Ipayipi Lensimbi le-ASTM A252 Lebanga 1/2/3 LSAW | Ipayipi Lensimbi Eliyisisekelo Elikhulu Elinobubanzi Obukhulu be-OD 508-1422mm Isithombe Esivelele

Incazelo emfushane:

Amapayipi ensimbi e-LSAW, ahambisana nezindinganiso ze-ASTM A252, ayizinqwaba zamapayipi ensimbi aqinile, anobubanzi obukhulu afanelekela ubunjiniyela besisekelo, ukwakhiwa kwamabhuloho, ubunjiniyela basolwandle, kanye namaphrojekthi engqalasizinda anzima. Amapayipi ensimbi e-LSAW anikeza ukuma okuhle kwesakhiwo, ukushibilika okuhle, kanye nomthamo wokuthwala umthwalo, okwenza afanelekele ukusetshenziswa kwesisekelo esijulile. Ububanzi bangaphandle busukela ku-508 kuya ku-1422 mm. Lawa mapayipi ensimbi e-LSAW ahambisana ne-ASTM aklanywe ngokwezincazelo zamanje zemboni kanye nezindinganiso, ukuqinisekisa amandla aphezulu, ukujiya kodonga okufanayo, kanye nokuqina okuphezulu ngisho nasezindaweni ezinomhlabathi onzima kanye namanzi anosawoti.

Lawa mapayipi ensimbi e-LSAW afanelekela izisekelo zamabhuloho, izindawo zokugcina amachweba, amapulatifomu asogwini lolwandle, izisekelo zezakhiwo eziphakeme, kanye nengqalasizinda yezimboni. Ukubambisana nezinkontileka eziningi ze-EPC ezinolwazi kanye nezixazululo zokwakha zomhlaba wonke kuqinisekisa impilo yazo yesevisi ende, ukumelana nokugqwala okuphezulu (ngezinto zokugqoka ezingakhethwa), kanye nokulula kokufakwa.

Isicelo Esiyinhloko

1. Ukwakha Isisekelo (Izinhlelo Zesisekelo Esijulile)

Isetshenziswa njengezinqwaba zesisekelo ezijulile zezakhiwo eziphakeme, amafektri ezimboni, izindawo zokugcina impahla, izakhiwo zezentengiselwano, kanye nezakhiwo zokuhlala. Lezi zinqwaba zamapayipi ensimbi zinikeza amandla aqinile okuthwala umthwalo oqondile futhi ziqinisekisa ukuzinza kwesakhiwo isikhathi eside ezimweni ezibuthakathaka noma ezithambile zenhlabathi.

2. Ubunjiniyela beBridge Foundation

Kuhle kakhulu kumabhuloho omgwaqo omkhulu, amabhuloho esitimela, imigwaqo ephakeme yasemadolobheni, kanye nezakhiwo ezidlula ngaphezulu.Izinqwaba zensimbi ze-ASTM A252 LSAW / EFWzisetshenziswa kabanzi ezisekelweni zamabhuloho okuwela imifula, ukuwela ichibi, kanye nokuwela ulwandle, zinikeza ukumelana okuhle kakhulu nemithwalo enamandla kanye nokuhamba kwenhlabathi.

3. Ukwakhiwa Kwechweba Nemikhumbi

Isetshenziswa ezikhumulweni zemikhumbi, emagcekeni ezitsha, emagcekeni emikhumbi, emapulatifomu edokhi, nasezindaweni zokulayisha ezisogwini. Lezi zinqwaba zamapayipi ensimbi zenzelwe ukusekela ama-crane asindayo, izinhlelo zokuphatha imithwalo, kanye nengqalasizinda enkulu yasolwandle enokuqina okuphezulu ezindaweni ezingcolisayo zasogwini.

4. Amandla Omoya Angaphandle Kwaselwandle kanye Nobunjiniyela Basemanzini

Kusetshenziswa kabanzi ezisekelweni ze-wind turbine zasogwini, amapulatifomu asogwini, amapayipi olwandle, izindonga zasolwandle, kanye nezakhiwo zokuvikela ugu.Ipayipi lensimbi le-LSAWAma-pile anikeza ukumelana okuhle kakhulu nokushaywa amagagasi, amandla olwandle, kanye nokugqwala kwamanzi olwandle, okwenza afanelekele izindawo ezinzima zasogwini.

5. Amaphrojekthi Obunjiniyela Bokwakha Amakhulu

Isetshenziswa emadamini, eziteshini zesitimela ezingaphansi komhlaba, emihubheni, ezakhiweni zokugcina izinto, kanye namaphrojekthi amakhulu engqalasizinda adinga ukwesekwa okujulile kwesisekelo. Lawa maqoqo ayakwazi ukuthwala imithwalo yemishini yezimboni esindayo kanye nezimo zokucindezeleka kwesakhiwo eziyinkimbinkimbi.

3) Kuhlolwa izinhlangano ezigunyaziwe njenge-CCIC, i-SGS, i-BV, ne-TUV, kanye nokupakishwa okujwayelekile okufanele ulwandle

Ukupakisha Nokulethwa

1 Ukupakisha:Ibhande lensimbi ukuze kube lula ukuphatha. Amabhulokhi okhuni noma i-dunnage kubekwa phakathi kwezinqwaba ukuze kugwenywe ukushintsha kwezitho ngesikhathi sokuthuthwa. Ukwelashwa kwendawo (ongakukhetha): Ukupenda okumnyama, uwoyela wokuvimbela ukugqwala, ifilimu yepulasitiki. Izinqwaba ze-galvanized ezicwiliswa ngokushisa zingase zimbozwe ifilimu yokuvikela yesikhashana ukuze kugwenywe ukuklwebheka ebusweni. Kunganikezwa ukupakishwa okwenziwe ngokwezifiso.

2 Ukulethwa:Ubude besitoko obujwayelekile: 6m, 12m. Itholakala ngobude obujwayelekile. Iza ne-Sea Rail kanye ne-Road Esebenzayo. Ifanelekela ezokuthutha olwandle, isitimela noma umgwaqo. Isikhathi sokulethwa sivame ukuba yizinsuku eziyi-15-30 ngemuva kokuthola inkokhelo, kuye ngobuningi kanye nemininingwane. Ifanelekela ukuthunyelwa kwamanye amazwe emhlabeni jikelele, kanye nedokhumenti ephelele (isitifiketi sokuhlola, uhlu lokupakisha, i-bill of lading).

3 Izinyathelo Zokuqapha Zokusingatha:Ungasebenzisi izihlilingi noma izingwegwe ezingenamaphedi ukuze zisebenze ngqo ebusweni bepayipi ukuze ugweme ukuthi ipayipi lingaguquki. Gcina endaweni epholile, eyomile futhi enomoya omuhle, gwema ukugqwala ngaphambi kokufaka. Ukuthunyelwa okukhulu kakhulu nokwesisindo esikhulu sicela uhambisane nemithetho yokuthumela yendawo.

Imibuzo Evame Ukubuzwa

1. Ukusetshenziswa kwamapayipi ensimbi e-ASTM A252 Grade 3?

Amapayipi ensimbi e-ASTM A252 Grade 3 LSAW asetshenziswa kakhulu ekufakweni kwesisekelo esijulile emisebenzini yokwakha, njengezakhiwo, amabhuloho, amachweba, ulwandle nokunye.

2. Ibanga loku-1, iBanga lesi-2 kanye neBanga lesi-3 zihluke kanjani?

Inikeza amandla nokuqina okuhle kakhulu kwamabanga ama-3, ngakho-ke ilungele izisekelo ezisindayo, kanye nobunjiniyela basolwandle.

3. KuyiniIshubhu yensimbi ye-LSAW?

Iguqulwe ngokolwazi lochwepheshe lwezinsimbi, ipayipi le-LSAW liwumkhiqizo wepayipi okhiqizwa ngamapuleti ensimbi okwakha kanye nokushisela okude, okubizwa nangokuthi “ipayipi lensimbi elishisiwe eliyindilinga”.

4. Yiziphi izilinganiso nobukhulu obutholakalayo?

Ububanzi obutholakalayo obu-2 busukela ku-OD 406 mm kuya ku-2500 mm kanti ubukhulu bodonga busukela ku-6 mm kuya ku-60 mm obusebenza emisebenzini yokwakha isisekelo esindayo kanye neyasolwandle.

5. Ingabe ingasetshenziswa kumaphrojekthi asemanzini nasogwini lolwandle?

Yebo. Ivame ukusetshenziswa emandleni omoya asogwini lolwandle, ezindongeni zasolwandle, emachwebeni, nasezinkundleni zasolwandle, phakathi kwezinye. Inezimbozo ezifaka phakathi i-epoxy, i-3PE, nodaka lwesimende lokulwa nokugqwala.
