Ipayipi lensimbi elingenamthungo lingenye yezinhlobo ezivame ukusetshenziswa kakhulu zamapayipi ensimbi angenamthungo.Ipayipi lensimbi elingenamthungo linengxenye engenalutho futhi alinawo amashisela kusukela ekuqaleni kuya ekugcineni.Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi engenamthungo linesisindo esilula uma ukugoba namandla e-torsion kufana, futhi kuwuhlobo lwensimbi eyongayo ye-cross-section.
Kunezinhlobo ezimbili eziyisisekelo zamapayipi ensimbi angenamthungo:
Cold drawn seamless (CDS) and hot rolled seamless (HFS).Womabili amapayipi ensimbi e-CDS ne-HFS anamandla nokuhlala isikhathi eside, kodwa izinzuzo zenqubo yokukhiqiza zohlobo ngalunye lwepayipi zihluke kancane.Ukunquma ukuthi ipayipi elibandayo elidonsayo elingenamthungo noma ipayipi elingenamthungo elishisayo elicutshungulwayo lingcono kakhulu kuncike ekutheni uhlela ukulisebenzisa kanjani ipayipi ohlelweni lwakho lokusebenza.
Ishubhu lemishini engenamthungo elidonsayo elibandayo lenziwe ngensimbi ye-carbon rolling eyi-SAE 1018 bese yelulelwa ekamelweni lokushisa.Phakathi nenqubo yokwelula, isihloko se-tube sidlula isikhunta.Amandla asetshenziselwa ukwelula insimbi ekugqineni nasekubunjweni okudingekayo futhi bushelelezi indawo.Lolu hlobo lwepayipi yensimbi luhlangana ne-ASTM A519 ejwayelekile.Inikeza amandla aphezulu okukhiqiza, ukubekezelelana okuseduze kanye nezindawo ezibushelelezi, okwenza kube yisinqumo sokuqala sezinhlelo zokusebenza eziningi zemishini.
Izinzuzo ze-cold drawn seamless (CDS):
Indawo enhle yokuqeda-i-machinability ehamba phambili-ukukhula kokubekezelela kobukhulu-amandla aphezulu kuya kwesisindo.Ishubhu yemishini engenamthungo ephethwe ukushisa ikhiqizwa kusetshenziswa i-SEA 1026 carbon steel futhi yenziwa kusetshenziswa inqubo efanayo yokukhipha, kodwa asikho isinyathelo sokugcina sokudweba ishubhu ekamelweni lokushisa.Amapayipi ensimbi akhiqizwa inqubo ye-HFS kulula ukusetshenzwa futhi alungele izinhlelo zokusebenza ezingadingi ukubekezelelana okuqinile kwe-dimensional noma isiphetho esibushelelezi.Ipayipi lensimbi le-HFS lihlangabezana nezinga le-ASTM A519 futhi livame ukusetshenziswa ezinhlelweni ezidinga izindonga eziqinile nezisindayo.
Izinzuzo ze-thermally processed seamless (HFS):
Okungabizi kakhulu-okuhle ukucutshungulwa-ububanzi bebanga losayizi.Amapayipi ensimbi akhiwe ngendlela ebandayo adonswa ngaphandle komthungo futhi ashise aqedelwe akhiwe yi-ASTM A519 ayatholakala ekucushweni okuhlukahlukene.
