Semutengesi wepamusoro weindasitiri, tinopa certificationKukwevera Electrode E2594(AWS A5.4 E2594-16), inotengeswa seAF2594-16. Iyi electrode yesimbi isina tsvina ine titanium calcium-coated, ine ultra-low carbon duplex ine nitrogen yakawanda kuti ipe simba rekudzivirira ngura. Kemikari yayo yakasarudzika inogadzira simbi ye weld ine simba rekudzivirira gomba, stress corrosion cracking (SCC), uye thermal cracking.–Zvakakosha zvikuru kunzvimbo dzine chloride yakawanda semafekitori ekugadzirisa makemikari uye zvivakwa zvemugungwa uko simbi dzisingasvibi dzakajairwa dzinoshanda zvisina kunaka.
Iyo electrode'Kushanda kwayo kunobva mukuumbwa kwayo kwekabhoni shoma (kazhinji <0.03% C) pamwe chete nenitrogen ne molybdenum. Izvi zvinoita kuti pave nePitting Resistance Equivalent (PRE) kubva pa2 kusvika ku40 ukuwo zvichichengetedza chimiro che austenite-ferrite chakaringana. Dhizaini yesimbi inodzivirira ngura pakati pegranular uye inochengetedza kusimba kwemhedzisiro pakupisa kubva pamamiriro e cryogenic kusvika pa300 C.°C (572)°F), zvichiramba zvichipfuura zvinodiwa neAWS A5.4 zvemakanika.
Pakushanda, izviKukwevera Electrode E2594ine titanium-calcium coating yakagadziriswa inoita kuti DC+ arc igare zvakanaka uye ibvise tsvina munzvimbo dzese, kusanganisira kushandiswa kwakamira. Coating iyi inoderedza kunyudzwa kwehydrogen (<5ml/100g), ichibvisa njodzi dzinokanganisa majoini anodzikamisa zvakanyanya. Vagadziri ve welding vanoti simbi inopfava inotapudzwa zvishoma uye inodzokororwa zviri nyore, zvichiwedzera kugona kwayo mukushandiswa kwakakosha senge kugadzira midziyo ye pressure ne welding ye pipeline.
Kusimbiswa kwekushanda kunoratidza kuti simbi yakasungirirwa inokwana 25.5% Cr, 9.5% Ni, 3.8% Mo, uye 0.22% N. Nzira yeASTM G48 Yakazvimiririra Kuedza kunoratidza kuti ngura inodarika magiredhi enguva dzose ne40°C (104)°F). Kuenzana kwechikamu che45/55 cheferrite-austenite kunopa simba rekukohwa re650-750 MPa (94-109 ksi) ne25%+ elongation.–kusangana nezvinodiwa neASME, EN, uye NORSOK zvezvivakwa zvakakosha.
Pakushandisa ngura zvakanyanya,Kukwevera Electrode E2594Inoramba iri chiyero cheindasitiri. Kushanda kwayo kwakaratidzwa mukubvisa munyu, mapuratifomu ekunze, uye ma reactor emakemikari kunoita kuti ive yakavimbika. Inopihwa mumapaketi e4kg akavharirwa vacuum ane hupenyu hwemwedzi makumi matatu nematanhatu, zvese zvinoshandiswa zvinosanganisira zvitupa zvakanangana nebatch. Bata timu yedu yehunyanzvi kuti uwane marongero ekushandisa welding.
