ACTP is a structure which proposes a service of advice and technical support for all plastic or FRP (Vessels, tanks, piping…). ACTP groups engineers and technicians with a long experience in the implementation of thermoplastics or thermosetting materials.

Preliminary Design

During the preliminary design phase ACTP can offer expertise on the following problems:

>Material selection:

  • Selection and definition of materials adapted to your processes.
  • Work with the R & D laboratories of the leading suppliers of resin or thermoplastic.

> Design and feasibility:

  • Evaluation of the design and the feasibility of your complex equipment.
  • Adapting the design of existing steel equipment to be compatible with that of plastic construction.

> Technical specifications:

  • Assistance in the drafting of technical specifications.

> Help in preparing your budgets:

  • In the case of specific or complex equipment, ACTP can prepare the prebudgets.

Audit of the manufacturers:

  • Visit and evaluate the eventual manufacturers selected for building.
  • Experiences in monitoring manufacturers low cost region (Asia; MiddleEast).

Detail Design

In the case of complex equipment, ACTP can perform technical studies including the following services:

> Calculation note:

  • Pre dimensioning
  • Pressure vessel in accordance with European or US standards
  • Checking the design conditions for earthquakes

> General arrangement drawings for going out to tender

> General arrangement and details drawings

> Developing of manufacturing specifications

Supervision Project

ACTP can provide technical support for the monitoring of your projects during the different steps

 > Implementation of an organization for the follow-up of the manufacturers

> Checking of the documents issued by the manufacturers

  • Calculation notes
  • Drawings
  • Manufacturing procedures
  • ITP

> Attendance and technical support during meetings

> Construction follow up in workshop or on site

> Final inspection and acceptance


ACTP can intervene in the following cases:

> Damaged equipment

  • Assessment of the extend of damage
  • Budget and feasibility of repair
  • Repair procedure

> Assessment of the condition of piping

  • Expertise of the existing lines
  • Implementation of an inspection and/or replacement schedule
  • Budget


ACTP can give the following training:

> Knowledge of plastic materials

> Design of plastic equipment

> Rules relating to the application concerning chemical engineering

> Monitoring and inspection:

  • Creating of inspection and test plans
  • Training of local inspectors


ACTP offers a free service for answering basic questions concerning all the problems related to the design and construction of thermoplastic or thermosetting equipment:

> Codes and practices or reference documents

> Contacts information for potential manufacturers

> Implementation of an organization and / or strategy

Construction of a railway roof for high-speed rail. This roof is made up of an assembly of sandwich panels: Epoxy resin + glass fiber and a PET foam core.

TECHNIP-KREBS Mixer Settlers :

Derakane Epoxy Vinyl Ester Resins – Case History
Installed in 2014 at AREVA’s McClean Lake – Extraction Solvent Plant ( Uranium Mill), Saskatchewan, Canada.
TECHNIP Lyon (France) / ZHONGYI (China) / AREVA Resources Canada Inc. (Canada)
Due to fire retardant material request to respect ASTM E-84, DERAKANE 510 was used for the structural part and the corrosion barrier layer, both fabricated by hand lay-up.
To protect the equipment against electrostatic hazard, the corrosion barrier layer was made conductive to reach a surface resistivity lower than 106 Ohm. Accordingly, the corrosion barrier layer (3.3mm/130mils) was made of one carbon veil layer and one ECR-glass surface veil followed by 3 CSM layers 450 g/mÇ (1.5 oz/sq. ft.) with the addition of Ketjenblack EC300J from AKZO.
A hot air post cure was applied.
Organic phase: Kerosene + Amine + Isodecanol
Aqueous phase: liquor containing H2 SO4 ( 30 g/L),
Chloride (0.1 g/l), Uranium and Molybdenum
Maximum Operating Temperature: +50° C (122° F)
Design temperature: +65° C (149° F)
Design pressure: +0.01barg (+0,145psig) /-0,07barg (-1,01 psig)
Main Mixer Settlers dimensions : 9300 x 2000 x 2500 mm (366x79x98 in)
For this project, 16 Mixers Settlers, 16 Interphase Regulators and 2 After Settlers were designed and fabricated following the EN 13121 for a service life of 30 years.
