MAPEC® advanced solutions

Line pipe for oil and other combustible liquids, natural gas and other gaseous media

For particularly challenging and complex pipe-laying projects, we offer a range of MAPEC® advanced solutions. Besides a variety of options regarding the plastic coating‘s thickness and surface condition we also offer a plastic multi-layer system that meets the most exacting demands on mechanical strength.

The plastic-coated pipes are marked in line with the relevant standard. If required, additional markings can be applied to customer specifications. This also includes colored paint markings. After coating, the pipe ends are usually provided with temporary corrosion protection.

MAPEC® can be complemented with a fibre cement mortar top coat to DIN 30340-1. Various types are available to match the soil conditions of the project in hand. For pipelines subject to extremely high mechanical loads in stony or rocky terrain, or in subsidence regions. Like plastic coatings, FCM coatings, which are supplied in stone gray as standard, are also available in other colors, indicating the medium transported in the pipeline. Gas line pipe, for example, is given a yellow coating.

At the customer's request, all coatings can also be supplied to other international standards and individual customer specifications.


MAPEC® plastic coating with Rough Coating (RC) surface

with Tmax = 110 °C (higher temperatures on request)

Description
3-layer plastic coating (PE or PP) consisting of 1) Epoxy resin primer, 2) Adhesive and 3) PE/PP top layer with a special surface treatment in the form of rough coating

Product properties
Pipe coating system with high friction resistance

  • Onshore projects: Increased slip resistance when walking on or handling the pipes
  • Offshore projects: Higher sliding friction for increased safety against the pipe string slipping off the stinger
  • Offshore/heavy coat: Increased shear resistance between the concrete and the plastic coating.

PP corrosion protection coating for elevated service temperatures up to 110 °C. Coating for higher temperatures on request.

Range of application
Recommended where high friction resistance of the coating surface is a criterion.


MAPEC® plastic coating with special layer thicknesses and as an ideal substrate for further coatings (rough coat, GFRP, heavy concrete)

(HDPE) for a max. service temperature of 85 °C, or polypropylene for up to 110 °C

Description
MAPEC® 3-layer coating with special layer thicknesses (PE) or with layer thicknesses increased to customer specifications (PP), consisting of 1) Epoxy resin primer, 2) Adhesive and 3) Polyethylene/polypropylene.

Product properties
Special corrosion protection for line pipe (gas/oil, drinking water/waste water/brines, etc.)

Range of application
Buried pipe-laying in rock-free terrain.


MAPEC® plastic coating with color strip marking for all PE coatings to DIN 30670 and all coating thicknesses (standard, greater and special thickness)

Description
3-layer coating consisting of 1) Epoxy resin primer, 2) Adhesive and 3) Polyethylene with 4 or 8 (> DN 355,6 mm) longitudinal strips in the following colors:
blue (compressed air), yellow (gas), red (cable), green (water) and brown (flammable liquids); other colors on request.

Product properties
Durable continuous marking according to the intended pipeline medium

Range of application
In line with customer specifications.


MAPEC® multi-layer plastic coating system

Description
4-layer coating consisting of 1) Epoxy resin primer, 2) Adhesive and 3) Polyethylene layer with 4) polypropylene top coat.

Product properties
The polypropylene top coat serves for mechanical protection. The roughened PE surface provides for increased shear strength.

Range of application
Projects with increased requirements on the coating's mechanical strength, e.g. trenchless pipe-laying.


Fiber cement mortar coatings

MAPEC® can be complemented with a fibre cement top coat to DIN 30340-1. Various types are available to match the soil conditions of the project in hand. For pipelines subject to extremely high mechanical loads in stony or rocky terrain, or in subsidence regions.

Like plastic coatings, FCM coatings, which are supplied in stone gray as standard, are also available in other colors, indicating the medium transported in the pipeline. Gas line pipe, for example, is given a yellow coating.

MAPEC® plastic coating with FCM-N fiber cement mortar top coat

Description
3-layer coating to (PE or PP), consisting of 1) Epoxy resin primer, 2) Adhesive, 3) PE/PP layer, plus FCM-N top coat to DIN 30340-1.

Product properties
The FCM-N top coat provides for very high mechanical strength and integrated protection against buoyancy. In addition, there is no need for sand bedding (no landfill charges), the spoil can be re-used, and the coated pipes can be bent on site.

Range of application
Pipe-laying in stony and rocky terrain.


MAPEC® plastic coating with T-ribbing and FCM-S fiber cement mortar top coat

Description
3-layer coating (PE or PP), consisting of 1) Epoxy resin primer, 2) Adhesive, 3) PE/PP with co-extruded T-ribbing plus fused-on PE particles (rough coat) and FCM-S top coat to DIN 30340-1.

Product properties
The interlocking effect between the 3-layer coating and the integrated T-profile with rough-coat surface on the one hand and the FCM top coat on the other generates an extremely strong adhesive bond. The advantages: fractures and cracks are reduced to a minimum because excessive stresses are avoided; increased shear resistance between the concrete and the plastic coating.

Range of application
The combination of mechanical protection and shear force transmission makes this coating type specially suited to trenchless pipe-laying projects.


MAPEC® plastic coating with thick-layer FCM top coat (FCM-N / FCM-S)

Description
3-layer coating (PE or PP), consisting of 1) Epoxy resin primer, 2) Adhesive and 3) PE/PP layer, plus FCM top coat to customer specifications.

Product properties
The thick-layer FCM top coat generates high mechanical strength and integrated protection against buoyancy.

Range of application
The MAPEC® + FCM coating system is particularly well suited as a heavy coat against buoyancy.
