Product Description The steam boiler pressure part header with large diameter
longitudinal welded pipe have water wall header, superheater
header, economizer header and so on, it acts as collection,
mixture, re-distributing working medium, as the structure, it can
be classified as the end cover type( end enclosure) and necking
down type. Technical parameters of customer design boiler pressure parts header for CFB boiler

Features
1. Strength calculation report with applied materials information. 5.Excellent in welding quality, highly automatic, safe and reliable.
Classification In bringing a boiler on the line with other boilers on a header
system,certain precautionss are necessary to avoid water hammer and
excessive temperature gradients in the piping. Adequate drainage
and warming of the piping will eliminate the risk of water hammer.
The judicious use of bypass valves around main header valves will
avoid steep temperature gradients. Header drains should be
operated. The steam line from the boiler to the header should be
brought up to temperature by operating bypass and drain valves.
When up to temperature and line pressure, the header valve may be
opened wide and the bypass closed. Parameters
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.
