Yintoni i-API 5L?

I-API 5L ibhekisa ngokubanzi kumgangatho wokuphunyezwa kwemibhobho yentsimbi yombhobho, ebandakanya iindidi ezimbini eziphambili:imibhobho yentsimbi engenamthungokwayeimibhobho yentsimbi edityanisiweyo. Okwangoku, iintlobo zemibhobho yentsimbi esetyenziswa ngokuqhelekileyo kwimibhobho yeoliimibhobho edityanisiweyo ye-arc(SAW PIPE),imibhobho edityanisiweyo ye-arc yobude(LSAW PIPE), kunyeukuxhathisa kombane imibhobho edityanisiweyo(ERW). Imibhobho yentsimbi engenamthungo idla ngokukhethwa xa idiameter yombhobho ingaphantsi kwe-152mm.

 

Umgangatho wesizwe we-GB / T 9711-2011, iMibhobho yeNsimbi yeeNkqubo zoThutho lwePipeline kwiPetroleum kunye neGesi yeNdalo, yaphuhliswa ngokusekelwe kwi-API 5L.

 

I-GB/T 9711-2011 icacisa iimfuno zokwenziwa kwemibhobho yentsimbi engenamthungo kunye ne-welded esetyenziswa kwiinkqubo zothutho zepetroleum kunye negesi yendalo, equka amanqanaba amabini okucaciswa kwemveliso (PSL1 kunye nePSL2). Ngoko ke, lo mgangatho usebenza kuphela kwimibhobho yentsimbi engenamthungo kunye ne-welded yokuhanjiswa kweoli kunye negesi kwaye ayisebenzi kwimibhobho yentsimbi.

 

amaBanga entsimbi

Imibhobho yentsimbi ye-API 5L isebenzisa amabakala ahlukeneyo emathiriyeli ekrwada kuquka i-GR.B, X42, X46, X52, X56, X60, X70, X80, kunye nezinye. Iintsimbi zombhobho ezinamabakala X100 kunye ne-X120 ziphuhlisiwe ngoku. Amanqanaba entsimbi ahlukeneyo abeka iimfuno ezicacileyo kwizinto eziluhlaza kunye neenkqubo zokuvelisa.

 

Amanqanaba oMgangatho

Ngaphakathi komgangatho we-API 5L, umgangatho wensimbi wepayipi uhlelwa njenge-PSL1 okanye i-PSL2. I-PSL imele iNqanaba lokuCaluswa kweMveliso.
I-PSL1 ichaza iimfuno zomgangatho jikelele wentsimbi yombhobho; I-PSL2 yongeza iimfuno ezisisinyanzelo zokwakheka kweekhemikhali, ukuqina kwenotshi, iipropathi zamandla, kunye novavanyo olongezelelweyo lwe-NDE.
