PROCESS ENGINEERING CO.
Ralph Coidan Limited, Britain’s leading supplier of precision machined carbon and graphite components. Established in 1968, the company has built an excellent reputation for customer service and satisfaction worldwide. As part of Ralph Coidan Limited's policy of expansion and diversification Ralph Coidan Limited - Equipment Division was formed in 1976, to design and manufacture HYKARB impervious graphite exchangers and other corrosion resistant chemical plant and equipment.
All machining, impregnation and fabrication is carried out at the 600m2 factory
in Eaglescliffe, Stockton-on-Tees, UK, that employs approximately sixty personnel.
In order to offer a complete range of corrosion resistant heat exchangers and
chemical equipment Ralph Coidan Ltd.
The best quality graphite is used with the graphite core being one solid block. Superior Impregnation system using a process developed over 30 years. Thick graphite headers and connections used to increase the working pressure and eliminate breakage during installation. Thicker steel parts are used to enable higher working pressures. Fewer and no hidden gaskets used. Extra bolting included giving a more uniform loading on the gaskets.
The cartridge heat exchanger comprises a cylindrical core block, a steel shell and Hykarb end covers. The cylindrical Hykarb block is drilled for the process fluid and has slots on the shell side for the service fluid. The end covers are gasketed to the core block using steel pressure plates bolted to the steel shell.
Hykarb shell and tube heat exchangers are designed with a floating arrangement, easily removable end covers, completely removable tube bundle. They can be installed in a vertical or horizontal configuration.
Hykarb impervious graphite bursting discs are designed to protect process plant and equipment. The material, being completely resistant to corrosion from all but the strongly oxidising chemicals, is the natural choice for use by the chemical, pharmaceutical and process industries. For strongly oxidising chemicals discs can be lined with F.E.P. films.
