Tekanyetso ea ASME B16.9 ke tekanyetso e fanoeng ke American Society of Mechanical Engineers (ASME) e nang le sehlooho se reng “Factory-Made Wrought SteelLisebelisoa tsa Welding Butt“. Tekanyetso ena e totobatsa litlhoko tsa litekanyo, mekhoa ea tlhahiso, lisebelisoa, le tlhahlobo ea lisebelisoa tsa tšepe tse cheselitsoeng le tse se nang seam bakeng sa ho hokahanya le ho fetola tsela le boholo baliphaephetsamaisong ea liphaephe.
E boetse e hlahisa litaba tsa mantlha le litšobotsi tsa maemo a ASME B16.9:
Sebaka sa ts'ebeliso:
Tekanyetso ea ASME B16.9 e sebetsa ho lipeipi tse tloaelehileng tsa tšepe tse cheselitsoeng le tse se nang seam, ho kenyeletsoa matsoele, li-reducers, liphaephe tse lekanang tsa bophara, li-flange, li-tee, lifapano, joalo-joalo, bakeng sa ho hokahanya le ho fetola tsela le boholo ba liphaephe.
Tekanyetso e totobatsa boholo ba bophara ba lisebelisoa tsena, ho tloha ho 1/2 inch (DN15) ho isa ho 48 inches (DN1200), le botenya ba lebitso ho tloha ho SCH 5S ho ea ho SCH XXS.
Butt welding e ka ba mokhoa o ikemetseng kapa oa matsoho o sebelisoang ho kopanya likotoana tsa tšepe hammoho. Lisebelisoa tsa ho tjheseletsa butt tsa forged hangata li bonolo; li entsoe e le hore li khone ho chesetsoa ka ho toba hore li kenelle sebakeng se seng. Leha ho le joalo, ho nahanoa ka sena, li hloka ho ntlafatsoa ho ea boemong bo itseng e le hore li ka kenngoa ka mokhoa o nepahetseng ho lisebelisoa tse ling.
Mokhoa oa tlhahiso:
Tekanyetso ena e totobatsa mekhoa ea ho etsa lisebelisoa tsa tšepe tse cheselitsoeng le tse se nang moeli.
Bakeng sa lisebelisoa tse cheselitsoeng, lits'ebetso tsa tlhahiso li kenyelletsa ho theha ho bata, ho etsa ho chesa, ho cheselletsa, joalo-joalo;
Bakeng sa lisebelisoa tsa liphaephe tse se nang moeli, mokhoa oa ho etsa tlhahiso hangata o etsoa ka ho bilika ho chesang, ho taka ka mokhoa o batang kapa ho otla ka litebele tse batang.
Litlhoko tsa lintho tse bonahalang:
Tekanyetso e totobatsa litlhoko tsa thepa bakeng sa lisebelisoa tsa liphaephe, tse koahelang carbon steel, tšepe e sa hloekang, tšepe ea alloy, joalo-joalo. Thepa ea lisebelisoa tsa liphaephe e tlameha ho kopana le lik'hemik'hale, ts'ebetso ea mechine le litlhoko tsa thepa ea 'mele tse boletsoeng ho standard.
Tlhahlobo le liteko:
TheASME B16.9 e tloaelehilenge hloka litlhahlobo le liteko tse fapaneng holim'a lisebelisoa tsa liphaephe tse hlahisitsoeng ho netefatsa hore boleng le ts'ebetso ea tsona li fihlela litlhoko tse boletsoeng maemong.
Litlhahlobo le liteko tsena li kenyelletsa tlhahlobo ea maemo, tlhahlobo ea pono, tlhahlobo ea sebopeho sa lik'hemik'hale, tlhahlobo ea ts'ebetso ea mochini, jj.
Tekanyetso ea ASME B16.9 e fana ka referense ea bohlokoa bakeng sa moralo le kaho ea sistimi ea lipeipi. E etsa bonnete ba hore boholo, tlhahiso le thepa ea lisebelisoa tsa liphaephe li finyella litlhoko tsa boenjiniere ho netefatsa polokeho le botšepehi ba tsamaiso ea liphaephe. Ha u sebelisa le ho khetha lisebelisoa tsa liphaephe, ho tlameha ho lateloe maemo a ASME B16.9 ho netefatsa ts'ebetso e tloaelehileng ea tsamaiso ea liphaephe.
