Boiler Steam Header Brief Introduction
1. Boiler headers, or boiler manifolds are designed to simplify piping near the boiler, reduce installation time, labor costs and parts used.
2. Available in various branch options with threaded inlet and outlet connections. For closed loop heating applications only.
3. The pressures and temperatures that headers have to withstand depend on the component to which they are connected.
4. 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.
Boiler Medium Header Features
1. Headers form an important part of all types of boilers. Steam from the generating tubes is collected in headers which are therefore always under pressure. This pressure may vary from 300 psi to 2000 psi.
2. Since headers are always under pressure, the utmost care is
taken by us while fabricating them. 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 headers
3. Bevelling and weld preparation of stubs duly tack-welded to the
main body of the header are first shown to Chief Inspector of
Boilers for his approval and once again the stubs fully welded with
main body are shown to Chief Inspector of Boilers under hydraulic
pressure, varying from 1000 to 3000 psi as required by the
specifications.
4. The headers are stamped by Chief Inspector of Boilers before
they leave our manufacturing plant. We also weld skubolets and
weldolets in place of stubs.
