GUIDE RINGS (ONK)

GUIDE RINGS ARE DESIGNED: to construct crossings for the pipelines laid in protective casings under roads and railways and other engineering services in all of the climatic zones at a temperature from minus 40C to plus 50C.

Guide rings are manufactured only from the materials which ensure design integrity within the whole temperature range.

TECHNICAL CHARACTERISTICS OF GUIDE RINGS

Pipeline diameter, mm Ring mass, kg Distance between the rings, m
Gas pipeline Oil and oil product pipelines

159 2.4 6.0 5.0
219 3.6 6.0 5.0
273 4.2  6.0 5.0
325 4.8 6.0 5.0
377 6.0 6.0 5.0
426  8.8 6.0 5.0
530 9.9 6.0 5.0
720 15.9 5.0 4.5
820 17.3 5.0 4.5
1020 22.6 4.0 3.5
1220 29.0 4.0 3.5
1420 33.5 4.0 3.5

The exact distance between the guide rings is specified by the crossing project based on the allowable pressure on the insulation coating, allowable deflection of the pipeline between the legs and given the additional loads when the service pipe string is dragged through the protective casing (containment).
