Traitement des matériaux
Cette entrée couvre une large gamme d’équipements et composants industriels utilisés dans la fabrication chimique, notamment les réacteurs, agitateurs, échangeurs de chaleur, colonnes de distillation, pompes, vannes et tuyauteries, dès lors que les surfaces en contact avec les produits chimiques sont réalisées dans des matériaux très résistants à la corrosion (alliages spéciaux, fluoropolymères, verre, graphite, etc.). Ces équipements sont essentiels pour la production ou la manipulation de substances chimiques sensibles, y compris celles pouvant servir à la fabrication d’armes chimiques. Leur exportation est strictement réglementée selon les directives du Groupe Australie.
