2. Ukumelana nokugqwala okuqinile
I-ASTMA53GR.B ipayipi lensimbi engenamthungo lenziwe ngensimbi yesakhiwo sekhabhoni ephezulu.Ngemva kwenqubo eqinile yokwelapha ukushisa, inokumelana nokugqwala okuhle futhi ingamelana nokuguguleka kwamakhemikhali afana nama-asidi nama-alkali, iqinisekisa ukusebenza okuzinzile kwesikhathi eside kohlelo lwamapayipi.
3. Ukusebenza kahle kokucubungula
I-ASTMA53GR.B ipayipi lensimbi engenamthungo inokushisela okuhle, ukusika kanye nepulasitiki, okwenza kube lula ukucutshungulwa nokuyifaka.Ngaphezu kwalokho, impahla nayo inokumelana okuhle kokushisa okuphezulu nokuphansi futhi ingagcina ukusebenza okuzinzile ezindaweni ezinokhahlo.
Izinkambu zokufaka isicelo ze-ASTMA53GR.B ipayipi lensimbi engenamthungo
I-ASTMA53GR.B ipayipi lensimbi engenamthungo lisetshenziswa kakhulu emikhakheni yokuthutha kawoyela, igesi yemvelo, amanzi, umusi nezinye izinkambu.Ikakhulukazi kwezinye izikhathi ezidinga ukumelana nengcindezi ephezulu kanye nokushisa okuphezulu, lokhu okuqukethwe kuyisinqumo esibalulekile.Ngaphezu kwalokho, amapayipi ensimbi angenamthungo we-ASTMA53GR.B nawo asetshenziswa kakhulu kumakhemikhali, amandla kagesi, ezokwakha nezinye izimboni ukuze ahlinzeke ngezinto ezithembekile zamapayipi kumasistimu ahlukahlukene okulethwa koketshezi.
Ukukhethwa nokugcinwa kwepayipi lensimbi elingenamthungo le-ASTMA53GR.B
1. Izinyathelo zokuphepha lapho uthenga
Lapho uthenga ipayipi lensimbi elingenamthungo le-ASTMA53GR.B, kufanele unake amaphuzu alandelayo:
(1) Khetha abakhiqizi abajwayelekile ukuze baqinisekise ikhwalithi yomkhiqizo ethembekile;
(2) Hlola ukuthi ukucaciswa, ubukhulu nokuqina kodonga lwepayipi lensimbi kuyahlangabezana yini nezidingo;
(3) Hlola izinga eliphezulu lepayipi lensimbi ukuze uqiniseke ukuthi awekho amaphutha noma umonakalo osobala;
(4) Khetha izinto ezifanele zamapayipi ensimbi kanye nokucaciswa ngokuya ngendawo yokusetshenziswa kanye nezidingo.
2. Izinyathelo zokuphepha
Uma usebenzisa i-ASTMA53GR.B ipayipi lensimbi engenamthungo, kufanele unake amaphuzu alandelayo:
(1) Ahlole njalo futhi anakekele amapayipi ukuze abone futhi abhekane nezinkinga ngesikhathi;
(2) Gcina amapayipi ehlanzekile futhi omile ukuze agweme ukugqwala kwamapayipi ngaphakathi nangaphandle;
(3) Ngesikhathi sokuthutha nokufaka, kufanele kuqashelwe ukuvikela ipayipi ukuze kugwenywe ukushayisana nokulimala;
(4) Amapayipi ensimbi alimele kufanele ashintshwe futhi alungiswe kusenesikhathi ukuze kuqinisekiswe ukuphepha nokuzinza kohlelo lwamapayipi.
Ukufingqa, i-ASTMA53GR.B ipayipi lensimbi engenamthungo liwumsebenzi wamapayipi osebenza kahle kakhulu nezinkambu zohlelo olubanzi.Ngesikhathi sokusebenzisa, udinga ukunaka izindaba zokuthenga nokugcinwa ukuze uqinisekise ukuphepha nokuzinza kwesistimu yamapayipi.Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ipayipi lensimbi engenamthungo le-ASTMA53GR.B lizosetshenziswa emikhakheni eyengeziwe, okuletha ukunethezeka nezinzuzo ezengeziwe ekukhiqizweni nasekuphileni komuntu.
