Power Station Boiler Manifold Headers , Steam Boiler Header Piping ASME Standrd
Power Station Boiler Header Heating Power Chemical Oil Chemical Industry boiler unit SGS
Product Description
The boiler headers have water wall header, superheater header, economizer header and so on, it acts as collection, mixture, re-distributing working medium. From the structure, it can be classified as the end cover type (end closure) 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 size device and mature technology. Especially the welding of the end cover with the header, we adopt the auto submerged welding, this welding method is featured with high manufacturing efficiency, good quality, artistic appearance and safe and reliable operation.
