At present, the steam pipe of the ship mainly USES aluminum silicate encased with asbestos to achieve the goal of exhaustion. Moreover, the steam pipe was subjected to high temperature and soluble salt for a long time. For this reason, a series of water-glass adhesives can be used as coating materials on aluminum silicate substrate to form a coating layer of enamel-like structure. The thermal expansion coefficient is similar to that of pipe, and the thermal stress is small without cracking. In mechanical installation, components are usually bolted. Long - term exposure of bolted devices to air will lead to crevice corrosion. During the mechanical operation, the bolts sometimes become loose due to severe vibration. To solve this problem, the connecting members can be first bonded with inorganic adhesive in mechanical installation, and then connected with bolts. Such can have the effect that consolidate already, can have anticorrosive effect again.
