Geometry survey

Before in-line inspection, it is necessary to check that there are no obstruction to the passing of in-line inspection tools. For these purposes, an electronic multi-channel geometry pigs is used, which detects dents, corrugation, ovalities, bends and pipeline arrangement elements.


Geometry Tools 

Electronic geometry pigs are equipped with a navigation unit that allows to create a pipeline log with geodetic coordinates plotted. 

1.5 Dn

Minimum pipeline bend radius

0.85 Dn

Minimum passable diameter

up to 4 m/s

Optimal tool speed
