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
