This part of ISO 9361 specifies the dimensions of indexable ceramic inserts with rounded corners, with cylindrical fixing hole, with 0° normal clearance. These inserts are primarily intended to be mounted by top and hole clamping or hole clamping alone on external and internal. Ceramic Tube insert also called ceramic ferrule which is inserted into the end of a heat exchanger tube to provide a protective function. The purpose of a ceramic tube insert is to either be sacrificial to the effects of inlet-end erosion, corrosion, impingement to induce a fluid to fall on the ID. Kyocera ceramic tubes are characterised by exceptionally high dimensional stability and corrosion resistance - even at extremely high temperatures. In this way, we ensure safe processes and provide optimum protection for your machinery and equipment. The Kyocera ceramic tube is available in. Since its foundation, Morgan Advanced Materials Haldenwanger developed into a leading global producer of high-tech ceramics. Technical ceramics manufactured by us meet the most stringent specifications With more than a century of experience in development and production to draw upon, CeramTec has established itself as one the world's top companies in. The size standards of ceramic tube s include specifications of diameter, length, wall thickness and other parameters.
