①Ukubekezelela ububanzi bangaphandle
Ipayipi lensimbi elingenamthungo: Kusetshenziswa inqubo yokugoqa okushisayo, futhi ukulinganisa kuqedwa cishe ku-8000C. Ukwakheka kwempahla eluhlaza, izimo zokupholisa, nesimo sokupholisa samaroli wepayipi lensimbi kunomthelela omkhulu kububanzi bawo bangaphandle. Ngakho-ke, ukulawula ububanzi bangaphandle kunzima ukunemba nokuguquguquka. Ibanga elikhulu.
Ipayipi lensimbi le-ERW: lamukela ukugoba okubandayo nokulinganisa ngo-0.6% wokunciphisa ububanzi. Izinga lokushisa lenqubo lihlala lihlala ekamelweni lokushisa, ngakho ububanzi bangaphandle bulawulwa ngokunembile futhi ububanzi bokuguquguquka buncane, okuvumela ukuqedwa kwamabhakede amnyama;

②Ukubekezelela ukujiya kwezindonga
Ipayipi lensimbi elingenamthungo: Ikhiqizwe ukubhobozwa kwensimbi eyindilinga, ukuchezuka kokuqina kodonga kukhulu. Ukuginqika okushisayo okulandelayo kungaqeda kancane ukungalingani kodonga, kodwa okwamanje, amayunithi athuthuke kakhulu angakwazi ukukulawula kuphela ngaphakathi kuka-±5~10%t.
Ipayipi lensimbi le-ERW: amakhoyili agoqelwe ashisayo asetshenziswa njengezinto ezingavuthiwe, futhi ukubekezelela ukujiya kwemichilo yesimanje egoqwe ngokushisayo kungalawuleka ngaphakathi kuka-0.05mm.

③Ukubonakala
Ukukhubazeka kwangaphandle kwezikhala ezisetshenziswa emapayipini ensimbi angenamthungo akukwazi ukuqedwa ngenqubo yokugoqa okushisayo. Angapholishwa kuphela ngemva kokuba umkhiqizo oqediwe usuqediwe. Umzila ovunguzayo oshiywe ngemva kokubhobozwa ungasuswa kancane kuphela phakathi nenqubo yokunciphisa udonga.
Amapayipi ensimbi e-ERW asebenzisa amakhoyili ashisayo njengezinto ezingavuthiwe. Izinga eliphezulu lamakhoyili izinga eliphezulu lamapayipi ensimbi e-ERW. Izinga eliphezulu lamakhoyili ashisayo kulula ukuwalawula futhi anekhwalithi ephezulu. Ngakho-ke, izinga eliphezulu lamapayipi ensimbi e-ERW lingcono kakhulu kunamapayipi ensimbi angenamthungo.

④Ovality
Ipayipi lensimbi elingenamthungo: Ukusebenzisa inqubo yokugoqa okushisayo, ukwakheka kwempahla eluhlaza, izimo zokupholisa, nesimo sokupholisa samaroli konke kunomthelela omkhulu kububanzi obungaphandle bepayipi lensimbi. Ngakho-ke, ukulawulwa kobubanzi bangaphandle kunzima ukulawula ngokunembile, futhi ububanzi bokuguquguquka bukhulu.
Ipayipi lensimbi le-ERW: Lakhiwe ngokugoba okubandayo, ngakho ububanzi bangaphandle bulawulwa ngokunembile futhi ububanzi bokushintshashintsha buncane.

⑤Ukuhlolwa kwe-tensile
Izinkomba zokusebenza eziqinile zamapayipi ensimbi angenamthungo kanye namapayipi ensimbi e-ERW womabili ahlangabezana nezindinganiso ze-API, kodwa amandla amapayipi ensimbi engenamthungo ngokuvamile asemkhawulweni ongaphezulu futhi ubupulasitiki busemkhawulweni ophansi. Uma kuqhathaniswa, inkomba yamandla yamapayipi ensimbi e-ERW ingcono kakhulu, futhi inkomba ye-plasticity ingama-33.3% ephakeme kunezinga elijwayelekile. , isizathu siwukuthi ukusebenza kwamakhoyili agingqiwe ashisayo, izinto ezingavuthiwe zamapayipi ensimbi e-ERW, aqinisekiswa kusetshenziswa ukuncibilika kwe-microalloying, ukucwenga ngaphandle kwesithando somlilo, nokupholisa nokugingqika okulawulwayo; amapayipi ensimbi angenamthungo ikakhulukazi ancike ezindleleni zokwandisa okuqukethwe kwekhabhoni, okwenza kube nzima ukuqinisekisa amandla kanye nepulasitiki. ukufana okunengqondo.

⑥Ukuqina
Impahla eluhlaza yamapayipi ensimbi e-ERW - amakhoyili agoqelwe ashisayo, inokunemba okuphezulu kakhulu ekupholiseni okulawulwayo kanye nokugingqika phakathi nenqubo yokugingqa, okungaqinisekisa ukusebenza okufanayo kwazo zonke izingxenye zamakhoyili.

⑦Usayizi wokusanhlamvu
Impahla eluhlaza yepayipi lensimbi ye-ERW - ikhoyili egqinsiwe egqinsiwe yenziwe nge-billet eqhubekayo ebanzi futhi ewugqinsi, enongqimba oluqinile lokusanhlamvu okusanhlamvu, ayikho indawo yekristalu eyikholomu, umgodi wokushwabana nokuxega, ukuchezuka kokwakheka okuncane, nokuminyene. isakhiwo; enqubweni elandelayo yokugoqa Phakathi kwazo, ukusetshenziswa kokupholisa okulawulwayo kanye nobuchwepheshe bokugoqa obulawulwayo buqinisekisa futhi usayizi wokusanhlamvu wezinto zokusetshenziswa.

⑧Goqa ukuhlolwa kokumelana
Ipayipi lensimbi le-ERW libonakala ngezinto zalo ezingavuthiwe kanye nenqubo yokwenza amapayipi. Ukufana kokuqina kodonga lwayo kanye nokuma kweqanda kungcono kakhulu kunamapayipi ensimbi angenamthungo, okuyisizathu esiyinhloko sokuthi kungani ukusebenza kwayo kokungabhidliki kuphakeme kunokwamapayipi ensimbi angenamthungo.

⑨Ukuhlolwa komthelela
Njengoba ukuqina komthelela wesisekelo samapayipi ensimbi e-ERW buphindwe izikhathi eziningana kowamapayipi ensimbi angenamthungo, ukuqina komthelela we-weld kuwukhiye wamapayipi ensimbi e-ERW. Ngokulawula okuqukethwe okungcolile kwezinto ezingavuthiwe, ukuphakama kanye nendlela yokusika ama-burrs, ukuma konqenqema olwakhiwe, i-engeli yokushisela, isivinini sokushisela, amandla okushisa, kanye nemvamisa, inani le-welding extrusion, izinga lokushisa eliphakathi lokuhoxiswa kanye nokujula, umoya. ubude besigaba sokupholisa kanye neminye imingcele yenqubo iqinisekisa ukuthi amandla omthelela we-weld afinyelela ngaphezu kuka-60% wesisekelo sensimbi. Uma ethuthukisiwe ngokwengeziwe, amandla omthelela we-weld angasondela kulawo ensimbi engumzali. izinto zokwakha, okuholela ekusebenzeni okungenamthungo.

⑩Ukuhlolwa kokuqhuma
Ukusebenza kokuhlolwa kokuqhuma kwamapayipi ensimbi e-ERW kuphakeme kakhulu kunezidingo ezijwayelekile, ikakhulukazi ngenxa yokufana okuphezulu kokuqina kodonga kanye nobubanzi obufanayo bangaphandle bamapayipi ensimbi e-ERW.

⑪Ukuqondisa
Amapayipi ensimbi angenasici akhiwa esimweni sepulasitiki, futhi ngombusi owodwa (izikhathi ezi-3 kuya kwezi-4 umbusi wokugoqa okuqhubekayo), ukuqondisa kokuphela kwepayipi kunzima ukulawula;
Amapayipi ensimbi e-ERW acutshungulwa ngokubanda futhi anokuqondisa ku-inthanethi esimweni esincishisiwe sobubanzi. Ngaphezu kwalokho, ziphindaphindeka ngokungenamkhawulo, ngakho ukuqondisa kungcono.

⑫Inani lensimbi elisetshenziselwa ukufakwa kwe-casing ngamamitha ayi-10,000 wevidiyo
Ugqinsi lwamapayipi ensimbi e-ERW alufani futhi ukubekezelela ukushuba kodonga akunakwa, kuyilapho umkhawulo wokunemba wokulawula umehluko wokushunqa odongeni wamapayipi ensimbi angenamthungo ngu-±5%t, ovame ukulawulwa kokuthi ±5~10%t. Ukuqinisekisa ukuthi ubukhulu obuncane bodonga bungahlangabezana nezidingo ezijwayelekile nokusebenza, okuwukuphela kwesixazululo ukukhulisa ubukhulu bodonga ngendlela efanele. Ngakho-ke, ekufakweni kwemininingwane efanayo nesisindo, amapayipi ensimbi e-ERW made ngo-5 kuya ku-10% kunamapayipi ensimbi angenamthungo, noma ngisho nangaphezulu, okunciphisa ukusetshenziswa kwensimbi ye-casing ngamamitha angu-10,000 wevidiyo ngo-5 kuya ku-10%. Ngisho nangenani elifanayo, amapayipi ensimbi e-ERW asindisa abasebenzisi u-5 kuya ku-10% wezindleko zokuthenga.

Kafushane: Nokho, okwamanje amazwe asekhaya nawangaphandle asasebenzisa angenamthungo, ngoba izinga lamanje lensimbi yensimbi yamapayipi ensimbi e-ERW lingalawulwa kuphela ngenani eliphakeme kakhulu le-K55. Uma izinga lensimbi liphakeme, asinawo amandla okukhiqiza asekhaya. Mayelana nemakethe yamanje yamapayipi ensimbi ye-ERW, imishini yokukhiqiza yaseJapane kanye nobuchwepheshe bokukhiqiza kusengafinyelela izinga elithile lokukhiqiza i-casing, kodwa ingakhiqiza kuphela kufika ku-N80. Uma ufuna ukukhiqiza i-P110 noma amamaki aphezulu ensimbi, okwamanje kunomkhawulo othile. Ubunzima, ngakho-ke ipayipi lensimbi le-ERW lingasetshenziswa kuphela njengewashi.
