Liyini ishubhu yesikwele esinamandla amakhulu?

Izici zokusebenza zehigh-amandla square tubeamandla aphezulu, ukuqina okuhle kanye nokumelana nomthelela.
Amandla: iphuzu lesivuno (σ s)≥390mpa;
Amandla okuqina (б b)≥635mpa;
Ubude δ 5 (%)≥25;
Ukuqina hb ≤ 187hv,
Ukucaciswa kokwelashwa kokushisa: normalizing 850 ° C; Ukushisa ku-880 ° C; Ukushisa ku-600 ° C.
Material: yenziwe ngekhwalithi ephezuluinsimbi yesakhiwo se-carbonngokuginqika okushisayo noma umdwebo obandayo.
Ukusetshenziswa: okusetshenziselwa ukukhiqiza ipayipi lodonga elipholile ngamanzi, ipayipi lamanzi abilayo, ipayipi le-locomotive water tank steam kanye ne-arch brick pipe, njll.
Ukucaciswa kanye nekhwalithi yokubukeka:
Iqoqo ngalinye leamapayipi ensimbiiyohlolwa ngayinye ngayinye, futhi ingaphezulu ngeke libe nemifantu, imiphetho kanye nokukhubazeka kwesikhumba; Ukutholwa kwamaphutha e-Ultrasonic kuzokwenziwa epayipini ngalinye lensimbi ukuze kuhlolwe izici zemishini ze-weld. Ngokuvamile, ububanzi bokuqinisa ubude be-weld bungu-0.2-0.25mm, ububanzi bokuqinisa ubude be-weld ejikelezayo bungu-0.75-1mm, futhi ukuqina kokucindezeleka kwe-longitudinal esokhethi akufanele kube ngaphansi kuka-0.25mm
Ukwakheka kwamakhemikhali Ukwakheka kwamakhemikhali omkhiqizo oqediwe kuvumelana nezinhlinzeko ze-GB 222-84.
Izakhiwo zomzimba nezemishini:
1) Ijika le-stress-strain lokuhlolwa kwe-tensile lizoba flat ngaphandle koshintsho olusheshayo
2) Ukuhlolwa komthelela Ukuqina komthelela wezinga lokushisa eliphansi kwesampula kuhlolwa indlela yokuhlola yokugoba okubandayo kumazinga okushisa ashiwo.
3) Imifantu ayivunyelwe kumapayipi avuthiswe ngama-hydraulic noma ama-pneumatic devices
I-4) Ukungafani kokucindezeleka kokuhlolwa kokugoba ngeke kudlule inani elishiwo.
Ukugeleza kwenqubo: Ngemuva kokuthi umugqa wensimbi ufakwe ngokuzenzakalelayo ku-disc shape encane futhi ukhiqizwa ngokuqhubekayo, ulinganiswe nge-multi-pass straightener, bese ungena kuyunithi ye-welding ye-high-frequency. Iziphetho ezimbili ziboshwe yi-high-frequency lap welder ukuze zakhe i-circular corrugated welding. Ngemuva kokushisela, ipayipi lensimbi lilinganiswa futhi linqunywe yiyunithi yokulinganisa nokusika. Ekugcineni, ipayipi lensimbi liyacinywa futhi lifakwe iyunithi yokuqedela, bese lifafazwa nge-primer ukuze kuqedelwe inqubo yokukhiqiza.
