Carbon tube construction method:
1, The diameter of the bellows select Carbon: According to the cable diameter, the allowable voltage, current, and other conditions of the project selection.
2, Ditch digging project: According to relevant regulations and customer requirements trenching, its width and depth should be based on the laying of cables may be. From the single-walled carbon tube and the distance between the grooves is 50mm, tube and pipe between the 30mm.
3, Carbon threaded pipe laying: after the carbon tube into the ditch, where the curvature of the wound or to prevent extrusion, have to use cement potting. In two jacket pipe connecting the mouth shall brick and cement sheath tube head is fixed.
4, Carbon thread jacket pipe connection: When two single-walled carbon tube needs docking, the first joint rotation to the end of the takeover, then spin down to the end of another takeover, wound that is used PVC sealing tape can.
5. Backfill: Required to carbon thread jacket pipe laying is completed, with the original soil trenching to backfilling when and backfill compaction.
6. Note: The laying process, as a result of project needs, need two tubes or pipes while laying sand to be placed in the space between the pipe and tube and tamped, or distal end portion of the pipe, it is recommended Wei Shuai carbon tube pillow brand dedicated pipe fittings.
