Ipayipi le-LSAWyamukela ubuchwepheshe bokushisela be-arc obungaphansi kwamanzi, isebenzisa i-filler welding, i-particle protection flux engcwatshwe i-arc.
I-LSAW isifinyezo sesiNgisi sepayipi lensimbi elingaphansi kwamanzi elishiselwe umthungo oqondile.Inqubo yokukhiqiza ipayipi lensimbi elingene ngaphansi kwe-arc elishiselwe umthungo oqondile lihlanganisa ubuchwepheshe bokwenza i-JCOE, ubuchwepheshe bokushisela be-arc obungaphansi kwamanzi kanye nobuchwepheshe bokwenza i-UOE.
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

Ngobukhulu obuncane bodonga obungaphansi kuka-%6 in. (7.9 mm), imali ebanjwayo kusukela kubude obuncane obuyisisekelo ngamayintshi angu-2 (50.08 mm) ku-Vzi ngayinye - ngo. (7.9 mm), ngamaphesenti amaphuzu | 1.5A | 1.25A | 1.0A... |
Ukuhlolwa kwe-Hydrostatic
Ukuhlolwa kwe-NDT(RT).
Ukuhlolwa kwe-NDT(UT).
Ukuhlola Ukugoba—ubude obanele bepayipi buzoma bugotshwa bubanda ngo-90° buzungeze i-cylindrical mandrel.
Ukuhlolwa kokucaba-nakuba ukuhlolwa kungadingeki, ipayipi lizokwazi ukuhlangabezana nezidingo zokuhlola eziphansi.
Ukuhlolwa kwe-Hydrostatic-ngaphandle uma kuvunyelwe, ubude bepayipi ngalinye buzohlolwa nge-hydro-static ngaphandle kokuvuza odongeni lwamapayipi.
Ukuhlolwa kukagesi okungonakali-njengenye indlela yokuhlola i-hydro-static, umzimba ogcwele wepayipi ngalinye uzohlolwa ngokuhlolwa kukagesi okungangonakali.lapho kuhlolwa khona ugesi ongonakali, ubude buzomakwa ngezinhlamvu”NDE”
Ukuhlolwa kwe-ultrasonic
Ukuhlolwa kwamanje kwe-eddy
Ipayipi elingenalutho, ukugqoka okumnyama (okwenziwe ngokwezifiso);
Zombili ziphela ngabavikeli bokugcina;
I-Plain end, i-bevel end;
Ukumaka.
Ngaphandle Ububanzi | Ububanzi bangaphandle bezinqwaba zamapayipi akufanele buhluke ngaphezu kuka-±1% ukusuka kububanzi obushiwo bangaphandle. | ||
Ukujiya kodonga | Ukuqina kodonga kunoma iyiphi indawo akumele kube ngaphezu kuka-12.5% ngaphansi kogqinsi olucacisiwe lodonga. | ||
Ubude | Izinqwaba zamapayipi zizohlinzekwa ngobude obungahleliwe obubodwa, ubude obuphindwe kabili obungahleliwe, noma ubude obufanayo njengoba kucacisiwe ku-oda lokuthenga, ngokuvumelana nemikhawulo elandelayo: | Ubude obubodwa obungahleliwe | 16 kuya ku-25ft (4.88 kuya ku-7.62mm), intshi |
Ubude obuphindwe kabili obungahleliwe | Ngaphezulu kuka-25ft (7.62m) nobuncane besilinganiso esingu-35ft (10.67m) | ||
Ubude obufanayo | ubude njengoba kucacisiwe ngokuhluka okuvumelekile okungu-±1 in. | ||
Isisindo | Ubude benqwaba yamapayipi ngayinye buzokalwa ngokuhlukana futhi isisindo sawo akumele sihluke ngaphezu kuka-15% ngaphezulu noma u-5% ngaphansi kwesisindo saso esicatshangelwayo, kubalwe kusetshenziswa ubude baso nesisindo saso ngobude beyunithi ngayinye. |
