Manje sinethimba elinekhono, elisebenza kahle elihlinzeka ngezinsizakalo zekhwalithi enhle kubathengi bethu.Sivamise ukulandela inkambiso yokuthambekela kumakhasimende, egxile kumininingwaneIpayipi lensimbi laseChina LSAW/SSAW kanye nepayipi elishiselwe, Umgomo wethu ukuletha inani eliphakeme ngokungaguquki kumakhasimende ethu nakumakhasimende awo.Lokhu kuzibophezela kuthinta yonke into esiyenzayo, kusishukumisela ukuthi siqhubeke sithuthukisa futhi sithuthukise izixazululo zethu kanye nezinqubo zokufeza izidingo zakho.
Ipayipi eli-odwe ngaphansi kwalokhu kucaciswa lisetshenziselwa isevisi yokucindezela okuphezulu emazingeni okushisa asemoyeni naphansi.Ikakhulukazi isetshenziselwa ukudluliswa kukawoyela negesi yemvelo.
I-ASTM A671 LSAW(JCOE) Ipayipi Lensimbi Lekhabhoni lizoba amashisela ashiselwe kabili, angena ngokugcwele enziwe ngokuvumelana nezinqubo nangama-welder noma ama-welding operator afaneleka ngokuhambisana ne-ASME Boiler kanye ne-pressure Vessel Code, Isigaba IX.
Wonke amakilasi ngaphandle kuka-10, 11, 12 kanye no-13 azophathwa ukushisa esithandweni esilawulwa ku-±15℃ futhi afakwe i-hydrometer yokurekhoda ukuze amarekhodi okushisisa atholakale.

1. Ububanzi Bangaphandle-Kusekelwe esilinganisweni esiyindilinga ±0.5% sobubanzi obushiwo bangaphandle.
2. Ngaphandle Kwe-Roundness-Umehluko phakathi kwamadayamitha angaphandle amakhulu namancane.
3. Ukuqondanisa-Kusebenzisa i-10 ft (3m) yokuqondisa ebekwe ukuze iziphetho zombili zithintane nepayipi, 1/8 in. (3mm).
4. Ukuqina-Ubukhulu obuncane bodonga kunoma iyiphi indawo epayipini akumele bube ngaphezu kuka-0.01 in. (0.3mm) ngaphansi kogqinsi olushiwo.
5. Ubude obuneziphetho ezingashintshiwe buyoba phakathi kuka--0+1/2 in. (-0+13mm) walokho okushiwo.Ubude obuneziphetho ezenziwe ngomshini buzoba njengokuvunyelwana ngabo phakathi komkhiqizi nomthengi.
Ukuhlolwa Kokuqina—Izici eziqinile eziguquguqukayo zelunga elishiselwe zizohlangabezana nezidingo ezincane zamandla okugcina aqinile wento yepuleti elishiwo.
Ukuhlola okugobile okuqondiswa-okuqondiswa-okuguquguqukayo—Ukuhlolwa kokugoba kuyokwamukeleka uma kungekho mifantu noma okunye ukukhubazeka okudlula u-1/8 in. (3mm) kunoma iyiphi indlela ekhona ensimbi yokushisela noma phakathi kokushisela nesisekelo sensimbi ngemva kokugoba.
Ukuhlolwa kwe-Radio-graphic-Ubude obugcwele be-weld ngayinye yekilasi X1 ne-X2 buzohlolwa nge-radiographic ngokuhambisana futhi kuhlangatshezwane nezimfuneko ze-ASME Boiler and Pressure Vessel Code, Isigaba sesikhombisa, isigaba UW-51.
