Yes, Accuratus can custom fabricate any tube geometry not shown in the standard catalog list. Customers can call or send engineering drawings for quotation.

Mullite has a low thermal expansion coefficient, aluminum oxide is noted for its superior refractoriness, and sialon is an outstanding thermal shock resistant material.

The rods and tubes find a wide range of applications throughout industry and academia, particularly in demanding thermal, chemical, wear, and electrical applications.

Low cost, volume manufacturing processes are used to produce these tubes. They are extruded in smaller sizes and cast in larger sizes, then batch fired at high temperatures in specialty kilns to maintain dimensional integrity and consistent material properties.
