Hathernware "Thermachem" Drainage
The key benefits of the Hathernware ceramic are its thermal shock resistant properties and its resistance to aggressive chemicals.
"Thermachem" is the name given to the Hathernware drainage system whose piping provides a wide range of industries with robust drainage systems with an extensive lifespan and with both cost and installation benefits.
The "Thermachem" range of pipes and fittings have been developed to handle extremes of temperature variation that would normally result in cracking of convential clay pipes due to thermal shock and to handle the most aggressive of chemicals. Situations that are commonly found in the Process Industry.
Selecting a material with a high level of thermal shock resistance coupled with resistance to aggressive chemicals at the outset gives the plant manager and owner the flexibility to introduce new processes or process conditions at a later stage of the plant's lifetim and to change the cleaning regime or effluent composition.
A correctly specified "Thermachem" system will give many years of trouble free service and can be directly coupled to other Naylor drainage systems.
Pipes and Fittings
The standard range of pipes and fittings are shown in the attached download but specials can be made to solve most drainage problems.
Trenchless Installation
A range of pipes has been developed for trenchless installation. This allows pipelines to be installed in heavily trafficked areas or under floor slabs without surface disruption. The pipes also accommodate applications that require high temperature variations in the discharges as well as any chemical discharged resulting from process or cleaning operations.
Couplings
Connections are made using purpose made adaptors or by the use of the Naylor Band-Seal coupling system.
"Thermachem" Sleeve Couplings
Manufactured in high impact polypropylen with elastomeric seals providing watertight, flexible mechanical joint assemblies, complying with BS EN295-1: System G. Coloured yellow for easy identification on site. Suitable for sudden changes in temperature and some chemical effluents.
Band-Seal Chemical Couplings
Manufactured in high grade EPDM or Nitrile elastomers conforming to EN681-1 with corrosion resistant austenitic stainless steel clamping bands and fluoropolymer liner. Suitable for sudden changes in temperature and most chemical effluents.
Joint Performance and Flexibility
Joint assemblies meet all the requirements of BS EN295-1. They accept angular deflection and shear resistance without leakage, when tested under an internal or external water pressure of 50kPa (5 metres head).
The design of both ther "Thermachem" and Band-Seal Chemical Couplings ensures that pipelines will accommodate minor settlement and ground movement without failure.
Technical Services
An in-house advisory service is able to help with problem-solving on most aspects of drainage and plant design.
For drainage projects, Naylor prefers to be involved at the very early planning stage, working with the consulting engineers, chemical engineer designers, works plant managers etc, to identify the effluent composition, concentration and temperature at each release point. The full range of Naylor pipe systems can accommodate virtually all applications and conditions from domestic to the most aggressive of trade effluent at temperture well above ambient. Because of this, Naylor is well qualified to advise on the specification of the most appropriate type of pipe and coupling, thus avoiding unnecessarily onerous specifications and costs.

Typical Applications for "Thermachem" Drainage
Where hot and/or corrosive liquids are discharged:
- The chemical and process industries
- Pharmaceutical and research laboratories
Where sterile conditions involve the use of aggressive cleaning fluids and/or supersteam:
- Food processing plants
- Breweries
- Dairies
- Hospital sterilisation areas
In other aggressive environments:
- Badly contaminated ground
- Areas susceptible to chemical spillage
Quality Standards
Hathernware "Thermachem" drainage complies with the stringent requirements of BW EN295-1 and BS65:1991, extra chemical resistance.
Naylor Hathernware is manufactured in accordance with BS EN ISO9002.
