I-ERW iyipayipi elihlanganisiwe elinokumelana okukhulu nokushibilika; i-LSAW iyipayipi elihlanganisiwe elihlanganisiwe elinokumelana nokushibilika eliqondile elingaphansi komhlaba; womabili angamalungu amapayipi ahlanganisiwe aqondile, kodwa inqubo yokushibilika kanye nokusetshenziswa kwawo womabili kuhlukile, ngakho awakwazi ukumela amapayipi ahlanganisiwe aqondile kuphela. Amapayipi ahlanganisiwe e-SSAW-spiral welding-spiral avame kakhulu.

Umehluko kanye nokusetshenziswa kwamapayipi ensimbi e-ERW, LSAW kanye ne-SSAW

Imvamisa ephezulu yomthungo oqondile (ipayipi lensimbi le-ERW) ihlukaniswe ngokushisela kokungeniswa kanye nokushisela kokuxhumana ngokwezindlela ezahlukene zokushisela. Isebenzisa amakhoyili abanzi ashibilika ngokushisa njengezinto zokusetshenziswa. Ngemva kokugoba ngaphambi, ukwakheka okuqhubekayo, ukushisela, ukwelashwa kokushisa, ukunamathisela, ukuqondisa, ukusika, inezinzuzo zokushisela okufushane, ukunemba okuphezulu, ukujiya kodonga okufanayo, ikhwalithi enhle yobuso kanye nokucindezela okuphezulu uma kuqhathaniswa nokugoba. Kodwa-ke, ububi ukuthi amapayipi abhityile kuphela anobubanzi obuncane nobuphakathi angakhiqizwa. Ukuhlanganiswa, amaphutha okugqwala afana nomsele. Izindawo ezisetshenziswa kabanzi njengamanje ukuthuthwa kwemikhiqizo yegesi yemvelo yasemadolobheni kanye nowoyela ongahluziwe.

Ukushisela i-arc engaphansi komphetho oqondile (ipayipi lensimbi le-LSAW) kukhiqizwa ngokusebenzisa ipuleti elilodwa eliphakathi nendawo nelibanzi njengezinto zokusetshenziswa, ukucindezela (ukugoqa) ipuleti lensimbi emshinini wokubumba noma wokwakha, ukushisela i-arc engaphansi komphetho enamacala amabili, nokwandisa ububanzi. Umkhiqizo oqediwe unezinhlobo eziningi zezincazelo, ukuqina okuhle kokushisela, i-plasticity, ukufana kanye nobuningi, futhi unezinzuzo zobubanzi obukhulu bepayipi, udonga olukhulu lwepayipi, ukumelana nokucindezela okuphezulu, ukumelana nokushisa okuphezulu kanye nokumelana nokugqwala. Lapho wakha amapayipi kawoyela negesi aqinile kakhulu, aqinile kakhulu, asezingeni eliphezulu, amapayipi ensimbi adingekayo ikakhulukazi amapayipi angaphansi komphetho oqondile anobubanzi obukhulu. Ngokwezinga le-API, kumapayipi amakhulu kawoyela negesi, lapho edlula ezindaweni zeKlasi 1 kanye neKlasi 2 (njengezindawo zezintaba, olwandle, kanye nezindawo zasemadolobheni ezinabantu abaningi), i-arc engaphansi komphetho oqondile iyona kuphela uhlobo olukhethiwe lwepayipi. Ngokwezindlela ezahlukene zokwakha, ingahlukaniswa ibe: U0E/JCOE/HME.

Ukushisela i-arc engaphansi komhlaba (ipayipi lensimbi le-SSAW) kusho ukuthi uma ugingqa ipayipi, isiqondiso salo sangaphambili sise-engeli (elungisekayo) emgqeni ophakathi wepayipi yokwakha, futhi ukushisela kwenziwa ngesikhathi sokwakha, futhi ukushisela kwalo kwakha umugqa ojikelezayo. Inzuzo ukuthi incazelo efanayo ingakhiqiza amapayipi ensimbi anobubanzi obuhlukahlukene, izinto zokusetshenziswa zinokuvumelana nezimo okubanzi, ukushisela kungagwema ukucindezeleka okuyinhloko, futhi ukucindezeleka kuhle. Okubi ukuthi usayizi wejometri awulungile. Ubude be-weld bude kunobomthungo oqondile. Imifantu, ama-pores, ukufakwa kwe-slag kanye nokuphambuka kokushisela kuyenzeka. Uma kwenzeka amaphutha okushisela, ukucindezeleka kokushisela kusesimweni sokucindezeleka okuqinile.

Imininingwane yomklamo wamapayipi ajwayelekile kawoyela negesi aqhelelene ibanga elide ibeka ukuthi i-spiral submerged arc ingasetshenziswa kuphela ezindaweni ze-Class 3 kanye ne-Class 4. Ngemva kokuthuthukisa inqubo kwamanye amazwe, izinto zokusetshenziswa zithathelwa indawo ngamapuleti ensimbi ukuze kuhlukaniswe ukwakheka kanye nokushisela. Ngemva kokushisela ngaphambi kokufakelwa kanye nokunemba, ububanzi bokushisela buzokhula ngemva kokushisela okubandayo. Ikhwalithi yokushisela iseduze nepayipi le-UOE.
Okwamanje, ayikho inqubo enjalo eShayina. Lesi yisiqondiso sokuthuthukiswa kwefektri yethu. Ipayipi "lokuThunyelwa kwegesi eNtshonalanga-mpumalanga" lisakhiqizwa ngokwenqubo yendabuko, kodwa ububanzi bokuphela kwepayipi selwandisiwe.
I-United States, iJapani kanye neJalimane ngokuvamile ziyenqaba ukusebenzisa i-SSAW futhi zikholelwa ukuthi umugqa oyinhloko akufanele usebenzise i-SSAW.
ICanada ne-Italy zisebenzisa i-SSAW kancane, kanti iRussia isebenzisa i-SSAW ngobuningi obuncane. Bakhe izimo ezengeziwe eziqinile kakhulu. Ngenxa yezizathu zomlando, imigqa eminingi ye-trunk yasekhaya isasebenzisa i-SSAW. Izinto zokusetshenziswa zishintshwa zibe yipuleti lensimbi ukuze zihlukaniswe ukwakheka kanye nokushintshwa. Ngemva kokushintshwa kwangaphambi kokushintshwa kanye nokunemba, ububanzi bokushintshwa buzokwandiswa ngemva kokushintshwa okubandayo. Ikhwalithi yokushintshwa iseduze nepayipi le-UOE.
Ipayipi elihlanganisiwe le-ERW eliqondile livame ukusetshenziswa njenge-casing yentambo embonini yamandla. Izici zokusebenza: Ukuhlolwa kwe-ultrasonic okungu-100% kwezinto zomzali kuqinisekisa ikhwalithi yangaphakathi yomzimba wepayipi; ayikho inqubo yokusika idiski evulekile, futhi izinto zomzali zinezimbobo ezincane kanye nemihuzuko; ipayipi eliqediwe ngemuva kokususwa kokucindezeleka empeleni alinawo ukucindezeleka okusele; ukushintshwa kufushane futhi amathuba okuba neziphambeko mancane; lingathutha igesi yemvelo emanzi emuncu; ngemva kokwandiswa kobubanzi, ukunemba kobukhulu bejometri yepayipi lensimbi kuphezulu; ukushintshwa kwenziwa emgqeni oqondile endaweni evundlile ngemva kokwakhiwa kuqediwe, ngakho-ke ukungalungi kahle, ukuvulwa komthungo, kanye nobubanzi bepayipi kulawulwa kahle, futhi ikhwalithi yokushintshwa ihle kakhulu. Izindinganiso ezisebenzayo zomkhiqizo: I-API 5L, i-API 5CT, i-ASTM, i-EN10219-2, i-GB/T9711, 14291-2006 nezinye izindinganiso zakamuva. Amazinga ensimbi yomkhiqizo afaka: i-GRB, i-X42, i-X52, i-X60, i-X65, i-X70, i-J55, i-K55, i-N80, i-L80, i-P110, njll. Imikhiqizo isetshenziswa kabanzi ku-oyili, igesi yemvelo, igesi yamalahle, izimayini zamalahle, imishini, ugesi, ukufaka inqwaba kanye nezinye izinjongo. Imishini yobuchwepheshe benqubo ethuthukisiwe: njengokubumba kwe-W-FF, ukushisela okuqinile kwe-induction okujwayelekile, ukutholwa kwamaphutha e-ultrasonic, ukutholwa kwamaphutha okuvuza kwe-magnetic flux, kanye nezinsimbi zokuhlola eziphezulu: njengokuhlaziywa kwe-metallographic, umhloli wokuqina kwe-Vickers, umshini wokuhlola umthelela, i-spectrum analyzer, umshini wokuhlola we-universal kanye neminye imishini. Imikhiqizo ithunyelwa eNingizimu Melika, eNyakatho Melika, e-European Union, eNingizimu-mpumalanga ye-Asia nakwezinye izindawo. Eminyakeni edlule, yamukelwe kahle ngamakhasimende emhlabeni wonke.

Inkampani yethu ihlinzekaEN10210I-S235JRH, S275JOH, S275J2H, S355JOH,S355J2H, S355K2H, enezincazelo ezisukela kububanzi bangaphandle obungu-219-1216, ubukhulu bodonga obungu-6-40, kanye newaranti yokuqala yasefektri. Amakhasimende emhlabeni wonke amukelekile ukuthenga.
