Yintoni i-API 5L?

I-API 5L ngokubanzi ibhekisa kumgangatho wokusetyenziswa kwemibhobho yentsimbi yepayipi, equka iindidi ezimbini eziphambili:imibhobho yentsimbi engenamthungokwayeimibhobho yentsimbi edityanisiweyoOkwangoku, iintlobo zemibhobho yentsimbi edibeneyo esetyenziswa kakhulu kwimibhobho yeoyile zeziimibhobho edibeneyo ye-arc engaphantsi komhlaba(Ipayipi ye-SSAW),imibhobho edibeneyo ye-arc engaphantsi komhlaba ende(IPIYIPU YE-LSAW), kunyeimibhobho edibeneyo yokumelana nombane(ERW). Iipayipi zentsimbi ezingenamthungo zihlala zikhethwa xa ububanzi bombhobho bungaphantsi kwe-152mm.

 

Umgangatho wesizwe we-GB/T 9711-2011, iiPipes zeNtsimbi zeeNkqubo zoThutho lweePipeline kwiMizi-mveliso yePetroleum neGas, waphuhliswa ngokusekelwe kwi-API 5L.

 

I-GB/T 9711-2011 icacisa iimfuno zokuvelisa iipayipi zentsimbi ezingenamthungo nezihlanganisiweyo ezisetyenziswa kwiinkqubo zothutho lweepayipi zepetroliyam kunye negesi yendalo, ezigubungela amanqanaba amabini enkcazo yemveliso (i-PSL1 kunye ne-PSL2). Ke ngoko, lo mgangatho usebenza kuphela kwiipayipi zentsimbi ezingenamthungo nezihlanganisiweyo zokuhambisa ioyile negesi kwaye awusebenzi kwiipayipi zesinyithi ezenziwe ngentsimbi.

 

Amanqanaba eNsimbi

Iipayipi zentsimbi ze-API 5L zisebenzisa amanqanaba ahlukeneyo ezinto ezikrwada kuquka i-GR.B, i-X42, i-X46, i-X52, i-X56, i-X60, i-X70, i-X80, kunye nezinye. Iintsimbi zepayipi ezinemigangatho ye-X100 kunye ne-X120 ngoku ziye zaphuhliswa. Amanqanaba ahlukeneyo entsimbi abeka iimfuno ezahlukeneyo kwizixhobo ezikrwada kunye neenkqubo zemveliso.

 

Amanqanaba oMgangatho

Ngaphakathi komgangatho we-API 5L, umgangatho wentsimbi yombhobho uhlelwe njenge-PSL1 okanye i-PSL2. I-PSL imele iNqanaba leNkcazelo yeMveliso.
I-PSL1 ichaza iimfuno zomgangatho ngokubanzi zentsimbi yepayipi; i-PSL2 yongeza iimfuno eziyimfuneko zokwakheka kweekhemikhali, ukuqina kwe-notch, iimpawu zamandla, kunye novavanyo lwe-NDE olongezelelweyo.
