Q235A ipuleti lensimbi

Ipuleti yensimbi ye-boiler isetshenziswa ikakhulukazi ekwenzeni ama-boilers ahlukahlukene kanye nezesekeli ezibalulekile. Njengoba ipuleti yensimbi ye-boiler isebenza ekushiseni okuphakathi (ngaphansi kuka-350 ° C) nokucindezela okuphezulu, ngaphezu kokucindezela okukhulu, iphinde ibe nomthelela, umthwalo wokukhathala kanye nokugqwala komhwamuko wamanzi. Kudingeka ukuqinisekisa amandla athile, futhi ine-welding enhle nokusebenza kokugoba okubandayo. Amabanga ajwayelekile: Q245R, A5155 grade 55, A5156 grade 60, Q235A carbon steel plate, A5166 grade 65, A51670 grade.

Ukwelulwa kwensimbi eqinile yealloy ephansi kungu-15% -23%, futhi amandla okumunca umthelela ekamelweni lokushisa mkhulu kuno-34J. I-Q235A carbon steel plate, ingxubevange ephansi yensimbi enamandla amakhulu inepulasitiki enhle kanye nokumelana nomthelela, okungagwema ukuphuka okuphukayo ngesikhathi somthelela futhi kwenze ukugoba okubandayo nokushisela kube lula. Ukwengeza, izinga lokushisa lokushintsha eliphukile lensimbi ephansi ye-alloy high-strength liphansi, futhi inani lokusebenza lokumuncwa kwensimbi ye-E-grade ku -40 ° C alikho ngaphansi kuka-27J. Lokhu kubaluleke kakhulu ezingxenyeni zobunjiniyela kanye nezinto zokuhamba njengezimoto, imikhumbi, amapulatifomu kawoyela aphesheya kwezilwandle, iziqukathi, amabhuloho, njll.
