Coal Fired CFB Hot Water Boiler Manifold Headers Pipes For Water / Steam Transfer

Product Description

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.

Process

The critical point to manufacture the end cover of steam trap boiler economizer header is the welding process. We adopt the advanced manufacture process, the complete large sized device and mature technology, especially the welding of the end cover with the boiler part header, we adopt the auto submerged welding, this welding method exists the high manufacture efficiency, good quality, the artistic welding appearance, safe and reliable operation.
