Ukuphikelela kokuthi “Ikhwalithi ephezulu, Ukulethwa Okusheshayo, Intengo Enolaka”, sisungule ukubambisana kwesikhathi eside namakhasimende avela phesheya kwezilwandle nasekhaya futhi sithola ukuphawula okuphezulu kwamakhasimende amasha namadala Ngesithunzi Esiphezulu se-DIN1629 St37 St44 St52 S355j2h Seamless Carbon Steel Pipe, Sikumema nobabili wena nebhizinisi lakho ukuthi niphumelele kanye nathi futhi nihlanganyele isikhathi eside esinempilo emkhakheni womhlaba.
Ukuphikelela kokuthi “Ikhwalithi ephezulu, Ukulethwa Okusheshayo, Intengo Eyingozi”, sisungule ukubambisana kwesikhathi eside namakhasimende avela phesheya kwezilwandle nasekhaya futhi sithola ukuphawula okuphezulu kwamakhasimende amasha namadalaAmapayipi Angenamthungo kanye Nepayipi Lensimbi, Sihlose ukuba ibhizinisi lesimanje elinomqondo omuhle wezohwebo “wobuqotho nokuzethemba” futhi ngenhloso “Yokunikeza amakhasimende amasevisi aqotho kakhulu nemikhiqizo yekhwalithi engcono kakhulu”.Sikucela ngobuqotho ukwesekwa kwakho okungaguquki futhi sibonga izeluleko nesiqondiso sakho esinomusa.
Ipayipi eli-odwe ngaphansi kwalokhu kucaciswa lisetshenziselwa isevisi yokucindezela okuphezulu emazingeni okushisa asemoyeni naphansi.Isetshenziswa kakhulu ekudluliseni uwoyela negesi yemvelo.
I-ASTM A671I-LSAW(JCOE) Ipayipi Lensimbi Yekhabhoniizoba ngama-welded kabili, ama-welds angena ngokugcwele enziwe ngokuhambisana nezinqubo futhi ngabashiseli 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 okushisa 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 Kwengcindezi—Izici eziqinile eziguquguqukayo zelunga elishiselwe zizohlangabezana nezidingo ezincane zamandla okugcina aqinile wento yepuleti elishiwo.
Ukuhlola okugobile okuqondiswa-okuguquguqukayo—Isivivinyo sokugoba siyokwamukeleka 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 Kwezithombe Zomsakazo-Ubude obugcwele be-weld ngayinye yekilasi X1 ne-X2 buzohlolwa ngokwemisakazo ngokuhambisana futhi kuhlangatshezwane nezimfuneko ze-ASME Boiler and Pressure Vessel Code, Isigaba sesikhombisa, isigaba UW-51.
