The challenge in maintaining reliable piping systems
Jorge Solorio explains how to avoid premature corrosion in piping systems used for mining engineering applications.
materials or leaching precious metals from the ground, the challenge to maintain long-term, reliable piping systems is significant. Extracting minerals of lower concentration from deep earth causes a shift in the chemistry of processed ores. Tis can result in internal and external corrosion, as well as sedimentation and crystallisation and ultimately, creating ongoing maintenance challenges and costly premature failures.

The solution Unlike traditional metallic pipes, Corzan industrial piping systems are made from a non-corrosive, durable chlorinated polyvinyl chloride (CPVC) technology that makes them chemically inert to most mineral acids, bases and salts, and aliphatic hydrocarbons found in mining applications, as well as chemical processing, water systems, and wastewater treatment facilities. Corzan piping systems, constructed from a speciality high-performance material, provide excellent hydraulic
capabilities that ensure optimal flow rates and lower installation costs. Corzan industrial piping systems eliminate internal and external corrosion caused by liquids and vapours commonly found in industrial environments. Te benefits of using Corzan CPVC piping systems are as follows:
l Meets ASTM F441 material classification 4120-06, with a pressure rating 25% higher
than standard CPVC at 180˚F (82˚C) l Drop impact strength up to three times standard
CPVC piping material l Highest heat deflection temperature (HDT) of any CPVC
piping compound l Fitting material that has improved creep resistance and ability to withstand long-term, high-temperature

Corzan pipe can be easily cut with a ratchet cutter, wheel- type plastic tubing cutter, power saw, or fine-toothed saw. Burrs and filings must be removed from the outside and the inside of the pipe.
