EVOCAB STING


EVOCAB STING cable protection pipes are made of high-density polyethylene (HDPE) and designed so that they can withstand loads caused by soil and vehicles.

STING type pipes have a smooth inner and outer surface. These pipes can be used to protect and insulate cables in underground installations made using the method of directional drilling. The cable protection pipes for trenchless installations are available in pieces of various lengths and in rolls.

  • Available sizes: DN/OD 50 .. 500 [mm]
  • Compression strength class: 1250
  • SDR class: from 17.6 to 11*
  • MRS class: 10

*can be specified on a request

  • Advantages
    • Quicker, more convenient, and cost-efficient construction of cable networks using the method of horizontal directional drilling
    • By using butt fusion method pipes are easy to interconnect
    • The pipe marking also includes length marks to determine installation length
    • The materials used to ensure that the conduits are environment-friendly and feature a long-term resistance against the effects of the aggressive substances present in the soil
    • Cables can be quickly replaced without additional earthwork
  • Recommended application

    The STING pipes can be used to protect and insulate cables in underground installations made using the method of directional drilling. They are especially suitable for use in systems requiring a high compression strength, e.g. under roads, squares, etc.

    By design, they are made for cable protection using the conventional method of installation – pulling by wire.

    In some projects, depending on the technology of directional drilling, properties of the soil, angle of pulling, distance and depth of pulling, project-specific pipe with an adapted (custom) thickness of the wall can be ordered.

    • If pulling lasts longer than 30 minutes, these values must be reduced by 10%
    • if pulling lasts longer than 20 h, the values must be reduced by 25%
    • In the case of additional bending loads, the corresponding reduction must be taken into account.
