Ukukhiqizwa kwamapayipi ensimbi anamandla aphezulu
Indlela yokukhiqiza yepayipi lensimbi engenamthungo ihlukaniswe cishe ngendlela yokugoqa (indlela ye-Mennesmann) kanye nendlela yokukhipha.Indlela ye-cross-rolling (indlela ye-Mennesmann) eyokuqala ibhoboze ishubhu elingenalutho nge-cross-roller, bese linwetshwa ngomshini wokugaya.Le ndlela inesivinini sokukhiqiza esisheshayo, kodwa idinga amandla aphezulu e-tube engenalutho, futhi ilungele ukukhiqizwa kwe-carbon steel kanye namashubhu ensimbi ane-alloy ephansi.
Indlela ye-extrusion iwukubhoboza ishubhu lingenalutho noma ingot ngomshini wokubhoboza, bese uyikhiphela epayipini lensimbi nge-extruder.Le ndlela ayisebenzi kahle kunendlela ye-skew rolling futhi ifaneleka ukukhiqizwa kwamapayipi ensimbi anamandla aphezulu.
Kokubili indlela yokugoqa i-skew kanye nendlela yokukhipha kufanele kuqale kushisise ishubhu lingenalutho noma i-ingot, futhi ishubhu lensimbi elikhiqiziwe libizwa ngokuthi ishubhu eligoqelwe ngokushisayo.Amapayipi ensimbi akhiqizwa izindlela zokusebenza ezishisayo ngezinye izikhathi angabanda njengoba kudingeka.
Kunezindlela ezimbili zokusebenza okubandayo: enye indlela yokudweba ebandayo, okuwukudweba ipayipi lensimbi ngomdwebo wokufa ukuze kancane kancane ube mncane futhi unwebe ipayipi lensimbi;
Enye indlela iyindlela yokugoqa ebandayo, okuyindlela yokusebenzisa umshini wokugaya oshisayo owasungulwa abakwaMennesmann Brothers ekusebenzeni okubandayo.Ukusebenza okubandayo kwepayipi lensimbi engenamthungo kungathuthukisa ukunemba kwe-dimensional kanye nokuqedwa kokucubungula kwepayipi lensimbi, futhi kuthuthukise izakhiwo zemishini zezinto.
Inqubo yokukhiqiza yepayipi lensimbi engenamthungo (ipayipi lensimbi eligoqiwe elishisayo)
Ukungenamthungo kwepayipi lensimbi kuqedwa ngokuyinhloko ukunciphisa ukungezwani, futhi inqubo yokunciphisa ukungezwani kuyinqubo eqhubekayo yokugingqa yensimbi eyisisekelo engenalutho ngaphandle kwe-mandrel.Ngaphansi kombandela wokuqinisekisa ikhwalithi yokushisela yepayipi elingumzali, inqubo yokunciphisa ukungezwani kwamapayipi okushisela iwukushisa ipayipi elishiselwe lilonke libe ngaphezu kwama-degree Celsius angu-950, bese liligoqa libe ngamadayimitha ahlukahlukene angaphandle nezindonga ngesinciphisi sokungezwani. ingqikithi yamaphasi angama-24 okunciphisa ukungezwani).Emapayipini aqediwe awugqinsi, amapayipi ensimbi agingqiwe ashisayo akhiqizwa yile nqubo ahluke kakhulu kumapayipi ashiselwe avamile anemvamisa ephezulu.Ukuginqika kwesibili kokunciphisa ukungezwani kanye nokulawula okuzenzakalelayo kwenza ukunemba kobukhulu bepayipi lensimbi (ikakhulukazi ukuzungeza nokunemba kodonga lomzimba wepayipi) kube ngcono kunamapayipi afanayo angenamthungo.
