JKKP Knowledge Sharing Session for Officers

We are pleased to share that our Executive Director, Mr. James Bae, was invited as a guest speaker by Department of Occupational Safety and Health (JKKP/DOSH) Johor to deliver a training session on the Fundamentals of Boiler & Pressure Vessel Inspection. The session aimed to enhance technical competency through the exchange of engineering knowledge, industry best practices, and practical insights into boiler and pressure vessel inspection.

We were especially honored to have our Executive Director, Mr. James Bae, serve as the guest speaker for the training. Design of Boiler and Pressure Vessels on his extensive engineering and industry experience, Mr. Bae shared practical knowledge and international best practices, fostering engaging discussions with the participating JKKP officers.

The session reflects HFS’s ongoing commitment to supporting professional development, strengthening industry–government collaboration, and promoting higher standards of industrial safety and engineering excellence in Malaysia.

Advantage of High Frequency Welded(HFW) Finned Tube vs Embedded Fin (G type) & Extrude Type
Weldability	High Frequency Welded (HFW) can be applied dissimilar tube and fin welds instead of G-Type and Extrude Type
Efficiency	Higher heat exchange efficiency, 10% higher than G-Type, 15% higher than Extruded
Cost Save for Material	Tube material cost saving, 10% for G-type (0.3mm Groove), Much less for Extruded Type
Flexible Fin Pitch	Smaller and lighter equipment
Tube Size and Quantity	Minimum 10% reduce tube size and quantity
Higher Temperature	Applied to higher temperature depend on design temperature
Strong Durability & Maintenance	Strong durability with welded fin, Easy handling and waterjet washed.
