1. Isingeniso Sokusekelwa Kwensimbi
Ukusekelwa kwensimbi iyingxenye yesakhiwo sensimbi esetshenziswa kakhulu, ikakhulukazi esetshenziselwa ukusekela nokuqinisa izakhiwo, imishini emikhulu nemishini, nezakhiwo zobunjiniyela. Isetshenziswe kabanzi emikhakheni yezokwakha, imishini, ugesi, imboni yamakhemikhali, i-petroleum, i-aerospace, njll.
2. Ithebula lesayizi lokusekela insimbi
Okulandelayo ithebula lesayizi lensimbi yokusekela, eliqukethe imingcele yesayizi yezisekelo zensimbi ezivamile, kanye nobubanzi obusebenzayo nezici eziyinhloko.
Ukucaciswa (iyunithi: mm) Ubude (L) Ububanzi (D) Ubukhulu bodonga (S) Ububanzi bohlelo lokusebenza Izici eziyinhloko
Ф8 1000 8 0.8 Izakhiwo, amabhuloho, njll. Ukunemba okuphezulu, amandla amahle kakhulu, afanele izikhathi ezihlukahlukene
Ф10 1500 10 1 Imishini, izinto zokusebenza, njll. Amandla aphezulu, ukumelana nokugqwala okuhle, kulungele olwandle, amakhemikhali nezinye izindawo
Ф12 2000 12 1.2 Uphethiloli, igesi yemvelo, njll. Ingagugi, imelana nokugqwala, impilo ende yesevisi, ifanele izindawo ezihlukahlukene ezinokhahlo.
Ф16 2500 16 1.5 Amandla kagesi, i-aerospace, njll. Umthamo wokuthwala onamandla, isakhiwo esihlangene, ukufakwa kalula
Ф20 3000 20 2 Amakhemikhali, imithi, njll. Ukumelana nokushisa okuhle, ukumelana nokugqwala okuhle, kulungele izinga lokushisa eliphezulu kanye nendawo yokucindezela okukhulu.
Ф25 3500 25 2.5 Ukuvikelwa kwemvelo, ukudla, njll. Ukuphepha kanye nenhlanzeko, kulungele izikhathi ezinezidingo eziphezulu zemvelo.
3. Izinyathelo zokuphepha zokuthenga izisekelo zensimbi
Lapho uthenga izisekelo zensimbi, izici ezilandelayo zidinga ukucatshangelwa:
1. Izisekelo zensimbi zokucaciswa okufanele kufanele zithengwe ngokuya ngendawo yokusetshenziswa kanye nezidingo zomthwalo.
2. Izisekelo zensimbi ezikhiqizwa abakhiqizi abajwayelekile kufanele zikhethwe ukuze kuqinisekiswe ikhwalithi yomkhiqizo.
3. Kuyadingeka ukunaka ukuthi ubude, ububanzi, ubukhulu bodonga kanye neminye imingcele yokusekelwa kwensimbi kuhlangabezana nezidingo.
4. Izinto ezisetshenziswayo ezifanele njenge-Q235B, Q345B, njll. kufanele zikhethelwe izinjongo nezindawo ezihlukene.
Ngamafuphi, njengengxenye ebalulekile yesakhiwo, ikhwalithi kanye nokucaciswa kwezisekelo zensimbi kubalulekile ekusebenzeni nasekuphepheni kwephrojekthi. Ithebula lesayizi elingenhla nezinyathelo zokuphepha zokuthenga ngezereferensi, futhi ngithemba ukuthi zingasiza abasebenzisi ukuthenga nokusebenzisa izisekelo zensimbi.
