Tf ir - a cylindrical folded pipe with an integrated gapping ring.
Tfv - a pipe bushing with a stepped surface and sealing by a rubber sealing ring
The first group of numbers will set the diameter of the drainage passage in cm, the second - the size of the pipe in dm, the third - the group pipe bearing capacity.
For example, Tf 80.24-3 іг - folded pipe with integrated gum groove 80 cm in diameter, up to 24 dm, third groups pipe bearing capacity
