- Product Introduction
No Contact Thermal Resistance
Our Longitudinal Finned Tube Heat Exchanger is different from the spiral type. We do not wrap fins around the tube. Instead, we machine longitudinal fins along the tube length. These fins and the tube are one piece. There is no contact thermal resistance. Our company started in 1994. We completed a shareholding system restructuring in May 2025. We have 40+ employees, including 12 senior managers. We work with China Pharmaceutical Equipment Association and China Chemical Equipment Association. Customers ask: "Do you have your own R&D team?" We say: "Yes." Our R&D team has over 30 key technical members.

Best for High-Viscosity Fluids
This product is perfect for heavy oil, asphalt, and other thick fluids. A normal smooth tube unit struggles with these fluids. They flow slowly and stick to the tube wall. But our longitudinal fins scrape the fluid. They break the boundary layer and improve heat transfer. A chemical company in Turkey uses our Longitudinal Finned Tube Heat Exchanger to heat heavy oil. It also works for industrial lubricant cooling, hydraulic oil cooling, and chemical reactor heat exchange.
Custom Orders and Repeat Business
Customers ask: "Can you produce from our drawings or prototype?" We say: "Yes. We support full non-standard customization." They ask: "Do you offer free samples?" We say: "No." But we can provide a detailed design plan based on your working conditions. Our technical team will calculate how many tubes and what layout you need. Repeat customers get faster delivery. We prioritize production for old clients. Export packing uses fumigated wooden boxes. We take photos and videos for you before shipment. We buy domestic insurance from factory to loading port. We believe our Longitudinal Finned Tube Heat Exchanger works much better than smooth tube units for thick media like heavy oil and asphalt.
