Ikhwalithi ephezulu yensimbi ye-PTFE yokufakwa kwamapayipi anemigqa

Amapayipi ensimbi ane-PTFE anomugqa wensimbi ajabulela idumela elithi “Inkosi Yepulasitiki”, enezinga lokushisa elihle kakhulu futhi imelana nokugqwala, futhi ilungele ukudlulisa imidiya egqwalayo eqinile njenge-nitric acid, i-sulfuric acid, i-hydrofluoric acid, i-phosgene, i-chlorine, i-aqua regia, ama-acids axubile, ama-bromide nezinye izinyibilikisi eziphilayo. Steel lined PTFE amapayipi nokufakwa ezingasebenza stably emazingeni okushisa aphezulu (ngaphakathi 150 ° C) ngaphansi kwezimo ezimbi ngokwedlulele ingcindezi isikhathi eside baye baxazulula ukushiyeka okwedlule steel lined PTFE amapayipi kanye nokufakwa ezingakwazi ukumelana ingcindezi engemihle futhi asetshenziswa kabanzi ku distillation eziningi nezinye izinga lokushisa eliphezulu kanye high negative ingcindezi izinhlelo.

Ipayipi lensimbi elifakwe i-teflon push-pressure liwukucubungula kwemishini, uma kuqhathaniswa nobunye ubuchwepheshe bokucubungula ipayipi le-teflon elinensimbi, ipayipi le-teflon elinensimbi elikhiqiziwe linakho: ukuminyana okuphezulu, indawo ebushelelezi, ukushuba okufanayo nezinye izici. "Ukuminyana okuphezulu" kuvimbela i-medium ukuthi ingangeni futhi ayigogeki kalula ekusetshenzisweni; "indawo ebushelelezi" yenza ukumelana nokugeleza okuphakathi kube kuncane futhi kuvimbela ngokuphumelelayo ukunamathela; "ubukhulu obufanayo" benza ipayipi le-PTFE elifakwe kumugqa wensimbi libe namandla aphezulu nokusebenza okuhle kokuvala e-flange. Ifanele ukugxiliswa okuhlukahlukene kwama-asidi, ama-alkali, ama-oxidants aqinile, i-aqua regia nezinye imidiya ezonakalisayo.

Uma kuqhathaniswa namanye amapayipi ensimbi ane-Teflon anensimbi, amapayipi ensimbi ane-Teflon anezici ezilandelayo: ukuminyana okuphezulu, indawo ebushelelezi, ukushuba okufanayo, njll. "indawo ebushelelezi" yenza ukumelana nokugeleza okuphakathi kube kuncane futhi kuvimbela ngokuphumelelayo ukunamathela; "ubukhulu obufanayo" benza ipayipi le-PTFE elifakwe kumugqa wensimbi libe namandla aphezulu nokusebenza okuhle kokuvala e-flange. Ifanele ukugxiliswa okuhlukahlukene kwama-asidi, ama-alkali, ama-oxidants aqinile, i-aqua regia nezinye imidiya ezonakalisayo.

Ukujiya komugqa wamapayipi ane-fluorine
