Factory Direct ISO Certificate Header for Boiler
The boiler headers 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.
The critical point to manufacture the end cover 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 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.
Material
The header is consisted of header body ( large diameter seamless steel tube ), end cover ( enclosure ) , tube joint, hand hole, thermomter socket and so on. And the welding checking is strictly proceeded as the welding process to guarantee 100% qualified products.
