Njengomhlinzeki wezimboni ohamba phambili, sinikeza isitifiketiI-Electrode Yokushisela E2594(AWS A5.4 E2594-16), eqanjwe ngokwezentengiselwano njenge-AF2594-16. Le electrode yensimbi engagqwali embozwe nge-titanium calcium, ephansi kakhulu nge-carbon duplex ifaka okuqukethwe kwe-nitrogen okuneqhinga ukuze inikeze ukumelana nokugqwala okumangalisayo. I-chemistry yayo ekhethekile ikhiqiza insimbi ehlanganisiwe enokumelana okuphezulu nokugqwala, ukuqhekeka kokugqwala okucindezelekile (SCC), kanye nokuqhekeka okushisayo–kubaluleke kakhulu ezindaweni ezicebile nge-chloride njengezitshalo zokucubungula amakhemikhali kanye nengqalasizinda yasolwandle lapho izinsimbi ezijwayelekile ezingagqwali zingasebenzi kahle khona.
I-electrode'Ukusebenza kahle kwayo kuvela ekwakhiweni kwayo okulawulwayo kwekhabhoni ephansi (ngokuvamile <0.03% C) kuhlanganiswe nokuthuthukiswa kwe-nitrogen kanye ne-molybdenum. Lokhu kufeza ububanzi be-Pitting Resistance Equivalent (PRE) obungu-2-40 ngenkathi kugcinwa isakhiwo esincane se-austenite-ferrite esilinganiselayo. Umklamo we-metallurgical uvimbela ukugqwala kwe-intergranular futhi ulondoloza ukuqina komthelela kuwo wonke amazinga okushisa kusukela ezimweni ze-cryogenic kuya ku-300°C (572)°F), edlula njalo izidingo zomshini ze-AWS A5.4.
Ngokusebenza, lokhuI-Electrode Yokushisela E2594Ifaka ungqimba lwe-titanium-calcium oluthuthukisiwe oluqinisekisa ukuzinza kwe-DC+ arc okumangalisayo kanye nokususwa kwe-slag kuzo zonke izikhundla, kufaka phakathi ukusetshenziswa okuqondile. Ungqimba lunciphisa ukumuncwa kwe-hydrogen (<5ml/100g), luqede izingozi zokuqhekeka okubandayo emajoyintini aqinile. Abashiseli babika ukudluliselwa kwensimbi okubushelelezi ngokusabalalisa okuncane kanye nokuphinda kube lula, okuthuthukisa umkhiqizo ezisetshenzisweni ezibalulekile njengokwenziwa kwemikhumbi yokucindezela kanye nokushisela amapayipi.
Ukuqinisekiswa kokusebenza kuqinisekisa ikhemistri yensimbi yokushisela elinganiselwa ku-25.5% Cr, 9.5% Ni, 3.8% Mo, kanye no-0.22% N. Indlela Ezimele ye-ASTM G48 Ukuhlolwa kubonisa ukumelana nokugqwala kwemigodi okudlula amazinga ajwayelekile e-duplex ngo-40°C (104)°F). Ibhalansi yesigaba se-ferrite-austenite engu-45/55 elawulwayo inikeza amandla okukhiqiza angu-650-750 MPa (94-109 ksi) ngobude obungu-25%+–ukuhlangabezana nezimfuneko ze-ASME, EN, kanye ne-NORSOK zengqalasizinda ebalulekile.
Ngezicelo zokugqwala ezidinga amandla,I-Electrode Yokushisela E2594Kusalokhu kuyisilinganiso somkhakha. Ukusebenza kwayo okuqinisekisiwe ezinhlelweni zokususa usawoti emanzini, amapulatifomu asogwini lolwandle, kanye nama-reactor amakhemikhali kuqinisekisa ukuthembeka. Ihlinzekwa ngamaphakethe angu-4kg avaliwe nge-vacuum anesikhathi sokuphila sezinyanga ezingu-36, zonke izinto zifaka izitifiketi ezithile. Xhumana nethimba lethu lobuchwepheshe ukuthola imininingwane yenqubo yokushisela eqondene nesicelo.
