Alumina Ceramic Furnace Tubes

Our alumina ceramic furnace tubes are refractory ceramic tube components specially designed for high-temperature furnaces. They have excellent high temperature resistance and thermal shock resistance, and can work stably for a long time in a high-temperature environment above 1600℃. They are core furnace components of various experimental electric furnaces and industrial sintering furnaces. As the core component of a high-temperature furnace, alumina ceramic furnace tubes directly determine the temperature uniformity and service life in the furnace. We use high-purity alumina raw materials and special sintering process to prepare them. The internal structure of the furnace tube is dense and uniform, and will not deform and crack at high temperatures. At the same time, it has good air tightness, which can meet various process requirements such as vacuum sintering and atmosphere sintering.

Our alumina ceramic furnace tubes optimize the thermal stability formula of the tube body, greatly improving the thermal shock resistance, can withstand frequent temperature rise and fall shocks without cracking, and effectively extend the service life of the furnace tube. We can customize different pipe diameters, wall thicknesses and lengths according to customers' furnace body sizes, and support customization of special-shaped furnace chambers and variable-diameter furnace tubes. Each alumina ceramic furnace tube undergoes high temperature test and air tightness test before leaving the factory to ensure that the product performance meets the standard. With stable high-temperature performance, our furnace tubes have been widely used in high-temperature sintering and heat treatment processes of major scientific research institutes and industrial enterprises.

We are an original factory with over ten years of production experience in high-temperature industrial ceramics, with a 3,000㎡ standardized production workshop, equipped with professional production equipment such as large-diameter high-temperature tunnel kilns, vertical sintering furnaces and large extrusion equipment, with a monthly production capacity of up to 5 million ceramic components. We have a professional production and technical team of 30 people, which independently completes the whole process from raw material formulation, molding and sintering to finished product inspection. It can produce various large-size and high-performance alumina ceramic furnace tubes. The products supply the domestic market and are exported to overseas markets such as Europe, the Middle East and the United States.

We implement strict high-temperature performance control standards for alumina ceramic furnace tubes. Each batch of products undergoes high-temperature sintering test, thermal shock test and air tightness test to ensure that the high-temperature performance and sealing performance of the furnace tubes meet the standards. During the production process, the wall thickness uniformity and dimensional accuracy of the tube body are strictly controlled to ensure uniform temperature in the furnace. 100% full inspection of appearance and dimensions is carried out before packaging to eliminate defects such as cracks and deformation. We support inspection by third-party professional institutions, and the products come with a one-year warranty. Non-artificial quality problems can be returned or replaced.

We provide perfect after-sales service for all alumina ceramic furnace tubes. Real-time schedule updates can be provided during order production to assist customers in confirming installation dimensions. The products come with a one-year warranty. If non-artificial quality problems such as cracking and deformation occur within the warranty period, we can negotiate return, replacement or re-production. If the goods are damaged during transportation, we promise replacement for damaged goods and arrange reissue as soon as possible. For long-term cooperative customers, we can also provide technical support such as furnace tube selection and installation guidance to ensure the stable operation of customers' equipment.
