API 5L steel umbhobho intshayelelo

API 5Lngokuqhelekileyo ibhekisela kumbhobho wentsimbi yombhobho (umbhobho wepayipi) wokuphunyezwa komgangatho, umbhobhoumbhobho wentsimbikubandakanywa umbhobho wentsimbi engenamthungo kunye nombhobho wentsimbi odityanisiweyo iindidi ezimbini. Ngoku kumbhobho we-oyile siqhele ukusebenzisa umbhobho wentsimbi odityanisiweyo wohlobo lombhobho odityanisiweyo we-arc odityanisiweyo (SSAW)LSAW), umbhobho wokuxhathisa welding (ERW), umbhobho wentsimbi ongenamthungoisetyenziswa ngokubanzi kububanzi bombhobho obungaphantsi kwe-152mm.

Umgangatho kazwelonke we-GB / T 9711-2011 umbhobho wensimbi wenkqubo yokuthutha imibhobho kwishishini leoli kunye negesi ihlanganiswe ngokwe-API 5L.

I-GB/T 9711-2011 icacisa iimfuno zokwenziwa kwemibhobho yentsimbi engenamthungo kunye ne-welded yamanqanaba amabini okucaciswa kwemveliso (PSL1 kunye ne-PSL2) kwiinkqubo zokuthutha imibhobho kwishishini leoli negesi. Ngoko ke, umgangatho usebenza kuphela kwimibhobho yensimbi engenamthungo kunye nemibhobho yensimbi edibeneyo yokuthutha ioli kunye negesi, kwaye ayisebenzi kwimibhobho yentsimbi.

Steel amaBanga

Amanqanaba ensimbi yezinto eziluhlaza kwimibhobho yensimbi yalo mgangatho we-API 5L yi-GR.B, X42, X46, X52, X56, X60, X70, X80, njl njl. Amanqanaba entsimbi yeemibhobho zetsimbi ahlukile, kunye neemfuno zezinto eziluhlaza. kunye nemveliso nayo yahlukile, kodwa ukulingana kwekhabhoni phakathi kwamabakala entsimbi ahlukeneyo alawulwa ngokungqongqo.

 

Imigangatho yomgangatho

Kwinqanaba lombhobho we-API 5L, imigangatho yomgangatho (okanye iimfuno) zombhobho wensimbi zihlukaniswe kwi-PSL1 kunye ne-PSL2. I-PSL sisishunqulelo senqanaba lokuchazwa kwemveliso.

I-PSL1 ibonelela ngenqanaba eliqhelekileyo leemfuno zomgangatho wombhobho; I-PSL2 yongeza iimfuno ezinyanzelekileyo zokwakheka kweekhemikhali, ukuqina okuphawulweyo, iipropathi zamandla, kunye nee-NDE ezongezelelweyo.
