Product Description
The 15CrMoG Alloy Steel Superheater Membrane Wall Panel is manufactured with φ42*4mm chromium-molybdenum alloy tubes to GB5310 standard. This versatile panel provides reliable performance in superheater wall sections of industrial boilers operating at temperatures up to 500°C, offering an excellent balance of performance and cost for mid-range boiler applications.
Fabricated from 15CrMoG seamless alloy steel tubes per GB5310, containing approximately 1.0% Chromium and 0.5% Molybdenum. This Chinese-standard Cr-Mo steel is the direct equivalent to SA213 T12, providing improved elevated-temperature properties over carbon steel while maintaining good weldability. Membrane bars are produced from 15CrMo plate for consistent metallurgical properties across the entire panel.
- Mid-Range Temperature Performance: 15CrMoG alloy steel reliably operates at continuous service temperatures up to 500°C, ideal for superheater and reheater enclosure walls
- Improved Oxidation Resistance: Chromium content provides moderate oxidation protection in high-temperature flue gas environments, extending service life compared to carbon steel panels
- Good Weldability: Lower alloy content compared to T22/T91 grades simplifies welding procedures and reduces preheat/PWHT requirements, lowering fabrication costs
- GB Standard Certified: Full compliance with GB5310 and GB/T 9222 Chinese boiler pressure part standards, simplifying regulatory approval for Asian projects
- Versatile Application: Suitable for both new-build and replacement panel projects across multiple boiler types and capacities
Material verification per GB5310 including chemical analysis, tensile testing, and flattening tests. Visual and dimensional inspection of all panels. Hydrostatic testing and NDE per customer specification. Mill test certificates provided with each shipment.

High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler
High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler Product Introduction Water wall panels with pins usually laid vertically on the inner wall of the furnace wall, it is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace.It is the main type of evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.Because of both cooling
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME Product Description The boiler economizer is a device used to recover waste heat in industrial boilers, usually located at the tail of the flue of the boiler, which increases the feed water temperature and reduces fuel consumption by absorbing the heat of the flue gas, so as to achieve the effect of energy saving and emission reduction. But at the same time, as an environmental protection equipment, the

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
