Mainly used for protection of thermometric elements, to isolate them from outside and reduce or prevent them being corroded, oxidized or damaged during use.
Product Specification / Models
Stock size of protective tube: outer diameter 3mm to 25mm, maximum length 2500mm, wall thickness by dimension scale of product 0.5mm to 4mm. Stock size of insulation tube: outer diameter 1mm to 8mm, with single orifice, double, four or more orifices in diameter 0.5mm minimal, maximal length 2600mm, all dimensions can be customized according to user demands. More at Chemical and Physical Index Table.
Application / Models
During use, the thermometric element insulated well put into the protective tube, and then open end and the couple end are sealed with high temperature clay. When in measurement, the sealed end is inserted into the temperature measuring zone, and it is best to prevent shock cooling or heating from damaging protective tube during use.
Tangshan Keshuo special ceramics manufacture Co., Ltd is an independently managed enterprise integrating scientific research, design, production and sale. Founded in 1997, the company has become a main manufacturer of domestic industrial ceramics through more than ten years of development and improvement. Apart from domestic market, its products are also sold in America, Britain, Germany, Russia, etc.
The company mainly produces alumina, zirconia and magnesia industrial ceramics and high-tech refractory materials, and owns multiple patent technologies. In order to maintain the dominant position of the company in the same industry in the aspects of technology and production, the company strengthened innovation of the original process technology, and was newly equipped with a high temperature kiln and pushed slab kiln production line in 2011.
In order to meet the increasing demands of customers and further expand the scale of production, research and development, our company newly built a 40-mu factory in Fengnan Littoral Industrial Area in 2012, and the factory is expected to put into production in July 2013.
