CTRA produces a wide range of boiler-made equipment for chemical processing, including reactors, columns, decanters, mixers, gas coolers, gas scrubbers, odour scrubbers and absorbers, as well as their internal equipment.
All this boilerwork is designed by our departments to meet the dynamic and hydrostatic loads required by the various processes.
Thanks to the development and mastery of materials, CTRA is able to design a wide range of boilerwork, up to 6 m in diameter, to withstand the most corrosive fluids, whether they operate in a vacuum or at high pressure, from 50°C to 200°C.
Storage tanks used in the production and processing of corrosive fluids must meet customer safety requirements as well as the standards and regulations in force in the country of delivery.
CTRA offers a wide range of solutions for these storage tanks.
These can be built entirely in GRP or in GRP - Thermoplastic composites depending on the nature of the stored product.
Our tanks cover a range from 0.5m to 6m in diameter and from 0.5 m3 to 300 m3.
Other volumes can be designed and built on request.
CTRA supplies pre-packaged products for road, sea, air and rail transport.
Boilermaking equipment is placed on wooden cradles, with any openings systematically sealed with plywood protectors.
We can also make transport crates on request, adapting the packaging to the volume and mode of transport.
We have a skilled quality control team and a laboratory that enables us to carry out trials and tests to ensure the quality of raw materials and finished products.
As soon as we receive the raw materials, we carry out the necessary tests to ensure that they comply with the specifications provided by the suppliers.
Monitoring and controlling the manufacturing process
Ensuring traceability of manufactured products
Ensuring that finished products comply with CTRA standards and/or customer specifications by carrying out various in-process checks.

CTRA studies and proposes technical solutions for the transfer of all fluids over long distances, combining chemical compatibility with mechanical and abrasive resistance to ensure a long service life without routine maintenance.
The reference project carried out by CTRA in 2006 on behalf of OCP Morocco, which involved the construction of two Ø1800 phosphogypsum discharge lines with a total length of 8km, is a perfect illustration of this.
These pipes combine chemical, abrasive and mechanical resistance, and were buried at a depth of more than 12m to ensure a gravity flow rate for a charged fluid.
This project required the processing of 3400 tonnes of GRP vinylester over 24 months and was the subject of a case history.
Based on detailed studies provided by its customers or carried out by its design office, CTRA supplies high-performance GRP and GRP Thermoplastic piping systems in a range of diameters from 25 to 1500mm.
CTRA produces pipes and a full range of fittings in GRP and GRP-Thermoplastic in compliance with the standards and norms in the geographical area of the projects to be carried out.
The wide range of materials processed by CTRA guarantees its customers the best chemical resistance at a competitive cost.
CTRA has carried out a number of major projects, the largest of which involved more than 50,000 inches of welding in prefabrication workshops.
The transport of corrosive fluids by road, rail and water is highly regulated.
Design and quality requirements are very high because these hazardous materials are transported on public roads.
CTRA offers a range of solutions for these tank containers, which can be made of GRP / GRP Thermoplastic or GRP Thermoplastic.
