It is manufactured from carbon steel and features a GB3274 enamel coating on the heat-transfer tubes. The unit recovers heat from boiler flue gases, thereby reducing the temperature of exhaust gases and improving overall boiler efficiency. The supplier describes the product as a solution for ash collection, low-temperature corrosion and stable combustion.
Carbon steel provides the necessary strength for the high-temperature environment, while the enamel coating offers corrosion resistance and easy cleaning. In the air-preheater market, typical tube diameters range from 40 mm to 60 mm and operating temperatures can reach up to 500°C, which matches the performance envelope of this product. The enamel complies with the GB3274 standard, a common requirement for industrial heat-exchange equipment. Such characteristics make the preheater suitable for both new installations and retrofits of existing boiler systems.
Primary users include power-plant engineers, industrial boiler manufacturers and contractors responsible for plant upgrades. Importers should discuss minimum order quantities, delivery schedules and payment conditions directly with Shandong Hengtao Group, as these details are not disclosed in the listing. The supplier’s harbor-tier verification indicates that basic company information has been validated, but prospective buyers must obtain full technical data sheets before confirming a purchase.

Before placing an order, importers should request the full technical data sheet, material certification and the GB3274 enamel compliance report. Confirm that the tube dimensions, operating temperature and pressure rating match the project requirements, and ask for a sample of the enamel finish if possible. Verifying these specifications reduces the risk of incompatibility with existing boiler systems and ensures compliance with local emission standards.
Logistics for shipments from Shandong Hengtao Group are typically arranged through the nearest seaport in Qingdao, but the exact Incoterms and freight forwarder must be agreed with the supplier. Because the response rate is currently low, buyers should obtain a written quotation that includes lead-time estimates, packaging details and payment terms such as letter of credit or advance payment. Clarifying these points early prevents delays in customs clearance.
Quality assurance can be reinforced by scheduling a third-party inspection at the factory before loading, focusing on enamel integrity, tube straightness and dimensional tolerances. Request inspection reports covering visual enamel coating checks, dimensional measurements and pressure testing. Ensure that the supplier provides a mill test report, a certificate of conformity and packing lists so that the imported preheater can be verified upon arrival.
