HP Heater(feeder water heater) is an important equipment ofpower plant regenerative system. Tube sheet, tubes, shells are the main components of HP heater. Due to its harsh working environment, the erosion and erosion of steam water can easily cause the corrosion of the burst pipe and the surfacing layer of the tube sheet. In order to solve this problem, the customer designed and developed the header(kind of Integrated tube sheet) instead of the tube sheet.The new developed component is what manufactured.
There are 6 sets of the components, We use pama130, pama160, Mitsubishi floor boring machine for synchronous processing to ensure the processing progress. The structure of the component is complex. The blank is a forging cylinder with an outer diameter of 1m, an inner diameter of 700mm and a height of 3m. More than 1900 bosses with a diameter of 25 mm are irregularly distributed on the outer surface of the workpiece. Each boss needs to be drilled through a 10 times diameter through hole, and the hole diameter accuracy and roughness have high requirements. The wall thickness between the boss and the pupil is only 4mm, and the accuracy of the wall thicknesses of each hole is less than 0.1mm. Faced with the problem that the workpiece has many bosses and irregular distribution, thin wall thickness and large machining allowance, it is easy to cause stress deformation. We use the overall small cutting amount and fast feed processing method to control the overall stress deformation problem. and purchasing custom-made tools to ensure the technical requirements of hole diameter and hole wall accuracy.
At present, we've finished two sets, The customer is very satisfied with the quality of the product through inspection and has placed an order for 8 more sets of this product.
