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.

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. Non-destructive testing Visual / Dimensional Polymerisation Destructive testing Calcination test (loss on ignition) > in-house Peel test (separation) > in-house Tensile test > carried out by an approved external body Bending test > carried out by an approved external body

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.

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.
