Boiler Superheater Coil Hot Water U Shaped Tube Eco Friendly Energy Saving
Superheater Coil Introduction
Serpentine coil is a tube that twists and turns several times in a plane.The convection heating surface of the boiler, such as economizer, superheater and reheater, adopts the structure of serpentine tube with horizontal and vertical arrangement.
| 1.Our products can be modified according to our customers' needs and the situation. 2.we design and manufacture safe,reliable and efficient products.HD BOILER has also completed stand-alone product quality assurance systems. 3.To ensure safety operation, the LT superheater uses SA210 Gr.A1 seamless steel tubes, and the HT superheater uses low-alloyed SA213 T22 seamless steel tubes. Technical parameter
Features 1. The equipment body can be designed into many modules to ensure the long term and stable running; 2. Compact structure which can enlarge the heat exchanging area in order to add the heat transfer area and less leakage 3. Improve the heat transfer efficiency 4. Structure arrangement: In line or staggered arrangement | |||||||||||
