    a.Indlela ye-deoxidation yonyulwa ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto ezibophelelayo zenitrogen ngokwezixa ezaneleyo zokubopha initrogen ekhoyo (umz. min. 0,020 % iyonke iAl okanye i-0,015 % enyibilikayo iAl).

    b.Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukubunjwa kweekhemikhali kubonisa ubuncinane be-Al umxholo we-0,020 % kunye nomlinganiselo we-Al/N ubuncinane we-2: 1, okanye ukuba kukho ezinye izinto ezaneleyo ze-N-binding.Izinto ezibophelelayo ze-N ziya kubhalwa kuXwebhu loHlolo.

    Uvavanyo lweHydrostatic

    Ubude bombhobho ngamnye buya kuvavanywa ngumenzi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungekho ngaphantsi kwama-60% obona buncinci buchaziweyo bamandla esivuno kwindawo yobushushu begumbi.Uxinzelelo luya kumiselwa ngolu nxaki lulandelayo:
    P=2St/D

    Ukwahluka okuvumelekileyo kubunzima kunye nemilinganiselo

    Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bethiyori, kubalwe kusetyenziswa ubude bayo kunye nobunzima bayo ngeyunithi yobude.
    Idayamitha yangaphandle ayisayi kwahluka ngaphezu kwe-±1% ukusuka kwidayamitha yangaphandle echaziweyo
    Ubunzima bodonga nakweyiphi na indawo abuyi kuba ngaphezu kwe-12.5% ​​phantsi kobukhulu bodonga oluchaziweyo

    Umbhobho weHelical Welded

    1. Qonda umbhobho wentsimbi we-S235 JR:

    Umbhobho wentsimbi we-S235 JRngumbhobho we-spiral welding osetyenziswa kakhulu kwiinkqubo zemibhobho.Zenziwe ngentsimbi esemgangathweni ophezulu ngokuhambelana nemigangatho yamazwe ngamazwe, ukuqinisekisa ukuqina okuphezulu kunye namandla.Inkqubo yokuvelisa ibandakanya ukubunjwa okujikelezayo kweentsimbi zentsimbi eziqhubekayo, ezithi ke zidityaniswe kubude obufunwayo.Obu buchule bokwakha bubonelela ngemibhobho ngeenzuzo ezibalulekileyo ngaphezu kwemibhobho yomthungo yemveli.

    2. Izinto eziluncedo kulwakhiwo lwemibhobho edityanisiweyo:

    Ulwakhiwo oludityanisiweyo lweS235 JR Spiral Steel Pipe lubonelela ngeenzuzo ezininzi kwiinkqubo zemibhobho.Okokuqala, i-spiral weld seams eqhubekayo iphakamisa ukunyaniseka kwesakhiwo sombhobho, okwenza kube nzima ukumelana noxinzelelo lwangaphakathi nangaphandle.Esi sakhiwo siqinisekisa nokuba ukuhanjiswa komthwalo, ukunciphisa umngcipheko wokungaphumeleli kombhobho.Ukongezelela, i-spiral shape yombhobho isusa isidingo sokuqiniswa kwangaphakathi, ngaloo ndlela iphucula amandla okuhamba kunye nokunciphisa ilahleko yoxinzelelo ngexesha lokudluliselwa kwamanzi.Umphezulu oqhubekayo ongenamthungo wombhobho ojikelezayo unciphisa umngcipheko wokuvuza kwaye uphucula ukhuseleko kunye nokusebenza kakuhle kwenkqubo yemibhobho.

    3. Ukuphucula ukuqina kunye nokuguquguquka:

    I-S235 JR Spiral Steel Pipe inika ukuqina okuphezulu ngenxa yezinto zayo zokwakha ezikumgangatho ophezulu.Ziyakwazi ukumelana ne-corrosion, i-abrasion kunye neemeko zemozulu ezibi kakhulu, okwenza kube lula kwiintlobo ezahlukeneyo zezicelo ezibandakanya ukuthuthwa kweoli kunye negesi, iinkqubo zamanzi kunye neeprojekthi zeziseko.Ukuguquguquka kwale mibhobho kuvumela ukuba kube lula ukulungelelanisa ukuhlangabezana neemfuno ezithile zeprojekthi.Ukongezelela, kulula ukuyifaka kunye nokugcina, ukongeza ukongeza kwisibheno sabo kunye nokunceda ekubangeleni inkqubo ye-ductwork eneendleko eziphezulu kunye nexesha elifanelekileyo.

    4. Iinzuzo zokusingqongileyo kunye nozinzo:

    Ukutshintshela kwi-S235 JR umbhobho wensimbi ojikelezayo kwiinkqubo zemibhobho nako kunokuzisa iinzuzo ezibalulekileyo zokusingqongileyo.Ubomi babo obude kunye nokuchasana nokuthotywa kunciphisa imfuno yokutshintshwa rhoqo, okukhokelela ekukhutshweni kwekhabhoni encinci kunye nokunciphisa ukuveliswa kwenkunkuma.Ukongezelela, ukuphinda kusetyenziswe intsimbi kwenza le mibhobho ibe yindlela ezinzileyo ngokuhambelana nemigaqo yoqoqosho lwesetyhula.Ngokusebenzisa i-S235 JR imibhobho yentsimbi ejikelezayo, amashishini anokuqinisekisa indlela ehambelana nokusingqongileyo kunye nenoxanduva lokuthutha ulwelo, ngaloo ndlela ekhuthaza ikamva eliluhlaza.

    Isiphelo:

    Ukusetyenziswa kwe-S235 JR yombhobho wensimbi ojikelezayo kwiinkqubo zombhobho kunika uluhlu lweenzuzo ezibalulekileyo, kubandakanywa ukuqina, ukhuseleko kunye nokusebenza kakuhle.Ulwakhiwo oludityanisiweyo lwe-spiral luqinisekisa ingqibelelo yolwakhiwo kwaye lubonelela ngokunikezelwa kolwelo oluthembekileyo kumashishini ahlukeneyo.Ngokubandakanya ubugcisa obuphambili obufana nobu, sivula indlela yeenkqubo zokubhobhoza ezizinzileyo nezithembekileyo.
