What is FlowGuard CPVC Pipework?

  • FlowGuard® CPVC pipework, known for its durability and chemical resistance, has been a staple in plumbing for over 60 years, ideal for residential, commercial, and industrial systems. 

  • FlowGuard® CPVC pipe and fittings guarantee safe, clean water quality,  approved for all potable water systems and resisting biofilm formation better than many other materials. 

  • FlowGuard® CPVC stands out for its fire resistance, robust joint integrity, and consistency as a top-performing polymer piping solution worldwide. 

FlowGuard CPVC pipework (chlorinated polyvinyl chloride) has truly stood the test of time as a durable and robust material, extensively utilised in plumbing applications globally for over half a century.

Developed by Lubrizol Advanced Materials, FlowGuard CPVC’s intrinsic chemical resistance, dependability, and capacity to withstand high temperatures and pressures position it as a top choice for residential, commercial, and industrial piping and fire sprinkler systems.

FlowGuard CPVC plumbing systems, now exceeding six decades in service, continue to be a source of clean and safe water for families worldwide.

Exploring the Advantages of FlowGuard CPVC Pipework for Residential Plumbing Systems

Let's dive into the reasons why FlowGuard CPVC pipe and fittings are trusted in homes across the globe:

Superior Water Quality:

Distinguished international organisations such as NSF International meticulously assess and endorse materials for use in potable water systems. These certifications serve as a guarantee that FlowGuard CPVC pipework does not introduce harmful substances into the conveyed water. FlowGuard CPVC, for instance, holds approvals for all potable water pipe systems, featuring compounds free from plasticizers, flame retardants, bio-stabilizers, or anti-static agents.

Robust Joint Integrity:

FlowGuard CPVC pipe and fittings are interconnected using solvent cement, a substance that bonds the pipe and fitting at a molecular level. Unlike adhesives utilised in alternative piping systems, these solvent-cemented joints emerge as the sturdiest segments of the pipework, resistant to separation when properly installed.

Resilience to Chlorine:

While chlorine-based disinfectants, notably chlorine dioxide, present a risk of pipe failures in PPR (green pipe), PEX, and metallic pipes, FlowGuard CPVC remains impervious to chlorine effects, thanks to its physical properties that ensure water safety, thus averting potential pipe mishaps.

Combating Biofilm Formation:

Water distribution systems are breeding grounds for bacterial growth, yet FlowGuard CPVC plays a pivotal role in maintaining water purity. Numerous international studies bear witness to FlowGuard CPVC’s consistent superiority over copper and other plastic piping materials, particularly PPR, in effectively thwarting biofilm formation.

Fire Endurance

FlowGuard CPVC showcases fire resistance capabilities and does not fuel combustion, standing in stark contrast to certain plastics that ignite and sustain burning post-fire source removal. FlowGuard CPVC, boasting the prime fire classification for a non-metal product, attributes this feat to its minimal flame and smoke generation characteristics.

Not All CPVC Pipework Is Created Equal

It is paramount to understand the differences between CPVC variants. Instances where CPVC systems exhibit degradation over time often trace back to inadequate material quality or improper installation techniques. As an industry leader and pioneer in CPVC technology, FlowGuard Pipes and Fittings stand as the premier and high-performing polymer piping solutions on the market.
