Pipe polyethylene black PND d 20

Pipes PND water correspond to GOST 18599 - 2001 and are in large quantities used at construction and reconstruction of water supply systems, in systems of the automated watering, at the equipment of pools, for rising of water from artesian wells.

Pipes PND water are made in direct pieces on 12 m and bays on 100, 200 m. Pipes PND water have to have smooth external and internal surfaces. The insignificant longitudinal strips and a sinuosity which are not removing pipe PND wall thickness out of limits of permissible deviations are allowed. On nurzhny, internal and face surfaces of pipes bubbles, cracks, sinks, foreign inclusions are not allowed. Have color of pipe PND for water supply black or black with blue longitudinal marking strips in number of not less than three, evenly rapredelenny on a circle, or blue which shades is not regulated.

Main advantages of production:
Durability. The guaranteed service life of production makes 50 years - the probability of breakage of the pipeline because of freezing of liquids during this time decreases. Pipes pnd in climate of Russia are especially actual - they are not deformed, and change a form, subsequently coming back to the initial size and diameter.
Corrosion stability. Physical and chemical properties allow to use pipes pnd for transport of the most various substances. Stability of details even at interaction with aggressive substances allows to minimize need of regular repair.
Hygienic safety. Pipes polyethylene do not allocate in environment of harmful connections. Thanks to this factor they optimum are suitable for use in water supply systems, at construction of systems of the internal and external sewerage.
Ease of installation. Pipes pnd 5 - 7 times easier steel, the cost of welding of such details are significantly lower. At the expense of smaller weight it is more convenient to bring them to the destination, and considering their properties - application of pipes pnd is economically more expedient.
