Depending on the composition of fluids, operating conditions and equipment use, our compatibility study can highlight the need to use thermoplastics for anti-corrosion purposes (the layer in contact with the product).

We can either use a thermoplastic on its own (referred to as “solid resin”), or we can use thermoplastic reinforced with glass fiber and polyester (“FRP”).

Using thermoplastic, especially if reinforced with glass fiber, means that we can significantly enhance the mechanical properties of the manufactured equipment (enhanced resistance to temperatures, internal and/or external pressures).

Specifically, the work consists in forming and welding the thermoplastic in order to obtain the desired part.

In this way, we can create all types of parts (squares, rectangles, circles, cones, etc.) in all sizes, from very small to very large (for examples, 6m in diameter in the case of cylindrical parts).

If required by the conditions of use, we can apply a polyester coating to the devices. We can also check the quality of the welds, in which case all welds will have a carbon braid so that we can carry out checks using a dielectric comb (non-destructive inspection of welds). If you wish, we can also check the quality of the welds using x-ray technology.

The thermoplastic will then be processed mechanically or chemically, in order to create ideal conditions for a good level of adherence between the polyester mechanical reinforcing part and the thermoplastic.

In this case, we carry out adherence tests to validate the work done.

The polyester coat is applied using filament winding or contact mold techniques, as per customer specifications.

The CITP Chaponnay plant (near Lyons) has a special thermoplastics forming workshop (Pehd, PPh, PVC, PVC-C, PVDF, ECTFE, FEP) and a joinery workshop to design tools for special parts.

Our welders have received training in accordance with the NFA88-800 standard for all transformed thermoplastics.

This technology applies to all devices which we manufacture: gas scrubbers, horizontal and vertical storage tanks, columns, and piping.

In addition to the above, CITP can also provide the following services on request:

  • Transport inside France and internationally (proximity to a river port).
  • Unloading and installation.
  • Contact molding on site.
  • Piping, studies, pre-fabrication and on-site assembly, testing.

We perform compatibility studies according to your fluids, their operating temperatures and operating conditions.

On completion of this extensive process, we are in a position to define the best dual-laminate thermoplastic materials.

We carry out equipment studies:

  • Design calculations;
  • The various controls defined in your specifications or/and the construction codes.
  • The manufacturer dossier.
