Iipayipi zentsimbi ezixineneyo nezinganyangekiyo zokubola (CRA) zeNkonzo emuncu kunye nezicelo zaselwandle

Kwihlabathi elinzima lokuthuthwa kweoyile negesi, ukugqwala lutshaba oluphambili lokuthembeka kwempahla kunye nobude bokusebenza. Iipayipi ezithutha izixhobo ezihlaselayo eziqulethei-hydrogen sulfide (H₂S),ikharbon diokside (CO₂),iikloridi, kwaye ii-organic acids zijongene nemingcipheko enzima yokuwohloka. Ukulwa noku, eli shishini lisebenzise izisombululo zezinto eziphucukileyo ezifanaUmbhobho ogqunywe yi-API 5LDkwayeUmbhobho ofakwe i-API 5LDEziimibhobho ye-alloy enganyangekiyo nokugqwala (CRA)zibonelela ngentsebenziswano epheleleyo: amandla olwakhiwo lwentsimbi yekhabhoni kunye nomqobo wokugqwala weealloy ezikumgangatho ophezulu.

Intsimbi yeWomic, isebenzisa udibaniso lwayo olukhethekileyo lwe-“Plate-to-Pipe” kunye nenkampani yayo engumzali,IsiWomicI-Steel Group, iphambili kule teknoloji. Inokufikeleleka kwi-premiumiipleyiti ezibotshelelwe ngesinyithiiveliswe nguIsiWomicIWomic Steel, isixeko esivelisa iipayipi ezisemgangathweni ophezulu kunye nesakhiwo sanamhlanje esikumgama weekhilomitha ezi-5 ukusuka apho.imibhobho edibeneyo ye-bimetallickwiiprojekthi zaselwandle, zaselwandle, nezaselwandle kwihlabathi liphela. Esi sikhokelo sibanzi sihlola imeko-bume yobuchwephesha yemibhobho enganyangekiyo yi-API 5LD, sigxile kwiindlela zokuvelisa, ukukhethwa kwezinto, kunye nemigangatho yobunjineli.

Yintoni i-API 5LD Clad Pipe kunye ne-Lined Pipe?

I-API Spec 5LDngumgangatho wehlabathi olawulayoUmbhobho wentsimbi ogqunywe nge-CRA okanye ofakwe imigcakwiinkqubo zothutho lwemibhobho kwimizi-mveliso yepetroleum negesi yendalo.Umbhobho wentsimbi ogqunywe yi-API 5LDyimveliso edityanisiweyo equlathe iileya ezimbini ezahlukeneyo:

1. Umbhobho Wokuxhasa Intsimbi Yekhabhoni:Inika amandla oomatshini okumelana noxinzelelo lwangaphakathi, imithwalo yangaphandle, kunye nokugoba. Ngokwesiqhelo yenzelweI-API 5LokanyeI-ISO 3183iinkcukacha (amanqanaba afana ne-X52, X60, X65).
2. Umaleko we-Alloy Resistant Corrosion (CRA):Isebenza njengomqobo oqinileyo kwiincindi ezibolayo. Olu maleko lunokuba yintsimbi engatyiwayo (umz.,316L), intsimbi engenasici kabini (umz.,2205), okanye ii-alloys ezisekelwe kwi-nickel (umz.,625,825).

Olu lwakhiwo oludibeneyo luphucula iindleko zomjikelo wobomi ngokusebenzisa iindleko ezibizayoIzixhobo ze-CRAkuphela apho kufuneka khona—kumphezulu ongaphakathi—ngelixa amandla okuthwala umthwalo evela kwintsimbi yekhabhoni engabizi kakhulu.

Imigangatho ephambili yamazwe ngamazwe yeepayipi ezimelana nokugqwala
