Abstract

La présente invention a pour objet un procédé et une charge explosive, notamment pour enlever des depôts dans des tuyauteries et appareils chimiques. Le procédé est caractérisé en ce qu'on ménage dans le dépôt formé sur la paroi intéressée des alvéoles repartis de façon appropriée et destinés à recevoir une charge explosive qui comporte une enveloppe cylindrique 2, dans laquelle est placée une substance explosive 3, délimitée d'un côté par une surface hémisphérique 5 de rayon correspondant au rayon intérieur de l'enveloppe, la charge étant terminée par un chapeau 8 destiné à recevoir une capsule d'amorçage. Elle se rapporte au domaine du génie chimique.
