FIELD: construction.
SUBSTANCE: invention relates to methods to reinforce and/or restore metal panels, and also to reinforce pipelines and to attach branches to them. The specified methods are realised in five versions. According to the first version, the method to reinforce a metal structure includes operations of attachment of a reinforcement metal layer to a metal structure to create a space between them to form at least one cavity between inner surfaces of the metal panel and the reinforcement metal layer, injection of an intermediate layer made of non-vulcanised plastic material, into at least one cavity, and hardening of plastic material so that it adheres to the inner surfaces of the metal structure and the reinforcement metal layer. According to the second version, a vessel panel is reinforced using the method of the first version. According to the third version, a branched pipeline is connected to an existing main pipeline using the method of the first version. According to the fourth version, a reinforced metal structure is proposed, which is produced by the method of reinforcement according to the first version. According to the fifth version, a main pipeline is proposed with a branching pipeline attached by the method of attachment according to the third version.
EFFECT: invention provides for structural reinforcement or restoration of metal panels with stiffening elements without necessity to remove stiffening elements and other parts.
