Descrição porminorizada da marca:Light and flexible. Lifetime under 50 year. Not are liable to corrosion and îòëî
salts æåíèþ. Carrying capacity in 1, 3 times more in contrast with
steel pipes. Ìîðîçîóñòîé÷èâà. Easy join available
pipe-line systems, is readily amenable to bending by hand. Äâóõñîòìåò
the ðîâàÿ bight weighs less 20 kg. When mounting the weld, the brazing,
gluing the is not necessary. Labor-intensity of assemblies 3-4 time less on ñðàâíå
Nia with steel tubes.
