Tubular Insulation and Support for High-Temperature Equipment
Ceramic Fiber Tube is a tubular high-temperature insulation and electrical insulation component that can be used in industrial furnaces, electric heating equipment, thermal pipelines, and electrical systems.
Its tubular form allows the material to surround heating elements, steam pipes, or internal equipment components while forming a continuous insulation layer within a relatively limited installation space.
At room temperature, the listed thermal conductivity is 0.040–0.065 W/(m·K), helping reduce heat transfer through the structure.
The product can also withstand rapid heating and cooling at temperatures up to 1200°C, making it suitable for thermal equipment that operates with repeated heating and cooling cycles.
Thin-Wall Structure with Thermal Shock Resistance
In industrial furnaces, the tube can be used as an insulating support for electric heating elements.
It can also be installed in hot-face areas such as burner blocks and observation holes, where the component may be exposed to high-temperature radiation, flame, and furnace slag.
Wall thickness can be controlled from 1.5 to 5 mm. This relatively thin tubular structure can help the component fit around heating elements or within furnace assemblies where installation space is limited.
For pipeline insulation, Ceramic Fiber Tube can also be used as an insulation shell for overhead steam pipelines.
Its compressive strength is at least 0.2 MPa, and the tube can help accommodate deformation stress generated by the pipeline structure. The surface curing layer can also reduce penetration of rainwater and chemical media into the internal insulation layer.
Drawing-Based Diameter and Length Customization
The product can also be applied to tubular components in boiler furnace walls and high-temperature flue-gas systems.
Because equipment requirements vary widely, there is no single fixed inner diameter, outer diameter, length, or interface structure listed for all applications.
Nengcheng Crystal uses vacuum forming and finished-product machining capabilities to develop insulation sleeves and tubular special-shaped parts according to customer drawings.
Technical staff can discuss operating temperature, installation position, and load conditions before confirming the material grade.
Production personnel then complete forming and dimensional processing, while quality personnel inspect the condition of the finished product.
Samples and Packaging for Thin or Long Tubes
Samples can be made according to technical drawings or physical prototypes. Customized sample development normally takes 7–15 days, while customized production generally requires 20–45 days.
For Ceramic Fiber Tube with thin walls, long dimensions, or open structures, packaging can be selected according to transportation distance and product geometry.
Cartons, wooden cases, or wooden pallets are available. Finished products are normally checked before packaging, and third-party inspection is accepted.
If breakage or edge damage occurs during transportation, buyers can retain photos and videos. The factory can first arrange replacement, then review the packaging, loading, or transportation conditions and discuss the follow-up solution.
