Spiral pipe PALADEX®

for waterpolyethylene (PE)

Obsolete sewer systems, inadequate for the growing urban population, increasingly intense rainfall, and frequent hydrogeological instability require the development of innovative solutions for the disposal of larger quantities of rainwater and sewage. This involves installing pipes capable of adequately responding to all the internal and external stresses to which the drainage system is subjected. The innovative idea behind this production consists in combining the typical characteristics of polyethylene – abrasion resistance, light weight, minimal roughness, inertia to chemicals, versatility and ease of installation – with the characteristics of steel, which has an elastic modulus 200 times higher than polyethylene. The PALADEX® pipe is made using a continuous helical winding process of polyethylene and steel, appropriately shaped with an omega-shaped profile. The combination of the two materials, along with the choice of an omega-shaped profile, gives the PALADEX® pipe characteristics and performance that are significantly superior to pipes made of thermoplastic material and other pipes on the market for the same intended use (fiberglass, concrete, cast iron, stoneware, etc.). Furthermore, the particular and innovative structure gives the PALADEX ® tube , with the same annular rigidity, a lower weight than tubes with the same intended uses on the market. The average weight of a PALADEX ® DN/DI 1200 SN8 spiral pipe , in fact, is equal to 70 kg/m, that of a classic spiral polyethylene pipe is equal to 120 kg/m and that of a reinforced concrete pipe is greater than 1900 kg/m.
