Ipayipi lensimbi elingenamthungo elingu-20# livame ukusebenzisa insimbi yekhabhoni esezingeni eliphezulu engu-20# njengezinto zokusetshenziswa, okuyipayipi lensimbi elingenamthungo elingamelana nokushisa kwekhabhoni elisezingeni eliphezulu elivame ukusetshenziswa ezakhiweni zokwakha kanye nezakhiwo zemishini.

Insimbi engu-20# inezici ezilandelayo: ukuqina okuhle kanye nokushibilika okuqinile. Ngenxa yamandla ayo aphansi, ifaneleka ekucutshungulweni okubandayo kanye nasezindaweni ezingenamandla aphezulu.

Ipayipi lensimbi elingenamthungo elingu-20# lingasetshenziswa kule mboni elandelayo:

1. Kumapayipi ebhoyila anomfutho ophansi nophakathi, indinganiso yokusebenzisa iwukubaI-GB 3087, esetshenziselwa ukukhiqiza amashubhu e-superheater namashubhu odonga apholile ngamanzi ama-boilers anomfutho ophakathi nophansi (umfutho osebenzayo ≤5.9 MPa), asezingeni lokushisa eliphezulu (≤480℃) + indawo yokuxiliswa komusi wamanzi isikhathi eside

2. Amapayipi okuqhekeka kwephethiloli, indinganiso yokusebenzisa iyiI-GB 9948, esetshenziselwa ama-reactor, ama-heat exchanger, njll. amayunithi okuhlanza uphethiloli, ukuxhumana ne-acidic media (H₂S, CO₂) kanye nomfutho ophezulu (kufika ku-15 MPa)

3. Imishini yomanyolo enomfutho ophezulu, indinganiso yokusetshenziswaI-GB 6479, esetshenziselwa imishini yomanyolo enomfutho ophezulu (10~32 MPa) njenge-ammonia yokwenziwa kanye ne-urea, ethinta imithombo egqwala kakhulu (njenge-ammonia ewuketshezi, i-urea melt)

Amapayipi ensimbi angenamthungo ashiswayo asekela amanzi, indinganiso yokusebenzisa iwukubaGB/T17396, esetshenziselwa amakholomu okusekela amanzi kanye nama-jack ezimayini zamalahle, futhi imelana nemithwalo eshintshashintshayo ephindaphindwayo (50~100 MPa) kanye nokudlidliza komthelela
