Datang Finned Tube Powers a Major Gas Furnace Project in Kazakhstan
Across the vast landscapes of Central Asia, Kazakhstan’s industrial sector is embracing new opportunities. Recently, Datang Finned Tube successfully delivered a batch of high-performance gas furnace heat exchangers, custom-built for the Kazakh market. This achievement is not just a cross-border commercial collaboration, but a powerful testament to the strength of Chinese manufacturing and our commitment to international quality standards.
Project Success: High-Frequency Welded Finned Tubes for Gas Boiler Heat Exchangers in Kazakhstan
-
Client Location: Kazakhstan
-
Application: Industrial Gas Boiler Heat Exchanger
-
Core Product: High-Frequency Welded (HFW) Spiral Finned Tubes
-
Manufacturer & Supplier: Cangzhou Datang Steel Pipe Co., Ltd. (Datang Finned Tube)
The Challenge: High-Efficiency Thermal Performance Under Harsh Conditions
A leading energy equipment manufacturer in Kazakhstan was seeking a reliable supplier for a critical gas boiler heat exchanger(Finned Tube Heat Exchanger) project. Gas boiler applications demand extreme thermal efficiency, exceptional pressure resistance, and long-term durability against high-temperature flue gas corrosion.
Because the project was based in the CIS region, the technical specifications were incredibly stringent, requiring strict adherence to GOST or TU standards for the base pipes, alongside massive dimensions and tight tolerances.

The Datang Solution: Precision-Engineered Heavy-Duty Finned Tubes
Leveraging our 19+ years of manufacturing expertise in Yanshan (the world-renowned “Pipe Township”), Based on the client’s flue gas data, operating pressure, and thermal calculation models, Datang’s engineering team customized a replacement heat exchanger bundle utilizing High-Frequency Welded (HFW) Carbon Steel Spiral Finned Tubes:
-
Flawless Weld Penetration (100% Bond Rate): Utilizing our advanced high-frequency welding lines, we achieved a 99.8% weld bonding rate between the steel fin and the seamless base tube. This eliminated the thermal contact resistance entirely, ensuring maximum, uninterrupted heat transfer.
-
Optimized Fin Geometric Structure: We adjusted the fin pitch to perfectly balance the heat exchange area with the aerodynamic resistance of the gas-fired boiler’s exhaust, significantly minimizing ash accumulation.
-
Strict Inspection Protocols: Before shipment from our factory, every single finned tube underwent a comprehensive technical audit, including magnetic particle testing for welds and rigorous pull-out force tests to guarantee structural integrity under rapid thermal cycling.
High-Frequency Welded (HFW) Finned Tubes Specifications Delivered:
-
Base Pipe Material: Premium Steel conforming to strict GOST / TU Standards
-
Outer Diameter of Smooth Pipe: 159 mm (Heavy-duty industrial scale)
-
Wall Thickness of Smooth Pipe: 11 mm – 12 mm (Engineered for high-pressure safety)
-
Finning Tape Thickness: 2.0 mm (Robust fins for maximum heat dissipation)
-
Finning Pitch: 2 mm (High-density configuration to optimize thermal efficiency)
-
Finned Section Length: 9,000 mm (9 meters of continuous, flawless welding)
Using our advanced automated High-Frequency Welding (HFW) technology, the spiral fin tape was fused to the 159 mm GOST pipe with a 98% minimum weld fusion rate. This ensures zero thermal resistance gaps, preventing fin detachment or thermal decay even under continuous high-temperature gas boiler operations.

The Results & Customer Feedback
Currently, this shipment of heat exchange equipment—carrying trust and anticipation—has been successfully dispatched.The Kazakhstani client was highly impressed by Datang’s fast production turnaround, strict compliance with GOST standards, and the sheer structural integrity of the 11–12 mm heavy-wall tubes.
Since installation, the gas boiler heat exchanger has achieved optimal thermal efficiency, significantly lowering flue gas exhaust temperatures and reducing operational energy costs for the end-user.
-
18% Boost in Heat Recovery Efficiency: Thanks to the perfect contact bond of Datang’s HFW finned tubes, the exhaust gas waste heat recovery rate skyrocketed. The plant successfully reclaimed more energy from the flue gas, lowering the final exhaust temperature while maximizing the district heating loop’s output.
-
Substantial Fuel Savings & Rapid ROI: By capturing more heat from the same volume of natural gas, the utility plant significantly reduced its fuel consumption, achieving a rapid return on investment.
