Import Ceramic Tube, Ceramic Pipes, Ceramic Sleeve — Buy in wholesale FOB from Supplier in China

Ruigu Precision Ceramic Parts Co., Ltd. supplies ceramic tubes, pipes, and sleeves made from 99.7% alumina, with outer diameters ranging from 5 mm to 50 mm and wall thicknesses between 0.5 mm and 5 mm. These dimensions are held to a tolerance of ±0.05 mm, achieved through precision grinding and sintering processes. The material composition ensures high thermal stability and electrical insulation, making the components suitable for use in high-temperature and high-voltage environments.

The ceramic components are manufactured using dry pressing and isostatic pressing methods, followed by firing at temperatures exceeding 1600°C. This results in a density of approximately 3.9 g/cm³ and a Vickers hardness of 1500 HV. While the supplier does not specify exact grain size, standard industrial alumina ceramics of this purity typically exhibit grain structures under 2 micrometers, contributing to mechanical strength and resistance to thermal shock. Surface finish is generally polished to Ra ≤ 0.2 μm for applications requiring minimal friction or contamination.

These ceramic parts are commonly purchased by manufacturers in the electronics, aerospace, and semiconductor industries for use in insulating sleeves, furnace linings, and sensor housings. Buyers in medical device assembly also source them for sterilizable components. The supplier does not state a minimum order quantity, but typical industry practice for custom ceramic parts ranges from 100 to 500 units per order. Packaging is usually in foam-lined cartons with individual compartmentalization to prevent chipping during transit.

Ruigu Precision Ceramic Parts Co., Ltd. is based in Guancheng, Dongguan, China, with a registered address indicating industrial manufacturing activity. The company specializes in precision ceramic components and operates as a producer rather than a trading entity, as indicated by its product focus and location in a known ceramics manufacturing hub. There is no public information on years in operation, workforce size, or revenue. The supplier's response rate and average response time are not available, suggesting limited engagement on the platform, but this does not reflect manufacturing capability.

The supplier does not list certifications, client names, or export history. It does not claim ISO compliance or any quality management system. The product description provided by the platform references ISO and certifications, but these are not attributed to Ruigu in the supplier profile and therefore cannot be assumed. Buyers should request documentation directly. The company appears to focus on custom fabrication for industrial clients, with no indication of retail or small-batch sales.
