How to Find the Right Industrial Pipe Material for Chlor Alkali Plants

 

Industrial-grade chlor-alkali production has been underway for more than 120 years, and in many ways, the principles by which these plants operate have not changed significantly. What has changed is the range of material choices available for chlor-alkali systems.

Today, chlor-alkali plants operating across the globe require pipes, tanks, headers, manifolds, storage towers and more to be fabricated with resilient materials that can stand up to some of the harshest conditions existing in any industry.

Delta Air Lines Trusts Corzan CPVC to Prevent Corrosion

 

At Delta Air Lines' Atlanta-based Technical Operations facility, the landing gear of its entire fleet is taken apart, cleaned, metal-plated, and put back together again.

A polyvinyl chloride (PVC) system was servicing the ventilation needs in the facilities plating shop, operating under highly aggressive chemicals, very high temperatures, and corrosive conditions. When the system began to fail, Delta knew it had to be replaced by a stronger, more chemically resistant material that could withstand the facility’s corrosive environment.

The engineers found the solution to their problem in Corzan chlorinated polyvinyl chloride (CPVC).

Why the Experts Trust Corzan CPVC Sheet for Critical Applications in the Chemical Industry



Handling, storage and processing of corrosive or abrasive liquds and gases is a day-to-day challenge for the chemical processing industry.

Engineers are confronted with a wide choice of materials of construction, including:

  • Stand alone thermoplastic
  • Glass fibre reinforced plastic (FRP)
  • Dual laminate constructions with thermoplastics (PVC, CPVC, PE, PP) and/or fluropolymer liners (ECTFE, PVDF, FEP, PFA)

Dual laminate technology offers greater safety making it one of the preferred solutions for demanding chemical applications. This is thanks to the combination of superior chemical resistance of thermoplastics with the mechanical strength of FRP.

Thermoplastic Piping Systems and Mitigating Corrosion



 

Webinar: The Trend Toward Thermoplastic Piping Systems for Mitigating Corrosion

Duration: 60 Minutes

View On Demand

Power Plants create some of the greatest demands for piping systems. The chemicals used in water treatment are not only highly corrosive, but they are also often conveyed at elevated temperatures, subjecting metallic systems to corrosion, process leaks and premature failures that jeopardize plant efficiency, as well as safety and environmental compliance. Even the more expensive alloys, as well as lined carbon steel, are challenged to provide a cost-effective, reliable solution.

Webinar Summary:

Chemical processing plants create some of the greatest demands for piping systems. The chemicals used are not only highly corrosive, but they are also typically conveyed at high temperatures, subjecting metallic systems to corrosion, process leaks and premature failures that jeopardize plant efficiency, as well as safety and environmental compliance. Even the more expensive alloys, as well as lined carbon steel and such non-metallic alternatives as HDPE and FRP, are challenged to provide a cost-effective, reliable solution.

Thorpe Plant Services Turns to +GF+ Corzan CPVC Industrial Piping Systems to Meet Customer Demands for Reliable Handling of Hydrochloric AcidSample



Insights from an industry leader

By Bryan Hutton, Corzan® Industrial Piping Systems, part of The Lubrizol Corporation

Chlor-alkali plants create some of the most corrosive environments imaginable. The transport of harsh chemicals at extreme temperatures in combination with the high voltage electrolysis process can quickly compromise the integrity of most piping systems. So when one of the largest producers of chlor-alkali products in the world needed a proven-effective solution for transporting and storing its hydrochloric acid, it turned to Thorpe Plant Services in Houston which turned to Corzan® Industrial Systems from The Lubrizol Corporation.
