Cable conduits

Description

When laying cables underground, protective conduit systems are typically installed to enable maintenance of the cable assembly throughout its service life.

Mannesmann offers customized connection technologies that allow high- and extra-high-voltage cables to be pulled into the protective conduit without damage.

Your benefits

  • Custom-designed sleeve connection to protect the cable during pulling
  • Prevents wear of connection seams in the field when using a sleeve or ZSM
  • Good thermal conductivity, additional shielding against electromagnetic fields
  • Defined coefficient of friction during cable pulling, determined in large-scale testing
  • High tensile forces and long distances in HDD made possible by steel material

External coating

Our pipes can be equipped with various external coatings directly at the mill. Typical systems that can be applied include:

  • HDPE or PP, also available in special designs according to customer requirements

  • FZM-S

  • HDPE + GRP

  • FBE + ARO

These factory-applied coating systems form the basis for sustainable corrosion protection and can be specifically tailored to the respective operating conditions.

MAPEC® 3-layer coating

The basis for many applications is our MAPEC® 3-layer coating, consisting of an epoxy primer, an adhesive layer, and a top layer made of polyethylene (PE) or polypropylene (PP). It provides reliable corrosion protection combined with high mechanical resistance.

Advanced coating systems for demanding conditions

Depending on project requirements, the coating systems can be adapted or extended:

  • Additional fibre cement mortar coatings enhance mechanical protection, particularly in challenging soil conditions

  • Special surface designs such as rough-coat or ribbed profiles improve friction and abrasion behavior, for example in trenchless installation methods

  • Polypropylene-based systems enable operation at elevated temperatures

The right solution for every application

Through the flexible combination of coating systems, our pipes are suitable for a wide range of applications – from conventional onshore projects to complex offshore installations.

This results in a customized protection concept that maximizes pipeline service life while meeting the highest standards of quality and operational reliability.

Our products are distinguished with
the label „OUR Sustainable Solutions“

More about Coatings
End preparation and protection, joining technologies
  • Special push-fit welded sleeve connection for damage-free pulling of cables into the cable protection pipe
  • ZSM connection from our partner Carl Hamm. Detachable and very quick to connect. Particularly recommended in confined spaces / where pre-assembly is not possible
  • Conventional butt weld connection; the weld root must be ground smooth to prevent cable damage

Installation techniques / Laying Methods

With appropriate protection systems, our pipes are suitable for all common trenchless installation methods as well as conventional construction techniques.

They have already been successfully used in virtually all installation methods – both onshore and offshore.

Thanks to tight diameter tolerances within a production batch, they also provide optimal conditions for automated welding processes.

Delivery and shipping

Mannesmann Line Pipe sees itself as a competent logistics partner whose responsibility goes beyond the proper and safe transportation of its products. Our objective is to ensure a safe and efficient logistics chain – from the mill to the agreed destination. In doing so, we place particular emphasis on minimizing environmental impact and reducing greenhouse gas emissions as much as possible.

When selecting logistics service providers, we focus on quality and reliability. This ensures that your orders are delivered worldwide on time and in top condition.

Our logistics services are characterized by:

  • Professional logistical support for your projects from initial inquiry through to delivery

  • Optimal selection of transport modes (truck, rail, and ship) based on cost efficiency and, in particular, environmental considerations

  • TÜV SÜD-certified load securing for truck transport

  • Expert support in the selection of storage locations and transport routes

  • Optional route planning, unloading and storage of pipes in stacks, as well as interface inspections during transshipment

  • Additional logistics services related to steel pipes

  • Professional customs and preferential origin handling (AEO certified)

Through increased use of rail transport, Mannesmann Line Pipe has significantly reduced transport-related emissions. In doing so, we actively contribute to climate protection.
