Umbhobho we-API 5L ubhekisa kumbhobho wentsimbi yekhabhoni osetyenziswa kwiinkqubo zokuhambisa ioyile negesi. Ukwasetyenziselwa ukuthutha ezinye izinto ezinje ngomphunga, amanzi, nodaka.

Iintlobo zoMveliso

Inkcazo ye-API 5L igubungela zombini iintlobo zokwenza izinto ezidityanisiweyo nezingenamthungo.

Iintlobo ezidityanisiweyo: ERW, SAW, DSAW, LSAW, SSAW, HSAW Pipe

Iindidi eziqhelekileyo zombhobho we-API 5L welded zezi zilandelayo:

I-ERW: Ukuwelda kokumelana nombane kusetyenziswa kwipayipi enobubanzi obungaphantsi kwe-intshi ezingama-24.

DSAW/ SAW: Ukuwelda kwe-arc engaphantsi kwamanzi emacaleni amabini/ukuwelda kwe-arc engaphantsi komhlaba yenye indlela yokuwelda engasetyenziswa endaweni ye-ERW kumbhobho omkhulu.

I-LSAW: I-Longitudinal Submerged Arc Welding esetyenziselwa umbhobho ofikelela kwi-intshi ezingama-48 ububanzi. Eyaziwa ngokuba yinkqubo yokwenza i-JCOE.

I-SSAW/HSAW: Ukuwelda kwe-arc engaphantsi komhlaba/ukuwelda kwe-arc engaphantsi komhlaba okujikelezayo ukuya kuthi ga kwi-100 intshi ububanzi bombhobho.

Qhagamshelana Nathi ukuze ufunde ngomahluko phakathi kwepayipi ye-ERW, i-LSAW, kunye ne-SSAW.

Iintlobo zeMibhobho engenamthungo: Umbhobho ongenamthungo ojijekileyo oshushu kunye nombhobho ongenamthungo ojijekileyo obandayo

Umbhobho ongenamthungo udla ngokusetyenziswa kwiipayipi ezincinci ezinobubanzi obuphantsi (ngesiqhelo zingaphantsi kwee-intshi ezingama-24).

(Ipayipi yentsimbi engenamthungo isetyenziswa kakhulu kunepayipi edibeneyo kwiidayamitha zepayipi ezingaphantsi kwe-150 mm (ii-intshi ezi-6).

Sikwanikezela ngepayipi enkulu engenamthungo. Sisebenzisa inkqubo yokuvelisa eqengqelekayo eshushu, singavelisa ipayipi engenamthungo ukuya kuthi ga kwi-intshi ezingama-20 (508 mm) ububanzi. Ukuba ufuna ipayipi engenamthungo engaphezulu kwe-intshi ezingama-20 ububanzi, singayivelisa sisebenzisa inkqubo eshushu eyandisiweyo ukuya kuthi ga kwi-intshi ezingama-40 (1016 mm) ububanzi.

Ibanga lePipe ye-API 5L

I-API 5L ichaza la manqanaba alandelayo: Ibanga B, X42, X46, X52, X56, X60, X65, X70, kunye ne-X80.

Kukho iintlobo ngeentlobo zentsimbi kwipayipi yentsimbi ye-API 5L efana neGrade B, X42, X46, X52, X56, X60, X65, X70, kunye ne-X80. Njengoko inqanaba lentsimbi lisanda, ulawulo olulinganayo nekhabhoni luqina ngakumbi, amandla oomatshini aphezulu.

Kwakhona, ukwakheka kweekhemikhali zemibhobho ye-API 5L engenamthungo nedibeneyo yodidi oluthile akufani, umbhobho odibeneyo unemfuno ephezulu kunye nobungakanani obuncinci bekhabhoni nesalfure.

Inqanaba leNkcazelo: PSL1, PSL2

I-PSL1 kunye ne-PSL2 zahlukile ngokwemiba yovavanyo kunye neempawu zazo zekhemikhali kunye nezoomatshini.

I-PSL2 ingqongqo ngakumbi kune-PSL1 ngokwemilo yeekhemikhali, iimpawu zokuxinana, uvavanyo lokuchaphazeleka, uvavanyo olungatshabalalisiyo njalo njalo.
Uvavanyo lweMpembelelo

YiPSL2 kuphela efuna uvavanyo lwempembelelo: ngaphandle kweX80.

I-NDT: Uvavanyo Olungonakalisiyo. I-PSL1 ayifuni uvavanyo olungonakalisiyo xa kuthe kwabakho isaphulelo, uvavanyo olungonakalisiyo luyasebenza. I-PSL2 iyakwenza oko.

(Uvavanyo olungonakalisiyo: Uvavanyo olungonakalisiyo novavanyo olusemgangathweni we-API 5L lusebenzisa iindlela ze-radiographic, i-ultrasound, okanye ezinye iindlela (ngaphandle kokutshabalalisa izinto) ukufumanisa iziphene kunye nokungafezeki kwimibhobho.)

Ukuze ufumane iinkcukacha ezithe vetshe, nxibelelana nathi ukuze ufunde okungakumbi ngomahluko phakathi kwe-API 5L PSL1 kunye ne-PSL2.

Ukupakisha kunye nokuThuthwa

Ukupakisha kukhongokubanzi uhamba ze, ukubopha ucingo lwentsimbi, kakhuluomelele.
Ukuba uneemfuno ezizodwa, ungasebenzisaukupakishwa okungenamhlwa, kwaye intle ngakumbi.

Amanyathelo okhuseleko xa kupakishwa kwaye kuthuthwa imibhobho yentsimbi yekhabhoni

1.Umbhobho wentsimbi we-API 5Lkufuneka ikhuselwe kumonakalo obangelwa kukungqubana, ukukhupha kunye nokusikeka ngexesha lokuthuthwa, ukugcinwa kunye nokusetyenziswa.

2. Xa uphatha imibhobho yentsimbi yekhabhoni, kufuneka uqaphele ukuqhuma, umlilo, ityhefu kunye nezinye iingozi, kwaye ulandele iinkqubo zokusebenza zokhuseleko.

3. Ngexesha lokusetyenziswa,Ipayipi ye-API 5L yentsimbi yekhabhonikufuneka kuthintelwe ukudibana namaqondo obushushu aphezulu, izinto ezibangela ukubola, njl. Ukuba zisetyenziswa kwezi ndawo, kufuneka kukhethwe imibhobho yentsimbi yekhabhoni eyenziwe ngezinto ezikhethekileyo ezifana nokumelana namaqondo obushushu aphezulu kunye nokumelana nokubola.

4. Ukukhethwa kombhobho wentsimbi yekhabhoni kufuneka kube kokokusetyenziswa kwezinto ezifanelekileyo kunye neenkcukacha ngokwezinto ezibanzi kuquka indawo yokusetyenziswa, uhlobo oluphakathi, uxinzelelo, ubushushu njalo njalo.

5. Uhlolo oluyimfuneko kunye novavanyo kufuneka lwenziwe ngaphambi kokuba umbhobho wentsimbi yekhabhoni usetyenziswe ukuqinisekisa ukuba umgangatho wawo usemgangathweni.
