Ukuhlolwa kwezinto eziluhlaza (iKhoyili):Iikhoyili zentsimbi ezingenayo ezigoqwe ngobushushu ziqinisekisiwe ukuba zenziwe ngamakhemikhali, iimpawu zoomatshini, kunye nomgangatho womphezulu ngokuchasene nemigaqo ye-ASTM A500 GR.B. 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 ze-arc eziphantsi komhlaba ezizenzekelayo kunye nomxube ofanelekileyo we-flux kunye nocingo.
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.
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 ngokubonakalayo kweziphene zomphezulu, ukuqinisekiswa kobukhulu (OD, WT, ubude, ukuthe tye, ukujikeleza), kunye nophawu olusisigxina ngokwe-ASTM A500 (kubandakanya inqanaba, ubungakanani, inombolo yobushushu, ukuchongwa komenzi).

Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo) - Umbhobho Wolwakhiwo we-ASTM A500 GR.B SSAW
Q: Yintoni umahluko phakathi kwe-ASTM A500 GR.B kunye ne-ASTM A252 GR.3?
A: I-ASTM A500 GR.B inamandla okuvelisa ubuncinane angama-315 MPa, ngelixa i-ASTM A252 GR.3 ine-345 MPa. I-A500 GR.B inomlinganiselo oqinileyo kwaye yenzelwe ukwakheka kwesakhiwo. I-A252 GR.3 yenzelwe ngokukodwa ukufakwa kwezakhelo kunye nokuqhuba. I-A500 GR.B inika ubude obuphezulu (23% vs 20%), nto leyo ebonisa ukuba i-ductility ingcono xa isenziwa.
Q: Ngaba i-ASTM A500 GR.B ingasetyenziselwa ukufaka iipali?
A: Ewe, i-ASTM A500 GR.B ingasetyenziselwa ukufakela iipali, ingakumbi kwiimfuno zesiseko esilula. Nangona kunjalo, kwiipali ezinzima zasemanzini nakwiziseko ezinzulu, i-ASTM A252 GR.3 okanye i-EN 10248 S355GP iyacetyiswa ngenxa yamandla azo aphezulu kunye neemfuno ezithile zokuqhuba.
Q: Ingakanani ubude obuphezulu bombhobho wesakhiwo se-ASTM A500 GR.B SSAW?
A: Ubude obuqhelekileyo yi-6m, 12m, kunye ne-18m. Ubude obulungiselelwe wena ukuya kuthi ga kwi-60m buyafumaneka ngokuxhomekeke kububanzi kunye nobukhulu bodonga.
Q: Zeziphi iindlela zokugqiba umphezulu ezikhoyo?
A: Sinikezela ngeengubo ezingenanto (isikali semill), ezifakwe ioyile, ezifakwe iprime, ezifakwe i-black coat, ezifakwe i-hot dip galvanised, kunye neengubo ezahlukeneyo ezichasene nokugqwala.
Q: Ngaba ungabonelela ngemibhobho yolwakhiwo ngokuhlolwa ngumntu wesithathu?
A: Ewe. Siququzelela uhlolo lwe-SGS, i-BV, i-TÜV, i-DNV, okanye nawuphi na ummeli otyunjwe ngumthengi.
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.
