ERW Welding Round Steel Imibhobho

Inkcazelo emfutshane:

Imibhobho engqukuva edityanisiweyo ye-ERW ikwabizwa ngokuba yimibhobho edityanisiweyo yokumelana.Olu hlobo lombhobho wentsimbi oludityanisiweyo lusetyenziswa kakhulu kwiinkalo ezahlukeneyo ezifana nobunjineli, ukubiyela, ukukhahlela, imibhobho yomgca, njl njl. Imibhobho yentsimbi edityanisiweyo ye-ERW ifumaneka kwiimpawu ezahlukeneyo, ubukhulu bodonga kunye needamitha zombhobho ogqityiweyo.

Intshayelelo yeMveliso

Iityhubhu zokumelana nombane ezidityanisiweyo (ERW) zenziwe ngokubanda zenza umtya wentsimbi osicaba ube ityhubhu engqukuva kwaye igqithise kuthotho lwemiqulu yokubumba ukufumana i-weld yobude.Imiphetho emibini ke ifudunyezwe ngaxeshanye kunye ne-high-frequency current kwaye idityaniswe kunye ukwenza ibhondi.Akukho ntsimbi yokuzalisa efunekayo kwi-welds ye-ERW emide.

Akukho zinyithi ezidityanisiweyo ezisetyenziswa ngexesha lenkqubo yokuvelisa.Oku kuthetha ukuba umbhobho womelele kakhulu kwaye womelele.

I-weld seam ayinakubonwa okanye ivakalelwe.Lo ngumahluko omkhulu xa ujonga inkqubo ye-arc entywiliselwe kabini, eyenza i-welded bead ecacileyo enokufuna ukupheliswa.

Ngokuhambela phambili kwimisinga yombane ejikelezayo kwi-welding, inkqubo ilula kakhulu kwaye ikhuselekile.

Iibhobho zentsimbi ze-ERW zenziwe nge-low-frequency okanye i-high-frequency resistance resistance "ukumelana".Ziyimibhobho engqukuva edityaniswe kwiipleyiti zentsimbi ezinemibhobho yobude.Isetyenziselwa ukuthutha ioyile, igesi yendalo kunye nezinye izinto zolwelo lomphunga, kwaye inokuhlangabezana neemfuno ezahlukeneyo zoxinzelelo oluphezulu noluphantsi.Okwangoku, ikwindawo ebalulekileyo kwimibhobho yothutho ehlabathini.

Ngexesha le-ERW ye-welding ye-welding, ubushushu buveliswa xa ikhoyo ngoku ihamba kwindawo yokudibanisa yendawo ye-welding.Itshisa imiphetho emibini yentsimbi ukuya kwindawo apho umgca omnye unokwenza ibhondi.Ngelo xesha, phantsi kwesenzo soxinzelelo oludibeneyo, imida ye-tube engenanto iyanyibilika kwaye idibanise.

Ngesiqhelo umbhobho we-ERW ubuninzi be-OD ngama-24" (609mm), kumlinganiselo omkhulu wombhobho uya kwenziwa kwi-SAW.

Umboniso weMveliso

Loluphi uhlobo lwemibhobho (imigangatho) enokwenziwa kwiinkqubo ze-ERW?

Mininzi imibhobho enokwenziwa ngenkqubo ye-ERW.Apha ngezantsi sidwelisa imigangatho eqhelekileyo kwimibhobho.

Umbhobho wentsimbi yeCarbon kwi-ERW.

I-ASTM A53 iBanga A kunye no-B (kunye neGalvanized).

I-ASTM A252 ingqumba yombhobho.

ASTM A500 ityhubhu yesakhiwo.

ASTM A134 kunye ASTM A135 umbhobho.

EN 10219 S275, S355 umbhobho.

API ERW Line Umbhobho

I-API 5L B ukuya ku-X70 PSL1 (PSL2 iya kuba kwinkqubo ye-HFW)

I-API 5CT J55 / K55, i-N80 casing kunye ne-tubing kunye nokunye.

Ukusetyenziswa kombhobho wentsimbi ye-ERW:
Umbhobho wensimbi we-ERW osetyenziselwa ukuthutha igesi kunye nezinto ezingamanzi ezifana ne-oyile negesi, unokuhlangabezana nemfuneko yoxinzelelo oluphantsi noluphezulu.Kwiminyaka yakutshanje, kunye nophuhliso lobuchwepheshe ERW, ngakumbi nangakumbi ERW umbhobho yentsimbi esetyenziswa emasimini oyile negesi, ishishini lemoto njalo njalo.

Izinto ezilungileyo zombhobho we-ERW:
Ukusebenza okuphezulu, ixabiso eliphantsi, ukugcinwa kwezinto eziphathekayo, ukuzenzekelayo okulula.
