Ukukhethwa kwezinto ezibonakalayo kwamakhabethe okulawula kuthinta ngokuqondile ukuvikelwa kwawo, ukuqina, nezimo ezisebenzayo. Ahlukaniswa ngokuyinhloko ngezigaba ezilandelayo:
1. Insimbi
- Insimbi engagqwali: I-Corrosion-iyamelana ne-oxidation-iyamelana ne-oxidation, ifanele izindawo ezinomswakama, izimboni zamakhemikhali, noma ukucubungula ukudla, kodwa ngezindleko eziphezulu.
- Insimbi ye-Carbon: Ezomnotho nokusebenzayo, enamandla amakhulu okusebenza, idinga ukwelashwa okungaphezulu (okufana nokufuthwa kwepulasitiki) ukuze kuvinjwe ukugqwala futhi isetshenziswa kakhulu ezindaweni zezimboni.
- Ingxubevange ye-Aluminium: Ilula futhi inokukhipha ukushisa okuhle, ilungele amadivayisi eselula noma{1}}izindawo ezinezinga lokushisa eliphezulu, kodwa inikeza ukuvikeleka okuncane kancane.
2. Amapulasitiki obunjiniyela
- I-ABS/i-polycarbonate: I-Insulation enhle kakhulu, i-lightweight, ne-chemical resistance, ifanele amalabhorethri, izikhungo zezokwelapha, noma ukusetshenziswa kwangaphandle (okudinga ukuvikeleka kwe-UV), kodwa okunokumelana nomthelela ophansi.
3. Izinto ezihlanganisiwe
- Okufana ne-fiberglass reinforced plastic (FRP), inikeza kokubili ukumelana nokugqwala namandla okusebenza, kodwa abiza kakhulu futhi avame ukusetshenziswa ezindaweni ezikhethekile (njengemikhumbi namakhemikhali e-petrochemical).
Imibandela Yokukhetha:
- Imvelo: Ukumelana nokugqwala kuyadingeka ukuze usetshenziswe ngaphandle (khetha insimbi engagqwali/FRP); ukushisisa ukushisa kuyadingeka-ezindaweni zokushisa eziphezulu (khetha ingxubevange ye-aluminium).
- Isilinganiso sokuvikela: Amakhabethe ensimbi anconyelwe i-IP54 nangaphezulu, kuyilapho amakhabethe epulasitiki avaliwe ayinketho ye-IP65. Izindleko: I-Carbon steel inikeza inani elingcono kakhulu lemali, kuyilapho insimbi engagqwali nezinto eziyinhlanganisela zifaneleka{3}}ukuqina kwesikhathi eside.
Ngaphezu kwalokho, indlela yokukhweza (udonga-okukhwezwayo, okuphansi{1}}okumile) kanye nezidingo zokuvikela kazibuthe kagesi (isb., amakhabethe ensimbi angavikela ukuphazamiseka) nazo kufanele zicatshangelwe.
