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