Ipayipi le-LSAWisebenzisa ubuchwepheshe bokushisela i-arc engaphansi komhlaba, isebenzisa ukushisela kokugcwalisa, ukuvikela izinhlayiya i-arc efihliwe.
I-LSAW yisifinyezo sesiNgisi sepayipi lensimbi elihlanganisiwe eliqondile elihlanganisiwe elihlanganisiwe elihlanganisiwe. Inqubo yokukhiqiza ipayipi lensimbi elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe lifaka ubuchwepheshe bokwakha i-JCOE, ubuchwepheshe bokwakha i-coil obuhlanganisa i-arc welding ehlanganisiwe kanye nobuchwepheshe bokwakha i-UOE.
Inqubo yokukhiqiza i-Longitudinal Submerged-arc Welded (LSAW) Pipe imi kanje:
Ukuhlola ipuleti le-Ultrasonic → ukugaya umphetho → ukugoba ngaphambi kokwenza → Ukushisela ngaphambi kokwenza → Ukushisela kwangaphakathi → Ukushisela kwangaphandle → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → Ukwandisa → ukuhlolwa kwe-hydraulic → l. Ukuxubha → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → Ukuhlolwa kwezinhlayiya ze-magnetic ekugcineni kwepayipi

Ukuhlolwa Kwamanzi
Ukuhlolwa kwe-NDT(RT)
Ukuhlolwa kwe-NDT(UT)
Ukuhlolwa Kokugoba—ubude obanele bepayipi kufanele bume bugobile bube ngama-90° buzungeze i-mandrel esilinda.
Ukuhlolwa kokuthamba-Nakuba ukuhlolwa kungadingeki, ipayipi kufanele likwazi ukuhlangabezana nezidingo zokuhlolwa kokusicaba.
Ukuhlolwa kwe-hydro-static—ngaphandle uma kuvunyelwe, ubude bepayipi ngalinye kufanele buhlolwe nge-hydro-static ngaphandle kokuvuza odongeni lwepayipi.
Ukuhlolwa kukagesi okungabhubhisi-esikhundleni sokuhlolwa kwe-hydro-static, umzimba ophelele wepayipi ngalinye kufanele uhlolwe ngokuhlolwa kukagesi okungabhubhisi. Lapho kwenziwa ukuhlolwa kukagesi okungabhubhisi, ubude buzomakwa ngohlamvu oluthi “NDE”
Ukuhlolwa kwe-ultrasound
Ukuhlolwa kwamanje kwe-eddy
Ipayipi elingenalutho, ukugqoka okumnyama (okwenziwe ngokwezifiso);
Zombili iziphetho zinezivikelo zokuphela;
Isiphetho esilula, isiphetho se-bevel;
Ukumaka.
| Ububanzi Bangaphandle | Ububanzi bangaphandle bezinqwaba zamapayipi akumele buhluke ngaphezu kuka-±1% kunobubanzi bangaphandle obubekiwe. | ||
| Ubukhulu bodonga | Ubukhulu bodonga nganoma yisiphi isikhathi akumele bube ngaphezu kuka-12.5% ngaphansi kobukhulu bodonga obubekiwe. | ||
| Ubude | Amapayipi kufanele ahlinzekwe ngobude obungahleliwe obubodwa, ubude obuphindwe kabili obungahleliwe, noma ngobude obufanayo njengoba kuchaziwe ku-oda lokuthenga, ngokuhambisana nemikhawulo elandelayo: | Ubude obungahleliwe obubodwa | 16 kuya ku-25ft (4.88 kuya ku-7.62mm), intshi |
