Water Tube Naturally Circulated Steam Boiler Headers with High Pressure for Industry
Product Introduction
The boiler is composed of a part that contains water to generate steam and a furnace that burns heat energy. In order to transfer the burning heat energy to the water in the boiler, the boiler must have enough heat transfer area. In order to expand the heat transfer area, the cylindrical boiler is developed into a tubular boiler to increase the heat transfer area.
Features
1. Strength calculation report with applied materials information.
2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod.
3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler.
4. Hydraulic test report: ensure the standard working pressure and safety.
5.Excellent in welding quality, highly automatic, safe and reliable.
Material
1. Carbon steel:20G,SA-106B,SA-106C,etc.
2. Low-alloy thermal resistant steel:15CrMoG,12Cr1MoVG,SA-335P12,SA335-P22,etc.
3. Middle-alloy thermal resistant steel:SA-335P91,etc.
4. Special material(ultra-supercritical):SA-335P122,SA-335P92,etc.
The boiler headers have water wall header,superheater header,economizer header and so on. It acts action of gathering, mixing and redistribution in boiler systems. In structure, they include end cover hinders or necking hinders.
Working Principle
The water in these bundles must be continuously circulated to absorb heat and separate the steam, which is concentrated in the upper part of the box (barrel), and the water from the lower part into the lower box (barrel), and distributed among the root bundles to continue to absorb the heat in the furnace.
We call the upper and lower assembly boxes (barrels) boiler header.
| 1 | Headers form an important part of all types of boilers. |
| 2 | Steam from the generating tubes is collected in headers which are therefore always under pressure. |
| 3 | This pressure may vary from 300 psi to 2000 psi. Since headers are always under pressure, the utmost care is taken by us while fabricating them. |
| 4 | Depending on the generating capacity of the boiler the header sizes fabricated by us vary from 100 mm to 600 mm NB. The stubs of various sizes are very carefully welded to the main body of the header to provide the desired openings from the header. |
Parameters
| Diameter(OD) | ¢76mm~¢914mm |
