Core business of the CMA division, throughout company history, the FGPR pipes and fittings section has always had a central role, leading VED to become a company that today is leader in the composites sector.

 

The CMA history in fibreglass begins last Century in the 1970’s, more than 40 years have passed from when the first productions of FGPR products, using the production system called “Continuos filament winding”, were started.

Throughout the years the company started to expand from design to production, installation to assembly, in a way that enhanced the range of products and services offered.

The FGPR (Fibreglass-Reinforced Polyester Resin) pipes and fittings represent the history of CMA.

The growth of CMA, which is strengthened by compliance to the main international standards UNI EN, ISO, ASTM, AWWA and BS, today has reached a level of experience that confirms us as partner of excellence, in support of our clients, able to

  • Complete the design
  • Prefabricate spools of piping
  • Manufacturing sections of the plant [SKID]

SKIDS IN FGPR

Productions made of FGPR piping and fittings on steel frame/base, completely prefabricated at the production plants and then sent to destination for connection and assembly at the reference plants such as, for example, water treatment systems.


The main advantage offered by prefabrication of pre-assembled modular systems (SKIDS), is represented by le ss production and set-up costs due to quicker in-house assembly and the use of less operational resources on-site.

Characteristics of FGPR pipe walls

Liner or chemical resistant layer:

Rich of resin, this layer carries out two fundamental functions, impermeability and chemical resistance. Each time therefore, based on the applications, it will be designed calibrating the composition of elements that it is made of;

Mechanical resistant layer:

This layer, differently from the liner, is instead rich of fibres. This contributes to giving the mechanical stress resistance characteristics (pressure, etc…). In its structure it is possible to insert aggregates which, depending on the application, are able to adjust viscosity, conductivity, flame retardant, each time, just to mention some of the peculiarities it is possible to operate on;

Gel coat or external layer:

Designed to guarantee complete impregnation of the surface fibres, depending on the applications, it can have additives such as agents blocking U.V. rays or even be protected by a layer of N.W.F. (Non Woven Fabric), which customers at times have requested in specific colors.

Composites innovation

For CMA by VED operating in the composites sector means continuous research and development of new products, new applications, new production techniques in line with the latest scientific research.

PIPES

They are generally identified based on pressure and hardness classes.

The main pressure classes are:
1,6, 10, 16, 20 Kg/cm2;

The main hardness classes are:
1.250, 2.500, 5.000, 7.500, 10.000, 15.000 N/m2.

 

The hardness is a measurement of the pipes capability to resist external loads
(E.g. empty, road loads, soil loads, ground water, etc…)

 

The diameters may be
from 25 mm up to 2400 mm.

FITTINGS

The main types of fittings are:

  • Continual radius bends;
  • Segmented bends;
  • Reducers;
  • Tee;
  • Flange;

Pressure classes:
1,6, 10, 16, 20 Kg/cm2;

Hardness classes:
1.250, 2.500, 5.000, 7.500, 10.000, 15.000 N/m2.

INSPECTION MANHOLES

Often made in masonry or pre-compressed reinforced concrete, in their fiberglass variant however they have many advantages compared to traditional production techniques, such as:

  • Lightness: with resulting cost reduction in terms of transportation and worksite handing;
  • Monolithic: these are built in one piece, this assists the operators for installation;
  • Type: it is possible to manufacture different types, from those for inspection to those for manoeuvre, catch basins, storm drains, etc…

JOINTS

There can be different types of joints (male-cup, flanged, wrapped, etc…), the ones we propose the most are sleeve with double or triple elastomeric lip. In this case hydraulic tightness if obtained by:

 

  • Pressure effect of the fluid transported against the rubber lips;
  • Compression of rubber profiles between the coupled surfaces. This way the seal is also obtained from the outside.
