Product Description
The headers of boilers include water-cooling hinders of boilers proper, economizer hinders, superheater hinders, etc. They function for gathering, mixing and redistribution in boiler systems. In structure, they include end cover hinders or necking hinders.
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.


Details


1The necking hinders of the Company are made by hot press and retracting of seamless steel pipes at special hinder necking machine.
2In 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.

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.



Classification

Enamelled Corrugated Sheet Baskets are a compact arrangement of profiled metal sheets placed in the Air Preheater rotor in two or more layers and plays the most important role in the process of heat recovery.
The bottom layer, or the cold end layer, is where the air enters and the flue gases are discharged, and is therefore, subjected to severe corrosion due to acid dew point. The Material of Construction and the Profile design of the Heating Elements depends on the operating conditions, quality and type of fuel, etc.
Parameters

Diameter(OD)

¢76mm~¢914mm

Diameter(OD)

23000mm

Temperature(℃)

300~1500


Application

Steam distribution headers are fabricated out of carbon steel or alloy steel seamless tubes. Customized or tailor made items are offered. Headers, after fabrication, are stress relieved to make the Steam distribution headers free from stresses. They are big pipe headers that transfer water from the downcomers to the risers through a combustion zone where the water gets partially heated to steam from the heat of fuel combustion.
