UMvelisi weMibhobho yentsimbi eKhokelayo kunye noMboneleli eTshayina |

Yintoni i-SAWL kwiiNdlela zeMibhobho kunye ne-SAWL yokuVelisa?

Umbhobho wentsimbi ye-SAWLngumbhobho wentsimbi odityaniswe ngobude owenziwe kusetyenziswa inkqubo ye-Submerged Arc Welding (SAW).

SAWL= LSAW
Izikhundla ezimbini ezahlukeneyo zobuchule bokuwelda zombini zibhekisa kwimibhobho yentsimbi edityanisiweyo ene-arc-welding.Olu luhlu lwamagama lusisiphumo semigaqo yolwimi kunye nomahluko wengingqi, kodwa ngokusisiseko, zombini zichaza inkqubo efanayo yokwenziwa.

Iindlela zokwenziwa kwe-SAWL

Ukukhetha ipleyiti kunye noLungiselelo → Ukusika kunye noMphetho wokugaya → Ukwenza → Ukuthunga kunye nokuwelda kwangaphambili → Ukuwelda kwe-Seam yangaphakathi nangaphandle → Ukuhlolwa kwe-Welding ye-Welding → Ukuqondisa, Ukwandiswa okubandayo kunye nokusikwa kubude → Unyango loBushushu → Unyango loMphezulu kunye noKhuseleko → Ukuhlolwa kokuGqibela kunye nokuPakisha

Ukukhethwa kwepleyiti kunye nokuLungisa

Ukukhethwa kwezinto ezifanelekileyo zentsimbi yentsimbi, ngokuqhelekileyo i-carbon steel high-high-high okanye i-alloy steel plate.

Ipleyiti yentsimbi kufuneka iphathwe umphezulu ukususa umhlwa, ioli, kunye nobunye ukungcola phambi kokwenziwa.

SAWL inkqubo edge yokusila

Ukusika kunye noMphetho wokugaya

Ukusika iipleyiti zetsimbi: Ukusika iipleyiti zetsimbi ukuya kubukhulu obufanelekileyo ngokobubanzi bombhobho wensimbi oza kuveliswa.

Edge milling: usebenzisa umatshini wokungqusha edge, ukususa burrs kunye nemilo edge efanelekileyo.

Ukwenziwa kwenkqubo ye-SAWL

Ukubumba

Ipleyiti yentsimbi ethe tyaba igotywa kwilitye lokusila ukuze ibunjwe ngokuthe ngcembe ibe yimilo evulekileyo ye-cylindrical.Inkqubo yokwenziwa ngokubanzi yi-JCOE.

SAWL inkqubo seams

Ukuthunga kunye ne-pre-welding

Ukusebenzisa i-seamer yangaphambili, i-seam, kunye ne-welding yangaphambili yenziwa.

I-welding yangaphambili ekupheleni kweeplate ukulungisa imilo kunye nokuqinisekisa ukudibanisa okuchanekileyo kwe-butt yeetyhubhu ngexesha lenkqubo ye-welding engundoqo.

Ukuwelda komthungo wangaphakathi nangaphandle

Inkqubo ye-SAWL ye-welding yangaphandle

Amacala amade (i-longitudinal seams) yombhobho idityanisiwe kusetyenziswa ubuchule be-arc welding.Eli nyathelo lidla ngokuqhutywa ngaxeshanye ngaphakathi nangaphandle kombhobho.

I-arc welding ephantsi kwamanzi iqhutyelwa kwindawo evaliweyo okanye i-semi-enclosed apho indawo ye-weld ihlanganiswe nenani elikhulu lokunyuka ukukhusela i-oxidation kunye nokugcina i-weld icocekile.

Ukuhlolwa kwe-Welding Seam

Emva kokugqiba i-weld, i-weld ihlolwe ngokubonakalayo kwaye ayibonakalisi (umzekelo, i-X-ray okanye uvavanyo lwe-ultrasonic) ukuqinisekisa ukuba i-weld ayinaziphene kwaye ihlangabezana nemigangatho yomgangatho.

Ukulungelelanisa, Ukwandiswa okubandayo kunye nokuSika kuBude

Ukusebenzisa umatshini wokulungisa, lungisa umbhobho wensimbi.Qinisekisa ukuba ukuchaneka kombhobho wensimbi kuhlangabezana neemfuno eziqhelekileyo

Yandisa umbhobho wensimbi ngokusebenzisa umatshini wokwandisa ububanzi ukuze ufezekise ububanzi obuchanekileyo kunye nokuphelisa uxinzelelo loxinzelelo.

Sika umbhobho wensimbi ubude obuchaziweyo ngokweemfuno zabathengi.

Unyango lobushushu

Ukuba kuyimfuneko, iityhubhu ziphathwa ubushushu, ezifana nesiqhelo okanye i-annealed, ukunyenyisa iipropathi zomatshini zemibhobho kunye nokomeleza ukuqina nokomelela.

Unyango kunye noKhuseleko loMphezulu

Ukunyangwa kwe-coating, njenge-anti-corrosion coatings, ifakwe kumphezulu wemibhobho yensimbi ukuphucula ukuxhathisa ukubola kunye nobomi benkonzo.

Ukuhlolwa kokuGqibela kunye nokuPakisha

Ekugqityweni kwawo onke amanyathelo okwenziwa, ukuhlolwa komgangatho wokugqibela kwenziwa ukuqinisekisa ukuba imveliso ihlangabezana neenkcukacha.Ukupakishwa okufanelekileyo kwenziwa ukulungiselela ukuthunyelwa.

I-SAWL yentsimbi yesiXhobo seMveliso yeNsimbi

Umatshini wokusika ipleyiti yentsimbi, umatshini wokugaya ipleyiti yentsimbi, umatshini wokugoba ipleyiti yangaphambili, umatshini wokwenza umbhobho wentsimbi, umbhobho wentsimbi wangaphambili umatshini wokuwelda umthungo, umatshini wokuwelda wangaphakathi, umatshini wokuwelda wangaphandle, umatshini wentsimbi wokujikeleza, ukugqiba umatshini wokulungisa, i-flat head chamfering. umatshini, umatshini wokwandisa.

Izinto eziphambili ze-SAWL

Intsimbi yeCarbon

Eyona nto ixhaphakileyo kwizicelo ezininzi ezisemgangathweni.Intsimbi yekhabhoni iyahluka ngokomxholo wayo wekhabhoni kunye nezinye izinto ezidityanisiweyo ezongeziweyo ukulungelelanisa amandla ayo, ukuqina, kunye nokumelana nomhlwa.

Intsimbi ye-alloy ephantsi

Ubungakanani obuncinci bezinto ezidibeneyo (umzekelo, i-nickel, i-chromium, i-molybdenum) yongezwa ukuphucula iipropati ezithile, ezifana nokushisa okuphantsi okanye ukuxhatshazwa kokugqoka.

Amandla aphezulu aPhantsi iAlloy Steels (HSLA):

Iingoma eziyilwe ngokukodwa ezisezantsi zealloyi zibonelela ukomelela okongeziweyo kunye nokuqina ngelixa kugcinwa ukuwelda okulungileyo kunye nokubumba.

Yenziwe ngentsimbi eshayinayo

Isetyenziswa kwindawo ezonakalisa kakhulu ezifana nezixhobo zokuphatha iikhemikhali ezingaphantsi kolwandle okanye.Ityhubhu yentsimbi engenastainless ibonelela ngokugqwesa okugqwesileyo kunye nokumelana nobushushu obuphezulu.

Imilinganiselo ye-SAWL yeNkcazo eqhelekileyo

Ububanzi

350 ukuya kwi-1500mm, ngamanye amaxesha nangaphezulu.

Ubunzima bodonga

I-8mm ukuya kwi-80mm, kuxhomekeke kwiqondo loxinzelelo lombhobho kunye namandla afunekayo omatshini.

Ubude

Iimitha ezi-6 ukuya kwi-12 yeemitha.Ubude bombhobho budla ngokulungiswa ngokweemfuno zabathengi kunye nezithintelo zokuhamba.

Iimpawu zokuSebenza zoMbhobho weNtsimbi we-SAWL

Amandla aphezulu oomatshini kunye nokuqina

iyakwazi ukumelana noxinzelelo oluphezulu kunye neendawo ezibuhlungu, ezifanelekileyo kwizicelo ezifuna amandla aphezulu.

Ukuchaneka okugqwesileyo komgangatho

inkqubo yokuvelisa echanekileyo iqinisekisa ukufana kobubanzi kunye nobukhulu bodonga, ukuphucula ukuthembeka okupheleleyo kwenkqubo yokubhobhoza.

Umgangatho olungileyo we-welding

I-arc welding ephantsi kwamanzi inciphisa i-oxidization phantsi kwempembelelo yokukhusela igesi kunye ne-flux, ukuphucula ukucoceka kunye namandla e-weld.

Ukumelana nomhlwa okuphezulu

unyango olongezelelweyo anti-corrosion kwenza ukuba ilungele uluhlu olubanzi lwemekobume, kubandakanywa submarine okanye imibhobho engaphantsi komhlaba.

Ifanelekile ukuthutha umgama omde

Amandla aphezulu kunye nokuzinza kwe-dimensional kwenza kube yinto efanelekileyo kwimibhobho yeoli kunye negesi yomgama omde.

Izicelo ze-SAWL Steel Pipe

Ezona zicelo zibalulekileyo zombhobho wensimbi we-SAWL unokushwankathelwa njengokuhambisa okuphakathi kunye nokusetyenziswa kolwakhiwo.

SAWL izicelo

Ukuhambisa imidiya

Imibhobho yentsimbi ye-SAWL ifaneleke ngokukodwa ukuthuthwa kweendaba ezifana neoli, igesi, namanzi.Ngenxa yeempawu zabo eziphezulu zoomatshini kunye nokumelana noxinzelelo oluphezulu, le mibhobho isetyenziswa ngokuqhelekileyo kumgama omde ongaphantsi komhlaba okanye kwimibhobho yokuthutha i-oyile kunye negesi kwi-submarine, kunye nokuhanjiswa kwamanzi ezidolophini nakwimizi-mveliso kunye neenkqubo zokuhambisa amanzi.

Amaqonga aselunxwemeni
