Eyodwa. Ukwethulwa kwenqubo yokukhiqiza yeububanzi obukhulungibone ipayipi lensimbi
Umshini wokuzulazula → I-Uncoiler → I-Unwinder → Umshini wokulinganisa we-Retripper → Ukumisa phakathi kweroli eqondile → Ukushisela izinqe ze-Shear→ Ukulawula ukuma kwe-Strip (i-rola eqondile enekhanda elikabili) → Ukugunda idiski→ Ukulawula ukuma kwe-Strip (Irola eqondile enekhanda elikabili )→ Umshini Wokugaya Umphetho (I-Fine Milling I-X Groove)→ I-Double End Roller→ Ukuhlanzwa Kwemicu Yemicu→ I-Double End Roller→ I-Conveyer→ I-Strip Feeding kanye Nokulawula Isimo Se-Strip→ Umshini Wokubumba→I-Inner Welding→I-Welding Outside → idivayisi yokuqondisa ipayipi yensimbi → ukusika i-plasma → ipayipi lensimbi lomthungo oqondile

Okubili. Imininingwane yenqubo yokukhiqiza yobubanzi obukhulu bepayipi lensimbi ye-lsaw
1. Sebenza ngaphambi kokwenza
Izinto ezingasetshenzisiwe amakhoyili ensimbi, izintambo zokushisela, kanye ne-flux. Kufanele udlule ekuhlolweni okuqinile ngokomzimba namakhemikhali ngaphambi kokutshala imali. Amalunga ezinqenqema zensimbi ashiselwe nge-monofilament noma i-arc welding enezintambo ezimbili ezingaphansi kwamanzi. Ngemuva kokuthi ishubhu yensimbi igoqwe, ukushisela kwe-arc okuzenzakalelayo kusetshenziselwa ukushisela.

2. Inqubo yokubumba
I-gauge yokucindezela kokuxhumana kagesi isetshenziselwa ukulawula ingcindezi yamasilinda okucindezela ezinhlangothini zombili zomthumeli ukuze kuqinisekiswe ukulethwa okushelelayo komugqa. Umshini omkhulu ubekwe phakathi nendawo. Ngakho-ke, ukulungiswa kwe-roller eqondile (ikakhulukazi ngaphambi nangemva kwekhanda) kufanele kuhlolwe njalo ukuze kuqinisekiswe umkhawulo oqinile wokulethwa komugqa. Gijimani emzileni oshiwo yinqubo bese udlula iphoyinti eliklanyelwe le-meshing. Ukulawulwa kwangaphandle noma ukwakhiwa komqulu wokulawula kwangaphakathi kusetshenziselwa ukuhlola ukuthi i-perimeter, i-ellipticity, ukuqondisa, njll. kwepayipi lensimbi kuyahambisana nezidingo ezijwayelekile. Uma ingahlangabezani nezidingo, izoqhubeka nokulungiswa ize ihlangabezane nezidingo.

3. Inqubo yokushisela
Idivayisi yokulawula igebe lokushisela isetshenziselwa ukuqinisekisa ukuthi igebe lokushisela liyanelisa izidingo zokushisela. Ububanzi bepayipi, inani lokungaqondani kahle, kanye negebe lokushisela konke kulawulwa ngokuqinile. Ikhwalithi ye-seam yokwenza kufanele ibhekwe ngokuqhubekayo, futhi kufanele kutholakale ukuthi imiphetho engalungile, ama-seams avulekile, njll. Hlela kahle i-angle ye-axle yangemuva ngesikhathi ukuze uqinisekise ikhwalithi yokubunjwa; lapho isimo singavamile, hlola ukuthi ububanzi bokusebenza be-strip, isimo sangaphambi kokugoba konqenqema, indawo yomugqa wokulethwa, i-angle ye-roller encane, njll. ishintshile, futhi uthathe izinyathelo zokulungisa ngesikhathi. Abakhiqizi bamapayipi ensimbi yomthungo oqondile we-Hebei njengamanje basebenzisa umshini wokushisela wase-United States Lincoln wocingo olulodwa noma i-arc welding enezintambo ezimbili ezingaphansi kwamanzi ukuze bathole ikhwalithi yokushisela ezinzile. Abakhiqizi bamapayipi ensimbi yomthungo oqondile kufanele baqhubeke bebheka ikhwalithi yamalunga akha amalunga, futhi bazolungisa ngokushesha i-engeli ye-axle yangemuva ukuze baqinisekise ikhwalithi yokubumba esimweni sokungahambi kahle kwemiphetho, imithungo evulekile, njll.; uma izimo zingajwayelekile, hlola ububanzi bokusebenza, unqenqema lwesimo sokugoba, kanye nokulethwa komugqa wensimbi. Ukuthi ngabe kukhona noma yiluphi ushintsho endaweni yomugqa, i-engeli encane yerola, njll., futhi uthathe izinyathelo zokulungisa ngesikhathi.

4. Ukutholwa
Ama-weld ashiselwe wonke ahlolwe ku-inthanethi ngomtshina ozenzakalelayo we-ultrasonic flaw ukuze kuqinisekiswe ukumbozwa kokuhlolwa okungabhubhisi okungu-100% kwe-spiral weld. Uma kuneziphambeko, zizokwethuka ngokuzenzakalelayo futhi zipendwe. Abasebenzi abakhiqizayo bazolungisa amapharamitha enqubo nganoma yisiphi isikhathi ukuze baqede amaphutha ngesikhathi. Lapho ububanzi obuningi D ≥ 426mm, ukukhubazeka kwangaphakathi kwepayipi lensimbi kufanele kuhlanzwe futhi kulungiswe ngaphakathi; lapho D ≤ 426mm, amaphutha angaphakathi angasuswa ngaphandle ukuze enze i-welding yangaphandle. Ngemuva kokulungisa i-welding, i-weld kufanele ibe phansi futhi ukushuba kodonga olusele ngemuva kokugaya kufanele kube ngaphakathi kokubekezelelana kodonga olucacisiwe. Ngaphambi kokulungisa ipayipi yensimbi ehlanganisiwe kwinqubo elandelayo, kuyadingeka ukuhlola ngokucophelela ukuthi kukhona yini ukukhubazeka okulahlekile noma okuphuthelwe kwipayipi yensimbi futhi uyilungise ngaphambi kokuqhubeka nenqubo elandelayo. Amalunga anezinqe ezishiselwe amajoyinti anezinqe zensimbi namashisela avunguzayo konke kwahlolwa ngethelevishini ye-X-ray noma ifilimu. Ipayipi ngalinye lahlolwa nge-hydrostatic futhi umfutho wawuvalwe nge-radial. Ingcindezi yokuhlola nesikhathi kulawulwa ngokuqinile ipayipi lensimbi le-hydraulic pressure testing device. Imingcele yokuhlola iphrintwa futhi irekhodwe ngokuzenzakalelayo.

5. Ukupakisha ngaphandle komtapo wolwazi
Ipayipi ekugcineni machining, ukuze ekugcineni ubuso perpendicularity, i-groove angle kanye blunt onqenqemeni kulawulwa ngokunembile. Umsiki weplasma yomoya usika ishubhu lensimbi libe izingcezu ngazinye. Ngemuva kokuthi i-blade ibuthuntu noma ilimele, i-blade entsha kufanele ishintshwe ngokushesha. Insimbi entsha kufanele ilolwe ngetshe ngaphambi kokuba isetshenziswe, futhi akufanele igaywe ngomshini wokugaya. Ngemva kokuba i-blade iphukile, ingasetshenziswa ngemva kokufaka itshe lokugaya futhi ngemva kokugaya nge-grinder.
