Imibhobho ye-Spiral Seam yemibhobho yamanzi aphambili

Imibhobho ye-Spiral Seam yemibhobho yamanzi ephambili iboniswe umfanekiso

Inkcazo emfutshane:

Ukusebenza kweziseko zophuhliso, izixhobo ezisetyenzisiweyo zidlala indima ebalulekileyo kwi-ongetion kunye nokusebenza kweprojekthi. Isixhobo esinye esibaluleke kakhulu kushishino lwezibonelelo yimibhobho ye-Weldil ye-spild. Le mibhobho idla ngokusetyenziswa kwizicelo ezahlukeneyo ezinjengeendawo ezinamanzi kunye nemibhobho yegesi, kunye neenkcazo zabo, kuquka imibhobho ye-welded kunye ne-spiled seam seam, zibalulekile ekuqinisekiseni ukusebenza kwabo. Kule bhlog, siya kuthatha i-inI-Spiral Deped Pide nokubaluleka kwabo kumzi-mveliso wokwakha.

Iimpawu zeMveliso

SI-Piral Seam Pipeszakhiwe kusetyenziswa indlela ebizwa ngokuba yinkqubo yokuphucula i-spill yelding. Inkqubo ibandakanya ukusebenzisa imithwalo eshushu eshushu yentsimbi ukuba yenziwe ibe yimo ye-cylindrical kwaye emva koko idlwengule ecaleni komthungo weSpily. Iziphumo ngumbhobho onamandla aphezulu kunye nokuqina, okwenza ilungele uluhlu olubanzi lwezicelo. Le mibhobho isetyenziselwaityhubhu ye-weldiedItekhnoloji ngexesha lokwakhiwa, ukuqinisekisa ukuba bayamelana nezinto ezahlukeneyo zokusingqongileyo kunye noxinzelelo, ezenza ukuba balungele ngaphantsi komhlaba nangaphantsi kwamanzi.

Xa ujonga inkcazo yombhobho we-spiral seam, kubalulekile ukuba ugxile kwizinto eziphambili ezifana nobubanzi, ubukhulu becala kunye nebakala lezinto ezibonakalayo. Ububanzi bombhobho buchaza amandla ayo okuhambisa amanzi okanye igesi, ngelixa ubukhulu becala budlala indima ebalulekileyo kwingqibelelo yayo yezakhiwo kunye nokunganyange koxinzelelo. Ukongeza, ibanga lezinto ezibonakalayo limele umgangatho kunye nokuqulunqwa kwentsimbi esetyenzisiweyo kwaye kuyinto ebalulekileyo ekuqinisekiseni ububele kunye nokusebenza kombhobho kwisicelo esinikiweyo.

Ekwakhiweni kweImibhobho yamanzi aphambili, imibhobho ye-Spiral Seam ineenzuzo ezininzi. Amandla abo aphezulu e-subser kunye nokungaxhathisi i-corrosion ibenza balungele ukuthutha amanzi ngaphezulu komgama omde, ngelixa bhetyebhetye bavumela ukufakelwa ngokulula malunga nemiqobo kunye nendawo yokucela umngeni. Ukongeza, ukusetyenziswa kwemibhobho ye-Spiral Seam kwimibhobho yegesi yendalo kuqinisekisa ukuthutha okukhuselekileyo nangokufanelekileyo kwegesi yendalo, ukubonelela ngobutyebi obubalulekileyo kumacandelo ahlala, athengisayo naworhwebo.

Kwicala lesiseko, i-Spiral Seam Seam Inkcazo elawulwa yimigangatho yeshishini kunye nemigaqo yokuqinisekisa umgangatho wabo kunye nokusebenza kwabo. Umzekelo, iZiko lasePetroleum lePetroleum (API) liphuhlise imigangatho yemveliso kunye nokusetyenziswa kombhobho we-spiral-seam-seam-seam ofikelela kwiimfuno zobukhulu, amandla kunye neenkqubo zokuvavanya. Ukongeza, uluntu lwaseMelika luvavanyo kunye nezixhobo (i-ASTM) zibonelela ngokwakhiwa kwezixhobo kunye nokuchongwa kwepropathi yepropathi yokuqinisekisa ukuthembeka kwabo kunye nokuthotyelwa kwemigangatho yeshishini.

Ngesishwankathelo, i-spils ye-pierals ye-pied igxeka kwindima yayo kulwakhiwo lwezibonelelo. Nokuba isetyenziselwa amaxabiso amanzi okanyeimigca yegesi, le mibhobho inika amandla angenakuthelekiswa nanto, ukuqina kunye nokungabinamsebenzi, owenza ukuba babe nokungabinakho ukubabizelwe kwihlabathi lanamhlanje. Ngokulandela imigangatho yeShishini kunye neMigaqo, ukusetyenziswa kwemibhobho ye-Spiral Seam kuqinisekisa ukhuseleko kwiinkqubo zeziseko zophuhliso, ukutyhubela indlela yophuhliso oluzinzileyo kunye nenkqubela phambili yentlalo.

Ngaphambili: Amandla ombhobho we-wellded ophindwe kabini kwizicelo zemveliso

Okulandelayo: Izinto eziluncedo kubanda ezenziwe ngokwakhiwo
