Yethula:
Engxenyeni yamapayipi, abadlali ababili abakhulu, abangenamthungo nabashiselwe, bebebanga isikhundla esiphezulu.Nakuba zombili zisebenza ngokufanayo, zinezici ezihlukile ezizenza zifanelekele izinhlelo zokusebenza ezithile.Kule bhulogi, sihlola ama-nuancesipayipi elingenamthungo vs ipayipi elishiselwe, hlola ukuhluka kwazo kanye nezinhlelo zokusebenza, futhi ekugcineni zikusize uqonde ukuthi yiluphi uhlobo olulungele izidingo zakho.
Ipayipi elingenamthungo:
Ipayipi elingenamthungo, njengoba negama liphakamisa, ikhiqizwa ngaphandle kwamalungu ashiselwe noma imithungo.Zenziwa ngokukhipha i-cylindrical billet eqinile ngenduku enembobo ukuze zakhe ishubhu elingenalutho.Le nqubo yokukhiqiza iqinisekisa ukufana nokuvumelana esakhiweni samapayipi, okusivumela ukuthi simelane nezingcindezi eziphezulu namazinga okushisa.
Izinzuzo zamapayipi angenamthungo:
1. Amandla nokwethembeka:Amashubhu angenamthungo anamandla akhethekile nokwethembeka ngenxa yesilinganiso sawo sokucindezela kwangaphakathi futhi awekho amalunga ashiselwe.Le khwalithi izenza zilungele izinhlelo zokusebenza ezidinga izinga eliphezulu lokuqina, njengokuthuthwa kukawoyela negesi kanye nezinqubo zokucwenga.
2. Ubuhle:Amashubhu angenamthungo aziwa ngokubukeka kwawo okubushelelezi, okupholishelwe, okwenza kube ukukhetha okudumile kwezakhiwo zezakhiwo, izingxenye zezimoto, kanye nefenisha ephezulu.
3. Ukumelana nokugqwala:Amapayipi angenamthungo ngokuvamile abonisa ukumelana nokugqwala okuhle kakhulu, ikakhulukazi uma enziwe ngezinto ezifana nezingxube zensimbi engagqwali noma ingxubevange.Lesi sici sinenzuzo ezinhlelweni ezibandakanya ukuchayeka ezintweni ezonakalisayo noma izindawo ezinokhahlo.
Ipayipi elishiselwe:
Ngokungafani nepayipi elingenamthungo,ipayipi elishiselwekwakheka ngokugoqa umucu wensimbi oyisicaba ube yisimo esiyisilinda ngochungechunge lwamarola.Imiphetho ye-strip ibe isihlanganiswa ndawonye ngamasu okushisela ahlukahlukene njenge-electric resistance welding (ERW), i-longitudinal submerged arc welding (LSAW) noma i-helical submerged arc welding (HSAW).Inqubo yokushisela inikeza la mapayipi izici ezihlukene nezimfanelo.
Izinzuzo zamapayipi ashiselwe:
1. Ukusebenza kahle kwezindleko:Amapayipi ashiselwe ngokuvamile abiza kakhulu kunamapayipi angenamthungo, ikakhulukazi ngenxa yokusebenza kahle kanye nesivinini senqubo yokukhiqiza.Kanjalo, avame ukuthandwa ezinhlelweni lapho ukusebenza kahle kwezindleko kubaluleke kakhulu, njengamapayipi, uhlaka lwesakhiwo, kanye nokuthutha uketshezi olunomfutho ophansi.
2. Ukuhlukahluka:Amapayipi ashiselwe anokwehlukahlukana okukhulu ngobukhulu kanye nokuma njengoba angenziwa ezinhlobonhlobo zamadayamitha, ubude kanye nogqinsi.Lokhu kuvumelana nezimo kubenza bafanelekele uhla olubanzi lwezinhlelo zokusebenza kusuka kumapayipi amapayipi amancane kuya kwingqalasizinda yezimboni ezinkulu.
3. Ikhwalithi yokushisela ethuthukisiwe:Inqubo ye-welding esetshenziselwa ukujoyina imiphetho yamapayipi ithuthukisa amandla omthungo, iqinisekisa ukusebenza okuthembekile ngisho nangaphansi kwengcindezi ephakathi.Lesi sici senza ipayipi elishiselwe ukuthi lilungele izinhlelo zokusebenza ezibandakanya ukudluliswa koketshezi, ukwakhiwa, namapayipi ngaphakathi kwezakhiwo.
Ekuphetheni:
Ngakho-ke, yiluphi uhlobo lwamapayipi okufanele ukhethe?Impendulo ilele ekuqondeni izidingo ezithile zephrojekthi noma isicelo sakho.Amashubhu angenamthungo ahamba phambili ezindaweni ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu, kuyilapho amashubhu ashiselwe abiza kakhulu futhi aguquguquka.Yenza isinqumo esinolwazi ngokucabangela izici ezinjengamandla, ukuqina, izindleko, nezidingo zohlelo lokusebenza.
Khumbula, ipayipi elingenamthungo liwumfanekiso wamandla nokuthembeka, lilungele izinhlelo zokusebenza ezibucayi, kuyilapho ipayipi elishiselwe linikeza izixazululo ezingabizi kanye nokuzivumelanisa nezimo.Ekugcineni, uchwepheshe wemboni noma uchwepheshe kufanele kukhulunywe naye ukuze kunqunywe inketho evumelana kangcono nezidingo zakho ezithile futhi iqinisekise umphumela oyimpumelelo nosebenza kahle wephrojekthi yakho.
