Wide Range Radius Economiser In Thermal Power Plant , High Efficiency Economizer For Boiler
Product Description
The technology of H-fin tube economizer is a high-efficiency heat transfer economizer assembled by H-fin tube (also known as H-fin tube, rib tube and butterfly tube).The basic form is "H" type and double "H" type, arranged in sequence.
Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient H-fin tubes.HD BOILER has also completed stand-alone product quality assurance systems.Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.
Introduction
| 1 | HDB equipment can bend tubes and pipes up to approximately28 meters long. |
| 2 | This equipment can bend up to 90 degrees on each end with extreme accuracy and repeat-ability. |
| 3 | In addition we have 2 Pines benders (with added hydraulic boost systems) which are known throughout the industry for accuracy and the ability to perform the most difficult, tight radius bends and produce high quality results. |
| 4 | Our knowledgeable staff can focus years of experience on finding solutions to your tube and pipe bending needs. |
Features
| 1 | We offer bending for HRSG tubes, boiler tubes, economizer tubes, super-heater tubes, 180 degree return bends, 90 degree , replacement tubes both bare and finned for boiler repair and more. |
| 2 | Our capabilities cover a broad range of materials including, but not limited to, carbon steel, alloy steel,stainless steel in its various grades. |
| 3 | We are able to verify wall thickness of the bends we produce using both destructive and ultrasonic testing giving you assurance of receiving the product and quality you expect. |

| 7 | Inspectors monitor and record these measurements during production. |
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. |
