Import Bolts Heater 1.2311(4)- 24.5x700 — Buy in wholesale FOB from Supplier in China

The product is a bolts heater model 1.2311(4)-24.5X700, designed for use in hydraulic machinery, steam turbines and other power‑plant components. It is manufactured from stainless steel grade 1.2311 (AISI 321) and measures 24.5 mm in diameter by 700 mm in length. Dongfang Yoyik Engnieering Co., Ltd. lists it among its power‑industry accessories such as sensors and transmitters. The heater is intended to provide reliable thermal resistance in demanding environments.

Stainless steel grade 1.2311 offers good resistance to oxidation at temperatures up to about 1150 °C, which is typical for this class of heating element. The electrical resistance of the rod is approximately 0.22 Ω per metre, a common value for this material. Surface treatment is usually a polished or shot‑peened finish to improve durability, and a ceramic coating is often applied as standard insulation. Dimensional tolerances are generally ±0.1 mm for diameter and ±0.5 mm for length, aligning with industry practice.

Typical applications include auxiliary heating of boiler feedwater, temperature control of turbine housings and pre‑heating of hydraulic circuits. Buyers such as power‑plant operators, equipment integrators and maintenance contractors source the item in bulk, often requesting wooden crates containing ten units each. Trade terms, incoterms and payment conditions are not disclosed in the listing and should be confirmed directly with the supplier. Because the supplier’s response rate is currently zero, importers should verify contact details and request a formal quotation before proceeding.

Dongfang Yoyik Engnieering Co., Ltd. is located at 4‑3f, Blg A, Huashan Platz, Deyang 618000, Sichuan Province, China. The company is classified in the harbor trust tier, indicating a moderate level of verification, though its current response rate is recorded as 0 % with no average response time. It specialises in supplying spare parts and auxiliary equipment for power‑generation facilities, including steam turbines, boilers, and related hydraulic components. The listing mentions a broad catalogue of items such as rotational speed sensors, laser sensors and thermal detectors, positioning the firm as a niche supplier for plant maintenance.

The supplier does not provide explicit details on minimum order quantities, pricing or lead times in the public data. It also does not state any specific certifications such as ISO 9001 or product‑specific test reports, so buyers should request such documentation directly. Communication channels appear limited given the zero response rate, so importers are advised to verify the contact information and request a formal quotation before committing. No additional corporate history, employee count or revenue figures are available from the source.
