Umbhobho we-API 5L ubhekisela kumbhobho we-carbon steel osetyenziswa kwiinkqubo zokuhambisa ioli kunye negesi. Ikwasetyenziselwa ukuthutha olunye ulwelo olunjengomphunga, amanzi nodaka.

Iintlobo zokuVelisa

Ukucaciswa kwe-API 5L igubungela zombini iintlobo ezidityanisiweyo kunye nezingenamthungo.

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

Iindidi eziqhelekileyo ze-API 5L umbhobho odibeneyo zilandelayo:

ERW: I-welding yokumelana nombane, ngokuqhelekileyo isetyenziselwa i-diameter yepayipi engaphantsi kwama-intshi angama-24.

DSAW/SAW: Ukuwelda kwe-arc emacaleni kabini/i-arc entywiliselweyo, enye indlela ye-welding kwi-ERW esetyenziselwa imibhobho emikhulu yodayamitha.

LSAW: Longitudinal submerged arc welding, esetyenziselwa i-diameter yepayipi ukuya kwi-intshi ezingama-48. Ikwabizwa ngokuba yinkqubo yokwenziwa kweJCOE.

SSAW/HSAW: I-Spiral i-arc ye-arc welding / i-spiral i-arc ye-arc ye-welding, esetyenziselwa i-diameter ye-pipe ukuya kwi-intshi ezili-100.

Qhagamshelana nathi ukuze sifunde iiyantlukwano phakathi kwe-ERW, LSAW, kunye ne-SSAW pipe.

Iindidi zemibhobho engenamthungo: Umbhobho oshushu oqengqelekayo ongenamthungo

umbhobho wentsimbi ongenamthungo usetyenziswa ngokubanzi kwimibhobho edayamitha emincinci (idla ngokuba ngaphantsi kwee-intshi ezingama-24).
(Umbhobho wentsimbi ongenamthungo uyakhethwa kunombhobho odityanisiweyo wobude obungaphantsi kwe-150 mm (6 in)).
Senza umbhobho omkhulu ongenamthungo omkhulu. Ngokusebenzisa inkqubo ejikelezayo eshushu, umbhobho ongenamthungo onobukhulu obungama-intshi angama-20 (508 mm) unokuveliswa. Ukuba ufuna umbhobho ongenamthungo kunye nobubanzi> 20 ", sinokwenza umbhobho ongenamthungo ngenkqubo eshushu eyandisiweyo kunye nobubanzi ukuya kwi-40" (1016 mm).

IBanga lePipe ye-API 5L

I-API 5L ibandakanya amabanga afana neBanga B, X42, X46, X52, X56, X60, X65, X70 kunye neX80.

I-API 5L Steel Pipe ifumaneka kumabakala amaninzi entsimbi kuquka iBanga B, X42, X46, X52, X56, X60, X65, X70 and X80. Inqanaba eliphezulu lentsimbi, ulawulo olulinganayo lwekhabhoni luqina kwaye luphezulu iimpawu zamandla oomatshini.

Ngaphezu koko, i-chemical makeup ye-welded kunye ne-seamless API 5L imibhobho enebakala elifanayo lensimbi inomahluko, apho imibhobho edibeneyo ineemfuno eziphezulu kunye nomxholo ongaphantsi kwekhabhoni kunye nesulfure.

Inqanaba leNgcaciso : PSL1 , PSL2

I-PSL imfutshane kwiNqanaba lokuCacisa iMveliso kwaye iqulathe iPSL1 kunye nePSL2. Yinto efana nenqanaba lomgangatho.

I-PSL1 kunye ne-PSL2 ziyahluka kuphela ekuvavanyeni, kodwa kunye nokubunjwa kweekhemikhali kunye neempawu zomatshini.

I-PSL2 ingqongqo ngakumbi kune-PSL1 malunga nokwakheka kweekhemikhali, iipropathi eziqinile, uvavanyo lwempembelelo, uvavanyo olungonakalisi, njalo njalo.
Uvavanyo lweMpembelelo

Uvavanyo lwempembelelo - Ayifuneki kwi-PSL1, kodwa yeye-PSL2 (ngaphandle kwe-X80).
Uvavanyo olungonakalisi

I-PSL1 ayifuni uvavanyo olungonakalisi kodwa iPSL2 iyalufuna.

(Uvavanyo olungonakalisi: Uvavanyo olungonakalisi kunye novavanyo olukumgangatho we-API 5L lusebenzisa i-radiographic, i-ultrasonic, okanye ezinye iindlela (ngaphandle kokutshabalalisa izinto) ukufumanisa iziphene kunye nokungafezeki kwimibhobho.)

Ukufumana iinkcukacha ezithe vetshe, qhagamshelana nathi ukuze ufunde ngakumbi ngomahluko phakathi kwe-API 5L PSL1 kunye ne-PSL2.

Ukupakisha kunye noThutho

Ukupakishwa nguze ngokubanzi, ukubopha ucingo lwentsimbi, kakhuluyomelele.
Ukuba uneemfuno ezizodwa, ungasebenzisaukupakishwa kobungqina bomhlwa, kwaye intle ngakumbi.

Izilumkiso zokupakishwa kunye nokuthuthwa kwemibhobho ye-carbon steel
1.API 5L Steel Pipekufuneka ikhuselwe kumonakalo obangelwa kukungqubana, ukukhutshwa kunye nokunqunyulwa ngexesha lokuthutha, ukugcinwa kunye nokusetyenziswa.
2. Xa usebenzisa iibhobho ze-carbon steel, kufuneka ulandele iinkqubo zokusebenza ezikhuselekileyo zokhuseleko kwaye ubeke ingqalelo ukukhusela ukuqhuma, imililo, ubuthi kunye nezinye iingozi.
3. Ngexesha lokusetyenziswa,carbon steel API 5L Umbhobhokufuneka ugweme ukudibanisa namaqondo okushisa aphezulu, imidiya ephazamisayo, njl. Ukuba isetyenziswe kule ndawo, iipayipi zensimbi zekhabhoni ezenziwe ngezinto ezikhethekileyo ezifana nokumelana nokushisa okuphezulu kunye nokuxhatshazwa kwe-corrosion kufuneka kukhethwe.
4. Xa ukhetha imibhobho ye-carbon steel, i-carbon steel pipes yezixhobo ezifanelekileyo kunye neenkcukacha kufuneka zikhethwe ngokusekelwe kwiingcamango ezibanzi ezifana nokusingqongileyo kokusetyenziswa, iipropati eziphakathi, uxinzelelo, ukushisa kunye nezinye izinto.
5. Ngaphambi kokuba kusetyenziswe imibhobho ye-carbon steel, ukuhlolwa okufunekayo kunye neemvavanyo kufuneka zenziwe ukuze kuqinisekiswe ukuba umgangatho wabo uhlangabezana neemfuno.
