By the fusion pipe and fitting the plastic melts to a homogeneous material unit.

Pipe and fitting are heated quickly with specially provided welding tools and joined together - finished!

Double material thickness at the joint - giving double safety at the otherwide critical point of a pipe system.

A permanent leakproof connection is created with the aquatherm fusion technique.

Handling

Transport and storage

firestop-pipes can be stored in all outside temperatures. Pipes should be stored and transported flat and fully supported along their length. Bending pressures are to be avoided. High impact should be avoided at extremely low temperatures.

Although firestop-pipes are extremely robust, it is recommended to treat the material always with care.

UV resistance

Pipes from fusiolen PP-R (80) FS should not be installed (without protection) where subject to UV-radiation. All firestop-pipes and fittings are supplied in UV-protected packaging to bridge transport and assembly time. Ultraviolet rays have an influence on all high polymeric plastics. Hence, pipes should not be stored unprotected outside for a long time. The maximum storage time is (outside) 6 months.

Fire bulkheading

All fire prevention systems which can prove equivalent licensing are suited for the firestop pipe system. aquatherm recommends equivalent the Rockwool Conlit fire retardant seals as an ideal fire prevention solution for the fire-stop-pipe system.

Procedures for additional repair

Cut out damaged / leaking section and replace as for a new installation or repair with pipe repair stick.

Chemical Resistance

On account of the special material qualities firestop-pipes and fittings provide extensive chemical resistance. firestop-transition connections and elements with brass inserts are not suitable for all media. The compatibility should be asked at aquatherm with media deviating from water. Please, use the "Enquiry for the chemical resistance" in the appendix.

Pipe friction loss

The pressure loss caused by friction is to be calculated hydraulically with the Hazen-Williams-formula.

The value to be used for C is 150, applicable for calculations of sprinkler installations and water supply.

General rules for the use of plastic pipes as sprinkler lines (according to LPCB)

In connection with the use of aquatherm firestop, the following is to be observed. The "scope of use" of plastic pipe shall be agreed between the plastic suppliers, purchaser/installer, authority having jurisdiction, and/or insureer in accordance with document supplier "Installation Instructions" but subject to the following criteria taking percedence.

» Use of plastic pipe and fittings is subject to water authority agreement for the territory concerned.

» LPCB approved quick response sprinklers shall be used with exposed (i.e. fire exposure) plastic pipe and fittings.

» Plastic pipe and fittings are suitable for use only with wet pipe systems.

» Use of additives is only permitted in accordance with the manufacturers installation instructions.

» Care should be exercised to ensure that joints are adequately cured, in accordance with the manufacturer's installation instructions, prior to pressurisation.

» Plastic pipe and fittings shall not be installed outdoors.

» Not suitable for drinking water.

» Where plastic pipe and fittings are exposed (i.e. fire exposure), the system shall be installed close to a flat ceiling construction.

» Sprinkler systems which employ plastic pipe and fittings shall be designed where possible to ensure there are no 'no flow' sections of pipework in the event of sprinkler operation.

» The system of pipes must be installed in accordance with the aquatherm installation instructions, which include the LPCB conditions of use agreed with aquatherm.

» The maximum normal ambient temperature of use shall not exceed 70° C.
» The products shall only be installed by LPCB certificated or registered installing companies (see Part 5, Section 1A and 1B above) or by firms outside the UK who can provide evidence of personnel training in the installation of the product. It is recommended that firms engaged in the installation of this product are also be certificated to ISO 9000.
