UBO-UM PIPELINE WRAP-AROUND CONCRETE WEIGHTS
The UBO-UM weights are designed to ballast the pipelines with a diameter from 530 to 1420 mm inclusively, when going through marshes, flooded lands and river valleys.
The UBO-UM weight consists of two ferroconcrete blocks with protective pads made of polymer rockshield (SLP) and two pairs of soft connecting belts (MSP) made of technical textile (or woven bands) with a minimum designed safety margin of 4; the bands hold the ferroconcrete blocks on the pipeline.
The climate and location category is UKhL 1, according to GOST 15150.
