OEM Design Customized Boiler Manifold Headers Industrial Spare
Boiler Parts
Product Introduce
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
Manifold headers is boiler part which can improve heat exchange efficient by increase heat surface.The water in drum flow down to the headers through boiler barrel and allocate to tubes.
Water in tubes absorb heat and then collect into upper headers follow to drum.We usually named called these upper and lower headers as manifold header.
The main function of manifold headers is gather,mix and redistribution working medium to ensure uniform allocation and heating in boiler systeam.
HDB can design and manufacture headers include water-cooling headers of boiler proper,economizer headers,superheater heaters and so on.
Product Details
| 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. |
The necking hinders of the Company are made by hot press and retracting of seamless steel pipes at special hinder necking machine.
In this way, the hinders will have thicker walls and cleaner surface. The necking cover will form membrane stress rather than bending stress with desired stress performance under the effect of inner pressure.
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.
