Product Description
The steam boiler pressure part header with large diameter
longitudinal welded pipe have water wall header, superheater
header, economizer header and so on, it acts as collection,
mixture, re-distributing working medium, as the structure, it can
be classified as the end cover type( end enclosure) and necking
down type.
Technical parameters of customer design boiler pressure parts header for CFB boiler
Technical parameters of customer design boiler pressure parts header for CFB boiler
| 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. |
Details
Diameter(OD) | ¢76mm~¢914mm |
Length(Max) | 23000mm |
Temperature(℃) | 300~1500 |
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.
Classification
In bringing a boiler on the line with other boilers on a header
system,certain precautionss are necessary to avoid water hammer and
excessive temperature gradients in the piping. Adequate drainage
and warming of the piping will eliminate the risk of water hammer.
The judicious use of bypass valves around main header valves will
avoid steep temperature gradients. Header drains should be
operated. The steam line from the boiler to the header should be
brought up to temperature by operating bypass and drain valves.
When up to temperature and line pressure, the header valve may be
opened wide and the bypass closed.

Application
Steam distribution headers are fabricated out of carbon steel or alloy steel seamless tubes. Customized or tailor made items are offered. Headers, after fabrication, are stress relieved to make the Steam distribution headers free from stresses. They are big pipe headers that transfer water from the downcomers to the risers through a combustion zone where the water gets partially heated to steam from the heat of fuel combustion.
