Pombi yesimbi isina musono ine #20 inowanzo shandisa simbi yekabhoni yemhando yepamusoro ine #20 sezvinhu zvakabikwa, inova pombi yesimbi isina musono inodzivirirwa nekupisa nekabhoni yemhando yepamusoro inowanzoshandiswa muzvivakwa zvekuvaka nezvivakwa zvemakanika.

Simbi ye20# ine hunhu hunotevera: purasitiki yakanaka uye inogona kusungirirwa zvakasimba. Nekuda kwesimba rayo shoma, yakakodzera kugadzirwa muchando uye munzvimbo dzisina simba rakawanda.

Mapaipi esimbi asina musono ane 20# anogona kushandiswa mumaindasitiri anotevera:

1. Pamapaipi ebhoira ane simba rakaderera nerepakati, mwero wekushandisa ndeuyuGB 3087, inoshandiswa kugadzira machubhu esuperheater nemachubhu emadziro anotonhorerwa nemvura emaboilers ane pressure yepakati nepasi (kushanda kwepressure ≤5.9 MPa), ayo ari mukupisa kwakanyanya (≤480℃) + nzvimbo yekuoxidation yemvura kwenguva yakareba.

2. Mapaipi ekubvisa peturu, mwero wekushandisa ndiwoGB 9948, inoshandiswa pamagetsi ekugadzirisa zvinhu, ma "heat exchangers", nezvimwewo zve "petroleum refinery units", "contact acidic media" (H₂S, CO₂) uye "high pressure" (kusvika ku15 MPa)

3. Midziyo yefetereza ine simba guru, chiyero chekushandisa ndichoGB 6479, inoshandiswa pakushandisa fetereza ine simba guru (10~32 MPa) yakaita seammonia yakagadzirwa uye urea, inosangana nemidziyo inoparadza zvakanyanya (yakadai seammonia yemvura, urea melt)

Mapaipi esimbi asina musono anopfurwa nekupisa ekutsigira hydraulic, chiyero chekushandisa ndeichiGB/T17396, inoshandiswa pakutsigira makoramu nemajeki ehydraulic mumigodhi yemarasha, uye inotsungirira mitoro inochinjika-chinjika ine mafrequency akawanda (50~100 MPa) uye kudengenyeka kwesimba.
