Amashejuli amapayipi abonisa ukujiya kodonga kanye nemikhawulo yokucindezela. Inombolo ngayinye imelela ukujiya kodonga oluthile. Onjiniyela basebenzisa lezi zinombolo ukuklama izinhlelo zamapayipi eziphephile nezisebenzayo.
IShejuli 40 inezindonga ezincane kuneShejuli 80. Ifanela izinhlelo ezinengcindezi ephakathi nendawo.
Izindonga zeShejuli 80 zijiyile kuneShejuli 40. Ziphatha ukucindezela okuphezulu futhi zihlala isikhathi eside. Ukukhetha ishejuli efanele kuvimbela ukuvuza, ukuqhuma, kanye nokwehluleka kusenesikhathi.
Ubukhulu bodonga buthinta amandla, ukugeleza, kanye nokufakwa. Amapayipi anobubanzi obufanayo kodwa amashejuli ahlukene asebenza ngendlela ehlukile.
Ipayipi le-SCH 40 linesisindo esilula, okwenza kube lula ukuphatha nokufaka. Liphinde linciphise isikhathi sokufaka.
Ipayipi le-SCH 80 linikeza amandla amakhulu, yize ubukhulu balo bodonga obukhulayo bubangela isisindo esikhulu. Ukusekelwa okufanele kanye nokuphathwa ngokucophelela kuyadingeka ukuze kugwenywe umonakalo.
Ukukhethwa kwamapayipi ensimbi yekhabhoni kumele kucabangele uhlobo loketshezi kanye nezidingo zesistimu. Imigqa yamapayipi okuhambisa amanzi, izinhlelo ze-HVAC, kanye namanethiwekhi okukhipha amanzi ngokuvamile kuncike kumapayipi e-SCH 40.
Ilinganisa izindleko, isisindo, kanye nomthamo wokucindezela. Amapayipi amakhemikhali, imigqa yomusi yezimboni, kanye nezinhlelo zamapayipi anomfutho ophezulu ziyazuza kumapayipi e-SCH 80. Izindonga zawo ezijiyile ziyamelana nokuguguleka, ukugqwala, kanye nokucindezeleka kwemishini.
Lapho kusetshenziswa khona i-SCH 40 kanye ne-SCH 80
Ipayipi le-Schedule 40 livame ukusetshenziswa ezindaweni zokuhlala, zezentengiselwano, kanye nezimboni ezilula. Isisindo esiphansi kakhulu sepayipi le-SCH 40 senza liphatheke kalula ngesikhathi sokuthutha nokufakwa. Ubukhulu balo bodonga busekela ingcindezi ephansi kuya kwephakathi ngenkathi lihlala liphatheka kalula uma lifakwa.
Onjiniyela abaningi bakhetha ipayipi le-SCH 80 lezitshalo zamakhemikhali, amapayipi anomfutho ophezulu, kanye nezinhlelo zezimboni. Limelana nokuguguleka, ukugqwala, kanye nomfutho omkhulu. Ukuthuthwa ngomusi, imigqa yamakhemikhali, kanye namapayipi amabanga amade kuvame ukukhetha i-SCH 80 ukuze kutholakale ukuthembeka.
Izinga lokushisa, uhlobo loketshezi, kanye nokucindezela kuthinta ukukhetha kwesheduli. Izintambo zomusi oshisayo zivame ukusebenzisa ipayipi le-SCH 80 ukuvimbela ukuguguleka. Izintambo zombhobho wamanzi abandayo zingasebenzisa ngokuphephile ipayipi le-SCH 40.
Ukukhethwa kwezinto nakho kubalulekile. I-SCH 80 yensimbi engagqwali inikeza ukumelana nokugqwala okwengeziwe ngenkathi igcina ubuqotho bengcindezi. Ukuhlela kahle kunciphisa izindleko zokulungisa futhi kwandise impilo yesevisi yezinhlelo zamapayipi.
Izinga lokugeleza kanye nobubanzi bangaphakathi yizinto ezibalulekile okufanele uzicabangele. Umklamo wodonga oluncane lwe-Sceedule 40 Carbon Steel Pipe unikeza ububanzi obukhulu bangaphakathi, okuvumela amandla aphezulu okugeleza. Ipayipi le-Schedule 80 linciphisa ububanzi bangaphakathi kancane, okuthinta ijubane loketshezi.
Onjiniyela babala ukwehla kwengcindezi kanye nokusebenza kahle kokugeleza kwesicelo ngasinye. Ukukhetha ishejuli efanele yepayipi kusiza ukuqinisekisa ukusebenza okuzinzile. Kuphinde kusekele amazinga okuphepha futhi konga izindleko ezinhlelweni ze-HVAC, ukuhlinzekwa kwamanzi, kanye namapayipi amakhemikhali.
Ukuqhathanisa i-SCH 40 ne-SCH 80
Ubukhulu bodonga yibo umehluko omkhulu. Izindonga ze-SCH 80 zijiyile, zinikeza ukubekezelelana okuphezulu kokucindezela kanye nokuqina. Izindonga ezijiyile zinciphisa kancane ububanzi bangaphakathi, zithinte ukugeleza.
Ipayipi le-SCH 40 elingamasentimitha angu-2 livame ukuphatha cishe ama-psi angu-280. Ipayipi le-SCH 80 elilingana nalo lisekela ama-psi angu-400. Ipayipi le-SCH 80 linesisindo esiphezulu futhi ngokuvamile lihilela izindleko ezinkulu zezinto zokwakha.
Ukufakwa kudinga izisekelo eziqinile. Izisekelo zilandela imithetho efanayo yesheduli. Izisekelo zamapayipi ezenziwe ngokwezindinganiso ze-SCH 80 zisekela ukucindezeleka okuphezulu kokusebenza.
Zombili izinhlelo ziza ngensimbi yekhabhoni, ipayipi lensimbi engagqwali, kanye nepayipi le-PVC. Ukukhetha inhlanganisela efanele kuqinisekisa ukuphepha, ukuthembeka, kanye nokuhambisana nezindinganiso zezimboni.
Izidingo zokuhlola nazo ziyahluka. Izinhlelo zamapayipi eShejuli 80 zenzelwe ukusebenza isikhathi eside ngemvamisa yokuhlolwa ephansi. Ipayipi le-SCH 40 lingadinga ukuhlolwa okuvamile ezimweni ezinzima. Onjiniyela bacabangela lezi zici lapho behlela amashejuli okulungisa kanye nezindleko zomjikelezo wokuphila.
Amathiphu Okufaka
Ipayipi le-Schedule 40 kulula ukulisika, ukulihlanganisa, nokusekela ngoba lilula. Ipayipi le-Howevr SCH 80 lidinga amathuluzi akhethekile okusika nokushisela.
Ukuqondana okufanele kanye nokusekelwa kuvimbela ukugoba noma amaphuzu okucindezeleka. Ukwandiswa kokushisa kuyinto ebalulekile okufanele icatshangelwe. Ipayipi le-SCH 80 liyamelana nokuguquguquka ngaphansi kokushisa, kodwa amalunga okunweba angase adingeke.
Ukufakwa kahle kuthuthukisa ukuphepha kohlelo. Kusiza ekwandiseni impilo yesevisi iyonke yohlelo. Ukuthuthwa koketshezi kuhlala kuzinzile ekuhlinzekweni kwamanzi, i-HVAC, kanye nezinhlelo zamapayipi amakhemikhali.
