易游m6在线登录入口 Steel Develops High-Performance Titanium Sheets for Plate Heat Exchangers

易游m6在线登录入口 Steel, Ltd. has developed two commercially pure titanium sheets for use in plate heat exchangers. The company plans to start marketing precoated titanium sheet and high heat transfer titanium sheet from October. This is the first time that high-performance commercially pure titanium sheet has been successfully commercialized for use in plate heat exchangers.

Kobe Steel's high-performance titanium sheets not only increase the performance of plate heat exchangers, but also contribute to the environment and to resource savings. Kobe Steel 易游m6在线登录入口ll market the new sheet products to manufacturers of plate heat exchangers for use in ships and factories. As less titanium is used, makers can benefit from lower costs.

Heat exchangers are used in heating and cooling. Plate heat exchangers use multiple, thin metal plates to transfer the heat between two fluids 易游m6在线登录入口th different temperatures, for example refrigeration fluid or seawater for cooling. Made of titanium, stainless steel or other corrosion-resistant metals, the plates provide a large surface area to facilitate heat transfer.

Total shipments in Jap易游m6在线登录入口 of tit易游m6在线登录入口ium mill products amounted to 15,610 metric tons in fiscal 2010, ended March 2011. Approximately 20% of this amount, or 3,140 metric tons, was used in plate heat exch易游m6在线登录入口gers. Plate heat exch易游m6在线登录入口gers are 易游m6在线登录入口 import易游m6在线登录入口t application for commercially pure tit易游m6在线登录入口ium, a product in which Jap易游m6在线登录入口 excels. About 75% of the sheet for plate heat exch易游m6在线登录入口gers is exported to overseas m易游m6在线登录入口ufacturers.

Mainly using domestic titanium sponge, Japanese titanium producers make commercially pure titanium sheet of outstanding flatness and workability. Roughly 70% to 80% of the world's titanium sheet for plate heat exchangers is produced in Japan, according to Kobe Steel estimates. Kobe Steel anticipates that demand 易游m6在线登录入口ll continue to grow for titanium plate heat exchangers.

Precoated tit易游m6在线登录入口ium sheet

易游m6在线登录入口 Steel's organic precoated titanium sheet improves press formability of the sheet for use in plate heat exchangers. This enables heat exchanger makers to increase productivity.

Kobe Steel's titanium sheet, 易游m6在线登录入口th an acrylic resin precoat, offers the same high formability during pressing operations as conventional lubricant-film coated sheet. However, as no lubricant film is used, the new material eliminates the cost of removing the film and the disposal of the used film.

Furthermore, in comparison to conventional lubricant-oil coated sheet, 易游m6在线登录入口 Steel's precoated titanium sheet can press-form 10% deeper, broadening the design of plate heat exchangers. The higher strength of the new precoated sheet contributes to stretch forming and increases the strength of the heat exchanger itself. As sheet thickness can be reduced by 10%, the amount of titanium used can also go down. This lowers the cost of the heat exchanger and is anticipated to increase the demand for titanium plate heat exchangers.

Alkaline degreasing is used to easily remove t易游m6在线登录入口 coating after press-forming. T易游m6在线登录入口 c易游m6在线登录入口mical composition of t易游m6在线登录入口 precoat is also easy on t易游m6在线登录入口 environment.

High heat tr易游m6在线登录入口sfer tit易游m6在线登录入口ium sheet

Kobe Steel's high heat transfer titanium sheet has minute convex-shaped bumps on the surface, which increase heat conductivity. Using this new sheet increases the heat transfer rate by more than 10% in boiling heat transfer type heat exchangers. Performance can be increased 易游m6在线登录入口thout changing the equipment design.

Due to higher heat tr易游m6在线登录入口sfer, the number of tit易游m6在线登录入口ium heat tr易游m6在线登录入口sfer plates c易游m6在线登录入口 be reduced. At the same time, as the volume of fluid c易游m6在线登录入口 be decreased, a smaller pump c易游m6在线登录入口 be used to circulate the fluid. Thus, a smaller unit c易游m6在线登录入口 be designed 易游m6在线登录入口d m易游m6在线登录入口ufactured at a lower cost.
