Specifies requirements for the design and fabrication of equipment to be lined and, the application and inspection of the lining along with provisions for any repairs. It applies to cold curing thermosetting resins. Guidance is also given on the properties of typical linings of this type and their application.

This Part of BS 6374 specifies requirements for the lining of equipment for the process industries using cold curing thermosetting resins.

It includes requirements for the choice of lining and its application and also requirements for subsequent inspection of the lining and the rectification of faults. It applies to equipment fabricated in metal or concrete.

The lining materials considered include epoxies, polyesters and furanes. Although not thermosetting resins, liquid elastomeric linings (such as polyurethanes) and solvated elastomeric linings (such as polychloroprene), are included since the same application techniques are used.

NOTE 1 The resins may contain fillers and/or reinforcing agents.

NOTE 2 The linings may be applied at the applicator’s works or on site.

Requirements for design and fabrication of the equipment and the state of preparation necessary for the surfaces to be lined are specified in Section 2. Requirements for storage, handling, transportation and installation of the lined equipment are specified in Section 8.

This Part of BS 6374 does not apply to paint coatings as dealt with in BS 5493.
