Import Boiler Membrane Water Wall — Buy in wholesale FOB from Supplier in China

The Boiler Membrane Water Wall from Shandong Hengtao Energy Saving & Environment Protection serves as the primary radiation heat surface within circulating fluidized bed boiler chambers, designed to withstand the intense thermal cycling and pressure conditions characteristic of CFB systems. The membrane construction welds tubes together with flat steel strips, forming a gas-tight envelope that eliminates refractory requirements and reduces maintenance exposure. This design typically accommodates working pressures up to 9.8 MPa or higher depending on boiler classification, with tube dimensions commonly ranging from 51 mm to 76 mm outer diameter in standard carbon or alloy steel grades. The supplier operates from Gaomi City in Shandong Province, a region with established heavy manufacturing infrastructure for power plant components.

The tubes are fabricated from 20G, 15CrMoG, or 12Cr1MoVG steel grades typical for boiler pressure parts, selected based on steam temperature and pressure ratings at the design stage. Fin bar material matches the tube metallurgy to ensure consistent thermal expansion and weld integrity across thousands of cycles. Tube wall thickness follows GB/T 5310 or ASME SA-210/SA-213 standards, with typical values from 3.5 mm to 6.0 mm depending on design pressure and corrosion allowance. The membrane panel is pre-assembled in sections with precisely located hand holes, observation ports, and burner openings machined to the boiler designer's drawings. Protective coatings or shot blasting may be applied prior to shipment to prevent oxidation during transit and site storage.

Power generation utilities, petrochemical complexes, and large industrial steam users deploy these membrane water walls in new construction and retrofit projects where improved combustion efficiency and lower emissions are targeted. The gas-tight construction enables better control of excess air and supports the low-NOx combustion strategies now standard in CFB designs. Buyers should confirm with Shandong Hengtao the exact tube pitch, fin width, and header connection details to match their boiler designer's specifications, as these vary with boiler capacity and steam parameters. Shipping terms, lead times, and certification packages including material mill test reports and non-destructive testing records should be negotiated directly with the supplier before contract placement.

Shandong Hengtao Energy Saving & Environment Protection is located in Gaomi City, Weifang, within Shandong Province in eastern China. The company carries a harbor trust tier on the platform, with a response rate of 0.00 percent and an average response time of zero hours recorded. The supplier's registered address places it in a province with substantial concentration of boiler and pressure vessel manufacturing, though buyers should independently verify production capacity and quality system certifications before committing to large orders. The listing does not specify the year of establishment, registered capital, number of employees, or annual turnover, so these details must be confirmed directly with the supplier.

The source description references ISO and CE certifications, but buyers should request current certificate copies with scope and expiry dates, as the listing itself does not display verification documents. The company positions itself in the energy saving and environmental protection sector, suggesting product focus on boiler efficiency components rather than full boiler boilers or EPC services. No client references, export destinations, or installed base figures appear in the available data. Prospective buyers are advised to conduct factory audits or third-party inspections given the critical safety nature of boiler pressure parts and the absence of detailed verification signals in the current profile.
