Pipes for trench­less installa­tion

Description

Mannesmann pipes can be installed using various methods. Depending on the method chosen, we use materials and coatings suitable for our pipes that meet the required standards for burst resistance and shear strength.

Your benefits

  • All standard coating options can be produced in-house or in collaboration with partners
  • High-quality solutions proven in practice
  • Minimal impact on the environment during the installation process
  • Lower CO₂ emissions
  • High level of process integration with in-house production

Further Information

Lengths

The following delivery lengths are distinguished:

a) Mill lengths between 8 and 18 m are manufactured according to customer requirements. Due to the production process, minor manufacturing tolerances must be considered.

b) Fixed lengths with a permissible deviation from the ordered length of ± 500 mm. Up to 5–10% of the delivery quantity may deviate from the specified fixed length.

c) Exact lengths with the possibility to agree on tight tolerances for the ordered length.

Low CO2 Steel Grades

Together with our prematerial suppliers, Mannesmann Line Pipe GmbH is driving the transition towards a climate-neutral future. We are happy to advise you on our steel pipe solutions made from steel with a reduced carbon footprint.

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.

Flow Coat

Our standard solution, Flow Coat, provides a smooth surface, reduces friction losses, and supports efficient pipeline operation.

Additional solutions on request

Further internal coating systems – for example from partners such as NOV – are available on a project-specific basis, tailored to the respective media and application requirements.

Processing options

Exact lengths

Our pipes are supplied directly from production in lengths ranging from 8 to 18 meters. This enables efficient installation with reduced welding effort and optimized on-site logistics.

For applications with specific installation requirements or limited space, shorter pipe lengths can also be provided via our Pipe Service Center.

This ensures that our products not only meet the highest quality standards but also integrate seamlessly into your project workflows.

 

Beveling according to customer requirements

For optimal further processing and reliable welding, we offer a variety of bevel designs. The execution is carried out individually in accordance with customer specifications and tailored to the respective application and selected joining technology.

This ensures that our pipes not only meet the highest quality standards but also integrate seamlessly into your project workflows.

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.
