FIELD: process engineering.
SUBSTANCE: invention relates to blasting of various surfaces. Distribution manifold is made up of a set of passive and active tube sections intercommunicated directly or by coupling 1. Tube sections have, at least, one support 3 of suitable shape to receive detachable or one-piece joint of jet-forming panel 4 with jet orifices of suitable shape, amount and arrangement. Tube sections are intercommunicated by, at least, one branch pipe with appropriate part of active tube section 2. Tube passive sections 6 are used for jointing, directly or via couplings, with auxiliary components of manifold and/or intercommunication of active sections. Active tube sections 2 with supports 3 are made by injection moulding of appropriate thermoplastic material.
EFFECT: simplified procedure, higher reliability of manifold.
