Q1: What makes the D-type Round Condenser Tube different from traditional round tubes?
A1: The main difference lies in its D-shape cross section, which increases the heat transfer surface and improves flow dynamics. Unlike conventional round tubes, the D-type design enhances efficiency while maintaining mechanical stability.
Q2: Which materials are recommended for seawater condenser applications?
A2: For seawater environments, titanium and copper-nickel alloys are the most recommended choices. These materials provide excellent resistance against seawater corrosion and biofouling, ensuring long service life and reliability.
Q3: How do I select the correct wall thickness and diameter for my project?
A3: The selection depends on operating pressure, medium type, and installation conditions. For high-pressure systems, thicker walls (2.0 – 3.0 mm) are preferred, while low-pressure HVAC systems can operate with thinner walls. Our engineering team can provide guidance based on your specific operating environment.
Q4: Can Sinupower Heat Transfer Tubes Changshu Ltd. provide customized solutions?
