Power Plant Boiler Manifold Headers High Efficient With Customized Color

Carbon Steel Power Plant Boiler Manifold Headers High Efficient Energy Saving
Product Description

Headers collect and distribute steam or water from or to a series of smaller pipes or conduits. They are made of carbon or ferritic steel, generally of the same grade as the piping systems. Unlike piping systems which are usually butt welded and bent, headers are straight.

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.

In manufacturing, the key of end cover hinder is welding. Since by manual arc welding, the weld joint is single-side welding without quality guarantee at the ends. In addition, due to large welding workload, frequent return for repair and long working period, it became the throat process of the whole hinder production.
When making hinders of the style, we adopt advanced production technique, complete large equipment and mature technology, especially automatic submerged arc welding between hinders and end covers. Such welding methods have high manufacturing efficiency, good quality, beautiful welding shape, safety, reliability, etc.
MaterialCarbon steel,Alloy steel,Stainless steel.
LengthAccording to costumes requirements.
Temperature Range300℃~1500℃
Diameter(OD)76mm~914mm


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.


Details


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.



Classification

1Headers form an important part of all types of boilers.
2Steam from the generating tubes is collected in headers which are therefore always under pressure.
3This 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.
4Depending 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.

Materials

1. Carbon steel:20G,SA-106B,SA-106C,etc.

2. Low-alloy thermal resistant steel:15CrMoG,12Cr1MoVG,SA-335P12,SA335-P22,etc.

3. Middle-alloy thermal resistant steel:SA-335P91,etc.

4. Special material(ultra-supercritical):SA-335P122,SA-335P92,etc.


The boiler headers have water wall header,superheater header,economizer header and so on. It acts action of gathering, mixing and redistribution in boiler systems. In structure, they include end cover hinders or necking hinders.
