HT Sleeve Pipes & Fittings

DN100, 150, 225 and 300 plain-end specially formulated clay pipes and fittings with Band-Seal Chemical Coupling joints. Where less aggressive discharges are expected, the Naylor HT sleeve coupling can be utilised instead of chemical couplings leading to a more cost-effective system.

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.
