1. Iyo pombi yesimbi inotora Q235B, welded steel pipe (GB / T 3092) kana seamless simbi pombi (GB / T 8162) inogona kushandiswa.

2. Bhora resimbi rakagadzirwa neNo. 45 simbi yekugadzira inosangana ne "Technical Conditions for High-Quality Carbon Structural Steel" GB 699, uye simba regoho ndiro 360N / mm2.

3. Mabhaudhi ane simba repamusoro-soro emuchadenga anogadzirwa ne40Cr akadzimwa uye akadziya uye anopisa-kugadziriswa maererano ne "Technical Conditions of High-Quality Carbon Structural Steel" GB/T 16939.

4. Chisimbiso ndiro yemusoro wekoni inogadzirwa neQ235B simbi, uye musoro wekoni wakagadzirwa nefogi.Iyo dhayamita yemukati yekasiM33 inotora Q355B.

5. Iyo nzungu isina tambo yakagadzirwa neQ235B simbi yekugadzira.Kana dhayamita yemabhaudhi akasimba ari> M30, shandisa 45-gauge forgings yesimbi.

6. Zvisungo zvekusungirira zvinogadzirwa ne40Cr iyo yakadzimwa uye yakadzimwa.

7. Q235B simbi inoshandiswa pakutsigira, yakavharidzirwa ndiro, tsigiro uye zvikamu zvayo zvinobatanidza.

8. Mapurini anogadzirwa nesimbi inotonhora-yakaumbwa yakatetepa-yakagadzirwa nesimbi yeQ235B.

9. Mabhoti akajairika anogadzirwa neC-grade mabhoti akagadzirwa neQ235 simbi inosangana nezvinodiwa zvemazuva ano enyika, uye giredhi rekuita 4.8.

10. Magiredhi esimbi ataurwa pamusoro apa anofanirwa kunge aine zvitupa zvemhando yepamusoro uye mishumo yekuongororazve, zvinoenderana nezvinodiwa zvemazuva ano yenyika.

.Welding pakati Q235B simbi inotora E43 akatevedzana maelectrodes.

12. Chiyero chechiyero chakayerwa chesimba regoho kune kuyerwa kwehuwandu hwekusimba kwesimba resimbi haifaniri kunge yakakura kudarika 0.85.

13. Simbi inofanira kuva nematanho akajeka ekubereka, uye elongation haifaniri kunge iri pasi pe20%.

14. Simbi inofanira kuva ne weldability yakanaka uye inokwanisa kukanganisa kuoma.Kana iri Q235B simbi, chiyero chayo chemhando inofanirwa kuenderana ne "Carbon Structural Steel" (GB700-88), uye kana iri Q355B, chiyero chayo chemhando inofanirwa kuenderana ne "Low Alloy High Strength Structural Steel" GB/T1491, masimbi ese anofanira Iva netensile simba Kufanirwa vimbiso yesimba, kurebesa, simba regoho, inotonhora yekukotama bvunzo uye kabhoni, sarufa uye phosphorus zvemukati.Iyo welded chimiro zvakare ichave inokwanisa vimbiso yekabhoni yemukati.
