Ukuqonda ukubaluleka kombhobho wegesi yendalo yendalo: I-X42 SSAW PIP, i-ASTM A139 ne-En10219

Ukuqonda ukubaluleka komgangatho wegesi yendalo: I-X42 SSAW PIP, i-ASTM A139 kunye ne-En10219 ibonakalise umfanekiso

Inkcazo emfutshane:

Xa kufikwa kuhambo lwegesi yegesi, iinkqubo zepayipi zidlala indima ebalulekileyo ekuqinisekiseni ukuhanjiswa okukhuselekileyo nangokufanelekileyo kolu phononongo luxabisekileyo.umbhobho wegesi yendalo Ukukhetha isigqibo esibalulekileyo njengoko kuchaphazela ngokuthe ngqo ukuthembeka kunye nokhuseleko lwenethiwekhi yokuhambisa irhasi. Kwezi bhlog, siya kukhusela kubaluleke kwi-pipe esemgangathweni yendalo, egxile kumbhobho we-X42 SSAW, i-ASTM A139, ne-En10219.

Iimpawu zeMveliso

X42Ssawumbhobholuhlobo lombhobho wegesi wendalo oqhele ukusetyenziswa kwishishini leoyile negesi. Ifakelwe kusetyenziswa inkqubo ye-arc ye-welc ye-arc evelisa imibhobho yomgangatho ophezulu kunye neyemidlalo. I-X42 SSAW PIP inamandla aphezulu kunye nezinto ezibalaseleyo zekhemikhali, zisenza ilungele iimfuno ezifunwayo zothutho lwegesi yendalo. Ukuchasana nokuchasana nokungavisisani kokusula kwaye ukuqhekeka kwenza ukhetho lokuqala lweeprojekthi zokwakha zepayiphu.

I-ASTM A139ngomnye umgangatho obalulekileyo kwimibhobho yegesi yendalo. Oku kuchazwa kubandakanya i-ElectroFusion (i-ARC) ye-Weldied ngqo okanye i-Spiral Seam Seam esetyenziselwa ukudlulisela igesi, i-steam, amanzi kunye nolunye ulwelo. I-ASTM A139 I-Pipe yaziwa ngokunyaniseka kwayo kunye nokusebenza kwexesha elide phantsi kweemeko zokusebenza. Le mibhobho yenzelwe ukumelana neengcinezelo eziphezulu kunye nokuguquguquka kobushushu, kubenza balungele ukuhambisa irhasi yendalo kunye nokuhambisa.

En10219Ngumgangatho we-European ochaza iimeko zobugcisa zokuhambisa ubuchule bokwexesha olwenziwe nge-welding ye-welding ye-nelded yentsimbi yentsimbi kunye nentsimbi entle. Nangona i-En10219 ayilungelelaniswanga ngqo kwimibhobho yegesi yendalo, iimfuno zayo ezinqabileyo zokuhlala, ukuchaneka kokuchaneka kunye neepropathi zoomatshini kuyenza lukhetho olufanelekileyo lweeprojekthi ezithile zegesi. Ukusebenzisa imibhobho ethobela imigangatho ye-En10219 inokuphucula ingqibelelo kunye nobomi benkonzo yenkqubo yakho yokufumana irhasi yendalo.

Ukubaluleka kokukhetha umbhobho wegesi yendalo ayinakuphela. Imigangatho esemgangathweni okanye imibhobho engaphantsi komhlaba inokubangela umngcipheko omkhulu kwindalo, ukhuseleko loluntu kunye nokuthembakala kwegesi. Ke ngoko, izinto zerhasi yendalo, abaqhubi beegesi kunye nabaphathi beeprojekthi kufuneka babeka phambili ukusetyenziswa kwemibhobho ye-piped kunye ne-pipeliped eqingqiweyo njenge-X42 SSAW, i-A1319191919.

Isishwankathelo,umbhobho wegesi yendaloUkukhetha yinkalo ebalulekileyo yoyilo kunye nolwakhiwo. Ukuqwalaselwa komgangatho, njengamandla ezinto, ukunganyangeki, kunye nokuthobela imigangatho yeshishini, kufuneka iqhube inkqubo yokwenza izigqibo. Ngokukhetha imibhobho ethembekileyo neyamkelweyo, efana ne-X42 SSAW i-X42 SSAWEL, i-ASTM A139, kunye ne-En10219, abathathi-nxaxheba banokuqinisekisa ukusetyenzwa kwexesha elide kunye nokhuseleko lwezibonelelo zendalo zegesi.

Okokugqibela, kubalulekile ukuba ubeke phambili ukusetyenziswa kwemibhobho yegesi ephezulu yendalo evumela ukuhlangabezana nemigangatho yemizi-mveliso kwaye unemimandla eyimfuneko kunye neekhemikhali. Ngokukhetha iindlela ezinokuthenjwa ezinjenge-X42 SSAW PIPIPEL, i-ASTM A139 kunye ne-En10219, abaqhubi beepyline banokuqinisekisa intembeko yexesha elide kunye nokukhuseleka kweenkqubo zabo zokuhambisa irhasi.
