Qhov yuav tsum tau muaj rau Butt Vuam Flange Manufacturing
Jun 15, 2022
Vuam flanges feem ntau yog tsim los ntawm forging los yog forging thiab dov. Thaum siv cov phaj steel lossis ntu steel, yuav tsum tau ua raws li cov cai hauv qab no:
1. Butt-welded flanges yuav tsum tau kuaj ultrasonically, thiab yuav tsum tsis muaj delamination defects;
2. Nws yuav tsum tau txiav mus rau hauv ib daim hlab raws lub dov kev taw qhia ntawm cov hlau, thiab ces yuav tsum tau khoov thiab pob tw welded rau hauv ib lub nplhaib, thiab cov nto ntawm cov hlau yuav tsum tau tsim nyob rau hauv ib tug cylindrical nto ntawm lub nplhaib. Cov hlau phaj yuav tsum tsis txhob ncaj qha mus rau hauv lub taub qab-welded flange nrog caj dab;
3. Lub pob tw weld ntawm lub nplhaib yuav tsum tau txais kev nkag mus rau tag nrho;
4. Lub pob tw weld ntawm lub nplhaib yuav tsum raug kho tom qab vuam kub thiab 100 feem pua ntawm radiographic los yog ultrasonic soj ntsuam. Kev tshuaj xyuas hluav taws xob ua tau raws li qhov yuav tsum tau ua ntawm Chav Kawm II ntawm JB4730 thiab kev tshuaj xyuas ultrasonic ua tau raws li qhov yuav tsum tau ua ntawm Chav Kawm I ntawm JB4730.
