Inqubo yokukhiqiza Ipayipi Longitudinal Submerged-arc Welded(LSAW) imi kanje:
Ukuhlola ipuleti le-Ultrasonic → ukugaya onqenqemeni → ukugoba ngaphambili → ukwakha → Ukushisela kwangaphambili → Ukushisela kwangaphakathi→ Ukushisela kwangaphandle → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → Ukwandisa → ukuhlolwa kwe-hydraulic →l.I-Chamfering → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → ukuhlolwa kwezinhlayiyana kazibuthe ekupheleni kweshubhu
Ukukhiqiza: I-LSAW(JCOE) Amapayipi ensimbi
Usayizi: OD: 406 ~ 1500mm WT: 6 ~ 40mm
Ibanga: CB60, CB65, CC60, CC65, njll.
Ubude: 12M noma ubude obucacisiwe njengoba kudingeka.
Iphela: I-Plain End, Beveled End, Grooved;

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.
