The PTBK frameless textile polymer container unit is designed to ballast main pipelines when the linear portion of the pipeline laid in the flooded land is constructed, rebuilt and overhauled when crossing any types of marshes and frozen soils.

The PTBK units are installed with a crane on the pipelines with a diameter from 219 mm to 1420 mm inclusively, in the trenches with a profile developed in accordance with SNiP-42-80, Paragraph 3.2, with a minimum bottom width equal to 2.2 diameter of the pipeline to be laid and a depth exceeding the ballasted pipeline by one meter and more.

The PTBK unit is operated at an ambient temperature from minus 60° to plus 40°.

The climate category is UKhL 1, according to GOST 15150.

Only mineral soil without any peat or snow with a minimum density of 1.4 t/m3 shall be used to fill the containers.

The PTBK frameless textile polymer container units are filled with a portable feed hopper.
