    ASTM A234 Longitudinal Welded Umbhobho obonakalayo Umfanekiso
    • ASTM A234 Longitudinal Welded Umbhobho

    Inkcazelo emfutshane:

    Ukuqonda umahluko ophambili kunye neenzuzo zohlobo ngalunye kunokunceda abathengi benze isigqibo esinolwazi.Kule post yebhlog, siza kuntywila nzulu kwiimpawu zombhobho we-LSW, sigxile kwiimpawu zabo ezizodwa kunye nokusetyenziswa.

    Iithegi zeMveliso

    Yazisa:

    Ehlabathini lemibhobho yensimbi, ibinzana eliqhelekileyo liza rhoqo: umbhobho we-welded longitudinally.Le mibhobho idlala indima ebalulekileyo kumashishini ahlukeneyo kwaye isebenza ngeenjongo ezahlukeneyo.

    Umbhobho welongitudinal welding, ekwaziwa ngokuba yi-straight seam welded pipe, ngumbhobho wentsimbi owenziwe ngepleyiti yentsimbi eshushu okanye ebandayo okanye i-coil strip yensimbi.Igama labo livela kwinkqubo ye-welding, eyenzeka kumgca ochanekileyo kunye nobude bombhobho.Le ndlela iqinisekisa umgangatho we-weld ongaguqukiyo kunye namalungu aqinile, ukuthintela ukuvuza kunye nokuphucula imfezeko yesakhiwo ngokubanzi.

    Umbhobho weLsaw Line

    Umbhobho odityanisiweyo wexesha elide:

    Kwelinye icala,imibhobho edityanisiweyo ngokuthe ngqozenziwa kusetyenziswa iindlela ezahlukeneyo zokuwelda ezifana ne-arc welding okanye i-resistance welding.Le mibhobho idla ngokwenziwa kwimibhobho engenamthungo okanye i-welded tube blanks, ethi ke ibunjwe ngendlela efunwayo.I-Longitudinal Welded Pipe inika amandla akhethekileyo kunye nokuqina, iyenza ilungele usetyenziso lweshishini olubandakanya iimeko zoxinzelelo oluphezulu okanye imithwalo enzima.

    Imibhobho edityanisiweyo ye-longitudinal ingena kwinkqubo ye-welding echanekileyo yokuqinisekisa ubuninzi bodonga olufanayo kuwo wonke umbhobho kunye neziphene ezincinci.Oku kubenza babe lolona khetho lubalaseleyo kusetyenziso lwesakhiwo esifana nolwakhiwo, isikafula kunye nokufaka inqwaba.

    Imibhobho edityanisiweyo ethe tye, kwelinye icala, iza kwiimilo ezahlukeneyo kunye nobukhulu.Inkqubo yabo yokuvelisa ivumela ukwenza ngokwezifiso, ibenze bafanelekele izicelo ezifuna imilinganiselo ethile okanye uyilo olunzima.Ukongeza, imibhobho edityaniswe ixesha elide isetyenziswa kakhulu kumashishini afana neoyile kunye negesi, iimoto, kunye ne-aerospace ngenxa yamandla abo aphezulu kunye nokumelana noxinzelelo.

    Ubungcali beNkampani:

    Ukuba ujonge iiPipe zeLSW ezithembekileyo, iCangzhou Spiral Steel Pipe Group Co., Ltd. ligama elithembekileyo kushishino.Inkampani inemizila ye-13 ekhethekileyo yokuvelisa imibhobho yensimbi ejikelezayo, imigca ye-4 yokuvelisa i-anti-corrosion kunye nokugcinwa kobushushu, kwaye inobuchwepheshe obuchwephesha kunye nezixhobo ezifunekayo ukuveliswa kwemibhobho yensimbi ephezulu.

    Ukuququmbela:

    Isishwankathelo, umbhobho odityanisiweyo othe ngqo ubonelela ngeenzuzo ezizodwa ngokuxhomekeke kwiimfuno ezithile zeprojekthi okanye isicelo sakho.Umbhobho we-Welded we-Longitudinal ume ngaphandle komgangatho we-weld ongaguqukiyo kunye nozinzo lwesakhiwo, ngelixa i-Longitudinal Welded Pipe inikezela ngeendlela ezahlukeneyo kwimilo kunye nobukhulu.Ngokuqonda ezi yantlukwano, unokwenza isigqibo esinolwazi xa ukhetha imibhobho elungele iimfuno zakho.Ngomgangatho kunye nokuthembeka, thembela iCangzhou Spiral Steel Pipe Group Co., Ltd., inkampani ezinikele ekugqweseni kwimveliso yentsimbi yombhobho.
