Ukuhlolwa kwezinto eziluhlaza (iKhoyili):Iikhoyili zentsimbi ezingenayo ezigoqwe ngobushushu ziqinisekisiwe ukuba zenziwe ngamakhemikhali, iimpawu zoomatshini, kunye nomgangatho womphezulu ngokuchasene neenkcukacha ze-ASTM A572 GR.50. Ikhoyili nganye inikwe inombolo yobushushu eyahlukileyo ukuqinisekisa ukulandeleka ngokupheleleyo kwezinto kuyo yonke imveliso.
Ukuvula kunye nokulinganisa:Iikhoyili zentsimbi zifakwa kwi-uncoiler kwaye zifakwe ngomatshini wokulinganisa ngokuchanekileyo ukuze zithe tyaba umcu, zisuse iseti yeekhoyili kwaye ziqinisekise ukuba zithe tyaba ngokulinganayo ukuze kubekho ukwakheka okujikelezayo okuhlala kusenzeka.
Ukusila kunye nokuSika imiphetho:Zombini imiphetho emide yomcu wentsimbi iyasilwa kwaye inqunyulwe ukuze ifikelele kububanzi obuchanekileyo (± 0.5mm). Ukulungiswa komphetho kudala umphezulu ococekileyo, ohambelanayo obalulekileyo ekwakhiweni kwe-spiral weld esemgangathweni ophezulu.
Ukwakheka kweSpiral:Umcu olinganisiweyo ufakwa kumatshini owenza i-spiral kwi-engile ye-helix elawulwayo. Umcu uhlala usenziwa ube yi-spiral cylindrical shape, kunye nemiphetho elungelelaniswe ukuze kudityaniswe.
Ukuwelda kwe-Arc efakwe ngaphakathi emanzini (i-SAW):Umthungo wangaphakathi ojikelezayo udityaniswa kuqala kusetyenziswa izixhobo zokuwelda eziphantsi komhlaba ezizenzekelayo kunye nomxube ofanelekileyo we-flux kunye nocingo. Kwintsimbi enamandla aphezulu, izinto ezikhethekileyo ezisetyenziswayo zokuwelda zisetyenziselwa ukuhambelana neempawu zesinyithi ezisisiseko.
Ukuwelda kwe-Arc engaphantsi kwamanzi (i-SAW) yangaphandle:Umthungo wangaphandle ojikelezayo udityaniswa kwangoko emva kwe-inner weld, kusetyenziswa izixhobo zokuwelda ze-arc eziphantsi komhlaba ezizenzekelayo.
Ukusika Ubude:Umbhobho odibeneyo ojikelezayo oqhubekayo unqunyulwa ngobude obuchaziweyo kusetyenziswa iinkqubo zokusika i-plasma okanye i-oxygen ezizenzekelayo.
Uvavanyo Olungonakalisiyo (NDT):
Uvavanyo lwe-Ultrasonic oluyi-100% (UT):Inkqubo ye-UT ezenzekelayo ihlola yonke i-spiral weld seam kunye nomzimba wephayiphi epheleleyo ukuze ibone ukuba kukho ii-laminations, izinto ezifakiweyo, ukungabikho kwe-fusion, kunye nezinye izinto ezingahambelaniyo.
Uvavanyo lweRadiographic (RT):Ukuhlolwa kwe-X-reyi okanye i-gamma-reyi yomthungo we-weld (indawo okanye ubude obupheleleyo njengoko kuchaziwe).
Uhlolo lweeNgcawu zeMagnetic (MPI):Ukuhlolwa kweenzwane ze-weld kunye nendawo echaphazeleka bubushushu ukuze kujongwe imifantu yomphezulu kunye nokungaqhubeki kwawo.
Uvavanyo lwe-Hydrostatic (Ukhetho):Iyafumaneka xa umthengi ecela.
Ukugqiba Ukugqiba:Iziphelo ezingenanto (ezisikwele) okanye iziphelo ezibekiweyo (i-angle ye-bevel engama-30°-35°) ngokweemfuno zomthengi.
Uhlolo lokugqibela kunye nokumakishwa:Ukuhlolwa okubonakalayo kweziphene zomphezulu, ukuqinisekiswa kobukhulu (OD, WT, ubude, ukuthe tye, ukujikeleza), kunye nophawu olusisigxina ngokwe-ASTM A572 (kubandakanya inqanaba, ubungakanani, inombolo yobushushu, ukuchongwa komenzi).

Iintloko zokuphela:Izigqubuthelo zeplastiki okanye zentsimbi zikhusela iziphelo ezigobileyo kunye neziphelo ezingenanto ekonakalisweni yingxwabangxwaba, ukungena kwenkunkuma kunye nokufuma.
Ukugquma kunye nokugquma:Kwiiodolo zokuthumela ngaphandle ezikumgangatho ophezulu, kusetyenziswa izinto zokugquma ezifana neeringi zefoam, imicu yerabha, okanye i-dunnage yomthi phakathi kweengqimba zepayipi.
Ukuhambisa ngenqanawe:
Indlela Yothutho:Iipayipi zithunyelwa ngeenqanawa zesikhongozeli (izikhongozeli ezingama-20ft okanye ezingama-40ft kwiidayamitha ezincinci), iithwali ezinkulu (ziqhekeza inqwaba kwiidayamitha ezinkulu kunye nomthamo omkhulu), okanye imithwalo kaloliwe.
Ukufakwa kwiikhonteyina (Ububanzi obuncinci):Kwimibhobho emincinci enobubanzi (ngesiqhelo ingaphantsi kwe-508mm / 20"), imibhobho ifakwa kwiikhonteyina zokuhambisa ezisemgangathweni ezingama-20ft okanye ezingama-40ft.
Ukulayisha iinqanawa ezinkulu (Ububanzi obukhulu kunye nomthamo omkhulu):Kwiiodolo ezinkulu (ngesiqhelo ezingaphezulu kweetoni ezingama-500) okanye iipayipi ezinkulu ezinobubanzi obungaphezulu kwe-508mm / 20"), iipayipi zilayishwa ngqo kwiinqanawa zokuthwala izinto ezinkulu okanye kwiinqanawa ezifakelwe iigiya.
Izikhongozeli zeRakhi eSicaba okanye eziVulekileyo eziphezulu:Kwimibhobho edlula ubungakanani obuqhelekileyo besikhongozeli (ubude >12m okanye ububanzi >2.3m), izikhongozeli zerack ezisicaba okanye izikhongozeli eziphezulu ezivulekileyo zingasetyenziswa.
Ukubhala iilebheli kunye noxwebhu:Iphakheji nganye okanye umbhobho ngamnye ubhalwe ngokucacileyo ngolwazi olubalulekileyo oluquka umgangatho wezinto, umgangatho, ubukhulu, inombolo yobushushu, inombolo yephakheji/umbhobho, kunye nemiyalelo yokuphatha.
Ukuthobela iMithetho yezeMali:Zonke iimpepha zerhafu ezifunekayo—i-invoyisi yorhwebo, uluhlu lokupakisha, i-invoyisi yemithwalo, iSatifikethi seMvelaphi, iiSatifikethi zoVavanyo lweMill—ziyalungiswa.
Ukubopha Okukhuselekileyo:Iibhanti kunye neepayipi nganye nganye zibotshelelwa ngokukhuselekileyo kusetyenziswa imitya yentsimbi (enezikhuseli zeekona), iingxowa ze-dunnage, izixhaso zeenkuni, okanye imitya yetyathanga ukuthintela intshukumo ngexesha lokuhamba.
Ukulandelela kunye nokuBeka esweni:Iinkqubo zokulandelela izinto eziphambili zibonelela ngohlaziyo lwendawo ngexesha langempela.
I-inshurensi:I-inshurensi yempahla yolwandle (Yonke Ingozi okanye Ngomgqumo oPhakathi) ingalungiselelwa.
Ngamafutshane, iWomic Steel iqinisekisa ukuba zonke iipayipi zentsimbi ezinamandla aphezulu ze-ASTM A572 GR.50 SSAW zipakishwe ngamanyathelo okukhusela aphambili kushishino kwaye zithunyelwa kusetyenziswa iindlela zothutho ezinokuthenjwa.

Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo) - Ipayipi Yentsimbi ye-ASTM A572 GR.50 SSAW
Q: Yintoni umahluko phakathi kwentsimbi ye-ASTM A572 GR.50 kunye nentsimbi ye-A36?
A: I-ASTM A572 GR.50 inamandla okuvelisa ubuncinane angama-345 MPa (50,000 psi), ngelixa i-A36 ine-250 MPa (36,000 psi). I-GR.50 inika amandla okuvelisa aphezulu angama-38%, okuvumela izakhiwo ezikhaphukhaphu kunye nobukhulu obuncitshisiweyo becandelo. I-GR.50 ikwaphucule ukumelana nokugqwala emoyeni ngenxa yokwakheka kwayo kwe-HSLA.
Q: Ngaba i-ASTM A572 GR.50 ingadityaniswa ngokusebenzisa iinkqubo eziqhelekileyo?
A: Ewe, i-ASTM A572 GR.50 inokudityaniswa kakuhle. Nangona kunjalo, ngenxa yamandla ayo aphezulu kunye nomxholo we-alloy (i-columbium kunye ne-vanadium), iinkqubo zokudityaniswa kwe-hydrogen ephantsi ziyacetyiswa. Ukufudumeza kungafuneka kwiindawo ezityebileyo. I-Womic Steel inokubonelela ngeengcebiso zenkqubo yokudityaniswa kwe-welding xa iceliwe.
Q: Yintoni umahluko phakathi kwe-ASTM A572 GR.50 kunye ne-ASTM A992?
A: I-ASTM A572 GR.50 yinkcazo ngokubanzi yeepleyiti zentsimbi ze-HSLA, iimilo, kunye neebhari. I-ASTM A992 yenzelwe ngokukodwa imiqadi ebanzi kunye neemilo zesakhiwo zokwenza iifreyimu zesakhiwo. Zombini zinamandla afanayo okuvelisa (345-450 MPa), kodwa i-A992 inolawulo oluqinileyo kwiipropati zezinto ezisetyenziswayo kwiintshukumo zenyikima.
Q: Bungakanani ubude obuphezulu bombhobho wentsimbi we-ASTM A572 GR.50 SSAW?
A: Ubude obuqhelekileyo yi-6m, 12m, kunye ne-18m. Ubude obulungiselelwe wena ukuya kuthi ga kwi-60m buyafumaneka ngokuxhomekeke kububanzi kunye nobukhulu bodonga. Ubude obude kakhulu bufanelekile kwiibhrorho kunye nokusetyenziswa kwesakhiwo esihlala ixesha elide.
Q: Zeziphi iindlela zokugqiba umphezulu ezikhoyo zokusetyenziswa kwebhulorho?
A: Kwizicelo zebhulorho, sinikezela nge-primer coating, i-hot dip galvanizing, okanye iinkqubo ezikhethekileyo zokulwa nokugqwala (i-FBE, i-3LPE, okanye i-epoxy coating). Intsimbi ye-Weathering (ASTM A588) ikwafumaneka kwizicelo zebhulorho ezifuna ukumelana nokugqwala emoyeni ngaphandle kokupeyinta.
Q: Ngaba ungawunika umbhobho we-ASTM A572 GR.50 ngokuhlolwa ngumntu wesithathu?
A: Ewe. Siququzelela uhlolo lwe-SGS, BV, TÜV, DNV, ABS, LR, okanye nawuphi na ummeli otyunjwe ngumthengi ngexesha lokuvelisa nangaphambi kokuthunyelwa. 3.2 Izatifikethi zokuhlola zinikezelwa rhoqo xa ziceliwe.
Q: Ngawaphi amaxwebhu anikezelwayo ngokuthunyelwa ngakunye?
A: Isatifikethi sovavanyo lweMill (EN 10204 Uhlobo 3.1), Ingxelo yoHlolo olunemilinganiselo, iingxelo ze-UT, iingxelo ze-RT (ukuba zichaziwe), amaxwebhu okulandelela, uluhlu lokupakisha, i-invoyisi yorhwebo, kunye nesatifikethi semvelaphi.
