The present invention provides a corrosion-resistant structure for a high-temperature water system comprising: a structural material 1; and a corrosion-resistant film 3 formed from a substance containing at least one of La and Y deposited on a surface in a side that comes in contact with a cooling water 4, of the structural material 1 which constitutes the high-temperature water system that passes a cooling water 4 of high temperature therein. Due to above construction, there can be provided the corrosion-resistant structure and a corrosion-preventing method capable of operating a plant without conducting a water chemistry control of cooling water by injecting chemicals.

A multilayered corrosion and anti-galling coating for threads and wearable materials is a liner that can be superimposed onto the surface of a device in order to protect the surface from environmental hazards. To accomplish this, the coating has a base adhesive layer, an intermediary insulation layer, an interstitial adhesive layer, and a lubricating material layer. The base adhesive layer adheres to the device's surface thus enabling the coating to form a sealing liner. The intermediary insulation layer is positioned in between the base adhesive layer and the interstitial adhesive layer. As a result, the intermediary insulation layer prevents negative chemical interactions between the base adhesive layer and the interstitial adhesive layer. The lubricating material layer is super imposed onto the interstitial adhesive layer to provide a friction-reducing coating for the device's surface.

A swivel joint includes a first pipe section and a second pipe section. The pipe sections may define a flow path via which fluid passes through the swivel joint. One or more surfaces proximate a junction of the first pipe section and the second pipe section may be selectively coated to resist wear from erosion, corrosion, and or abrasion.

A thick-wall compression pipe fitting, comprising: a thick-wall fitting body for connecting arranged between two thick-wall steel pipe bodies for connection, wherein a sealing ring, a positioning retainer and a teeth ring is disposed between said thick-wall fitting body and said thick-wall steel pipe bodies. Said thick-wall fitting body includes a middle connecting section, a first flared section and a second flared section extending to both sides to adopt a thick wall metal pipe. A special crimping tool is used to deform the fitting body for crimping to compress the socket section of the fitting body having a sealing ring and a high-strength teeth ring, so that the sealing ring in the socket section groove seals the steel pipe to stop leakage, wherein the high-strength teeth ring shrinks and firmly fastens the steel pipe so that the connection between the fitting body and the steel pipe can be completed instantly.
