High Efficient Seamless Boiler Header Manifold For Heat Exchange Boiler

High Efficient Seamless Boiler Header Manifold For Heat Exchange Boiler

Product Description of Header

The main function is to collect the working materials or redistribute the working materials to other pipelines through the collecting box, that is, to collect and mix the working materials, to ensure the uniform distribution of working materials and even distribution of the working materials.

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.

Material	Carbon steel,Alloy steel,Stainless steel.
Length	According to costumes requirements.
Temperature Range	300℃~1500℃
Diameter(OD)	76mm~914mm

Function of Header

The collecting box is the pipe fitting for boiler working medium mixing and ensuring uniform heating of working medium.Industrial boiler furnace wall is usually composed of rows and rows of tubes (water wall) together, but boiler huge volume, complicated structure, cannot guarantee that all the working medium in the pipe of heat absorption capacity is the same, different parts of heat absorption differs a lot, install header can let each pipe working medium inside converge here, the redistribution to the next level in the tube, so that we can reduce the thermal deviation, make the working medium heat, cooling flow, boiler, the boiler thermal efficiency are optimized to improve;In addition, the size, quantity and arrangement of pipes in the upper, middle and lower parts of the boiler are different, and the collecting box is responsible for connecting each section to ensure the smooth flow of working quality.

Features of Header

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 of Header

1.Our products are manufactured by way of hot pressing and seamless steel tube retraction on special back neck machine.

2.In this way, obstacles will have thicker walls and cleaner surfaces.The film stress instead of bending stress is formed under the action of internal pressure, which has ideal stress performance.

Classification of Header

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.

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.
