Power Plant Boiler Manifold Headers High Efficient Energy Saving Materials 1. Carbon steel:20G,SA-106B,SA-106C,etc. 2. Low-alloy thermal resistant steel:15CrMoG,12Cr1MoVG,SA-335P12,SA335-P22,etc. 3. Middle-alloy thermal resistant steel:SA-335P91,etc. 4. Special material(ultra-supercritical):SA-335P122,SA-335P92,etc.
The boiler headers have water wall header,superheater header,economizer header and so on. It acts action of gathering, mixing and redistribution in boiler systems. In structure, they include end cover hinders or necking hinders. Product Description In manufacturing, the key of end cover hinder is welding. Since by
manual arc welding, the weld joint is single-side welding without
quality guarantee at the ends. In addition, due to large welding
workload, frequent return for repair and long working period, it
became the throat process of the whole hinder production. When making hinders of the style, we adopt advanced production
technique, complete large equipment and mature technology,
especially automatic submerged arc welding between hinders and end
covers. Such welding methods have high manufacturing efficiency,
good quality, beautiful welding shape, safety, reliability, etc.
Features 1. Strength calculation report with applied materials information. 5.Excellent in welding quality, highly automatic, safe and reliable.
Details 1.The necking hinders of the Company are made by hot press and retracting of seamless steel pipes at special hinder necking machine.
2.In this way, the hinders will have thicker walls and cleaner surface. The necking cover will form membrane stress rather than bending stress with desired stress performance under the effect of inner pressure.
