The paper proposes methods for protecting the internal silicate-enamel coating of pipes in field conditions. It is shown that the proposed methods are highly efficient for manual mechanical cutting, chamfering, cutting edges with abrasive tools with vulcanite cutting discs for welding, in manufacturing and assembling the engineering systems, transportation of aggressive products, and fire fighting systems.It is shown that the most appropriate method for preservation of the internal silicate-enamel coating is its preliminary annular incision and sizing of the cut place with a thin cloth (calico) impregnated with quick-drying glue, and clay coating protection from hot metal particles. This method is recommended to be used when cutting pipes, fittings, segments, processing their chamfers and cutting edges, in manufacturing of network nodes (fire-fighting systems) in field conditions.The proposed methods will significantly increase the operating life and reliability of engineering networks with silicate-enamel coating for the transportation of aggressive products and, as a result, technical safety of trouble-free facilities.
