Ipayipi Lensimbi Eligoqiwe Elingenamthungo
Amashubhu ensimbi angenamthungo ashisayo agingqiwe ngokuvamile akhiqizwa kumayunithi okugingqa amapayipi.
Ishubhu elingenalutho elingenalutho liyahlolwa futhi amaphutha angaphezulu ayasuswa, anqunywe ubude obudingekayo, agxile ekugcineni kwe-perforated ye-tube engenalutho, bese ithunyelwa esithandweni sokushisa ukuze kushiswe nokubhoboza umshini wokubhoboza.Iyaqhubeka nokujikeleza futhi iqhubekele phambili ngesikhathi sokubhoboza izimbobo.Ngaphansi kwethonya lama-roller kanye nokuphela, i-tube blank ingenalutho kancane kancane, ebizwa ngokuthi i-gross pipe.Bese ithunyelwa emshinini wokugoqa wamapayipi ozenzakalelayo ukuze uqhubeke nokugoqeka.Ekugcineni, ubukhulu bodonga bulinganiswe ngomshini wokulinganisa, futhi ububanzi bunqunywa umshini wokulinganisa ukuze uhlangabezane nezidingo zokucaciswa.Ukusetshenziswa kwamapayipi okugingqika okuqhubekayo ukukhiqiza amapayipi ensimbi angenamthungo ashisayo kuyindlela ethuthuke kakhulu.
Ipayipi lensimbi eligoqiwe elingenamthungo elishisayo: ishubhu eliyindilinga alinalutho → ukushisisa → ukubhobozwa → ukugoqeka okuphambanayo kwamaroll amathathu, ukugoqeka okuqhubekayo noma okuphumayo → ukususwa kweshubhu → ukuncishiswa kosayizi (noma ukuncishiswa kobubanzi) → ukupholisa → ishubhu le-billet → ukuqondisa → ukuhlolwa komfutho we-hydraulic (noma ukutholwa kwamaphutha) →maka→inqolobane
