Umgangatho & neBanga:
ASTM A53, Grade A/B/C,API 5L,PSL1,PSL2,GR.B/X42-X80,ASTM A795,ASTM A135,ASTM A252,GR.1/2/3,AWWA C200
▇ ▍ Inkcazo
Umbhobho wentsimbi odityanisiweyo wenziwa usebenzisa iipleyiti zentsimbi ezisicaba okanye imicu yentsimbi, kwaye inkqubo yayo yokuvelisa idala imithungo emzimbeni wayo.Ngokukodwa, xa kusenziwa imibhobho yentsimbi edityanisiweyo, ipleyiti yentsimbi okanye umcu uyagotywa kwaye emva koko udityaniswe ube setyhula, imilo yombhobho wesintu okanye imilo yesikwere. indlela ye welding.Umzekelo, umbhobho we-LSAW udityaniswe ngobude, kwaye umbhobho we-SSAW u-spiral-welding.Umbhobho we-ERW kuxhathiso lombane oludityanisiweyo, olukhokelela kumthungo ohamba ngokunxuseneyo ecaleni komzimba wombhobho.
▇ ▍Umbhobho weNtsimbi we-ERW
Imibhobho edityanisiweyo ene-high-frequency welded generally-slit-slit, kodwa imibhobho yentsimbi edityanisiweyo ethe tye ayinyanzelekanga ukuba idityaniswe isantya esiphezulu.I-high-frequency straight-slit resistance electric resistance welded steel pipe yenziwa yimpembelelo yesikhumba kunye nefuthe elikufutshane le-high-frequency yangoku emva kokuba ipleyiti ye-coil eshushu yenziwe ngumatshini wokubumba, kwaye umda we-tube ungenanto. kushushu kwaye kunyibilike, kunye noxinzelelo lwe-welding lwenziwa phantsi kwesenzo se-roller yokucofa ukuqonda imveliso.I-high-frequency resistance edityanisiweyo yombhobho wentsimbi yahlukile kwindlela eqhelekileyo yokudibanisa umbhobho.I-weld yenziwe ngesiseko somzimba wentsimbi, kwaye amandla omatshini angcono kunombhobho odibeneyo odibeneyo.Umphezulu ugudile, uchaneke kakhulu, ixabiso eliphantsi, kwaye unobude obuphantsi be-weld ye-weld, enenzuzo ekugqumeni kwe-3PE anti-corrosion coating.
▇ ▍Ipayipi yentsimbi ye-LSAW
Longitudinal submerged arc welded iveliswa ngokusebenzisa enye medium and thick plate as the raw material, ngokucinezela (rolling) ipleyiti yentsimbi ekubumbeni okanye kumatshini wokwenza umbhobho ongenanto, usebenzisa i-arc ye-arc enecala eliphindwe kabini, kunye nokwandisa ububanzi.Isixa sokutya kwepleyiti yentsimbi sinokuhlengahlengiswa ngokuzenzekelayo ngokwemigangatho eyahlukeneyo yentsimbi, ubukhulu bodonga, kunye nobubanzi bepleyiti.Ngelo xesha, umsebenzi wembuyekezo ye-deformation uthintela ngokufanelekileyo imiphumo emibi ye-mold deformation ekubunjweni kunye nokuqinisekisa ukunyanzeliswa kobude obupheleleyo bentsimbi yentsimbi ngexesha loxinzelelo.Isinyathelo sokutya siyafana ngexesha lokuqulunqa, ukuqinisekisa ukujikeleza kwetyhubhu engenanto kunye ne-flatness ye-welding edge.Imveliso egqityiweyo inoluhlu olubanzi lweenkcukacha, kwaye i-weld inokuqina okulungileyo, iplastiki, ukufana, kunye nokubumbana.Ineengenelo zobubanzi bombhobho omkhulu, ubukhulu bodonga lombhobho, ukumelana noxinzelelo oluphezulu, ukumelana nobushushu obuphantsi, kunye nokumelana nomhlwa okuqinileyo.
▇ ▍Umbhobho weNtsimbi we-SSAW
Umbhobho weSpiral welding (umbhobho we-SSAW, okwabizwa ngokuba ngumbhobho we-HSAW).Umbhobho wenziwa ngobuchwephesha be-arc welding ye-spiral submerged arc.Imibhobho ye-Spiral welded yenziwa kusetyenziswa iipleyiti ezincinci okanye iikhoyili ezishushu eziqengqelekayo, ezithoba iindleko zabo zemveliso kakhulu.Umgca we-welding ufana ne-helix.Inkqubo yokudibanisa i-spiral ivumela ukuveliswa kwemibhobho yobubanzi obukhulu obufanelekileyo ukuthutha umthamo omkhulu weoli kunye negesi.Eminye imibhobho ye-SSAW yayikhawulelwe ngokwembali kwizicelo zoxinzelelo oluphantsi.
