Thermal Shock Resistant Black Ceramic Tube / Black Ceramic Sleeve Bushing
Tag key words : Black Ceramic Tube / Black Ceramic Sleeve
Black Ceramic Tube may be fabricated in a number of ways, however, the most widely used method of ceramic tube fabrication is extrusion. Tube extrusion is valued for its ability to produce uniform goods, its high efficiency and the ability of extrusion equipment to run continuously. It begins when stock, or a collection of raw material, is held in a hopper above a conveyance channel, ready to be poured into another channel below. After it is released, it is heated until it reaches a molten state. Beyond sits a die, which is a plate with a profile cut into it. This profile matches the intended design of the finished product. To take on this shape, while still molten, the material forced through the die. Once it emerges on the other side, it is allowed to cool and harden. Another method that is sometimes used to make ceramic tubes is welding. Welding is a sculpture and/or fabrication process that creates new products by joining materials via fusion. In other words, welding is a process that melts the ends of two or more materials and joins them. Common types of welding include electrical welding and chemical welding. Subtypes of electrical welding include laser beam welding, arc welding and induction welding, while subtypes of chemical welding include solid reactant welding and oxyfuel welding.
In addition to the features mentioned above,Black Ceramic Tube is also electrically non-conductive, resistant to abrasion, resistant to compressive force and resistant to thermal shock. These characteristics increase their possible applications tenfold. Their electrical non-conductivity, for example, allows them to be adapted as insulators, channels through which electrical wires are passed and capacitors. Because they are abrasion resistant, they can be used as tubes through which abrasive materials pass, such as blasting equipment. Their resistance to compressive force and thermal shock make Black Ceramic Tube excellent candidates for the most high-stress and high-pressure applications, including those in aerospace, military and defense and deep sea missions. Some ceramic tubes are also porous, meaning that they work well with certain specialized telecommunications applications. The one weakness of Black Ceramic Tube is shear force. Therefore, in order to avoid damage, those using ceramic tubes should be careful to not subject them to the excessive tension or angular force. Ceramic tubes are powerful and well worth the investment. To find out more, reach out to an experienced ceramic tube manufacturer with your questions.
