20# seamless simbi pombi inowanzo shandisa 20# yemhando yepamusoro kabhoni simbi seyakabikwa, inova yemhando yepamusoro kabhoni inopisa-inodzivirira seamless simbi pombi inowanzoshandiswa mukuvaka zvivakwa uye michina zvimiro.

20 # simbi ine zvinotevera maitiro: yakanaka plasticity uye simba weldability. Pamusana pesimba rayo rakaderera, inokodzera kutonhora kushandiswa uye kwete-yakakwirira-yakasimba mifananidzo.

20 # isina musono simbi pombi inogona kushandiswa mune zvinotevera maindasitiri:

1. Kune yakaderera uye yepakati kudzvanywa boiler mapaipi, chiyero chekushandisa chiriGB 3087, inoshandiswa kugadzira machubhu epamusoro-soro uye machubhu emadziro anotonhorera emvura epakati uye akaderera mabhailers (kushanda kudzvanywa ≤5.9 MPa), ari mukupisa kwakanyanya (≤480 ℃) + mvura mhute oxidation nharaunda kwenguva yakareba.

2. Petroleum fracturing pombi, chiyero chekushandiswa ndichoGB 9948, inoshandiswa kumagetsi, magetsi ekupisa, nezvimwewo zve petroleum refining units, kubata acidic media (H₂S, CO₂) uye high pressure (kusvika ku15 MPa)

3. High-pressure fetireza midziyo, chiyero chekushandisa chiriGB 6479, inoshandiswa kune yakakwirira-pressure (10 ~ 32 MPa) fetiraiza zvishandiso senge synthetic ammonia uye urea, inobata midhiya inoparadza zvakanyanya (senge liquid ammonia, urea melt)

Kupisa-yakatenderedzwa seamless simbi mapaipi e hydraulic inotsigira, chiyero chekushandisa chiriGB/T17396, inoshandiswa kune hydraulic tsigiro makoramu uye jacks mumigodhi yemarasha, uye inomira yakakwira-frequency alternating mitoro (50 ~ 100 MPa) uye kukanganisa vibration.
