    Ukuqonda ukubaluleka koMgangatho weMibhobho yeGesi yeNdalo: X42 SSAW Pipe, ASTM A139 kunye ne-EN10219 Umfanekiso ofakiweyo
    • Ukuqonda ukubaluleka koMgangatho weGesi yeNdalo yombhobho: X42 SSAW Pipe, ASTM A139 kunye EN10219

    Inkcazelo emfutshane:

    Xa kuziwa ekuthuthweni kwerhasi yendalo, iinkqubo zemibhobho zidlala indima ebalulekileyo ekuqinisekiseni ukuhanjiswa okukhuselekileyo nokufanelekileyo kobu butyebi buxabisekileyo.umbhobho wegesi yendalo ukhetho luyisigqibo esibalulekileyo njengoko sichaphazela ngokuthe ngqo ukuthembeka kunye nokhuseleko lwenethiwekhi yonke yokusabalalisa igesi.Kule bhlog, siza kuhlolisisa ukubaluleka komgangatho wombhobho wegesi yendalo, sigxile kwi-X42 SSAW pipe, ASTM A139, kunye ne-EN10219.


    Iinkcukacha zeMveliso

    Iithegi zeMveliso

     X42SSAWumbhobholuhlobo lombhobho werhasi yendalo edla ngokusetyenziswa kwishishini leoli negesi.Iveliswa ngokusebenzisa inkqubo ye-arc welding ephantsi kwamanzi evelisa umgangatho ophezulu kunye nemibhobho ehlala ixesha elide.Umbhobho we-X42 we-SSAW unamandla aphezulu kunye neempawu zekhemikhali ezigqwesileyo, ziyenza ifaneleke ngokufanelekileyo iimfuno ezifunekayo zothutho lwegesi yendalo.Ukuxhathisa kwayo ngokugqwesileyo kwi-corrosion kunye nokuqhekeka kwenza kube yinto yokuqala yokukhetha iiprojekthi zokwakha imibhobho.

     I-ASTM A139ngomnye umgangatho obalulekileyo kwimibhobho yegesi yendalo.Le nkcazelo igubungela i-electrofusion (i-arc) umbhobho wentsimbi odityaniswe ngokuthe ngqo okanye ojikelezayo osetyenziselwa ukuhambisa iigesi, umphunga, amanzi kunye nolunye ulwelo.Umbhobho we-ASTM A139 uyaziwa ngokuthembeka kunye nokusebenza kwexesha elide phantsi kweemeko ezinzima zokusebenza.Le mibhobho yenzelwe ukujamelana noxinzelelo oluphezulu kunye nokuguquguquka kweqondo lokushisa, okwenza kube yinto efanelekileyo yokuhanjiswa kwegesi yendalo kunye nokuhanjiswa kwezicelo.

     EN10219ngumgangatho waseYurophu ochaza iimeko zokuhanjiswa zobugcisa kumacandelo angaphakathi adityanisiweyo adityanisiweyo entsimbi engeyiyo ialloyi kunye nentsimbi ecolekileyo.Nangona i-EN10219 ingenzelwanga ngokukodwa imibhobho yerhasi yendalo, iimfuno zayo ezingqongqo zokuqina, ukuchaneka komgangatho kunye neempawu zoomatshini ziyenza ibe lukhetho olufanelekileyo kwiiprojekthi ezithile zemibhobho yerhasi.Ukusebenzisa imibhobho ehambelana nemigangatho ye-EN10219 kunokuphucula yonke imfezeko kunye nobomi benkonzo yenkqubo yakho yokuhambisa igesi yendalo.

    Ukubaluleka kokukhetha umgangatho wepayipi yegesi yendalo ayikwazi ukugqithiswa.Imibhobho ekumgangatho ophantsi okanye engekho mgangathweni inokubeka imingcipheko ebalulekileyo kokusingqongileyo, ukhuseleko loluntu kunye nokuthembeka okupheleleyo kokunikezelwa kwegesi.Ke ngoko, izixhobo zerhasi yendalo, abaqhubi bemibhobho kunye nabaphathi beprojekthi kufuneka babeke phambili ukusetyenziswa kwezixhobo zemibhobho eziqinisekisiweyo nezisekwe kakuhle ezifana nombhobho we-X42 SSAW, i-ASTM A139 kunye ne-EN10219.

    Umbhobho we-SSAW

    Isishwankathelo,umbhobho wegesi yendaloukhetho luyinkalo ebalulekileyo yoyilo lombhobho kunye nokwakhiwa.Ukuqwalaselwa komgangatho, njengamandla ezinto eziphathekayo, ukuxhathisa ukubola, kunye nokuthotyelwa kwemigangatho yoshishino, kufuneka kuqhube inkqubo yokwenza izigqibo.Ngokukhetha imibhobho ethembekileyo nethembekileyo, efana nombhobho we-X42 SSAW, i-ASTM A139, kunye ne-EN10219, abachaphazelekayo banokuqinisekisa ukusebenza kwexesha elide kunye nokhuseleko lweziseko zokuthutha igesi yendalo.

    Okokugqibela, kubalulekile ukubeka phambili ukusetyenziswa kwemibhobho yegesi yendalo ekumgangatho ophezulu ehlangabezana nemigangatho yoshishino kwaye ineempawu eziyimfuneko zoomatshini kunye neekhemikhali.Ngokukhetha iinketho ezithembekileyo ezifana nombhobho we-X42 SSAW, i-ASTM A139 kunye ne-EN10219, abaqhubi bemibhobho banokuqinisekisa ukuthembeka kwexesha elide kunye nokhuseleko lweenkqubo zabo zokuhambisa igesi yendalo.
