Import Ceramic Round Single Bore Tube(Closed One End) — Buy in Bulk from Supplier in China

The Ceramic round single bore tube (closed one end) supplied by Engineering Ceramic Co., Ltd. is a precision‑made ceramic component featuring a single central bore and a sealed distal end. It is fabricated from Alsint C997 material that contains 99.7 % alumina, providing strong mechanical integrity and thermal stability. The closed‑end configuration offers effective containment for sensitive instrumentation in high‑temperature processes. The component conforms to the tight dimensional tolerances required by industrial applications.

High‑alumina ceramics such as Alsint C997 are standard for environments exceeding 1200 °C because of their low thermal expansion and resistance to thermal shock. Typical outer diameters for this product range from 10 mm to 200 mm, with wall‑thickness options between 2 mm and 10 mm, and surface finish usually specified as Ra ≤ 0.2 µm. Precision machining ensures bore diameter tolerances of ±0.05 mm, which aligns with common industry practice for thermowell and sensor protection parts. The material’s chemical inertness also makes it suitable for corrosive media.

Common users include manufacturers of automotive exhaust monitoring systems, aerospace engine components, and power‑generation equipment that require reliable temperature sensing. Suppliers often request flexible order sizes, and the listing notes that both FOB and CIF shipping terms are available together with payment options of T/T or L/C. Packaging is performed in robust crates to protect the tubes during transit. Prospective buyers should confirm the exact dimensions, material certification and delivery schedule with the supplier before placing an order.

Engineering Ceramic Co., Ltd. is located at Room 1019, Block A, Liansheng Plaza No.1 Renzai Bei Jie Road, Zhengzhou, Henan 450003, China. The company is classified as an imported‑tier supplier and carries a harbor trust tier on the sourcing platform. Its public profile shows a response rate of 0 % and no recorded average response time, indicating that inquiries may require follow‑up.

The firm lists ceramic components such as single‑bore tubes among its product catalogue and states compliance with ISO and SGS certifications for export quality. No additional corporate history, employee count or revenue figures are provided in the source data, and the listing does not specify minimum order quantities or lead‑time details. Buyers should therefore obtain these operational details directly from the supplier.
