FAQ
Q1. What information should we supply to get a quote?
A1: Please offer the specification of ceramic tube, such as shape, dimension, quantity, application etc.
Q2. Is alumina ceramic safe to use?
A2: Alumina ceramic, composed mainly of aluminum oxide (Al2O3), is widely regarded as safe for various applications due to its biocompatibility, thermal resistance, and electrical insulation properties. Used in medical implants and dental applications, it is well-tolerated by the body.
Q3. Can alumina ceramic tubes be reused after use?
A3: Yes, alumina ceramic tubes can be reused after use, provided they are undamaged and free from contamination. Proper cleaning and inspection are necessary to ensure their suitability for subsequent applications.
A4: Yes, alumina ceramic tubes can be used in high-pressure applications. Their excellent mechanical strength and resistance to thermal and chemical stresses make them suitable for demanding conditions.
A5: Alumina ceramic tubes exhibit good thermal shock resistance, allowing them to withstand rapid temperature changes without cracking or breaking. However, it's essential to choose a tube with suitable thermal shock resistance for specific application requirements.
A6: Yes, many suppliers offer customization options for alumina ceramic tubes. Customization can include adjustments to size, shape, and additional features to meet the specific needs of your application.
