2, Ceev faj:
A. Cov phab ntsa tuab ntawm cov yeeb nkab steel tsis txaus. Siv cov cuab yeej sprue, lub qhov ncauj qhov kawg ntawm cov yeeb nkab steel zoo li tuab nrog rauj shroud, tab sis cov duab qub tau tshwm sim los ntawm kev ntsuas ntsuas.
B. Siv ncaj seam li seamless steel yeeb nkab. Tus naj npawb ntawm cov seam welds yog tsawg dua li cov longitudinal seam welds. Cov yeeb nkab steel yog polished los ntawm lub tshuab, feem ntau hu ua polishing. Nws zoo li seamless yam tsis muaj seams.
C. Tam sim no muaj ntau txoj hauv kev ntawm seamless steel yeeb nkab, uas tseem hu ua kub nthuav dav hlau yeeb nkab. Thaum nthuav dav, nws muaj hmoov txhuas hauv thiab hlawv cov cim rau sab nraud. Cov welds zoo li tsis pom. Ntau cov kav hlau loj dua tau siv los muag cov yeeb nkab no seamlessly rau cov txiaj ntsig ntau dua.
D. Ntiv nplhaib seam steel yeeb nkab siv polishing los sawv cev seamless thiab ncaj seam steel yeeb nkab.
