Industrial high quality boiler part headers with best price 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. Industrial high quality boiler part headers with best price collect and distribute steam or water from or to a serious of smaller pipes or conduits. They are made of carbon or ferritic steel, generally of the same grade as the piping system.

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.
