Product Description
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.

High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler
High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler Product Introduction Water wall panels with pins usually laid vertically on the inner wall of the furnace wall, it is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace.It is the main type of evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.Because of both cooling
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME Product Description The boiler economizer is a device used to recover waste heat in industrial boilers, usually located at the tail of the flue of the boiler, which increases the feed water temperature and reduces fuel consumption by absorbing the heat of the flue gas, so as to achieve the effect of energy saving and emission reduction. But at the same time, as an environmental protection equipment, the
Carbon Steel SA192 Superheater Coil Argon Arc Welding 100% PT
Product Description: A boiler superheater is an essential component in a boiler system, responsible for increasing the temperature of steam produced by the boiler.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
