Intshayelelo yombhobho wentsimbi ye-API 5L

I-API 5Lngokubanzi ibhekisa kumbhobho wentsimbi yombhobho (umbhobho wombhobho) wokuphunyezwa komgangatho, umbhobhoumbhobho wentsimbikuquka umbhobho wentsimbi ongenamthungo kunye nombhobho wentsimbi odibeneyo iindidi ezimbini. Okwangoku kumbhobho weoyile besisoloko sisebenzisa umbhobho wentsimbi odibeneyo oluhlobo lwepayipi edibeneyo ejikelezileyo ejikelezileyo (spiral submerged arc welded pipe) (I-SSAW), umthungo othe tye ongaphantsi komhlaba ojikeleziweyo nge-arc (I-LSAW), umbhobho wokuwelda ochaseneyo (I-ERW), umbhobho wentsimbi ongenamthungongokubanzi isetyenziswa kwimibhobho ububanzi bayo bungaphantsi kwe-152mm.

Umbhobho wentsimbi we-GB/T 9711-2011 osemgangathweni kazwelonke wenkqubo yokuthutha imibhobho kushishino lweoyile negesi uhlanganiswe ngokwe-API 5L.

I-GB/T 9711-2011 ichaza iimfuno zokwenziwa kwemibhobho yentsimbi engenamthungo nedibeneyo yamanqanaba amabini enkcazo yemveliso (i-PSL1 kunye ne-PSL2) kwiinkqubo zothutho lwemibhobho kushishino lweoyile negesi. Ke ngoko, umgangatho usebenza kuphela kwimibhobho yentsimbi engenamthungo kunye nemibhobho yentsimbi edibeneyo yothutho lweoyile negesi, kwaye awusebenzi kwimibhobho yesinyithi esenziwe ngentsimbi.

Amanqanaba eNsimbi

Amanqanaba entsimbi yezinto ezikrwada zeepayipi zentsimbi zale API 5L standard yi-GR.B, X42, X46, X52, X56, X60, X70, X80, njl. Amanqanaba entsimbi yeepayipi zentsimbi ahlukile, kwaye iimfuno zezinto ezikrwada kunye nemveliso nazo zahlukile, kodwa izinto ezilingana nekhabhoni phakathi kwamanqanaba entsimbi ahlukeneyo zilawulwa ngokungqongqo.

 

Imigangatho yomgangatho

Kwimigangatho yepayipi ye-API 5L, imigangatho yomgangatho (okanye iimfuno) zepayipi yentsimbi yahlulwe yaba yi-PSL1 kunye ne-PSL2. I-PSL sisifinyezo senqanaba leenkcukacha zemveliso.

I-PSL1 ibonelela ngemigangatho ngokubanzi yeemfuno zomgangatho wepayipi; i-PSL2 yongeza iimfuno eziyimfuneko zokwakheka kweekhemikhali, ukuqina okuqhekekileyo, iimpawu zamandla, kunye nee-NDE ezongezelelweyo.
