Product Description

Our Membrane Water Wall Panel, also known as a boiler membrane wall or membrane tube wall, is a factory‑prefabricated radiant heating surface that forms the airtight enclosure of the boiler combustion chamber. Manufactured using submerged arc automatic welding, it consists of seamless steel tubes joined with flat steel strips to create a fully water‑cooled, gas‑tight panel that effectively absorbs high‑temperature radiant heat from the flame and flue gas, converting water into steam while reducing furnace temperature and preventing coking. This design significantly improves combustion efficiency by minimizing air leakage, offers fast thermal response for quick start‑up and shutdown, reduces the structural load on the boiler frame, and lowers on‑site installation time compared to traditional tube layouts. Available in carbon steel, alloy steel, or stainless steel, with tube diameters ranging from Φ28mm to Φ76mm and fully customizable dimensions, our panels comply with ASME, ISO, and GB standards, and are widely used in power plant boilers, CFB boilers, industrial steam generators, waste heat recovery systems, and biomass applications, making them an essential, cost‑effective solution for modern high‑efficiency boiler systems.

Application description

Membrane Water Wall Panels serve as the primary radiant heat‑absorbing surface inside boiler combustion chambers, converting water into steam or hot water by capturing high‑temperature heat from flames and flue gas. They are extensively used in coal‑fired power plants, circulating fluidized bed (CFB) boilers, industrial steam generators, waste‑heat recovery systems, and biomass‑fired units. The gas‑tight membrane structure significantly reduces air leakage, improves combustion efficiency, prevents slagging, and enables rapid start‑up and shutdown, making these panels an indispensable component for modern high‑efficiency boiler systems.

Production description

Our Membrane Water Wall Panels are manufactured using submerged arc automatic welding (SAW) on a dedicated production line, ensuring consistent weld penetration and a smooth, double‑sided finish. The entire process follows a strict quality control workflow that begins with raw material verification, followed by precision cutting, welding, dimensional inspection, post‑weld heat treatment (if required), and 100% non‑destructive examination (PT, RT, or UT) to guarantee flaw‑free joints. Each panel undergoes a hydrostatic pressure test at design pressure to verify its leak‑tight integrity before final surface coating is applied, and all production steps comply with ASME Section I, ISO 3834, and GB/T 16507 standards to ensure reliable performance in demanding boiler environments.

Shipping Packaging

Each Membrane Water Wall Panel is carefully packaged to prevent damage during transit and storage. The panels are securely bundled on reinforced steel frames with adequate support to avoid distortion, and individual layers are separated with protective padding to prevent scratching. For export shipments, the bundled panels are wrapped in waterproof and moisture‑proof materials, then covered with heavy‑duty woven fabric or shrink‑wrap, and finally strapped with steel bands for container or bulk vessel loading. Clear shipping marks, lifting points, and handling instructions are attached to each package, ensuring safe and efficient unloading and installation at the destination site.

FAQ

1. Can you customize the panel dimensions, materials, and tube sizes to match my specific boiler design?
Yes, we offer full customization. Tube outer diameters (Φ28–76 mm), wall thicknesses, fin/steel strip sizes, panel lengths and widths, as well as material grades (carbon steel, alloy steel, or stainless steel) can all be tailored to your engineering drawings and operating conditions. We work closely with your technical team to ensure a precise fit and optimal performance.

2. What quality standards and testing procedures do you follow?
Our manufacturing complies with ASME Section I, ISO 3834, and GB/T 16507. Each panel is produced using submerged arc automatic welding (SAW) and undergoes 100% non‑destructive examination (PT, RT, or UT as required), plus a hydrostatic pressure test at design pressure. Post‑weld heat treatment is applied when specified, and all raw materials are traceable with mill test certificates.

3. How are the panels packaged for export, and what is your typical lead time?
Panels are securely bundled on reinforced steel frames with protective padding between layers, then wrapped in waterproof and moisture‑proof materials, covered with heavy‑duty woven fabric, and strapped with steel bands for container or bulk vessel loading. Clear lifting points and handling instructions are attached to every package. Lead time generally ranges from 30 to 60 days after order confirmation, depending on quantity and complexity, and we provide regular production updates and coordinate shipping arrangements for timely delivery.
