Umbhobho womgca we-API 5L (umbhobho ongenamthungo kunye ne-welded) kuwo onke amabakala ane-PSL1 kunye ne-PSL2 inkcazo yeemveliso ezimbini, zihluke ekubunjweni kweekhemikhali, iinkqubo zokuvelisa, amandla omatshini, unyango lokushisa, iirekhodi zokuvavanya, ukulandelelana njl njl.

Imibhobho yomgca kwi-API 5L PSL2 iphezulu kunePSL1

I-PSL ligama elifutshane lomgangatho womgangatho wemveliso.Umgangatho womgangatho wemveliso wombhobho womgca une-PSL1 kunye ne-PSL2, kwakhona sinokuthi umgangatho womgangatho owahlulwe kwi-PSL1 kunye ne-PSL2.I-PSL2 iphezulu kune-PSL1, kungekhona nje umgangatho wokuhlola owahlukileyo, kunye nepropati yeekhemikhali, imigangatho yamandla omatshini yahlukile.Ngoko xa ubeka umyalelo we-API 5L umbhobho womgca, kufuneka kuchazwe ngokucacileyo ubungakanani, amabakala achazwe ngokubanzi, kufuneka acacise umgangatho womgangatho wokuvelisa, i-PSL1 okanye i-PSL2.

I-PSL2 ingqongqo ngakumbi kune-PSL1 kwiipropathi zekhemikhali, amandla okuqina, uvavanyo olungonakalisi, kunye novavanyo lwempembelelo.

Iindlela ezahlukeneyo zovavanyo lweempembelelo zePSL1 kunye nePSL2

I-API 5L PSL1 ipayipi yomgca wensimbi ayifuni ukwenza uvavanyo lwempembelelo.

Kwi-API 5L PSL2 umbhobho womgca wensimbi, ngaphandle kweBanga le-X80, onke amanye amabakala e-API 5L umbhobho womgca wawufuna uvavanyo lwempembelelo kwiqondo lokushisa le-0.℃.I-avareji yexabiso le-Akv: i-longitudinal direction≥41J, indlela enqumlayo≥27J.

Kwi-API 5L yeBakala X80 PSL2 umbhobho womgca, ku-0℃kubo bonke ubungakanani, impembelelo yovavanyo lwe-avareji yexabiso le-Akv: ulwalathiso lwelongitudinal≥101J, indlela enqumlayo≥68J.

Uvavanyo oluhlukeneyo lwe-hydraulic ye-API 5L umbhobho womgca kwi-PSL1 kunye ne-PSL2

Kwi-API 5L ye-PSL2 yombhobho womgca uya kwenza uvavanyo lwe-hydraulic kumbhobho ngamnye, kwaye kwi-API yomgangatho wenkcazo engavumelekanga ukuba ibe novavanyo olungonakalisi endaweni yovavanyo lwe-hydraulic, oku kwakhona umehluko omkhulu phakathi komgangatho waseTshayina kunye nomgangatho we-API 5L.Kwi-PSL1 ayifuneki Uvavanyo olungonakalisi, kwi-PSL2 iya kwenza uvavanyo olungonakalisi kumbhobho ngamnye.

Ukubunjwa kweekhemikhali ezahlukeneyo ze-API 5L umbhobho womgca kwi-PSL1 kunye ne-PSL2

Ukubunjwa kweekhemikhali kunye namandla omatshini kukwahluke phakathi kwe-API 5L PSL1 umbhobho womgca kunye ne-API 5L PSL2 umbhobho womgca.Ngeenkcukacha ezithe vetshe njengoko kungezantsi.I-API 5L PSL2 inezithintelo kunye nomxholo olinganayo wekhabhoni, apho i-carbon mass fraction enkulu kune-0.12%, kwaye ilingana okanye ngaphantsi kwe-0.12%.I-CEQ eyahlukileyo iya kusetyenziswa.Ngombhobho womgca kwi-PSL2 amandla e-tensile anemida ephezulu.Ulwazi oluthe vetshe nceda ujonge i-API 5L Ucaciso lwecandelo 9.2 kunye ne-9.3.

Ewe, sifuna zonke ii-odolo zamazwe ngamazwe ukuba zibe ne-odolo encinci eqhubekayo.Ukuba ujonge ukuthengisa kwakhona kodwa ngexabiso elincinci kakhulu, sicebisa ukuba ujonge iwebhusayithi yethu
