ImiGangatho yeSizwe kunye neMigangatho yaseMelika yeMibhobho yentsimbi kunye nezicelo zabo

Kwimizi-mveliso yanamhlanje kunye nemimandla yokwakha,Umbhobho wentsimbi yeCarbonzisetyenziswa ngokubanzi ngenxa yokuqina kwazo okuphezulu, ukuqina okuhle kunye neenkcukacha ezahlukeneyo. Imigangatho yesizwe yaseTshayina (gb/t) kunye nemigangatho yaseMelika (astm) ziinkqubo ezisetyenziswa ngokuqhelekileyo. Ukuqonda amabakala kunye nomahluko wabo kubaluleke kakhulu ekukhethweni kweUNkszn Steel Pipe. ​

Phakathi kwamabakala aqhelekileyo emibhobho yentsimbi yesizwe, i-carbon structural steels iquka i-q195 - q275. Njengokuba,Q235 uMbhobho weNtsimbiinamandla esivuno se-235mpa kwaye isetyenziswa kulwakhiwo jikelele kunye nokuveliswa koomatshini. I-alloy ephantsi yamandla aphezulu ensimbi yesakhiwo i-q345 isetyenziswa ngokubanzi kwaye ifanelekile kwizakhiwo ezinkulu ezifana neebhulorho. Ngokwemigangatho yaseMelika, i-carbon structural steel a36 isetyenziswa kwiiprojekthi zokwakha. I-alloy ephantsi yamandla aphezulu ensimbi yesakhiwo i-a572 gr.50 isetyenziswa kwizakhiwo ezinkulu.

 

Ngokubhekiselele kwiipropathi zoomatshini, kukwakho umahluko kwiimfuno zezalathisi ezinje ngokuqina kwesivuno, amandla okuqina, kunye nokwandiswa kwemveliso.CiarbonSithiPipephakathi komgangatho wesizwe kunye nomgangatho waseMelika. Ngokuqhelekileyo, kuhlobo olufanayo lwensimbi, umgangatho waseMelika unokuba neemfuneko ezingqongqo ngokubhekiselele kwizibonakaliso zamandla, ngelixa umgangatho waseTshayina unokuba nemimiselo ecacileyo malunga nezibonakaliso zokuqina. Ngokumalunga nokubunjwa kweekhemikhali, uluhlu lomxholo wezinto ezahlukeneyo ze-alloying kunye nezithintelo kwizinto zokungcola kwezi zimbini zikwahluke. Umzekelo, umgangatho waseMelika ubhetyebhetye ngakumbi ekongezweni nasekulawuleni izinto ezithile zokudibanisa ukuze uhlangabezane neemfuno ezikhethekileyo zeeprojekthi ezahlukeneyo. Umgangatho wesizwe uhlawula ingqalelo ngakumbi kwindalo yonke kunye nokuzinza kwentsimbi.

 

Kukwakho iyantlukwano phakathi kwemigangatho yesizwe kunye neemfuneko zonyamezelo lwedimensional forCiarbonSithiPipe. Umgangatho wesizwe ubonelela ngemimiselo eneenkcukacha malunga nokunyamezelana okulinganayo okufana nobukhulu bangaphandle kunye nobukhulu bodonga lwemibhobho yentsimbi, kwaye wenze amabakala ahambelanayo okunyamezelana ngokweendidi ezahlukeneyo zemibhobho yentsimbi.Q235SithiPipekunye neemeko zesicelo. Umgangatho waseMelika unemigaqo ethambileyo ngakumbi malunga nokunyamezelwa komgangatho, kodwa iimfuno zayo zokuchaneka komgangatho ziya kulungelelaniswa ngokwezicelo ezahlukeneyo zoshishino kunye neemfuno zabathengi.

 

IkhabhoniSithiPipeube noluhlu olubanzi lwezicelo. Kwintsimi yolwakhiwo, yinto ephambili kwi-scaffolding kunye nezakhiwo zetsimbi, kwaye isetyenziselwa ukubonelela ngamanzi kunye neenkqubo zokuhambisa amanzi. Kwishishini lepetrochemical, imibhobho ye-oyile yequla kunye ne-corrosion-resistant stainlessimibhobho yentsimbingokulandelelanayo ukuhlangabezana neemfuno zotsalo kunye nokuthuthwa kosasazo lwekhemikhali. Kwimveliso yoomatshini, ukusuka kwiimoto ukuya koomatshini bokwakha, Ikhabhoni SithiPipeszisetyenziselwa ukunciphisa ubunzima kunye nokuqinisekisa ukuhanjiswa kwamandla. Kwicandelo lamandla, ubushushu obuphezulu be-steam buthuthwa ngemibhobho yensimbi yebhoyili, igesi yendalo ithuthwa ngemibhobho yomgama omde, kwaye iinqaba zamandla omoya nazo zixhomekeke kwimibhobho yentsimbi. ​

 

Ukuqukumbela, zombini umgangatho wesizwe kunye nomgangatho waseMelika weQ235SithiPipe

Baneempawu zabo kwaye badlale indima ebalulekileyo kwiinkalo ezininzi. Kwisicelo esisebenzayo, kuyimfuneko ukukhetha ngokufanelekileyo umgangatho ohambelanayoMS SithiPipeibakala elisekelwe kwiimfuno zeprojekthi kunye nokusingqongileyo ukuqinisekisa umgangatho nokhuseleko lweprojekthi.

 

Qhagamshelana nathi ukuze ufunde ngakumbi malunga nolwazi lweshishini.
