Umuyoboro w'ubushyuhe buke (A333 A334 Gr.6 Gr.3)
HASI PIPE Z'AGATEGANYO
Ingano yimiyoboro - 1/4 ”Nominal to 42” OD
Uburebure bw'urukuta - Gahunda ya 10 kugeza kuri XXH
Ibyuma bya karubone bifite ubushyuhe buke byatejwe imbere cyane cyane kugirango bikoreshe mubushyuhe buke cyane cyane kubikoresho byo gusudira.
Nibiri munsi ya karubone (0,20 kugeza 0,30%), manganese yo hejuru (0,70 kugeza 1.60%), silikoni (0.15 kugeza 0,60%), ifite imiterere-yimbuto nziza hamwe na karbide imwe.Biranga imbaraga ziciriritse hamwe no gukomera kugeza - 50 ° F (—46 ° C).
Kugirango tunonosore ingano no kunoza imiterere no gusudira, ibyuma bya karubone bishobora kuba birimo 0.01 kugeza 0.04% columbium.Byitwa ibyuma bya columbium, bikoreshwa mumashanyarazi, kwibagirwa, ibikoresho, imashini, hanyuma bipfa na gage.Kugera kuri 0.15% sulfure, cyangwa 0,045 fosifore, bituma bakora-kubuntu, ariko bigabanya imbaraga.
LTCS ni icyuma cya Nickel gishingiye ku byuma bikoreshwa cyane cyane mubushyuhe buke munsi - 150 deg F.
SA-203 Icyapa Icyuma Icyiciro A, B, D, E na F Nickle Amashanyarazi.Kubushyuhe buke (-150 deg F)
Ubushyuhe Buke bwa Carbone Ibyuma ASTM A334 Gr.1
ASTM A333 —— Umuyoboro w'icyuma udafite ubudodo na Welded for Service-Ubushyuhe buke:
Ahanini Icyiciro
Icyiciro cya 1, Icyiciro cya 3, Icyiciro cya 4, Icyiciro cya 6, Icyiciro cya 7, Icyiciro cya 8, Icyiciro cya 9, Icyiciro cya 10, Icyiciro cya 11;
Ubushyuhe buke bwa karubone ibyuma bizimya ubushyuhe muri A3 + (30 ~ 50) ℃, mubikorwa, mubisanzwe bishyirwa kumurongo wo hejuru.Umuvuduko mwinshi wubushyuhe urashobora gukora umuvuduko muke, kugabanya okiside hejuru, kandi birashobora kunoza imikorere.Igikorwa ni kimwe austenite, bizasaba umwanya uhagije wo gufata.Niba mubyukuri itanura ryububiko, byakenerwa kuba byongerewe igihe cyo gufata.Bitabaye ibyo, hashobora kubaho ubukana budahagije kubera ubushyuhe butaringaniye buterwa na phenomenon.Ariko, gufata umwanya ni muremure cyane, bizagaragara kandi ibinyampeke bito, okiside hamwe na decarbonisiyasi mbi bigira ingaruka kumyuka.Twizera ko niba itanura ryashyizweho rirenze ibyangombwa, gushyushya igihe cyo kongerwa 1/5.
Umuyoboro muke wa karubone ibyuma kubera gukomera gukomeye, bigomba gufata igipimo kinini cyo gukonjesha cya 10% cyumunyu.Igicapo mumazi, kigomba gukomera, ariko ntigikonje, niba 45 # ibyuma bisobanutse bikonje muri brine, birashoboka guturika kumurimo, ibi ni ukubera ko iyo igihangano gikonje kigera kuri 180 ℃, austenite ihinduka mumubiri wamafarasi. tissue iterwa no guhangayika birenze urugero.Kubwibyo, mugihe icyuma kizimya nubushyuhe bikonje vuba kuri ubu bushyuhe, hagomba gufatwa ingamba zo gukonja buhoro.
Nkuko ubushyuhe bwamazi bugoye kubyumva, uburambe bubazwa mubikorwa, mugihe amazi ahagaritse ibihangano, urashobora gukonjesha (urugero: gukonjesha amavuta birashobora kuba byiza).Mubyongeyeho, igihangano cyakazi mumazi, igikorwa gikwiye kigomba kuba kijyanye na geometrie yibikorwa, nkimyitozo isanzwe.Gukonjesha guhagarara hamwe hiyongereyeho akazi gahagaze, bikavamo gukomera kutaringaniye, guhangayika kutaringaniye hasigara ihinduka rinini ryakazi, ndetse no guturika.
