Product Description
DELLOK Steam to Air Gas Coolers with Longitudinal Finned Tubes
Manufacturer Profile
DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) established in 2002, operates advanced production facilities including 47 finned tube production lines with annual capacity exceeding 12 million meters. The company maintains rigorous quality control throughout all manufacturing processes.
Product Overview
Longitudinal finned tubes feature U-shaped fin channels resistance-welded along the tube's longitudinal axis, providing superior heat transfer efficiency for steam to air gas cooling applications.
Manufacturing Process
Fins are formed into U-shaped channels, cut to length, and resistance-welded in diametrically opposed pairs along the tube length. This ensures optimal heat transfer surface area based on tube diameter specifications.
Technical Advantages
Enhanced Durability
Superior working life compared to ordinary helical fin tubes with advanced welding technology.
Energy Efficiency
Optimized design reduces pressure drop and operational costs while improving heat transfer rates.
Space Optimization
Maximizes heat transfer efficiency in limited space, reducing equipment footprint requirements.
