Yakagadzirirwa chimiro pombi ine giredhi Q345C/D/E uye specail pamusoro kurapwa
1. Tsanangudzo
Hollow chikamu chinonyanya kushandiswa mukugadzirwa kwesimbi uye muchina indasitiri, asi yakajairika chimiro uye giredhi haigone kugutsa imwe yakakosha nzvimbo;
Kuti ienderane nekuwedzera uye kwakakosha kudiwa, kambani yedu inogadzirira kupa chimwe chikumbiro chekukurumidzira sechinotevera:
1) chimiro chakakosha se Oval chubhu, diamond chubhu, chingwa chubhu, special-shaped chubhu
2) giredhi idzva seQ345B, Q345C, Q345D, Q355B, Q355C, Q355D, SS400, 304, 316, 310, 16Mo3, AL-6Xn nezvimwe.
3) Surface kunge epoxy primer, kupfurwa kuputika nezvimwe
Q345A, Q345B, Q345C, Q345D, Q345E ndiwo mutsauko wemagiredhi emhando, kuwedzera kubva kuA kuenda kuE, kunyanya nekuda kwekusiyana.
mukupisa tembiricha inokonzerwa nezviri mukati me microelements senge phosphorus nesarufa, zvinoreva kuti tembiricha yekukanganisa iri
zvakasiyana Uye chubhu chemakemikari anoumba michina zvivakwa.
Iyo Q345A giredhi haina kukanganisa; iyo Q345B giredhi ndeye 20 dhigirii kuvhunduka pakupisa kwekamuri; iyo Q345C giredhi ndeye 0 dhigirii kuvhunduka;
iyo Q345D giredhi ndeye -20 dhigirii kuvhunduka; iyo Q345E giredhi ndeye -40 dhigirii kuvhunduka. Pakupisa kwakasiyana-siyana, kukosha kwekuvhunduka kuri zvakare
zvakasiyana.
Iyo Q goho simba haisi pasi pe345Mp. Iyo yemhando giredhi inoratidza huwandu hwekusachena zvinhu (carbon, manganese, silicon, sulfur,
phosphorus. Icho chinhu chekusachena musimbi), uye iyo inoenderera mberi A, B, C, uye D kuenda, zvishoma izvo zvinosvibisa zvirimo.
2. Giredhi Chemical Composition
| Giredhi | Muumbi weKemikari (%) | ||||
| C | Si | Mn | P | S | |
| Q235B | ≤0.20 | ≤0.35 | ≤1.40 | ≤0.045 | ≤0.045 |
| Q345B | ≤0.20 | ≤0.50 | ≤1.70 | ≤0.035 | ≤0.035 |
| Q345C | ≤0.20 | ≤0.50 | ≤1.70 | ≤0.035 | ≤0.030 |
| Q345D | ≤0.18 | ≤0.50 | ≤1.70 | ≤0.035 | ≤0.025 |
3. Mechanical Property
| Giredhi | Mechanical Property | ||
| Kusimba Kwegoho (N/mm2)/(Mpa) | Kusimba Kwesimba (N/mm2)/(Mpa) | Kureba (%) | |
| Q235B | ≥235 | 370-500 | ≥26 |
| Q345B | 345 | 470-630 | ≥20 |
| Q345C | 345 | 470-630 | ≥21 |
| Q345D | 345 | 470-630 | ≥21 |
4. Kurapwa kwepamusoro:
Epoxy zinc-rich primer
Shot Blasting:
5. Q345 C/D/E application:
1) Q345C isina musono pombi inonyanya kushandiswa mumakanika masangano, hydraulic midziyo, inoshandiswa zvakanyanya mumakemikari, peturu, machira,
zvekurapa, chikafu, michina uye mamwe maindasitiri, anonyanya kushandiswa mumaindasitiri anodzivirira corrosion pombi, zvimiro zvikamu uye zvikamu.
2) Q345D isina musono simbi pombi inonyanya kushandiswa mungarava, boilers, kumanikidza midziyo, mafuta ekuchengetedza matangi, mabhiriji, magetsi chiteshi midziyo,
michina yekusimudza uye yekufambisa uye zvimwe zvakakwirira-mutoro wakashongedzwa zvikamu zvechimiro.
3) Q345E cryogenic machubhu anoshandiswa mukumanikidza kwakakwira uye tembiricha mapaipi uye zvishandiso zvakaita semagetsi emagetsi,
zvidyarwa zvemagetsi enyukireya, high pressure boilers, tembiricha yakakwira superheaters uye reheaters. Iyo Q345E cryogenic chubhu ine
chikamu chisina makomba uye chinoshandiswa zvakanyanya sepombi yekutakura zvinwiwa, senge mapaipi ekutakura oiri, gasi rechisikigo, gasi, mvura.
uye zvimwe zvinhu zvakasimba.
6. Zvimwe Zvikamu zvakagadzirirwa:
5. Q345 C/D/E application:
Q345D musono simbi pombi, Q345D musono pombi, Q345D simbi pombi, Q345E musono simbi pombi, musono simbi pombi yakakwirira.
kumanikidza fetiraiza midziyo, yakaderera tembiricha simbi pombi yemagetsi zvidyarwa, makemikari zvidyarwa uye boilers.
