Ngokwezindlela ezihlukene zokukhiqiza, ingahlukaniswa ngamashubhu agoqiwe ashisayo, amashubhu agoqiwe abandayo, amashubhu adonswa abandayo, amashubhu akhishwe, njll.

1.1.Okushisayoinsimbi engagqwali amapayipi Seamlessngokuvamile akhiqizwa ezigayweni eziginqikayo zamapayipi.Ishubhu eliqinile liyahlolwa futhi lihlanzwe amaphutha angaphezulu, lisikwe ubude obudingekayo, ligxile ekugcineni kwepayipi elinezimbobo, bese lithunyelwa esithandweni sokushisa ukuze lishise futhi libhoboze emshinini wokubhoboza.Lapho i-perforation iqhubeka nokujikeleza futhi iqhubekela phambili ngesikhathi esifanayo, ngaphansi kwesenzo se-roller kanye nepulaki, kancane kancane kwakheka umgodi ngaphakathi kweshubhu elingenalutho, elibizwa ngokuthi i-capillary tube.Bese ithunyelwa emshinini wokugaya ukuze uqhubeke uginqika.Ekugcineni, ugqinsi lonke lodonga lufaniswa iyunifomu yawo wonke umshini, futhi ububanzi bulinganiswa ngomshini wokulinganisa ukuze kuhlangatshezwane nokucaciswayo.Ukusetshenziswa kwezigayo eziqhubekayo zamashubhu ukukhiqiza amashubhu ensimbi angenamthungo ashisayo kuyindlela ethuthuke kakhulu.

1.2.Uma ufuna ukuthola amapayipi angenamthungo anosayizi omncane kanye nekhwalithi engcono, ukugoqa okubandayo, ukudweba okubandayo noma inhlanganisela yalezi zindlela ezimbili kufanele kusetshenziswe.Ukugoqa okubandayo kuvame ukwenziwa emshinini wokugingqa ophakeme kabili.Ipayipi lensimbi ligoqwe ngephasi elinyakaziswayo elakhiwe i-variable cross-section circular hole groove kanye nepulaki emile.Umdwebo obandayo uvame ukuqhutshwa emshinini wokudweba obandayo we-single-chain noma kabili we-0.5-100T.

1.3.Indlela ye-extrusion ukubeka ishubhu elishisayo lingenalutho kusilinda esivaliwe se-extrusion, futhi induku enembobo kanye nenduku ye-extrusion ihamba ndawonye ukuze ikhiphe ingxenye ekhishiwe yembobo encane yokufa.Le ndlela ingakhiqiza amapayipi ensimbi anama-diameter amancane.

Lolu hlobo lwamapayipi ensimbi lungahlukaniswa ngezigaba ezimbili: ipayipi lensimbi engenamthungo kanye nepayipi lensimbi engagqwali elishiselwe (ipayipi lomthungo).Ngokusho kwenqubo yokukhiqiza ehlukene, ingaba: i-hot-rolled, extruded, idonswe ukubanda kanye ne-cold-rolled.Ukuma kungahlukaniswa ngamapayipi ayindilinga namapayipi amise okukhethekile.Amapayipi ensimbi ayindilinga asetshenziswa kakhulu, kodwa akhona namapayipi ensimbi engagqwali amise okukhethekile anjengesikwele, unxande, isemicircular, hexagonal, unxantathu oequilateral, kanye ne-octagonal.

Kumapayipi ensimbi angaphansi kwengcindezi yoketshezi, ukuhlolwa kwe-hydraulic kufanele kwenziwe ukuze kuqinisekiswe ukumelana nengcindezi kanye nekhwalithi, futhi akukho ukuvuza, ukumanzisa, noma ukwanda ngaphansi kwengcindezi eshiwo ofanelekile, futhi amanye amapayipi ensimbi nawo angaphansi kokuhlolwa kwe-crimping ngokuya ngezindinganiso. noma izidingo zomthengi.ukuhlolwa kwe-flaring, ukuhlolwa kokunciphisa.

Amapayipi ensimbi engenamthungo, abuye abizwe ngokuthi amapayipi ensimbi engenamthungo, enziwe ngezinsimbi zensimbi noma izimbobo zamashubhu aqinile abhodlozwe abe amashubhu e-capillary, abese enziwa ngokugingqika okushisayo, ukugoqeka okubandayo, noma umdwebo obandayo.Ukucaciswa kwamapayipi ensimbi angenamthungo kuvezwa ngamamilimitha obubanzi obungaphandle * Ukujiya kwezindonga
