Water Wall Panels Manufacturer India | Membrane Water Walls
100% Gas-Tight Membrane Panels with Automated Fin-to-Tube Welding
Membrane water wall panels form the perimeter combustion chamber of modern water-tube boilers. Fabricated on our automatic submerged-arc welding (SAW) gantries, our gas-tight panels eliminate fugitive flue gas egress, lower refractory maintenance costs, and provide maximum radiant evaporative surface area for rapid steam generation.
What is Water Wall Panels?
Water Wall Panels (membrane water walls) form the perimeter furnace combustion envelope of high-pressure industrial and power boilers. Modern Boilers Pvt. Ltd. fabricates 100% gas-tight membrane water wall panels up to 12 meters long by 1.8 meters wide on automated twin-wire submerged-arc welding (SAW) gantries. Fabricated with ASTM SA210 Grade A1 / SA106B seamless tubes and IS 2062 / SA387 Gr. 11 membrane flat bars, our water walls prevent flue gas egress, eliminate heavy refractory maintenance, and maximize furnace radiant heat absorption with certified IBR Form III-A inspection.

Our heavy-wall distributor, collector, and mixing steam headers are designed to handle pulsating steam dynamics and thermal expansion cycles. Built from seamless alloy pipes with hot-pulled extruded stubs or full-penetration welded forged weldolets, our headers eliminate stress concentration points and flow turbulence.
Specifically engineered for the aggressive turbulence inside AFBC (Atmospheric Fluidized Bed Combustion) furnace beds. Our studded bed coils utilize automatic capacitor-discharge welded alloy studs that anchor protective refractory matrices, dissipating abrasive bed particle impacts while maintaining superior in-bed evaporative heat transfer rates.
Generating bank tubes connect the upper steam drum to the lower mud drum in bi-drum water-tube boilers. Precision bent on computerized mandrel benders, each tube is guaranteed to exact curvature templates. Specially annealed tube ends ensure zero-leak roller expansion tightness into drum tube holes without work-hardening or micro-cracking.
