BOILER COMPONENTS
Headers

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. 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 header.
Beveling 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.
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.
