Ukuqonda umbhobho we-ASTM A252
Ehlabathini lokwakha kunye nobunjineli boluntu, ukukhethwa kwezinto eziphathekayo kubalulekile ukuqinisekisa ukuthembeka kunye nokuphila ixesha elide kwesakhiwo. Enye into ehlonitshwa kakhulu kwishishini ngumbhobho we-ASTM A252. Le ngcaciso ibaluleke kakhulu kwabo basebenza ngeeprojekthi zokufunxa, njengoko igquma iimfumba zentsimbi yombhobho wentsimbi.
Yintoni iI-ASTM A252?
I-ASTM A252 yinkcazo esemgangathweni echaza iimfuno zemibhobho yentsimbi edityanisiweyo kunye nengenamthungo. Le mibhobho iyilelwe ukuba isetyenziswe njengamalungu asisigxina athwele umthwalo okanye njengamaqokobhe eemfumba ezifakwe kwindawo yekhonkrithi. Le ngcaciso ibalulekile ukuqinisekisa ukuba imibhobho inokumelana noxinzelelo kunye nemithwalo enokuthi ihlangabezane nayo kwiintlobo ezahlukeneyo zezicelo, ngakumbi ubunjineli besiseko.
IUmbhobho we-ASTM A252iinkcukacha zohlulwe ngokwamabakala amathathu, ngalinye lineemfuno ezahlukeneyo zamandla esivuno. Amandla aphezulu esivuno anokufikelela kwi-450MPa, okwenza ukuba ilungele izakhiwo ezinzima ezifana neeBridges kunye nezakhiwo eziphakamileyo.
Uyilo oluhlala ixesha elide: Ingasetyenziswa njengenxalenye esisigxina yokuthwala umthwalo okanye iqokobhe lengqumba yekhonkrithi, ukumelana nemekobume enomhlwa engaphantsi komhlaba.
Ukuguquguquka okuguquguqukayo: Uluhlu lweDiameter Φ219mm-Φ3500mm, ubukhulu bodonga 6-25.4mm, bulungele iimeko zejoloji ezinzima
Amandla ethu angundoqo
Ngobuchule obuphambili bokuvelisa kwishishini, umthamo wonyaka wemveliso ongaphezulu kweetoni ezingama-500,000, inomnye wemigca embalwa yemveliso yasekhaya yobubanzi obukhulu bemibhobho yentsimbi ejikelezayo Φ3500mm.
Inkqubo ye-arc welding (SAW) ephantsi kwamanzi iyamkelwa, kwaye umgangatho we-weld uqinisekiswa ngovavanyo olungonakalisi njenge-X-rays kunye namaza e-ultrasonic.
Inkqubo epheleleyo yokulawula umgangatho
Ukusuka kwizinto eziluhlaza ukuya kwiimveliso ezigqityiweyo, iUmbhobho we-Astm A252umgangatho uphunyezwe ngokungqongqo
Ixhotyiswe nge-epoxy anti-corrosion / 3PE anti-corrosion treatment, eyandisa ubomi benkonzo kwiindawo zaseLwandle ngaphezu kwe-30%
Inethiwekhi yenkonzo yehlabathi
Iimveliso zithunyelwa kumazwe angaphezu kwama-30 kuquka iYurophu, iMelika, iSoutheast Asia kunye noMbindi Mpuma
Ukuxhasa imveliso eyenziwe ngokwezifiso kunye nokubonelela ngeenkonzo zokumisa enye ukusuka ekukhetheni ukuya kwisikhokelo sokwakha
Lilonke, imibhobho ye-ASTM A252 iyinxalenye ebalulekileyo kulwakhiwo kunye nemimandla yobunjineli boluntu, ibonelela ngamandla ayimfuneko kunye nokuqina kwezicelo ezahlukeneyo. I-Cangzhou Spiral Steel Pipe Group Co., Ltd. ngumenzi ohamba phambili wolu hlobo lombhobho, enikezela uluhlu olubanzi lobukhulu kunye nobukhulu bodonga ukuhlangabezana neemfuno ezithile zabathengi bethu. Nokuba usebenza kwiiprojekthi zokufumbathisa okanye ezinye iiprojekthi zokwakha, ukuqonda ukubaluleka kwemibhobho ye-ASTM A252 kunye nokusebenza nomenzi othembekileyo kuya kubaluleka kwimpumelelo yeprojekthi yakho.
