Umuyoboro wuburyo bwihariye hamwe nicyiciro Q345C / D / E hamwe nubuvuzi bwihariye
1. Ibisobanuro
Igice cyimbere gikoreshwa cyane cyane mubyuma byinganda ninganda zimashini, ariko imiterere nicyiciro gisanzwe ntibishobora guhaza ahantu runaka bidasanzwe;
Kugirango rero duhuze ibyifuzo byinshi kandi bidasanzwe, isosiyete yacu yitegura gutanga ibyifuzo byihutirwa byubusa nkibi bikurikira:
1) imiterere idasanzwe nka Oval tube, umuyoboro wa diyama, umuyoboro wumugati, umuyoboro udasanzwe
2 grade icyiciro gishya nka Q345B, Q345C, Q345D, Q355B, Q355C, Q355D, SS400, 304, 316, 310, 16Mo3, AL-6Xn nibindi
3) Ubuso nka epoxy primer, guturika kurasa nibindi
Q345A, Q345B, Q345C, Q345D, Q345E ni itandukaniro ryamanota meza, ryiyongera kuva A kugeza kuri E, cyane cyane kubitandukaniro
mubushyuhe bwingaruka ziterwa nibiri muri microelements nka fosifore na sulfuru, bivuze ko ubushyuhe bwingaruka ari
zitandukanye Kandi tube chimique yibigize imashini.
Icyiciro cya Q345A nta ngaruka; icyiciro cya Q345B ni impanuka ya dogere 20 kubushyuhe bwicyumba; icyiciro cya Q345C ni impanuka ya dogere 0;
icyiciro cya Q345D ni -20 dogere; icyiciro cya Q345E ni -40 dogere. Kubushyuhe butandukanye, agaciro ko guhungabana nako
bitandukanye.
Q umusaruro wimbaraga ntabwo uri munsi ya 345Mp. Urwego rw'ubuziranenge rwerekana ingano y'ibintu byanduye (karubone, manganese, silikoni, sulfuru,
fosifore. Nibintu byanduye mubyuma), kandi uko A, B, C, na D bigenda, niko ibintu bitanduye bihari.
Icyiciro cya shimi

| Imbaraga Zitanga (N / mm2) / (Mpa) | Imbaraga zingana (N / mm2) / (Mpa) | Kurambura (%) | |
| Q235B | ≥235 | 370-500 | ≥26 |
| Q345B | 345 | 470-630 | ≥20 |
| Q345C | 345 | 470-630 | ≥21 |
| Q345D | 345 | 470-630 | ≥21 |
4. Kuvura hejuru:
Epoxy zinc ikungahaye cyane primer
Guturika kw'amasasu:
5. Q345 C / D / E gusaba:
1) Q345C umuyoboro udafite ubudodo ukoreshwa cyane mubigo byubukanishi, ibikoresho bya hydraulic, bikoreshwa cyane mubumashini, peteroli, imyenda,
ubuvuzi, ibiryo, imashini nizindi nganda, zikoreshwa cyane cyane mu miyoboro irwanya ruswa, ibice byubatswe nibice.
2) Q345D umuyoboro wicyuma udafite ubudodo ukoreshwa cyane cyane mumato, guteka, ubwato bwumuvuduko, ibigega bibika amavuta, ibiraro, ibikoresho bya sitasiyo,
guterura no gutwara imashini nibindi bikoresho byinshi biremereye gusudira ibice byubatswe.
3) Q345E imiyoboro ya kirogenike ikoreshwa mumuvuduko mwinshi hamwe numuyoboro mwinshi wubushyuhe nibikoresho nkamashanyarazi,
amashanyarazi ya kirimbuzi, ibyuka byumuvuduko mwinshi, ubushyuhe bukabije nubushyuhe. Umuyoboro wa Q345E cryogenic ufite
igice kitagaragara kandi gikoreshwa cyane nk'umuyoboro wo gutwara amazi, nk'imiyoboro yo gutwara peteroli, gaze gasanzwe, gaze, amazi
n'ibikoresho bimwe bikomeye.
6. Ibindi bice byabigenewe:
5. Q345 C / D / E gusaba:
Q345D umuyoboro w'icyuma udafite ikidodo, Q345D umuyoboro udafite ikidodo, umuyoboro w'icyuma Q345D, umuyoboro w'icyuma Q345E, umuyoboro w'icyuma udafite icyuma
ibikoresho by'ifumbire mvaruganda, umuyoboro muto wicyuma giciriritse kumashanyarazi, inganda za chimique na boiler.
