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, ingxubevange. ama-acids, ama-bromides nezinye izincibilikisi eziphilayo.Steel lined PTFE amapayipi nokufakwa okungasebenza ngokuzinza emazingeni okushisa aphezulu (ngaphakathi 150 ° C) ngaphansi kwezimo zengcindezi embi ngokwedlulele isikhathi eside ziye zaxazulula ukushiyeka kwensimbi yangaphambilini efakwe amapayipi e-PTFE nokufakwa okungakwazi ukumelana nokucindezela okungalungile futhi asetshenziswa kabanzi eziningi ze-distillation nezinye izinga lokushisa eliphezulu kanye nezinhlelo zokucindezela okuphezulu okungalungile.

Ipayipi lensimbi elifakwe i-teflon push-pressure lisebenza ngomshini kuphela, uma liqhathaniswa 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.Ilungele ukugxiliswa okuhlukahlukene kwama-asidi, ama-alkali, ama-oxidants aqinile, i-aqua regia nezinye imidiya ezonakalisayo.

Uma kuqhathaniswa namanye amapayipi ensimbi e-Teflon anezinsimbi, 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
