Product Description
20G Industrial Boiler Water Wall Membrane Panel φ51×4mm Modular Section
The 20G Industrial Boiler Water Wall Membrane Panel with φ51×4mm tubes is a versatile, cost-effective modular panel solution for industrial steam generators ranging from 4 t/h to 130 t/h capacity. Pre-fabricated into manageable modular sections, these panels enable rapid on-site installation for both replacement projects and new industrial boiler construction.
Material & Construction
Manufactured from 20G seamless carbon steel boiler tubes per GB5310 standard. The φ51×4mm tube dimensions represent the most widely used configuration for industrial package boilers and small to medium capacity field-erected steam generators. Q235B membrane bars are joined to tubes using high-frequency resistance welding for a consistent, gas-tight seal. All panels are factory-welded into modular sections sized for standard container shipping and crane lifting.
Key Features
- Modular Pre-Fabrication: Factory-assembled panel modules reduce on-site welding by up to 60%, significantly cutting field installation time and labor costs
- Standard Industrial Dimensions: φ51×4mm and 80-100mm tube pitch dimensions match most common industrial boiler designs for direct replacement compatibility
- Economical Material Choice: 20G carbon steel provides reliable boiler service at a highly competitive price point, ideal for budget-constrained projects without compromising quality
- Quick Turnaround: Standard material inventory enables rapid manufacturing lead times (25-40 days) for urgent boiler maintenance or unplanned outage repairs
- Reverse Engineering Capability: Our engineering team can replicate panels from existing drawings, sample tube sections, or on-site measurements for exact replacement fit
Quality Assurance
GB5310 compliant material verification. Panel dimensional inspection including tube straightness, pitch accuracy, and panel flatness. Hydrostatic testing per GB/T 9222. All panels protected with anti-corrosion coating for storage and transport.
