A Trust That Crosses Borders, Built on Datang’s Precision Engineering
Project Overview
Datang Finned Tube recently completed the production and delivery of a specialized batch of G-Type (Embedded) finned tubes for a prominent client in Jordan. The tubes are designed for large-scale air-cooled heat exchangers, where high thermal efficiency and mechanical stability are paramount.
For this Jordan project, Datang Finned Tube adhered to stringent technical requirements to ensure long-term performance in desert environments:
-
Base Tube Material: We utilized SA179 Killed Low Carbon Steel (Seamless) to provide maximum structural integrity.
-
Precision Geometry: The tubes feature a 25.4 mm OD and a length of 12,500 mm, with a guaranteed minimum wall thickness under the fin of 2.11 mm.
-
Fin Configuration: High-grade Aluminum SB209 Grade 1100-O fins were applied using the G-Type (Embedded) method, with a precise density of 433 fins per meter.
-
Quality Assurance: Datang Finned Tube coordinated a mandatory Third-Party Inspection (TPI) for final dimensional checks and leak testing prior to dispatch.
-
Weatherproof Packaging: To safeguard the 57.15 mm OD fins, the tubes were secured in fully enclosed, weatherproof wooden boxes designed by the Datang Finned Tube logistics team.
Quality Control & Process Transparency
1. Core Craftsmanship: Why Choose Datang’s G-Type Embedded Tubes?
- Extremely High Mechanical Strength: The fins are not easily deformed and can withstand high-pressure washing and harsh working conditions.
- Superior Corrosion Resistance: The tight embedded structure minimizes the risk of crevice corrosion, resulting in a longer service life.
Embedded Fin Tube Measurement

As shown in the image above, our technical team is double-checking critical dimensions of the finished products. The challenge in manufacturing G-type finned tubes lies in ensuring a tight fit between the fins and the base tube; even a microscopic gap could affect heat transfer efficiency. Through high-precision measuring tools, Datang Finned Tube ensured that the contact thermal resistance was minimized, fully meeting the design requirements for heat exchange.
2. Professional Export Packaging (Crating)
To ensure the delicate aluminum fins remain undamaged during international transit, we implemented a robust packaging strategy:
Structural Support: Custom wooden separators between layers to prevent crushing.
Anti-Corrosion: Moisture-proof lining to protect the tubes from humid sea air.
Reinforced Crates: Heavy-duty plywood boxes designed to withstand multiple crane lifts and container handling.
Embedded Finned Tube Packaging

This rigorous packaging method is part of Datang Finned Tube’s promise to our clients—not only do we manufacture excellent tubes, but we also ensure they arrive in perfect condition.
3. Seamless Shipping & Logistics
The cargo has been successfully loaded and is currently en route to Jordan. Our logistics team provides real-time updates, ensuring the client has full visibility of their order from our factory in Yanshan to the port of arrival.

Why G-Type Finned Tubes?
Embedded (G-type) finned tubes are preferred for high-temperature applications (up to 400°C). Since the fin is mechanically locked into a groove, it maintains excellent thermal contact even under significant thermal cycling and vibration.
Why Do Global Clients Trust Datang Finned Tube Solutions?
