These Pipes are resistant to physical, chemical and technical effects at the depths of 1 – 15
meters and temperature range of -40ºС - +90ºС. At the same time, corrugated Pipes prolong operating
life of engineering facilities, facilitates their repair in minimum loss of time.
Depending upon the sphere of application, corrugated pipes in STP are manufactured in three colors:
red – for power transmission lines, blue – for telecommunication lines, black – for remaining purposes.
Smooth inner surface reduces friction to minimum.
