Ukukhetha ububanzi obufanele bangaphandle bamapayipi ensimbi angu-300 kubalulekile ekuqhubekeleni phambili okushelelayo kwemiklamo yobunjiniyela. Ukukhethwa kobubanzi obungaphandle bamapayipi ensimbi angu-300 kuhilela izici eziningi ezifana nokuphepha, umthamo wokuthwala umthwalo, nomthelela wokusetshenziswa kwephrojekthi. Ngakho-ke, izici ezihlukahlukene kudingeka zicatshangelwe ngokucophelela ukuze wenze isinqumo esihlakaniphile.

Okokuqala, qonda ububanzi bobubanzi bangaphandle bamapayipi ensimbi angu-300
Ububanzi bangaphandle bamapayipi ensimbi angu-300 ngokuvamile bubhekisela ebangeni ukusuka ngaphandle kodonga lwamapayipi ukuya ngaphandle kodonga lwamapayipi. Kuningi okucaciswayo okujwayelekile ongakhetha kukho, okufana no-Φ48, Φ60, Φ89, njll. Uma ukhetha ububanzi bangaphandle bamapayipi ensimbi angu-300, kufanele uqale uqonde ububanzi bobubanzi obuthile bangaphandle ukuze ukwazi ukukhetha ngendlela efanele. iphrojekthi.

Okwesibili, thola usayizi wobubanzi bangaphandle ngokwezidingo zobunjiniyela
1. Izidingo zomthamo wokuthwala umthwalo: Uma ipayipi lensimbi engu-300 lidinga ukuthwala isisindo esikhulu noma lidlale indima esekelayo, udinga ukukhetha ukucaciswa kwedayamitha enkulu yangaphandle ukuze uqinisekise ukuthi linomthamo owanele wokuthwala.
2. Imikhawulo yesikhala: Kwezinye izimo ezikhethekile zobunjiniyela, kungase kube nemikhawulo endaweni yokufaka ipayipi. Ngalesi sikhathi, udinga ukukhetha usayizi we-diameter yangaphandle ngokusho kwesimo sangempela ukuze uqinisekise ukufakwa okubushelelezi kwepayipi.
3. Izidingo zokuthutha okuwuketshezi: Uma ipayipi lensimbi engu-300 lisetshenziselwa ukuthutha uketshezi, kuyadingeka ukucabangela izinga lokugeleza nezinga lokugeleza koketshezi bese ukhetha usayizi ofanelekile wobubanzi bangaphandle ukuze kuncishiswe ukumelana nokuthuthwa koketshezi futhi kuthuthukiswe ukusebenza kahle kwezokuthutha.

Okwesithathu, bheka izindinganiso ezifanele kanye nemininingwane
Uma ukhetha ububanzi obungaphandle bepayipi lensimbi elingu-300, ungabhekisela kumazinga kazwelonke, ukucaciswa komkhakha, kanye nokucaciswa komklamo wobunjiniyela. Le mibhalo ivame ukunikeza iziphakamiso zokusetshenziswa kwamapayipi ensimbi okucaciswa okuhlukile ezimweni ezihlukene, ezingasetshenziswa njengereferensi yokukhetha ububanzi obungaphandle.

Okwesine, thintana nochwepheshe
Uma unokungabaza lapho ukhetha ububanzi bangaphandle bepayipi lensimbi engu-300, ungathintana nonjiniyela abafanelekile noma ochwepheshe bensimbi. Bazonikeza iziphakamiso ezinengqondo ezisekelwe ezimweni zangempela nolwazi ukuze basisize senze izinqumo ezingcono.

Okwesihlanu, cabangela umnotho kanye nokusebenza
Uma ukhetha ububanzi obungaphandle bepayipi yensimbi engu-300, ngaphezu kokucabangela izidingo zayo zokusebenza, udinga futhi ukucabangela umnotho wayo nokusebenza kwayo. Ngakolunye uhlangothi, qinisekisa ukuthi ububanzi obukhethiwe obungaphandle bungakwazi ukuhlangabezana nezidingo zephrojekthi, futhi ngakolunye uhlangothi, zama ukulondoloza izindleko futhi ugweme ukumosha izinsiza.
