Product process
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.
Product Description
Headers are as big pipes that transfer water from the downcomers to the risers through a combustion zone where the water gets partially heated to steam from the heat of fuel combustion.The headers of boilers include water-cooling hinders of boilers proper, economizer hinders, superheater hinders, etc. They function for gathering, mixing and redistribution in boiler systems. In structure, they include end cover hinders or necking hinders.
Test standard
JB/T3375 Boiler Material Instocking Acceptance Rules.
JB/T1610Technical Conditions of Boiler Hinders Manufacturing.
JB/T1613Technical Conditions of Boiler Pressure Parts Welding.
JB/T1612Technical Conditions of Boiler Water Pressure Test.
Product Category
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.
Construction
Header construction is basically a miniature version of a simple steam drum (diameters are smaller than the ones of steam drums). However, in headers there are usually no internals except the orifices in forced circulation and once-through principle boilers. Small diameter headers are constructed from a tube with welded front and end plates, whereas the big headers are made of bent steel plates in the same way as steam drums.
Quality Control
1. Impact test and Strength calculation report with applied materials information.
2. 100%NDT(non-destructive inspection) report of steel plate, tube and electrode.
3. X-ray, γ-ray and liquid penetrant test inspection report to ensure the quality of the entire boiler.
4. Hydraulic test report: ensure the standard working pressure and safety.
