    Ukufakwa kwepayipi le-ASTM A234 WPB ne-WPC kufaka phakathi izindololwane, ama-tee, izinciphisi

    Ukufakwa kwepayipi le-ASTM A234 WPB ne-WPC kufaka phakathi izindololwane, i-tee, izinciphisi Isithombe Esifakiwe

    Incazelo emfushane:

    Lokhu kucaciswa kuhlanganisa ukufakwa kwensimbi eyenziwe nge-carbon steel kanye ne-alloy steel yokwakhiwa okungenamthungo nokushiselwe.Lokhu kufakwa kusetshenziselwa ukufaka amapayipi okucindezelayo nasekukhiqizeni umkhumbi ocindezelayo ukuze uthole isevisi emazingeni okushisa aphakathi nendawo naphezulu.Izinto zokufakwa kuzoqukatha insimbi ebulewe, ama-forging, imigoqo, amapuleti, imikhiqizo ye-tubula engenamthungo noma ehlanganisiwe ene-filler metal.Imisebenzi yokufoja noma yokubumba ingenziwa ngokushaya ngesando, ngokucindezelwa, ukubhoboza, ukukhipha, ukucasula, ukugingqa, ukugoba, ukushisela okuhlanganisiwe, ukukhanda, noma ngokuhlanganiswa kokubili noma ngaphezulu kwale misebenzi.Inqubo yokwakha izosetshenziswa kangangokuthi ngeke iveze ukungapheleli okulimazayo kokufakwayo.Izinto zokufakwayo, ngemva kokwakhiwa ezingeni lokushisa eliphezulu, zizopholiswa zibe izinga lokushisa elingaphansi kwebanga elibalulekile ngaphansi kwezimo ezifanele ukuze kuvinjelwe ukonakala okulimazayo okubangelwa ukupholisa okushesha kakhulu, kodwa akwenzeki kube ngokushesha okukhulu kunezinga lokupholisa emoyeni onganyakazi.Ukufakwa kuzokwenziwa ukuhlolwa kwe-tension, ukuhlolwa kokuqina, nokuhlolwa kwe-hydrostatic.

    Ukukhiqiza

    Ukufakwa kwamapayipi ensimbi ekhabhoni ye-ASTM A234 kungenziwa ngamapayipi angenamthungo, amapayipi ashiselwe noma amapuleti ngokubumba imisebenzi yokucindezela, ukubhoboza, ukukhipha, ukugoba, ukushisela okuhlanganisiwe, ukukhanda, noma ngokuhlanganiswa kokubili noma ngaphezulu kwale misebenzi.Wonke ama-weld afaka ama-welds emikhiqizweni yamashubhu okwenziwa ngawo kuzokwenziwa ngokuhambisana ne-ASME Isigaba IX.Ukwelashwa kokushisa kwangemva kokushisela ku-1100 kuya ku-1250°F[595 kuya ku-675°C] nokuhlolwa kwe-radiographic kuyokwenziwa ngemva kwenqubo yokushisela.
