ASME Standard Horizontal Water Tube Manifold Headers for Power Plant
What is boiler manifold headers?
Manifold header is also called header, it is not an independent component, but a component of water wall, economizer, superheater and other components, that is, water wall header, economizer header and Superheater header. The function of header collects or distributes steam and water quality, reduces the pipeline of working substance transportation and connection, and reduces the number of holes in the drum, which is conducive to improving the safety performance of the drum. The lower header of the water-cooled wall near the grate on both sides of the furnace wall prevents coking on both sides of the grate, so it is called anti-coke box.
The header is actually a thick diameter tube connected with many heating surface pipes. It is made of seamless steel pipe and welded flat heads (end caps) at both ends. There are many holes in the box to weld or expand the pipe. Both ends of the economizer tube and the superheater tube are connected to the header, and the lower end of the water wall is connected to the header. The upper end can be connected to the header, and a few pipes can be drawn from the header to the upper drum, or the upper end of the water wall tube can be directly connected to the upper drum.
What is the classification of manifold headers?
Material
Carbon steel,Alloy steel,Stainless steel.
Length
According to costumes requirements.
Temperature Range
300℃~1500℃
Diameter(OD)
76mm~914mm
What are the advantages of HDB manifold headers?
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.
