Perguntas frequentes

What are the temperature resistance capabilities of alumina tubes?

We offer alumina tubes for continuous use up to around 1600°C and intermittent use up to 1700°C, depending on purity and structural design.

How strong and chemically resistant are Al2O3 tubes?

Alumina ceramic tubes have very high hardness, good wear resistance, and high bending strength. At the same time, they have excellent corrosion resistance to acids, alkalis, and most corrosive chemical media at high temperatures.

What are the electrical insulation properties of aluminum oxide tubes?

Alumina is an excellent electrical insulator with a volume resistivity exceeding 10¹⁴ Ω·cm, making it particularly suitable for applications requiring high temperature insulation performance.

What sizes and customization options are available for aluminum oxide tubes?

We can provide a variety of standard and customized specifications, including single-hole, double-hole and multi-hole tubes, and the outer diameter, inner diameter and length can be adjusted according to needs. At the same time, we can also customize single-end closed ceramic tubes, flange tubes and various special-shaped parts to meet your design needs.

How should aluminum oxide tubes be handled and maintained to ensure longevity?

In daily use, severe temperature shocks and mechanical collisions should be avoided; keep them dry and clean during storage, and be handled with care to prevent bumps; check regularly and replace worn or damaged pipes in time.

Do you offer custom sizes and shapes?

Yes, we are good at customized production. We can customize ceramic tubes of different lengths, diameters, wall thicknesses and complex structures according to the drawings or requirements provided by customers.

What is the purity level of the alumina used in these tubes?

We mainly use ≥99% high purity alumina, and we can also provide materials with different purities such as 95%, 96%, and 99.7% according to demand.
