Imigangatho yeSizwe kunye neMigangatho yaseMelika yeeMbhobho zeNsimbi kunye nezicelo zazo

Kwimimandla yanamhlanje yemizi-mveliso neyokwakha,Umbhobho wentsimbi yekhabhonizisetyenziswa kakhulu ngenxa yokuba zinamandla aphezulu, ziqinile kwaye zineenkcukacha ezahlukeneyo. Imigangatho yesizwe saseTshayina (gb/t) kunye nemigangatho yaseMelika (astm) ziinkqubo ezisetyenziswa rhoqo. Ukuqonda amabakala kunye nomahluko wazo kubaluleke kakhulu ekukhetheniUmbhobho weNtsimbi kaNksz..

Phakathi kweendidi eziqhelekileyo zeepayipi zentsimbi ezisemgangathweni zesizwe, iintsimbi zesakhiwo sekhabhoni ziquka i-q195 - q275. Umzekelo,QUmbhobho wentsimbi we-235inamandla okuvelisa angama-235mpa kwaye isetyenziswa ekwakheni ngokubanzi nakwimveliso yoomatshini. Intsimbi yesakhiwo eyomeleleyo ene-alloy ephantsi q345 isetyenziswa kakhulu kwaye ifanelekile kwizakhiwo ezinkulu ezifana neebhulorho. Ngokwemigangatho yaseMelika, intsimbi yesakhiwo sekhabhoni i-a36 isetyenziswa kwiiprojekthi zokwakha. Intsimbi yesakhiwo eyomeleleyo ene-alloy ephantsi i-a572 gr.50 isetyenziswa kwizakhiwo ezinkulu.

 

Ngokweempawu zoomatshini, kukwakho umahluko kwiimfuno zezalathisi ezinje ngamandla okuvelisa, amandla okutsalwa, kunye nokwandiswaCi-arbonSi-teelPipephakathi komgangatho wesizwe kunye nomgangatho waseMelika. Ngokubanzi, kuhlobo olufanayo lwentsimbi, umgangatho waseMelika unokuba neemfuno ezingqongqo ngokwezalathisi zamandla, ngelixa umgangatho waseTshayina unokuba nemigaqo eneenkcukacha ngakumbi ngokwezalathisi zokuqina. Ngokuphathelele ukwakheka kweekhemikhali, uluhlu lomxholo wezinto ezahlukeneyo zokudibanisa kunye nemiqathango kwizinto ezingacocekanga zezi zinto zimbini nazo zahlukile. Umzekelo, umgangatho waseMelika uguquguqukayo ngakumbi ekongezweni nasekulawulweni kwezinto ezithile zokudibanisa ukuze kuhlangatyezwane neemfuno ezikhethekileyo zeeprojekthi ezahlukeneyo. Umgangatho wesizwe unika ingqalelo ngakumbi kwi-universality kunye nokuzinza kwentsimbi.

 

Kukwakho umahluko phakathi kwemigangatho yesizwe kunye neemfuno zokunyamezelana okulinganayoCi-arbonSi-teelPipeUmgangatho wesizwe ubonelela ngemigaqo eneenkcukacha malunga nokunyamezelana okufana nobubanzi bangaphandle kunye nobukhulu bodonga lweepayipi zentsimbi, kwaye uqulunqa amanqanaba okunyamezelana ahambelanayo ngokweentlobo ezahlukeneyoQ235Si-teelPipekunye neemeko zokusetyenziswa. Umgangatho waseMelika unemigaqo elula ngakumbi malunga nokunyamezelana kobukhulu, kodwa iimfuno zawo zokuchaneka kobukhulu ziya kulungiswa ngokwezicelo ezahlukeneyo zoshishino kunye neemfuno zabathengi.

 

IkhabhoniSi-teelPipeineendlela ezahlukeneyo zokusetyenziswa. Kwicandelo lokwakha, sisixhobo esibalulekileyo kwizakhiwo ze-scaffolding kunye nezentsimbi, kwaye ikwasetyenziswa kwiinkqubo zokubonelela ngamanzi kunye nokuhambisa amanzi. Kwishishini le-petrochemical, imibhobho yemithombo yeoyile kunye ne-stainless stainless enganyangekiyo ngumhlwaimibhobho yentsimbingokulandelelanayo ziyahlangabezana neemfuno zokukhupha kunye nokuthuthwa kwezinto zamakhemikhali. Kwimveliso yoomatshini, ukusuka kwiimoto ukuya koomatshini bokwakha, Ikhabhoni Si-teelPiipezisetyenziselwa ukunciphisa ubunzima nokuqinisekisa ukuhanjiswa kwamandla. Kwicandelo lamandla, umphunga oshushu kakhulu uthuthwa ngemibhobho yentsimbi yebhoyila, igesi yendalo ithuthwa ngemibhobho ekude, kwaye iinqaba zamandla omoya nazo zixhomekeke kwimibhobho yentsimbi.

 

Ukuqukumbela, zombini umgangatho wesizwe kunye nomgangatho waseMelikaQ235Si-teelPipe

Baneempawu zabo kwaye badlala indima ebalulekileyo kwiindawo ezininzi. Kwindlela yokusebenza, kuyimfuneko ukukhetha ngokufanelekileyo umgangatho ohambelanayoMS Si-teelPipeinqanaba elisekelwe kwiimfuno zeprojekthi kunye nokusingqongileyo ukuqinisekisa umgangatho kunye nokhuseleko lweprojekthi.
