Umbhobho weSsimbi oSpiral okumgangatho ophezulu
Izinto ezisetyenziswa ngokuqhelekileyo umbhobho ojikelezayo e-China zibandakanya ngokubanzi: Q235A, Q235B, Q345, L245, L290, X42, X52, X60, X70, X80, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Nicr18ni18ni18ni1.Imigangatho eqhelekileyo kwimibhobho ejikelezayo yahlulahlulwe ngokubanzi ibe: SY / t5037-2018 (umgangatho womphathiswa, okwaziwa ngokuba yi-spiral seam entywilayo ye-arc edityanisiweyo yentsimbi yombhobho wokuhambisa ulwelo oluqhelekileyo), GB / T9711.1-1997 (umgangatho wesizwe, owaziwa ngokuba iimeko zokuhanjiswa kwezobugcisa zothumelo lwentsimbi yombhobho kwishishini leoli negesi, icandelo I: iklasi umbhobho wentsimbi (GB / t9711.2 iklasi B umbhobho yentsimbi kunye neemfuno ezingqongqo)), api-5l (American Petroleum Association, eyaziwa ngokuba umbhobho yentsimbi pipeline );Kubandakanya i-PSL1 kunye ne-PSL2), i-SY / t5040-92 (i-spiral submerged arc welded steel pipe yengqumba).
(1) iimathiriyeli ekrwada, okt strip steel coil, ucingo welding kunye flux.Ukuhlolwa okungqongqo ngokomzimba kunye neekhemikhali kuya kwenziwa phambi kokufakwa
(2) Umdibaniso wempundu wentloko yentsimbi kunye nomsila wamkela ucingo olunye okanye ucingo oluphindwe kabini oluntywiliselwe i-arc ukuwelda, kunye nokuwelda okuzenzekelayo okuntywiliselwa kwe-arc kwamkelwe ukuwelda ukulungiswa emva kokuqengqeleka kumbhobho wentsimbi.
(3) Phambi kokwenziwa, intsimbi yomtya iyalungiswa, ilungiswe, icwangciswe, icocwe, ithuthwe kwaye igotywe ngaphambili.
(4) Igeyiji yoxinzelelo lombane isetyenziselwa ukulawula uxinzelelo lwesilinda yeoli ecinezelayo kumacala omabini okuhambisa ukuqinisekisa ukuthuthwa okugudileyo kwentsimbi yomtya.
(5) Ukwamkela ulawulo lwangaphandle okanye ukwenziwa koluhlu lolawulo lwangaphakathi
(6) Isixhobo sokulawula umsantsa we-weld sisetyenziselwa ukuqinisekisa ukuba umsantsa we-weld uyahlangabezana neemfuno ze-welding, kunye nobubanzi bombhobho, ukungahambi kakuhle kunye ne-weld gap zilawulwa ngokungqongqo.

(8) Zonke i-welds ezidibeneyo zihlolwe yi-intanethi eqhubekayo ye-ultrasonic i-flaw detector yokuqinisekisa i-100% ye-NDT yokugubungela i-spiral welds.Ukuba kukho iziphene, iya ngokuzenzekelayo i-alamu kunye namanqaku okutshiza, kwaye abasebenzi bemveliso baya kulungelelanisa iiparamitha zenkqubo nangaliphi na ixesha ukuphelisa iziphene ngexesha.
(9) Umbhobho wensimbi unqunywe kwiinqununu enye ngomatshini wokusika iplasma yomoya
(10) Emva kokusikwa kumbhobho wentsimbi enye, ibhetshi nganye yombhobho wentsimbi iya kuxhomekeka kwindlela engqongqo yokuhlola kuqala ukujonga iimpawu zomatshini, ukwakheka kweekhemikhali, imeko yokudibanisa, umgangatho womphezulu wombhobho wentsimbi kunye ne-NDT ukuqinisekisa ukuba ukwenza umbhobho. inkqubo ifanelekile phambi kokuba ifakwe ngokusemthethweni kwimveliso
(11) Amalungu anamanqaku aqhubekayo okufumanisa i-acoustic flaw kwi-weld aya kujongwa kwakhona nge-ultrasonic manual kunye ne-X-reyi.Ukuba kukho iziphene, emva kokulungiswa, ziya kuba phantsi kwe-NDT kwakhona de kube kuqinisekiswe ukuba iziphene ziphelisiwe.
(12) Umbhobho wokuwelda umthungo wentsimbi yomtya kunye ne-T-joint intersecting spiral weld iya kuhlolwa ngumabonakude weX-ray okanye ifilimu.
(13) Ipayipi nganye yensimbi iphantsi kovavanyo lwe-hydrostatic, kwaye uxinzelelo luthatha i-radial seal.Uxinzelelo lovavanyo kunye nexesha lilawulwa ngokungqongqo ngesixhobo sokufumanisa i-microcomputer yoxinzelelo lwamanzi lombhobho wensimbi.Iiparamitha zovavanyo ziprintwa ngokuzenzekelayo kwaye zirekhodwe
(14) Ukuphela kombhobho kumatshini wokulawula ngokuchanekileyo i-perpendicularity, i-angle ye-slope kunye ne-edge e-blunt yobuso besiphelo.Umbhobho odityanisiweyo we-arc we-Spiral odityanisiweyo wokuhambisa ulwelo loxinzelelo usetyenziswa ikakhulu kwimibhobho ethutha i-oyile negesi yendalo.
Umbhobho wensimbi unamandla okuthwala uxinzelelo kunye neplastiki efanelekileyo, ekulungele ukuwelda kunye nokucubungula;I-Spiral seam entywiliselweyo i-arc edityanisiweyo yombhobho wentsimbi yokuhanjiswa kolwelo oluphantsi koxinzelelo oluphantsi lwenziwa ngokudibanisa i-arc enamacala amabini oluzenzekelayo okanye indlela yokuwelda kwicala elinye, esetyenziselwa ukuhanjiswa koxinzelelo oluphantsi jikelele olunjengamanzi, igesi, umoya kunye nomphunga. .
Umbhobho odityanisiweyo othe ngqo uneenzuzo zenkqubo yokuvelisa elula, ukusebenza kakuhle kwemveliso, ixabiso eliphantsi kunye nophuhliso olukhawulezayo.Amandla ombhobho odityanisiweyo we-spiral uphezulu ngokubanzi kunombhobho odityanisiweyo othe ngqo.Inokuvelisa umbhobho odityanisiweyo onedayamitha yombhobho omkhulu ongenanto emxinwa, kunye nombhobho odityanisiweyo onedayamitha yombhobho ongenanto yobubanzi obufanayo.Nangona kunjalo, xa kuthelekiswa nombhobho womthungo othe tye kunye nobude obufanayo, ubude be-weld bunyuka nge-30 ~ 100%, kwaye isantya sokuvelisa siphantsi.Ke ngoko, ukuwelda komthungo okuthe tye kusetyenziswa kakhulu kwimibhobho edityanisiweyo enedayamitha encinci, kwaye i-spiral welding isetyenziswa kakhulu kwimibhobho edityanisiweyo enobubanzi obukhulu.Umbhobho ojikelezayo usetyenziswa ikakhulu kubunjineli bamanzi ompompo, ishishini lepetrochemical, ishishini lemichiza, ishishini lamandla ombane, ukunkcenkceshela kwezolimo kunye nokwakhiwa kwedolophu.Yenye yeemveliso ezingundoqo ezingama-20 eziphuhliswe eTshayina.Ukuthutha ulwelo: unikezelo lwamanzi, ukuhanjiswa kwamanzi, ubunjineli bokucocwa kogutyulo, ukuthuthwa ngodaka, ukuthuthwa kwamanzi olwandle.Ukuhanjiswa kwerhasi: irhasi, umphunga kunye nerhasi yepetroleum engamanzi.Kwisakhiwo: njengombhobho wokuqhuba imfumba kunye nebhulorho;Imibhobho ye-wharf, indlela kunye nezakhiwo zokwakha, imibhobho yokufaka i-marine, njl.
