|1||Headers form an important part of all types of boilers.ude end cover hinders or necking hinders.
|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.|
1.The necking hinders of the Company are made by hot press and retracting of seamless steel pipes at special hinder necking machine.
2.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.
The pressures and temperatures that headers have to withstand depend on the component to which they are connected. A header connected to an economizer or to water wall panels is subject to less severe requirements on the material than a header connected to superheaters or reheaters.
Depending on the temperature and pressure of headers, Vallourec supplies tubes in carbon steel to high-alloy ferritic steels such as T/P91 or T/P92, with sizes ranging from 88.9 mm to 406.4 mm.
|Material||Carbon steel,Alloy steel,Stainless steel.|
|Length||According to costumes requirements.|
CFB distributing economizer header with high welding technique 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.
