Womic Steel imaze imyaka 20 yigaragaza nk'umutanga serivisi yizewe ku bikoresho n'ibisubizo byiza. Ifite umurava wo gukora neza, iyi sosiyete ikora ku nganda zitandukanye, itanga ibisubizo byihariye kugira ngo ihuze n'ibyo ikeneye. Ibikoresho byabo birimo ibikoresho by'igiciro cya ASTM A335 P91 Type 2, bituruka ku nganda mpuzamahanga zemewe kandi bihora bivugururwa kugira ngo bihuze n'ibipimo byo hejuru. Womic Steel yihariye mu gutanga ibikoresho bya P91 bikoreshwa mu ngufu nyinshi, harimo imiyoboro, ibikoresho, valve, flanges, n'ibindi, bityo bigatuma abakiriya babona ibicuruzwa byiza cyane.

Ibipimo ngenderwaho bishobora gutangwa na Womic Steel Group:

Ibiranga by'ingenzi bya ASTM A335 P91 Type 2 tubes
ASTM A335 P91 Ubwoko bwa 2 ni icyuma cya chrome-moly alloy kizwiho imbaraga zacyo zidasanzwe, ubushobozi bwo guhangana n'ubushyuhe, n'imbaraga zo gucikamo ibice. Gishyirwa mu cyiciro cy'icyuma cya creep strength-enhanced ferritic (CSEF), bigatuma kiba cyiza cyane mu gukoresha ubushyuhe bwinshi n'umuvuduko mwinshi. Ibikoresho bikorerwa mu buryo bwihariye bwo gutunganya ubushyuhe:

Ubushyuhe buri ku gipimo cya 1050 °C.

Gukonjesha umwuka kugeza kuri 200 °C.

Gushyushya kuri 760 °C.

Iyi gahunda yongera imbaraga zayo zo guhindagurika no kuramba, bigatuma iba amahitamo meza ku bidukikije bisaba imbaraga nyinshi.

Imiterere n'akamaro k'imiyoboro y'icyuma ya ASTM A335 P91
Chromium (9%): Yongera imbaraga mu bushyuhe bwinshi, irwanya ogisijeni, n'imiterere ya mekanike.

Molybdenum (1%): Ituma uruhu rworoshye, idashobora kwangirika, kandi ikagira imbaraga zo kuzamuka mu bushyuhe bwinshi.

Vanadium na Columbium/Niobium: Yongera imbaraga zo gukurura no kwirinda umunaniro ukabije w'ubushyuhe.

Ibyiza by'imiyoboro y'icyuma ya ASTM A335 P91
Ubunini bw'urukuta bugabanuka: Bituma ibice byoroheje bigabanuka, igihe cyo gusudira kigabanuka, kandi ibyuma bito bigabanya ubwinshi.

Igihe cyo kunanirwa cyane n'ubushyuhe: Kugeza ku nshuro 10 kurusha izabanjirije nka T22 cyangwa P22.

Ubushyuhe bw'imikorere bwiyongera: Byongera imikorere myiza mu bikorwa birimo ubushyuhe bwinshi.

Imikoreshereze y'imiyoboro y'icyuma ya ASTM A335 P91
P91 ikoreshwa cyane mu nganda zikenera ibikoresho bishobora kwihanganira ubushyuhe n'umuvuduko ukabije. Ikoreshwa risanzwe ririmo:

Ingufu zikoreshwa mu gutanga amashanyarazi: Amashanyarazi, imiyoboro yo kongera gushyushya, n'inganda zikora amashanyarazi.

Inganda zikora peteroli: Ibikoresho bishyushya, ibikoresho bitunganya gaze, na serivisi zo mu bicuruzwa bya peteroli.

Imiyoboro y'amazi ikoresha ubushyuhe bwinshi: Ikwiriye gukoreshwa mu gupfunyika, gukurura no gusudira.

Imiterere ya ASTM A335 P91 Steel Tubes
Imiterere ya P91 mu binyabutabire ituma ikora neza cyane:

Karuboni: 0.08% – 0.12%

Manganese: 0.30% – 0.60%

Chromium: 8.00% – 9.50%

Molibdenum: 0.85% – 1.05%

Vanadium: 0.18% – 0.25%

Azote: 0.030% – 0.070%

Ibindi bintu: Nickel, aluminium, columbium, titanium, na zirconium mu rugero rugenzurwa.

Imiterere ya mekanike
Ingufu zo Gukurura: Nibura 85.000 PSI (585 MPa).

Ingufu z'umusaruro: Nibura 60.000 PSI (415 MPa).

Gusudira no Gutunganya Ubushyuhe bwa ASTM A335 P91 Imiyoboro y'Icyuma
Gusudira P91 bisaba gukurikiza cyane amabwiriza kugira ngo imiterere yayo ikomeze kuba myiza:

Gushyushya: Ni ngombwa kugira ngo hirindwe ko hangirika haterwa na hydrogen.

Kugenzura ubushyuhe hagati y’amashanyarazi: Bibungabungwa hakoreshejwe uburyo bugezweho bwo gushyushya bukoresha induction.

Uburyo bwo kuvura ubushyuhe nyuma yo gusudira (PWHT): Ni ingenzi cyane kugira ngo imiterere y’icyuma igerweho kandi hirindwe ko ibintu byangirika.

Ama-electrode yo gusudira: Agomba kuba ahuye n'imiterere y'ibikoresho bya mbere.

Kuki wahitamo imiyoboro y'icyuma ya Womic Steel ASTM A335 P91?
Ibikoresho byinshi: Ibikoresho bya P91 byiza cyane bikwiranye n'ibyo ukeneye byose.

Ubuhanga: Itsinda ry'inararibonye rigufasha guhitamo ibikoresho no kubikoresha.

Kwiyemeza gukora ubuziranenge: Ibikoresho byiza cyane biva mu nganda zemewe gusa.

Ku bijyanye n'ibisabwa byose bya ASTM A335 P91 Type 2, hamagara Womic Steel uyu munsi. Itsinda ryabo ryiteguye gutanga ibisubizo birenze ibyo witeze no gutanga ibikoresho byiza cyane ku mishinga yawe.
