Quality of joint depends on the following instructions which have be followed carefully.

HANDLING OF PIPES & FITTINGS

When fusing, temperature of pipes & fittings have to be similar to ambient temperature measured by machine’s probe.

Therefore they cannot be exposed to strong wind or direct sunlight : their temperature may vary consistently from ambient temperature, affecting negatively fusion (pipe & fittings insufficient or excessive fusion). In case of high temperature, keep pipe & fittings away from direct sunlight and wait until their temperature is similar to ambient temperature.

PREPARATION

Cut pipe’s edges straight, using special pipe cutters. Carefully try to eliminate pipe’s and fittings bends or ovalizations.

CLEANING

Carefully scrape oxidized layers on pipe’s or fitting’s edges with special pipe scrapers. Make sure scraping is uniform and complete over surfaces to be fused exceeding the middle of the fitting of about 1 cm; lack of this type of operation causes a superficial fusion only, since it prevents molecular interpenetration of parts and affects fusion’s result. Scraping methods like sand paper, emery wheel must be avoided.

Take out coupler from its protecting packaging, clean the interior according to manufacturer’s instructions.

POSITIONING

Insert pipe’s edges into the coupler.

It is necessary to use an aligner for:

- making sure parts are steady during fusion and cooling phase;

- avoid any sort of mechanical stress on the joint during fusion cycle and cooling;

FUSION

Fusion area should be protected from strong weather conditions , such as humidity, temperatures lower that -10°C or over +40°C, strong wind, direct sunlight.

Pipes & fittings used have to be of the same material or compatible material. Compatibility between materials have to be guaranteed by manufactured.

COOLING

Cooling time depends on diameter of coupler and ambient temperature. It is important to follow times given by manufacturer of couplers used.

To avoid mechanical stress on the joint (bending, tractions, twisting) disconnect cables and aligners only when joint has completely cooled down.
