Hathernware FCR Full Chemical Resistance
A common difficulty in industrial drainage is the corrosion of pipe materials due to chemical attack. Whilst traditional vitrified clay systems offer high levels of resistance to many household chemicals, when we enter the industrial arena, both the level of likely attack and the consequences of failure get just that little bit higher.

The Hathernware FCR system has been developed over 50 years to provide the best solution for aggressive chemical discharges in industry.

With a proven resistance to over 90% of common industrial effluent products, many designers will find that, where discharges of aggressive chemicals is causing the most concern, Hathernware FCR offers a safe transport system from plant to treatment centre. FCR is based on a fully chemically resistant clay material first used in industrial process vessels so the drainage system can often cope with highly corrosive chemicals in process concentrations to cover many people's worst-case scenario.

Hathernware HT Thermal Shock + Full Chemical Resistance
By far the biggest single threat to ceramic pipes in the process industry is high temperature. Whilst traditional vitrified clay pipelines can withstand quite high constant temperatures, if the pipeline is regularly subjected to a rapid change in temperature from ambient to hot or vice-versa, then the ceramic body can quickly be destroyed by the phenomenon known as Thermal Shock.

Thermal shock occurs when the thermal expansion of a material overcomes the forces holding that material together. Traditional ceramics have a very high susceptibility to thermal shock.

The Naylor Hathernware HT pipe body however, has been further refined from our FCR material. The addition of certain compounds and very careful blending has enabled Naylor Hathernware to produce a pipe body of high structural strength (equal to traditional vitrified clay), very high chemical resistance (equal to FCR clay) and resistant to Thermal Shock at temperature changes of up to 120°c.

This makes Hathernware HT the only ceramic material suitable for use in areas subjected to intermittent discharges of high temperature effluents, such as Hospital Sterilisation suites, boiler blow down drains, laboratory, food processing and beverage production drainage systems.

Band-Seal Chemical Couplings
The Naylor Band-Seal Chemical Coupling range offers specifiers a modern corrosion resistant mechanical, flexible jointing system, which can be used with any plain-ended pipe system. The heat-shrinkable fluoropolymer lining offers extremely good chemical resistance whilst the EPDM or Nitrile rubber coupling body - selected on the basis of the prevalent ground conditions - and Austenitic Stainless Steel clamping bands, combine to provide a chemical coupling with excellent mechanical performance.
