Import Heat Surface Water Wall — Buy in wholesale FOB from Supplier in China

The Heat Surface Water Wall offered by Shandong Hengtao Group consists of a membrane panel formed by steel tubes welded together, optionally separated by a metal strip. These panels line the interior of a coal‑fired boiler’s combustion chamber, forming the evaporator section where water absorbs heat and converts to steam. The construction is described as a welded tube array that creates a continuous water‑filled surface. The supplier indicates that the panels are produced in a workshop equipped with automatic welding equipment.

The tubes are typically carbon‑steel, conforming to ASTM A36 specifications, which provides adequate strength for boiler pressures up to 2‑3 bar. Standard tube diameters in water‑wall panels range from 25 mm to 38 mm, and panel thickness is usually between 5 mm and 10 mm, both of which are common industry dimensions. Operating temperatures can reach up to 850 °C, and the panels are designed to achieve thermal efficiencies of 85‑90 % in heat transfer, which aligns with typical boiler performance criteria. The welded joints are inspected by visual and ultrasonic methods to ensure leak‑tight integrity.

Primary users are power‑generation plants and large‑scale industrial boilers that require reliable heat‑exchange surfaces. Shandong Hengtao Group notes export experience to Vietnam, Mongolia, Pakistan and Indonesia, suggesting familiarity with international logistics, though exact MOQ, lead time and incoterms must be confirmed with the supplier. Buyers should request detailed engineering drawings and material test certificates before placing a bulk order. The company highlights competitive pricing and a focus on consistent quality, but all trade terms are negotiable.

Shandong Hengtao Group is situated in Xiazhuang Industrial Park, Gaomi, Shandong Province, China, as provided in the supplier profile. The company holds a harbour trust tier but currently records a 0 % response rate, meaning that follow‑up communication may be necessary to obtain detailed quotations. Its listed capabilities focus on manufacturing boiler components, specifically water‑wall panels for coal‑fired boilers.

The workshop features automatic welding equipment and a workforce described as skilled and qualified. Export history includes shipments to Vietnam, Mongolia, Pakistan and Indonesia, indicating experience with cross‑border logistics. No further details on production capacity, certifications or client references are disclosed in the listing.
