Durcor Comprehensive Piping System

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.

Present day 2024, and 8 years later, the Durcor®
piping system has 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.

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 is approximately 1/4 the weight of a lined alloy piping system
  
  • 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

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 confi rmed that only one fitting required any maintenance since installation.
