Inconel 625 (Nickel Alloy 625 / UNS N06625) Phahameng - Matla Tšhilafalo-Phaephe le Tube e Kganelang - BLOG

Profaele ya Motswako le Karolo ya Intasteri

Inconel 625, yeo gape e hlaotšwego bjalo ka Nickel Alloy 625 goba UNS N06625, ke motswako wa nikele-chromium-molybdenum-niobium wo o tiilego-tharollo–matlafaditšwego wo o hlamilwego bakeng sa ditiro moo go tšhungwa le go feteletša ga themperetšha di phelago mmogo. E boloka maatla a kgethegilego, go ganetša ga go gagabela, le go tsepama ga oxidation go tšwa maemong a cryogenic go fihla go 1000℃(1832℃F).
Mophato wo o šomišwa kudu ka didirišweng tša lewatle, ditshepedišo tša tshepedišo ya dikhemikhale, diyuniti tša taolo ya tšhilafalo, di-reactor tša nuclear, le dikopano tša go ntšha moya tša entšene ya jet-ditirišo moo botshepegi bja sebopego le taolo ya tšhilafalo di swanetšego go šoma ka go bapelana. Tekatekano ya yona ya Ni-Cr-Mo-Nb e hlola filimi ya oxide yeo e iphodišago gomme e gatelela tlhaselo ya selegae le maemong a esiti le a chloride-a a humilego.

Q1: Ke tekanyetšo efe yeo ke swanetšego go e laetša bakeng sa Alloy 625 pipe vs tube?

A1:Diriša ASTM / ASMEB444/SB444 ya go swana le yonabakeng sa seamless phaephe / tube, .B705/SB705 ya go swana le yonabakeng sa welded phaephe, leB704/SB704 ya go swana le yonabakeng sa tubing.

Q2: Na UNS N06625 (Alloy 625) e ka šomišwa tirelong ya bolila (H2S)?

A2:Ee-ge e fihlelela dinyakwa tša tirelo ya porojeke ye bolila-, go akaretšwa maemo a tšhipi ao a laeditšwego le mellwane ya go thatafala.

Q3: Ke eng seo ke swanetšego go se kgopela go netefatša boleng bja Inconel 625 pele ke reka?

A3:Kgopela 3.1/3.2 MTC ka go latišišwa ga phišo, PMI, NDE (UT/hydro bjalo ka ge go laeditšwe), le teko efe goba efe ye e nyakegago ya tšhilafalo (mohlala, G28) gotee le direkhoto tša kalafo ya phišo -.
