The **CODAP** (Code for the construction of unfired pressure vessels) is a **French code** developed by **SNCT** (Syndicat National de la Chaudronnerie, Tuyauterie et Maintenance Industrielle). It governs the **design, manufacture, inspection and documentation** of **pressure equipment** that is **not heated by a direct flame**. ### CODAP standard requirements The requirements of **CODAP** are structured to ensure the **safety, reliability and regulatory compliance** of pressure equipment. These requirements cover every stage: **design, manufacture, inspection and documentation**. Compliant design **Equipment must be designed according to rigorous calculation rules**, taking into account the maximum allowable pressure, operating temperature, mechanical stresses, corrosion and fatigue conditions. Qualified materials **The materials used must be compatible with the requirements of the code**, particularly in terms of mechanical strength, chemical composition and corrosion resistance, and must be fully traceable. Controlled manufacturing processes **Manufacturing processes must be validated**, especially welding, which requires specific qualifications for procedures (WPS) and welders (WPQ). Mandatory inspection and testing **Non-destructive testing must be carried out at different stages of manufacturing**, such as visual inspection, dye penetrant testing, radiography, ultrasonic testing or magnetic particle inspection, depending on the required level of scrutiny. **A pressure test is mandatory** at the end of manufacturing, often a **hydrostatic test**, to verify the equipment's resistance to a pressure higher than the maximum operating pressure. Documentation and traceability **A manufacturer’s file must be compiled**, bringing together drawings, material certificates, inspection reports, welding procedures, qualifications and test records. Compliance with european Directive 2014/68/eu **Compliance with European Directive 2014/68/EU (PED)** is integrated, with specific requirements regarding CE marking, final inspection and the involvement of notified bodies. ## The FILAB laboratory supports you in carrying out CODAP analysis ### Why choose FILAB for CODAP analysis?

CODAP is used in sectors such as **chemicals**, **pharmaceuticals**, **energy**, **water treatment**, and even **biotechnology**. It is particularly relevant in contexts where the **European PED directive** (2014/68/EU) applies. Is CODAP an official standard? No, CODAP is not a standard in the ISO or EN sense, but a **recognized construction code**, often required as a **technical reference in industrial specifications**. It is compatible with the PED directive. Can the FILAB laboratory support me with a CODAP approach? Yes. At FILAB, we support you throughout the CODAP-related analysis chain: **- Material characterization** **- Batch qualification** **- Weld inspection** - **Expertise in the event of non-compliance**
