ASTM A234 WPB Carbon Steel Pipe Caps
Carbon steel taub hau (pipe cap), tseem hu ua plug, cap, yeeb nkab cover, dig muag lub taub hau, yog siv los kaw cov kav dej. Nws txoj haujlwm yog tib yam li cov yeeb nkab ntsaws, tab sis lub hau yeeb nkab tuaj yeem txuas ncaj qha mus rau cov yeeb nkab yam tsis tas yuav tsum muaj lwm yam fittings. Cov yeeb nkab cap suav nrog kev tsim cov yeeb nkab convex cap, conical plhaub, qhov sib txawv ntawm txoj kab uas hla, lub hau npog thiab lub qhov ncauj nruj.
Convex pipe caps muaj xws li hemispherical pipe caps, elliptical pipe caps, disc-shaped pipe caps, thiab spherical cap shaped pipe caps. Los ntawm qhov kev xav ntawm kev quab yuam, lub hau hemispherical nyob rau hauv lub convex cap yog maj mam ua tsis tshua muaj siab, tab sis los ntawm qhov kev xav ntawm kev tsim nyuaj, nws yog maj mam ua yooj yim los tsim.
Lub vuam seam kev taw qhia thaum lub sij hawm splicing tsuas yog tso cai rau radial thiab circumferential. Nyob rau hauv lub neej yav tom ntej, qhov kev xav tau no yuav raug muab tso tseg rau cov kav dej loj. Qhov kev ncua deb ntawm splicing yuav tsum tau ntau tshaj 3 δ thiab tsis tsawg tshaj li 100 hli (lub vuam tshav kub cuam tshuam cheeb tsam yog ib tug siab kev nyuaj siab cheeb tsam, thiab cov tshuaj muaj pes tsawg leeg nyob rau hauv cheeb tsam no yuav raug hlawv. zones, uas muaj feem xyuam rau cov tuab raws li kev ua tau zoo, qhov ntev ntawm qhov kev ntxhov siab yuav tsum siab dua 3 δ thiab tsis tsawg dua 100mm). Tab sis cov khoom siv tub yees yog qhov nyuaj kom ua tau raws li qhov yuav tsum tau ua thiab muaj nws tus kheej tshwj xeeb.
