Umbhobho wentsimbi odityanisiweyo, owaziwa ngokuba ngumbhobho odityanisiweyo, ngumbhobho wentsimbi owenziwe ngepleyiti yentsimbi okanye umtya wentsimbi emva kokudityaniswa kunye nokudityaniswa.Umbhobho wensimbi odityanisiweyo unenkqubo elula yokuvelisa, ukusebenza kakuhle kwemveliso, iintlobo ezininzi kunye neenkcukacha, kunye nezixhobo ezincinci, kodwa amandla ayo aqhelekileyo angaphantsi kunemibhobho yensimbi engenamthungo.Ukusukela ngeminyaka yoo-1930s, kunye nophuhliso olukhawulezayo lomgangatho ophezulu wentsimbi eqhubekayo yemveliso eqengqelekayo kunye nokuqhubela phambili kwe-welding kunye nokuhlola itekhnoloji, umgangatho we-welds uphuculwe ngokuqhubekayo, iintlobo kunye neenkcukacha zemibhobho yentsimbi edityanisiweyo ziye zanda, kwaye ngakumbi kwaye amasimi ngaphezulu athathe indawo yentsimbi non-ayoni.Umbhobho wentsimbi yomthungo.Imibhobho yentsimbi edityanisiweyo yohlulwe yaba yimibhobho edityanisiweyo ethe tye kunye nemibhobho edityanisiweyo ejijekileyo ngokwendlela yeentsimbi.
Inkqubo yokuvelisa umbhobho odityanisiweyo othe tye ilula, ukusebenza kakuhle kwemveliso kuphezulu, ixabiso liphantsi, kwaye uphuhliso lukhawuleza.Amandla ombhobho odityanisiweyo we-spiral i-spiral seam angaphezulu ngokubanzi kunombhobho odityanisiweyo othe tye, kwaye umbhobho odityanisiweyo onobubanzi obukhulu unokuveliswa ngebillet encinci, kwaye umbhobho odityanisiweyo onobubanzi bombhobho ohlukeneyo nawo unokuveliswa nge billet yobubanzi obufanayo.Nangona kunjalo, xa kuthelekiswa nobude obufanayo bombhobho wokuthunga othe tye, ubude be-weld bunyuswe ngama-30 ~ 100%, kwaye isantya sokuvelisa siphantsi.Ke ngoko, uninzi lwemibhobho edityanisiweyo enedamitha ezincinci zisebenzisa i-welding ye-seam ethe tye, kwaye uninzi lwemibhobho edityanisiweyo enobubanzi obukhulu isebenzisa i-spiral welding.
1. Imibhobho yentsimbi edityanisiweyo yothutho lwe-low-pressure fluid ikwabizwa ngokuba yimibhobho edityanisiweyo ngokubanzi, eyaziwa ngokuba yimibhobho emnyama.Ngumbhobho wentsimbi odityanisiweyo wokuhambisa ulwelo oluphantsi loxinzelelo jikelele olufana namanzi, igesi, umoya, i-oyile kunye nokufudumeza umphunga kunye nezinye iinjongo.Ubunzima bodonga lombhobho wensimbi buhlulwe kumbhobho wensimbi oqhelekileyo kunye nombhobho wensimbi oqiniweyo;ifom yokuphela kombhobho ihlulwe ibe ngumbhobho wensimbi ongenazintambo (umbhobho ogudileyo) kunye nombhobho wensimbi odibeneyo.Ukucaciswa kombhobho wensimbi kubonakaliswa yi-diameter ye-nominal (mm), eyi-approximation ye-diameter yangaphakathi.Kuyinto yesiko ukuvakalisa ngee-intshi, ezifana ne-11/2 njalo njalo.Ukongeza ekusetyenzisweni ngokuthe ngqo ukuthutha ulwelo, imibhobho yentsimbi edityanisiweyo yokuthutha ulwelo olunoxinzelelo oluphantsi nayo isetyenziswa ngokubanzi njengemibhobho yoqobo yemibhobho yentsimbi edityanisiweyo yokuhambisa ulwelo olunoxinzelelo oluphantsi.
2. Umbhobho wentsimbi odityanisiweyo odityanisiweyo wokuthuthwa kwamanzi anoxinzelelo oluphantsi ukwabizwa ngokuba ngumbhobho wentsimbi owenziwe ngombane, owaziwa ngokuba ngumbhobho omhlophe.Ngumbhobho wentsimbi odiphulwe ngokushushu-diphu (iziko elidityanisiweyo okanye elidityaniswe ngombane) esetyenziselwa ukuhambisa amanzi, igesi, ioyile yomoya, ukufudumeza umphunga, amanzi ashushu kunye nolunye ulwelo oluphantsi loxinzelelo jikelele okanye ezinye iinjongo.Ubukhulu bodonga lombhobho wentsimbi buhlulwe kumbhobho oqhelekileyo wentsimbi kunye nombhobho wensimbi oqinileyo;ifom yesiphelo sombhobho yahlulwe ibe ngumbhobho wentsimbi engafakwanga ngemisonto kunye nombhobho wentsimbi oxutywe ngentambo.Ukucaciswa kombhobho wensimbi kubonakaliswa yi-diameter ye-nominal (mm), eyi-approximation ye-diameter yangaphakathi.Kuyinto yesiko ukuvakalisa ngee-intshi, ezifana ne-11/2 njalo njalo.
3. I-carbon steel wire casing eqhelekileyo ngumbhobho wensimbi osetyenziselwa ukukhusela iingcingo kwiiprojekthi zokufakelwa kombane ezifana nezakhiwo zoshishino kunye nezakhiwo zoluntu, ukufakwa koomatshini kunye nezixhobo.
4. Umthungo othe ngqo wombane odibeneyo wentsimbi ngumbhobho wentsimbi kunye ne-weld seam ehambelana nolwalathiso olude lombhobho wensimbi.Ngokwesiqhelo yahlulwe kumbhobho wentsimbi wemetric odityanisiweyo, umbhobho wombane odityanisiweyo obhityileyo, umbhobho weoyile wokupholisa isiguquli njalo njalo.
5. I-Spiral seam entywiliselweyo i-arc welded steel pipe yokuthutha ulwelo olucinezelekileyo ngumbhobho wentsimbi ojikelezayo osetyenziselwa ukuthutha ulwelo olucinezelekileyo, engumtya wentsimbi oshushu oqengqelekayo njengetyhubhu engenanto, edla ngokuyilwa yi-spiral efudumeleyo, kwaye idityaniswe ngokuphindwe kabini- ukuwelda kwe-arc emacaleni.Umbhobho wentsimbi unamandla okunyamezela uxinzelelo kunye nokusebenza kakuhle kwe-welding.Emva kohlolo olungqongqo lwesayensi kunye novavanyo, kukhuselekile kwaye kuthembekile ukuyisebenzisa.Ububanzi bombhobho wensimbi bukhulu, ukusebenza kakuhle kokuthutha kuphezulu, kwaye utyalo-mali ekubekeni imibhobho lunokugcinwa.Isetyenziswa kakhulu kwimibhobho yokuthutha ioli kunye negesi yendalo.
6. Umbhobho wentsimbi odityanisiweyo we-spiral we-frequency high-frequency welded ye-pressurized fluid transportation yenziwe nge-coil yentsimbi eshushu eqengqelekayo njengetyhubhu engenanto, edla ngokuyilwa yi-spiral efudumeleyo, kwaye idityaniswe yi-high-frequency lap welding.Umbhobho wentsimbi odityanisiweyo.Umbhobho wentsimbi unamandla okuthwala uxinzelelo kunye neplastiki efanelekileyo, ekulungele ukuwelda kunye nokucutshungulwa.Emva kokuhlolwa okungqongqo kunye nesayensi kunye novavanyo, kukhuselekile kwaye kuthembekile ukuyisebenzisa.Umbhobho wensimbi unobubanzi obukhulu kunye nokusebenza kakuhle kokuthutha, kwaye unokugcina utyalo-mali ekubekeni imibhobho.Ikakhulu isetyenziselwa ukubeka imibhobho yokuthutha ioli, igesi yendalo, njl.
7. Ngokubanzi, i-spiral seam entywilayo i-arc welded steel pipe yokuthutha ulwelo oluphantsi-loxinzelelo lwenziwe nge-coil yentsimbi eshushu-isolwe njengetyhubhu engenanto, kwaye ihlala isenziwa kwi-spiral efudumeleyo.Yenziwe ngemibhobho yentsimbi edityanisiweyo ye-arc enamacala amabini ngokuzenzekelayo okanye ukuwelda kwicala elinye lamanzi, igesi kunye nomoya.
8. I-spiral seam high-frequency welded steel pipe yokuthutha ulwelo oluphantsi koxinzelelo oluphantsi lwenziwe ngentsimbi eshushu eqengqelekayo njengetyhubhu engenanto, edla ngokuyilwa yi-spiral eshushu, kwaye idityaniswe yi-high-frequency lap welding.Isetyenziselwa ukuthutha ulwelo oluphantsi koxinzelelo jikelele..
9. Imibhobho yentsimbi ene-Spiral-welded yeemfumba yenziwe ngeentsimbi ezishushu eziqengqelekayo njengeetyhubhu ezingenanto, ezihlala zisenziwa ngama-spirals afudumeleyo, kwaye zenziwe nge-arc ye-arc enecala eliphindwe kabini okanye i-high-frequency welding.Zisetyenziselwa iimfumba zesiseko ezifana nezakhiwo zokwakha, ii-wharfs, kunye neebhulorho.Sebenzisa imibhobho yentsimbi.
