Q345 Spiral Welded Umbhobho
I-Spiral seam entywiliselwe i-arc welded steel pipe (SY5036-83) yokuthutha ulwelo olunoxinzelelo isetyenziswa ikakhulu kwimibhobho yokuthutha ioyile negesi yendalo;spiral umthungo high-frequency welded umbhobho wentsimbi (SY5038-83) yokuthutha ulwelo olunoxinzelelo, kusetyenziswa indlela ye-welding ye-high-frequency lap Welded, spiral seam high-frequency welded welding pipe yokuthutha ulwelo olunoxinzelelo.Umbhobho wensimbi unamandla okunyamezela uxinzelelo kunye neplastiki enhle, efanelekileyo kwi-welding kunye nokusebenza.Ngokubanzi, i-spiral seam entywiliselweyo i-arc welded steel pipe (SY5037-83) yothutho oluphantsi loxinzelelo lwe-arc lwenziwa ngokudibanisa kwe-arc kumacala amabini oluzenzekelayo okanye ukuwelda kwicala elinye emanzini, umbhobho wentsimbi odityanisiweyo we-arc wokuhambisa ulwelo oluphantsi ngokubanzi. ezifana negesi, umoya kunye nomphunga
(1) Imathiriyeli ekrwada zizikhoyili zentsimbi, iingcingo zokuwelda, kunye ne-fluxes.Ukuhlolwa okungqongqo ngokomzimba kunye neekhemikhali kuyafuneka phambi kotyalo-mali.
(2) Impundu edityanisiweyo yentloko yentsimbi kunye nomsila, yamkele intambo enye okanye ucingo oluphindwe kabini oluntywiliselwe i-arc ukuwelda, emva kokubhijela kumbhobho wentsimbi, yamkele ukuwelda okuzenzekelayo kwe-arc ukulungisa ukuwelda.
(3) Ngaphambi kokuqulunqwa, umgca uhambelana nomgangatho, ukunqunyulwa komphetho, ukucwangciswa komphetho, ukucocwa komphezulu kunye nokuhanjiswa, kunye nokunyangwa kwangaphambili.
(4) I-gauge yokudibanisa yombane isetyenziselwa ukulawula uxinzelelo lweesilinda kumacala omabini omqhubi ukuqinisekisa ukuhanjiswa okugudileyo komcu.
(5) Ukwamkela ulawulo lwangaphandle okanye ukwenziwa koluhlu lolawulo lwangaphakathi.
(6) Isixhobo sokulawula i-welding seam gap sisetyenziselwa ukuqinisekisa ukuba i-gap ye-welding seam iyahlangabezana neemfuno ze-welding, kunye ne-diameter yombhobho, ubungakanani bokungahambi kakuhle kunye ne-welding seam gap zonke zilawulwa ngokungqongqo.
(7) Zombini i-welding yangaphakathi kunye ne-welding yangaphandle zamkela umatshini wokuwelda wombane we-American Lincoln we-welding ye-arc enye okanye i-double-wire submerged arc welding, ukuze ufumane iinkcukacha ezizinzileyo ze-welding.
(8) I-welded seams zonke zihlolwe nge-intanethi eqhubekayo ye-ultrasonic i-flaw isixhobo esizenzekelayo, esiqinisekisa i-100% yovavanyo olungonakalisi ukugubungela i-spiral welds.Ukuba kukho isiphene, kuya ngokuzenzekelayo i-alamu kwaye itshize uphawu, kwaye abasebenzi bemveliso banokuhlengahlengisa iiparitha zenkqubo nangaliphi na ixesha ngokutsho oku ukuphelisa isiphene ngexesha.
(9) Umatshini wokusika i-plasma yomoya usetyenziselwa ukusika umbhobho wensimbi kwiinqununu zomntu ngamnye.
10 ukuqinisekisa ukuba inkqubo yokwenza umbhobho ifanelekile.Emva koko, inokufakwa ngokusemthethweni kwimveliso.
(11) Amalungu aneempawu eziqhubekayo zokufumanisa i-sonic flaw kwi-weld ziphinda zihlolwe yi-manual ultrasonic kunye ne-X-ray.Ukuba kukho isiphene, emva kokulungiswa, kuya kuphinda kuhlolwe ngokungenakonakala kuze kube kuqinisekiswa ukuba i-defect isusiwe.
(12) Imibhobho apho umthungo wentsimbi uthungelwa ngeempundu kunye namalungu amile okwe-D anqumla imithungo ye-welding ejiyileyo yonke ihlolwa ngomabonakude weX-reyi okanye ukufotwa.
(13) Ipayipi nganye yensimbi ifumana uvavanyo loxinzelelo lwe-hydrostatic, kwaye uxinzelelo luthatha uphawu lwe-radial.Uxinzelelo lovavanyo kunye nexesha lilawulwa ngokungqongqo ngumbhobho wensimbi we-hydraulic microcomputer isixhobo sokubona.Iiparamitha zovavanyo ziprintwa ngokuzenzekelayo kwaye zirekhodwe.
(14) Isiphelo sombhobho sicutshungulwa ngoomatshini, ukwenzela ukuba ukuqina kobuso besiphelo, i-angle ye-bevel kunye ne-obtuse edge inokulawulwa ngokuchanekileyo.
Okwangoku, imigangatho esetyenziswa ngokuqhelekileyo kwimibhobho yentsimbi ejikelezayo yahlulwe ngokubanzi ibe: SY/T5037-2000 (umgangatho woMphathiswa, okwabizwa ngokuba yi-spiral seam entywiliselweyo i-arc welding wentsimbi umbhobho wemibhobho yokuthutha ulwelo oluqhelekileyo), GB/T9711.1-1997 (yeSizwe umgangatho, obizwa ngokuba yi-oyile kunye negesi yokuthutha i-industrial industry Inxalenye yokuqala yeemeko zokunikezelwa kwezobugcisa zemibhobho yensimbi: Iipayipi zensimbi zeBanga A (iimfuno ezinzima kakhulu ziyi-GB / T9711.2 yeBanga B iipayipi zensimbi), i-API-5L (i-American Petroleum Institute, Ikwabizwa ngokuba yimibhobho yentsimbi yombhobho; yahlulwe yaba ziindidi ezimbini: i-PSL1 kunye neBanga le-PSL2), i-SY/T5040-92 (i-Spiral submerged arc welded steel pipe for imfumba)
Imathiriyeli ye-Spiral tube:Q235A, Q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb.Q345 L245 L290 X42 X46 X70 X80
Imibhobho yentsimbi ye-Spiral isetyenziswa ikakhulu kubunjineli bonikezelo lwamanzi, ishishini lepetrochemical, ishishini lemichiza, ishishini lamandla ombane, ukunkcenkceshela kwezolimo, kunye nokwakhiwa kwedolophu.Yenye yeemveliso ezingundoqo ezingama-20 eziphuhliswe kwilizwe lam.
Isetyenziselwa ukuthutha ulwelo: ukunikezelwa kwamanzi, ukukhutshwa kwamanzi.Isetyenziselwa ukuthutha igesi: igesi yamalahle, i-steam, i-liquefied petroleum gas.Ngeenjongo zesakhiwo: njengemibhobho yokufumba, njengeebhulorho;iipiers, iindlela, izakhiwo zezakhiwo, njl.
