Umbhobho we-API 5Lngumbhobho wentsimbi yekhabhoni osetyenziswa kakhulu kwimizi-mveliso yeoyile negesi. Ikwasebenza njengendlela yokuthwala ezinye izinto ezinje ngomphunga, amanzi kunye nodaka.

Iintlobo zoMveliso

I-API 5L isebenza kuzo zombini iipayipi ezitshixiweyo 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.

I-DSAW/ I-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).

Sikwagcina umbhobho omkhulu ongenamthungo. Sisebenzisa indlela yokuqengqeleka ngobushushu, singavelisa umbhobho ongenamthungo ofikelela kwi-20" (508 mm). Ukuba ufuna umbhobho ongenamthungo ongaphezulu kwe-20" ububanzi, singawenza ofikelela kwi-40" (1016 mm) ububanzi ngokusebenzisa indlela eshushu.

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 olungatshabalalisiyo: Uvavanyo olungatshabalalisiyo (NDT) kunye novavanyo lwe-NDT (xa kusetyenziswa iinkqubo zovavanyo lwe-NDT ezibhalwe kwi-API 5L) kukusetyenziswa kolunye okanye ngaphezulu kobuchule bovavanyo olungatshabalalisiyo obufana ne-radiography, i-ultrasonic (US), okanye ezinye (ezingonakaliswanga zizinto) ukuchonga iziphene kunye nokungafezeki kwimibhobho.)

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.Ngexesha lokuThuthwa nokuGcinwa
Umbhobho wentsimbi we-API 5Lkufuneka ikhuselwe ekutshatyalalisweni, ekucinezelweni, ekusikweni okanye nakweyiphi na enye ingozi yoomatshini ngexesha lokupakisha, ukuthutha, ukugcina kunye nokuphatha.

2. Iindlela Zokuphatha Ngokukhuselekileyo
Xa usebenza neimibhobho yentsimbi yekhabhoni, soloko uthatha amanyathelo okhuseleko aqhelekileyo ukuze uphephe iingozi ezifana nokuqhuma, imililo, okanye ukuvezwa kwiikhemikhali ezinobungozi.

3. Imeko yeNkonzo
Akufuneki usebenziseImibhobho yentsimbi yekhabhoni ye-API 5Lkwiindawo ezinobushushu obuphezulu, ezirhabaxa, okanye naziphi na ezinye iintlobo zeendawo ezingqongileyo ezinzima. Kwezi zicelo, khetha imibhobho eyenziwe ngemigangatho ekhethekileyo ekwaziyo ukumelana nobushushu obuphezulu okanye ukugqwala.

4.Ukukhethwa kwezinto kunye neenkcukacha
Gqiba ngezinto zombhobho kunye nomgangatho emva kokuqwalasela ngononophelo iimeko zokusebenza oko kukuthi uhlobo lwendalo esingqongileyo, uhlobo lweMedium, uxinzelelo kunye nobushushu kunye nokusetyenziswa, njl.

5. Uvavanyo kunye novavanyo lwangaphambi kokusetyenziswa
Umgca wePope kufuneka uhlolwe ngaphambi kokuba usetyenziswe ukuqinisekisa umgangatho kunye nokusebenza.
