Ukusetyenziswa kwe-Longitudinal Submerged-arcUmbhobho odityanisiweyo:

Imeko yobunjineli yaseHong Kong

Imeko yobunjineli baseQatar

Imeko yobunjineli yaseTurkey

Inkqubo yokuVelisa iLongitudinal Submerged-arc eWelded Pipe:

Umbhobho we-LSAWYamkela itekhnoloji ye-arc yokuntywila emanzini, isebenzisa i-filler welding, i-particle yokukhusela i-flux engcwatywe i-arc.

I-LSAW sisishunqulelo sesiNgesi se-arc entywiliselweyo edityanisiweyo yentsimbi yomthungo ethe ngqo.Inkqubo yemveliso ye-arc edityanisiweyo yentsimbi yomthungo ethe tye ibandakanya iteknoloji yokwenza i-JCOE, i-coil eyenza iteknoloji ye-arc welding ephantsi kunye ne-UOE yokwenza iteknoloji.

Inkqubo yokwenziwa koMbhobho weLongitudinal Submerged-arc Welded(LSAW) imi ngolu hlobo lulandelayo:

Ukuhlolwa kwepleyiti ye-Ultrasonic → i-edge milling → ukugoba kwangaphambili → ukwenza → ukuwelda kwangaphambili → i-welding yangaphakathi→ i-welding yangaphandle → Ukuhlolwa kwe-ultrasonic → Ukuhlolwa kwe-X-reyi → Ukwandisa → uvavanyo lwe-hydraulic →l.I-Chamfering → Ukuhlolwa kwe-Ultrasonic → Uhlolo lwe-X-reyi → uhlolo lwesuntswana lamagnetic ekupheleni kwetyhubhu

Iimvavanyo zoomatshini kunye ne-NDT ye-API 5L PSL1&PSL2Longitudinal Submergerd-arc Welded uMbhobho

Uvavanyo lweHydrostatic

Uvavanyo lwe-NDT (RT).

I-Longitudinal Arc Seam kunye neMibhobho

Uvavanyo lwe-NDT (UT).

Ukugoba uvavanyo-ubude obaneleyo bombhobho buya kuma bugobe bubanda nge-90 ° malunga ne-cylindrical mandrel.

Uvavanyo lokucaba-Nangona uvavanyo lungafuneki, umbhobho uya kuba nakho ukuhlangabezana neemfuno zovavanyo lokuthambisa.

Uvavanyo lwe-Hydrostatic-ngaphandle kokuba kuvunyelwe, ubude bombhobho ngamnye buya kufakwa kuvavanyo lwe-hydro-static ngaphandle kokuvuza ngodonga lombhobho.

Uvavanyo lombane olungonakaliyo-njengenye indlela yovavanyo lwe-hydro-static, umzimba opheleleyo wombhobho ngamnye uya kuvavanywa ngovavanyo lombane olungonakaliyo.apho uvavanyo lombane olungonakalisiyo lwenziwayo, ubude buya kuphawulwa ngoonobumba”NDE”

Uvavanyo lwe-ultrasonic

Uviwo lwangoku lwe-eddy

Ukupakisha i-Longitudinal Submerged-arcUmbhobho odityanisiweyo

Umbhobho ongenanto, iingubo ezimnyama (ezilungiselelwe);
Zombini ziphela kunye nabakhuseli bokugqibela;
Isiphelo esicacileyo, i-bevel end;
Ukumakisha.

Ndabona ababoneleli bemibhobho yentsimbi

API 5L Carbon LSAW umenzi wentsimbi yombhobho

Ukunyamezela ububanzi bangaphandle, ubukhulu bodonga, ubude kunye nobunzima:

Ngaphandle Ububanzi	Idayamitha yangaphandle yeemfumba zemibhobho ayinakwahluka ngaphezu kwe-±1% ukusuka kwidayamitha yangaphandle echaziweyo.
Ubunzima bodonga	Ubunzima bodonga nakweyiphi na indawo abuyi kuba ngaphezu kwe-12.5% phantsi kobukhulu obuchaziweyo bodonga.
Ubude	Iimfumba zemibhobho ziya kunikezelwa ngobude obungakhethiyo obubodwa, ubude obuphindwe kabini, okanye ubude obufanayo njengoko kuchaziwe kumyalelo wokuthenga, ngokuhambelana nemida ilandelayo:	Single random ubude	16 ukuba 25ft (4.88 ukuba 7.62mm), intshi
		kabini ubude random	Ngaphezulu kwe-25ft (7.62m) kunye nomyinge omncinci we-35ft (10.67m)
		Ubude obufanayo	ubude njengoko kucacisiwe ngotshintsho oluvumelekileyo lwe ±1 ngo.
Ubunzima	Ubude bengqumba yombhobho nganye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bayo abuyi kwahluka ngaphezu kwe-15% ngaphezulu okanye i-5% phantsi kobunzima bayo bethiyori, ibalwe kusetyenziswa ubude bayo kunye nobunzima bayo ngeyunithi yobude.
