total cost of ownership.

At 8 years post installation, the Durcor® piping system had provided this steel manufacturer with a return on their investment by meeting and exceeding expectations of performance and extremely low maintenance costs. In fact, the steel manufacturer confirmed that only one fitting required any maintenance since the piping system
was installed.

Below are illustrations displaying how the Durcor® piping system has provided significant returns on investment for this leading steel manufacturer. Other steel manufacturers as well as manufacturers of other highly corrosive fluids (e.g., chlor-alkali, peracetic acid, etc.) have seen similar results. Durcor® has consistently exceeded performance expectations while retaining extraordinarily low maintenance costs.

Eight years after installing the Durcor® fluoropolymer lined composite piping system to safely manage and transfer hydrochloric acid within a steel mill tank farm and pickle line waste streams, the steel manufacturer confirmed that only one fitting required any maintenance since installation.

When comparing the total cost of ownership of the Durcor® PTFE/FEP lined structural composite piping system to PTFE/FEP lined alloy piping systems, there are several additional cost saving advantages of the Durcor® piping system including:

• The Durcor® piping system can achieve a weight reduction of up to 75% as compared to lined steel 
  
  • Reduction in transportation costs
  • Reduction in installation costs -less labor/rigging,
    minimal crane requirements
• The Durcor® piping system is 100% corrosion resistant
  
  • Zero corrosion impact internally from permeated chemicals
  • Zero corrosion impact externally from atmospheric conditions
  • Zero corrosion impact from pipe being insulated
• The Durcor® piping system is maintenance free
  
  • No exterior painting required for corrosion resistance, no corrosion under flanges
  • Durcor® piping can be stored for years with no effect on product integrity or performance
  • UV inhibitor incorporated in external pipe to extend life in outdoor installations
• The Durcor® piping system can be pigmented at the time of manufacturing for color coding piping systems related to distinguishing content of fluid transfer lines
• Durcor® pipe is self-insulating
  • Durcor® pipe housing composite construction has been tested not to exceed 180°F if the process fluid is 300°F (maximum operating temperature of Durcor®)
  • If the piping system is being insulated for burn protection, insulation may not be necessary with Durcor® pipe
  • When insulating piping for thermal loss, if Durcor® piping is used, no insulation or less insulation will be required as compared to lined steel Durcor® Comprehensive Piping System Hydrochloric Acid Service, Steel Industry
