Ukusetshenziswa Kwepayipi Elishiselwe I-Longitudinal Submerged-arc:

Icala lobunjiniyela laseHong Kong

Icala lobunjiniyela laseQatar

Icala lobunjiniyela laseTurkey

Inqubo Yokukhiqiza Yepayipi Elishiselwe I-Longitudinal Submerged-arc:

I-Longitudinal Submerged-arc Eshiselwe(LSAW) Ipayipi isebenzisa 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 ye-arc eshiselwe ipayipi lensimbi eqondile ihlanganisa 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

Ubude obuncane obuyisisekelo bokujiya kodonga lwezibizo %6 in. (7.9 mm) noma ngaphezulu: Ubude ngamayintshi angu-8. (203.2 mm), amaminithi, % Ukwelulwa kokungu-2 in. (50.8 mm), min, %	18 30	14 25	... 20
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 kweMechanical kanye ne-NDT yeI-API 5L PSL1&PSL2Ipayipi Elishiselwe Longitudinal Submergerd-arc

Inani eliphansi le-ASTM inqwaba yamapayipi ensimbi angama-252

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 i-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

UkupakishaIpayipi Elishiselwe I-Longitudinal Submerged-arc

Ipayipi elingenalutho, ukugqoka okumnyama (okwenziwe ngokwezifiso);
Zombili ziphela ngabavikeli bokugcina;
Ukuphela okungenalutho, ukuphela kwe-bevel;
Ukumaka.

Umkhiqizi wepayipi lensimbi yeCarbon LSAW

Ukubekezelela ububanzi bangaphandle, ukushuba kodonga, ubude nesisindo:

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 zizonikezwa 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 angeke sihluke ngaphezu kuka-15% ngaphezulu noma u-5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo nesisindo salo ngobude beyunithi ngayinye.
