Kungani iningiamapayipi ensimbiAmamitha ayi-6 ngengxenye ngayinye, kunokuba amamitha ayi-5 noma ayi-7?
Kuma-oda amaningi okuthengwa kwensimbi, sivame ukubona: “Ubude obujwayelekile bamapayipi ensimbi: amamitha ayi-6 ngengxenye ngayinye.”
Isibonelo, amapayipi ahlanganisiwe, amapayipi agqitshiwe, amapayipi ayisikwele nangunxande, amapayipi ensimbi angenamthungo, njll., asebenzisa kakhulu ubude obungu-6m njengobude obujwayelekile besiqephu esisodwa. Kungani kungabi amamitha ama-5 noma amamitha ayi-7? Lokhu akuyona nje "umkhuba" wemboni, kodwa kunalokho umphumela wezinto eziningi.
Amamitha ayi-6 yibanga "elingaguquki" lamapayipi amaningi ensimbi
Izindinganiso eziningi zensimbi zikazwelonke (isib. GB/T 3091, GB/T 6728, GB/T 8162, GB/T 8163) zichaza ngokusobala: Amapayipi ensimbi angakhiqizwa ngobude obungaguquki noma obungaguquki.
Ubude obujwayelekile obungaguquki: 6m ± ukubekezelelana. Lokhu kusho ukuthi amamitha ayi-6 ubude besisekelo obuqashelwa ezweni lonke futhi obuvame kakhulu.
Ukunqunywa Kwemishini Yokukhiqiza
Imigqa yokukhiqiza amapayipi ashiselwe, amayunithi okwenza amashubhu asikwele nakanxande, imishini yokudweba ebandayo, imishini yokuqondisa, kanye nezinhlelo zobude obungaguquki bepayipi elishiselwe ngokushisa—amamitha ayi-6 ubude obufanele kakhulu kuma-rolling mill amaningi kanye nemigqa yokwenza amapayipi ashiselwe. Futhi ubude obulula kakhulu ukulawula ukuze kukhiqizwe kahle. Ubude obedlulele bubangela: ukucindezeleka okungazinzile, ukujikijela/ukusika okunzima, kanye nokudlidliza komugqa wokucubungula. Ubude obufushane kakhulu buholela ekunciphiseni kokukhipha kanye nokwanda kwemfucuza.
Imikhawulo yezokuthutha
Amapayipi angamamitha ayi-6:
- Gwema imikhawulo yobukhulu obukhulu
- Susa izingozi zokuhamba
- Ungadingi izimvume ezikhethekile
- Lungisa ukulayisha/ukukhipha umthwalo
- Nikeza izindleko eziphansi kakhulu
Amapayipi angamamitha angu-7–8:
- Khulisa ubunzima bokuthutha
- Khulisa izingozi ezinkulu kakhulu
- Izindleko zezokuthutha zikhushulwa kakhulu
Amamitha ayi-6 alungele ukwakhiwa: imfucuza ephansi, ukusika okuqondile, kanye nezidingo ezivamile zesigaba ngemuva kokusika (3 m, 2 m, 1 m).
Izimo eziningi zokufakwa nokucubungula zidinga izingxenye zamapayipi eziphakathi kwamamitha angu-2-3.
Ubude obungamamitha ayi-6 bunganqunywa ngokunembile zibe izingxenye ezingama-2×3 m noma ezingama-3×2 m.
Ubude obungamamitha ama-5 buvame ukudinga ukunwetshwa okwengeziwe kokushisela kumaphrojekthi amaningi;
Ubude obungamamitha ayi-7 bunzima ekuthuthweni nasekuphakanyisweni, futhi buthambekele kakhulu ekugobeni.
Ubude obungamamitha ayi-6 baba yindinganiso evame kakhulu yamapayipi ensimbi ngoba ihlangabezana ngasikhathi sinye: amazinga kazwelonke, ukuhambisana kwemigqa yokukhiqiza, ukulula kwezokuthutha, ukusebenza kahle kokwakha, ukusetshenziswa kwezinto, kanye nokunciphisa izindleko.
