Uyazi ukuthi ASTM A 53? B73: UMKHOMBOTSHI WE-UNS N06022, CRA ALLOY ngenqanawe yezibopheleli ezifana ne_crevice_corrosion. Yingxenye yesiNgezi esetshenziswa ngokwemvume weAmerican Society for Testing and Materials. Kulapho akhawulezi amakhomoto okanye amakhomoto ephambili kakhulu. Kuningi loku kusetyenziswa kwisezintsha zesiNgonyama nokulula, izimo ze-buildings kunye nezinto ezinikezela amakhomoto okanye uzoba ukuhlala ngokubhidiba phakathi kwesinye isikhombelo sokugcina. Amakhomoto akhethwe ngokuphi ndawonye kwiASTM A 53 standard lokuhlola ukuba umthombo wakhe uhlinzekile ngaphandle kokuba amakhomoto akhethwe ngokuphi ndawonye kwiwelded okanye seamless products. Ngoko ke sithetha ukuthi zakhiwo zabelungu lezi zikhethe amandla nokuba zingavamile.
Kwi-ASTM A 53 amaphipha, isithelo esetshenziswa kufuneka sikhona ngokuphelele kunye nesiphumo. Yini iyini yimihla ukuthi isithelo sikhiqize ngendlela esetshenziswa yodavid. Ngokubalulekile, umphipha osedluleyo okusetshenziswa ukuhamba kwezilo noma igas ikhona ngokwesigaba esikhulu sokuhlola amagama nokuthi asikhwaleke. Amathathu angaphezu komabhedlela akhona amahlobo amacandle ethiwa ngaphandle kwalapho kufuneka amakhono amancane ahlale kuhlanganise, futhi kufuneka kuhlanganise uphawu olungulume lapho kusetyenziswa amasayensi abesekelwe ngemibuzo emishumi eziyisibili. Lolu dade lokudla kuyinto olungakufuneka, kunye nokuthi usopho lwesikhatsi sikhona ngcono ukuthi umphipha usebenze ngokukhona phakathi kwesinye.
Kunezimbini izinhlobo ezidingekileyo zemipayipi yensimbi; i-Grade A esikhona ukudla okungakho kakhulu kunye nesinye isikhala ngokwesikhatsi. U-Grade A ungenxa yokulandeleka lwe 30,000 psi (amashele angama-inchi egcweleyo). Amaphayipi we-Grade B, futhi, bayenqanawe kakhulu kunye namandla yezindaleni eliphuma ekugcineni kwe-60,000 psi. Ngenxa yokuhluphekiswa lokuhluke, amaphayipi we-Grade B akhawukwazi ukusetyenziswa kwiindlela ezinomsindo okukhulu nokusebenza kumazibuko eziyinkunzi okanye ezikade kakhulu.
Ama-payipi amahhukumezi akhetha ukwenzeka kakhulu eminyakeni encinci nendaweni zokugcina. Ngokubalulekile, ngendawo yokulilo nezilungu, ama-payipi amaphandle kuhlala kusetyenziswa ukuthi uhlalelo lwePetroleum ulenzelemise phakathi kwezindawo eziningi. Bayenza okokuqinisekisa ukuthi amamathuba ame manje njengamanje. Ama-payipi aASTM A 53 aphakathi komhlaba wakhiwo ukwenza imiswebo yebhulidingi noma njengephakati lwezindlela zokuphucula ezininzi ezindaweni eziningi. Ukudibanisa, amapayipi amahhukumezi akhetha ukwenzeka kakhulu kwiiboyila neeziphethelo esingazama umoya nokuthi amasela amelene namanye amaxhobo. Usetyenziso sabelana nokuthi bayenza ukwenza izindawo zokufundiswa kuhlu kwabantu ngokusebenzisa izindawo zokuprotekela ezingcinane lokunyelelwa kumthethosisekelo wemvume ngokushesha usuku.
Amanqayi asebenzayo kumakhaya okanye izifaktori zikhona ukuba zibhutshwe ngokulandelwa ngeASTM A 53 iindlela eziningi lokuhlola usuku lomva wasezantsi. Amanqayi angazizamsene namandla eziyi-ASTM A 53 uzoba kuhlala ukuhlaba kakhulu kwiseveni. Lokhu kungabangela amanqayi abe ngaphandle komandla, okuyingxenye yokubhukuda kwezilwandle emasimini okanye umoya wakhe, oku kungabikho isiphumo esincane kuhluke lelwandle nokuthi kungahlanganise ukusuka kwezinyawo zethu. Oku kungabangela ukuba amanqayi akhuphe indlela yokugcina ukusebenza ngamanje ngokubhalekelayo, ukuba asetshenziswa amanqayi amadala engamandla kunye nokuba azihlabe ngendlela yobunzima, kuzoba kuhlala amagcinelo amapharathisi. Ukusetshenziswa kwamanqayi esizamsene namandla eziyi-ASTM A 53, izifirma ziqinisekisa ukusafisana kwezisekelo zakhe zombuzo nokuhlola kwezinto ezinikezelwe njengelwandle, ukususa ukufa kokubiza.
Sikwazima amaprodakthi e-Amerikani/British/Australian standard H-beams astm a 53 sheet piles nokufakela izinhlelo zokubhedelela okukhulu njengokushayela nokugcina. Iziprodakthi zakho zithunyelwe ngonyaka e-Europha laseNtshonalanga kunye ne-Oceania. Zithunyelwe futhi e-South America, Southeast Asia, Afrika, kunye ne-Middle East
Siyafundisa ngezinye iindlela ezikhulu zokuthenga amagcinisi, futhi wonke amanqaku akhona azibuyiswe ngaphambi kokuthumela, uquyeka kusigxekelwa. Imanqaku emfanele yonke ilizwi lokuncane lama-pipes (ERW/SSAW/LSAW/ galvanized/astm a 53/seamless pipe/stainless steel pipe), amaprora (isithombe saseMerika, isithombe saseBhritane, isithombe saseOstraliya H-beam steel), amabara, Angle steel, flat steel, steel sheet piles, amabhalwa angasinye sokugcina namakhozi okanye amacilungu, strip steel, scaffolding, steel wire, amathswa, netshwe.
Kwethu kwisebentiso sawo sikukhulu nokuthi siyiqhawekazi le-17 esikhehleni samalayini wemali nokuthenga amagcinisi, singakwazanga ukufakwa kakhulu kuma astm a 53 kunye nezinkomo. Ngakwesoku, sifuna umphilo omncane wezinsiza zakwesayensi, usizo olungaphambili kunye nesixhobo. Ukuthi uzame kakhulu kuhluke ukuthi imali ikhuphe!
Umphakathi wethu wesikabi esidingi kakhulu kwi-foreign trade astm a 53 usebenzisa imigomo yezilungiselelo ezikhona kanye nokuthola amabhayisithi omncane ngenqanawe ngokupheleleyo ngesinye sikhoho sokusebenza kakhulu Sihlala noma zonke izikhondo zomzekelo zokuthola lokuhlola Izinhlobo zethu zikhona ekusenzeleni ukuthi zibhekene namandla okulandelayo yokusebenza ukwamukela izindlela ezifaneleyo Zikhona noma zonke izikhondo zomzekelo zokuthola lokuhlola ngalanga lasehlanu ukuze uzame ukufinyelela ukuzama ukwenza izinhlamvu noma ukufinyelela izicwangciso Siyiqinisekisi elikhulu lokuthi sizohlala ngokubanjwa
