Iipayipi zentsimbi zihlulwe njani ngokwezinto ezisetyenzisiweyo?
Iipayipi zentsimbi zinokwahlulwa zibe ziipayipi zesinyithi ezingeyo-ferrous kunye neepayipi ze-alloy, iipayipi zesinyithi zekhabhoni eziqhelekileyo, njl. ngokwezixhobo zazo. Iipayipi zentsimbi ezimeleyo ziquka iipayipi zesinyithi ze-alloy ezingenamthungo.I-ASTM A335 P5, umbhobho wentsimbi yekhabhoniI-ASME A106 GRB
Iipayipi zentsimbi zihlulwe njani ngokweemilo zazo ezinqamlezileyo?
Imibhobho yentsimbi inokwahlulwa ibe yimibhobho engqukuva kunye nemibhobho enemilo ekhethekileyo ngokwemilo yayo enqamlezileyo.
Iipayipi zentsimbi zihlelwa njani ngokwemeko yesiphelo sepayipi?
Impendulo: Ityhubhu engenanto kunye netyhubhu enemisonto (ityhubhu enemisonto)
Iipayipi zentsimbi zihlulwe njani ngokobubanzi nodonga?
①Ityhubhu enodonga oluqinileyo kakhulu (D/S＜10) ②Ityhubhu enodonga oluqinileyo (D/S=10~20) ③Ityhubhu enodonga olubhityileyo (D/S=20~40) ④Ityhubhu enodonga olubhityileyo kakhulu
(D/S ＞40)
Umlinganiselo wobubanzi nodonga ubonisa ubunzima bokuveliswa kwemveliso yokuqengqeleka kwemibhobho yentsimbi.
Ziphawulwa njani iintlobo kunye neenkcukacha zeepayipi zentsimbi ezingenamthungo?
Iinkcukacha zeepayipi zentsimbi ezingenamthungo zibonakaliswa bubungakanani obuqhelekileyo bobubanzi bangaphandle, ubukhulu bodonga kunye nobude, njenge-76mm×4mm×5000mm engenamthungo
Umbhobho wentsimbi ubhekisa kumbhobho wentsimbi onobubanzi bangaphandle obuyi-76mm, ubukhulu bodonga obuyi-4mm, kunye nobude obuyi-5000mm. Kodwa ngokubanzi, kusetyenziswa ububanzi bangaphandle kunye nobukhulu bodonga kuphela.
