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 |

Test
| 1 | Latest type of 'U' bending machine is used for precision cold bending of tubes. |
| 2 | Bending is done for all kind of heat exchanger, condenser, economizer, boiler tubes in Stainless Steel Seamless as well as welded. |
| 3 | Subsequent to 'U' bending tubes are hydro tested & stress relieved if asked for. |
| 4 | Also mock-up pieces are prepared for determining thickness reduction on the bend portion. |
| 5 | Dye penetrant testing on the bend portion is done ro detect cracks, flaws or any type of defect. |
| 6 | Special packing is provided to prevent any damages during transit. |
