Loj-inch LSAW steel yeeb nkab ntau lawm txheej txheem piav qhia:
1. phaj sojntsuam: siv los tsim cov kab loj loj submerged arc welded steel yeeb nkab pob qij txha ncaj tom qab nkag mus rau hauv cov kab ntau lawm, thawj qhov kev ntsuam xyuas tag nrho ntawm ultrasonic;

2. Milling: milling tshuab los ntawm ob sab ntug ntawm lub phaj milling, thiaj li ua tau raws li qhov yuav tsum tau ntawm lub phaj dav, lub phaj sab sib npaug mus rau qhov zawj puab thiab qib;

3. Pre-curved sab: kev siv lub tshuab ua ntej khoov ua ntej khoov phaj ntug, ntug ntawm lub phaj yuav tsum tau ua raws li qhov yuav tsum tau ua ntawm curvature;

4. Kev sib sau: hauv thawj ib nrab ntawm JCO molding tshuab tom qab lub kauj ruam ua ntej khoov tom qab ob peb lub thwj steel, nias rau hauv "J" zoo, thiab tom qab ntawd ib nrab ntawm tib lub phaj steel khoov, nias rau hauv "C" duab , tsim qhov kawg qhib Qhov "O"-puab

5. Pre-welding: ua ib tug ncaj seam welded steel yeeb nkab tom qab tsim thiab siv roj welding seam (MAG) rau nruam vuam;

6. Sab hauv weld: ib tandem multi-wire submerged arc vuam (txog plaub hlau) nyob rau hauv ncaj seam welded steel yeeb nkab;

7. Sab nraud weld: ib tandem multi-wire submerged arc vuam rau sab nraud LSAW steel yeeb nkab vuam;

8. Ultrasonic kuaj: sab hauv thiab sab nraud ntawm qhov ncaj seam welded steel yeeb nkab weld thiab vuam ob sab ntawm cov khoom siv hauv paus 100% tshuaj xyuas;

9. X-ray tshuaj xyuas: 100% weld nyob rau sab hauv thiab sab nraud ntawm X-ray industrial TV tshuaj xyuas siv cov duab ua haujlwm kom paub tseeb tias qhov rhiab heev;

10. Kev nthuav dav: Rau submerged arc vuam thiab ncaj seam steel yeeb nkab ntev lub qhov taub txhawm rau txhawm rau txhim kho qhov loj precision ntawm steel raj, thiab txhim kho kev faib tawm ntawm kev ntxhov siab hauv steel raj;

11. Hydraulic xeem: Nyob rau hauv lub hydraulic xeem tshuab rau steel tom qab expanding by-root test los xyuas kom meej tias cov steel yeeb nkab los ntsuam xyuas lub siab xav tau ntawm tus qauv, lub tshuab muaj ib tug tsis siv neeg kaw lus thiab cia muaj peev xwm;

12. Chamfering: cov yeeb nkab steel tshuaj xyuas tom qab qhov kawg ntawm kev ua rau cov yeeb nkab kawg beveling qhov yuav tsum tau muaj.
