(Coestilen®) is the drainage system for welding made of polyethylene which is exceptionally elastic and resistant to mechanical stress and vibrations. The program consists of pipes and fittings in diam. of 32 to 315 mm and includes a wide range of joint fittings and connections to sanitary and sewage systems. The high molecular weight of PE is a guarantee against fracture due to prolonged use. It is also particularly suited to absorb mechanical stresses of significant intensity; specifically for installation in seismic areas. Moreover it offers excellent resistance to operating temperatures between –40° and +70°C, with the capacity to handle peaks of up to 95°C. Coestilen® pipes and fittings are compliant with UNI EN 1519 operation the treated water is disinfected by dosing hypochlorite with the help of dosage pump
OUTSTANDING ELASTICITY AND RESISTANCE TO MECHANICAL STRESS AND VIBRATIONS.
IDEAL FOR SEISMIC AREA AS OUTSTANDING RESISTANCE TO WORKING TEMPERATURES BETWEEN –40° AND + 70°C,TO CHEMICALS AND THE EF FFECTS OF THE WEATHER RESISTANCE TO PRESSURE AND ACCIDENT PRESSURE SURGE.
