Electrode E2594 yemewe yo gusudira itanga imikorere myiza ya Duplex

Nk'umucuruzi w'inganda ukomeye, dutanga ibyangombwaElectrode yo gusudira E2594(AWS A5.4 E2594-16), ifite umwihariko wo kugurisha AF2594-16. Iyi electrode y'icyuma kidashonga ifite kalisiyumu ya titanium, ifite karubone nkeya cyane, ikoresha azote mu buryo bw'ingenzi kugira ngo itange ubudahangarwa budasanzwe bwo kwangirika. Ubuhanga bwayo bwihariye bukora icyuma gisudira gifite ubudahangarwa buhebuje bwo kwangirika, kwangirika kwa stress corrosion (SCC), no kwangirika k'ubushyuhe.–by’ingenzi cyane ku bidukikije bikungahaye kuri chloride nk’inganda zitunganya imiti n’ibikorwa remezo byo mu mazi aho ibyuma bisanzwe bitagira umuvuduko uhagije.

Electrode'Ingufu zayo zituruka ku bushobozi bwayo bwo kugenzura imiterere ya karuboni nkeya (ubusanzwe <0.03% Celcius) hamwe na azote na molybdenum. Ibi bigeraho ku rugero rwa PRE (Pitting Resistance Equivalent) ruri hagati ya 2-40 mu gihe bigumana imiterere ya austenite-ferrite iringaniye. Imiterere y'icyuma irinda ingese hagati y'udusimba kandi ikarinda ubukana bw'ingaruka mu bushyuhe kuva kuri cryogenic kugeza kuri 300.°C (572)°F), irenga buri gihe ibisabwa na AWS A5.4 mu buryo bwa mekanike.

Mu buryo bw'imikorere, ibiElectrode yo gusudira E2594Ifite irangi rya titaniyumu-kalisiyumu ryiza rituma DC+ arc iguma neza kandi ikavanaho ibintu byose, harimo no kuyikoresha uhagaze. Irangi rigabanya ubushobozi bwo kwinjiza hydrogen (<5ml/100g), rikuraho ibyago byo kwangirika mu ngingo zifata cyane. Abasudira bavuga ko icyuma cyoroshye gitwara amazi make kandi gisubiramo ibintu byoroshye, bikongera umusaruro mu bikorwa by'ingenzi nko gukora imiyoboro y'amashanyarazi no gusudira imiyoboro.

Kwemeza imikorere byemeza ko ubutare bw'icyuma bukoreshwa mu gusudira bungana na 25.5% Cr, 9.5% Ni, 3.8% Mo, na 0.22% N. Uburyo bwigenga bwa ASTM G48 Uburyo bwo gusuzuma A bwerekana ko ubudahangarwa bw'imyobo burenze amanota asanzwe ya duplex kuri 40°C (104)°F). Ingano ya ferrite-austenite ya 45/55 igenzurwa itanga imbaraga z'umusaruro wa 650-750 MPa (94-109 ksi) hamwe n'uburebure bwa 25%+–kuzuza ibisabwa na ASME, EN, na NORSOK ku bikorwa remezo by'ingenzi.

Ku bijyanye n'ikoreshwa ry'ingufu risaba ingufu nyinshi,Electrode yo gusudira E2594Iracyari ikitegererezo cy’inganda. Ifite imikorere myiza mu buryo bwo gusukura umunyu, urubuga rwo mu mazi, n’ibikoresho bya shimi bitanga icyizere. Itangwa mu mapaki ya 4kg afunze neza kandi amara amezi 36, ibikoresho byose birimo icyemezo cyihariye. Hamagara itsinda ryacu rya tekiniki kugira ngo umenye ibisobanuro byihariye ku bijyanye no gusudira.
