I-tube eqhubekayo eqhubekayo (kwalapha kubhekiselwa kunqubo ye-MPM) i-mandrel isho ukugqoka ikholomu ende ye-capillary ngokuqhubekayo ngokusebenzisa i-chungechunge le-rack rack, ukugoqa kanye nokugoqa indlela kuvumelana ukuze kube izidingo zosayizi wepayipi lomama. Isici saso esihlukanisayo yisitha esikhulu, ukusebenza kahle kakhulu, ubude obungenalutho bepayipi elingenalutho kanye nekhwalithi yomkhiqizo, uhla olukhulu; Kepha ubuchwepheshe bayo obukhulu nobuchwepheshe obuhlobene nokulawula okuzenzakalelayo okufunwa kakhulu.
I-MPM Rack yohlobo lwe-roll-roll, isakhiwo esilingana kakhulu nesigayo esivamile sokugoqa. Kuya ngokunyakaza kweMandrel MPM kungahlukaniswa kube yi-Stopler-Stopper Stopper Mandrel Dill izinhlobo ezintathu.
Ngo-1970 ngaphambi kokuthi i-MPM isebenzise umsebenzi we-mandrel ogcwele ngokugcwele. Ukusuka ePunch ukuze ungene eCapillary ngemuva komshini we-mandrel ogibele umshini wokugibela, ugoqele lapho kuphuma khona umshini wokudonsela emuva, bese ubuyela eMandrel Mill Reception ngemuva kokupholisa, faka umjikelezo olandelayo womsebenzi.
Ngo-1970s France ne-Italy bavele kwi-mandrel half stopper kanye nesivimba se-MPM. Ngamafuphi, lezi zindlela ezimbili zokusebenza emshinini we-mandrel tube rolling, zibolekwe endleleni ye-mandrel yokusebenza komshini wokugoqa ezintathu.
Ingxenye egcinwe indlela yokusebenza ye-mandrel yokusebenza, isezinhlelweni zokugoqa, ijubane lokunyakaza kweMandrel lilinganiselwe, umnikazi wamakhadi uMandrel uhlanganiswe ngejubane elingaphansi kwejubane lesisebenzi sokusebenza. I-mandrel indlela yokusebenza, ngaphandle kokuthi i-rolling, ijubane lokunyakaza i-mandrel lilinganiselwe, uthayi uqede ngemuva kokugoqa, i-mandrel ngumnikazi wamakhadi abuyiselwe esikhundleni sokuqala ukusebenza emsebenzini.
Eminyakeni yamuva nje, i-y-rest-roll mpm eboniswe i-PQF Mill, ilandele ubuchwepheshe obunciphisa izingxabano kusuka ku-roller yesibili kuya kwezinguquko ezintathu ze-roller, ukukhishwa kwemishini, ukubekezelela okuphezulu kodonga kanye nokuvuselelwa kodonga okubili. Inqubo yayo eqinile eqinile ingathuthukiswa ubukhulu bePipe Cross-Section, indawo ephansi ye-Flange noma i-Ben lin Wen punton emkhakheni wamapayipi amancane abiyelwe kanye nokugoqa ipayipi eliphakeme eliphakeme.
