KODI ASME B16.9 STANDARD NDI CHIYANI?

Kodi ndi zinthu ziti zomwe zimagwiritsidwa ntchito powotcherera mapaipi?Zowotcherera matako, ndithudi.Koma kodi munayamba mwadzifunsapo chifukwa chake nthawi zambiri zimakhala zosavuta kupeza zopangira zomwe zimagwira ntchito?

Pankhani ya zowotcherera za butt zopangidwa ndi fakitale, pali miyezo yeniyeni yomwe imayenera kukwaniritsidwa panthawi yopanga.Odziwika kwambiri ndi ANSI ndi ASME.Tiyeni tiwone mulingo wa ASME B 16.9 ndi momwe umasiyana ndi mulingo wa ANSI.

ASME B 16.9:Zopangidwa ndi FakitaleZida zowotcherera za Butt Wrought

ASME B 16.9 imakhazikitsidwa ndi American Society of Mechanical Engineers.B 16.9 amatanthauza zowotcherera matako zopangidwa fakitale.ASME B 16.9 imayang'anira kukula, kuchuluka kwa mphamvu, kukula, kuyika chizindikiro, zinthu, miyeso yoyenera, mizere yapamtunda, kukonzekera komaliza, kuyesa kwa umboni wa mapangidwe, kuyesa kupanga, ndi kulekerera.Kuyimitsidwa uku kumawonetsetsa kuti zolumikizira zimapangidwa momwe ziyenera kukhalira komanso momwe zimakhalira, kupangitsa kuti zikhale zosavuta kuphatikiza magawo atsopano ndi magawo omwe alipo, ndikuwonetsetsa kuti chitetezo, mphamvu, ndi bata.

Kuwotchera matako kumatha kukhala kongopanga kapena kumanja, komwe kumagwiritsidwa ntchito kulumikiza zidutswa zachitsulo palimodzi.Zowotcherera pamatako nthawi zambiri zimakhala zosavuta;amapangidwa m'njira yakuti athe kuwotcherera molunjika pa cholumikizira china.Poganizira izi, komabe, ziyenera kukhazikitsidwa pamiyezo inayake, kuti zigwirizane bwino ndi zina.Mitundu ya ma weld weld fitting ingaphatikizepozigongono, zipewa, tee, ochepetsa, ndi zogulitsira.

Chifukwa chowotcherera ndi njira imodzi yodziwika bwino yowotcherera komanso njira zolumikizirana, akatswiri amakanika amatha kugwiritsa ntchito ndikugwira ntchito ndi zowotcherera zopangidwa ndi fakitale pafupipafupi.Opanga ma welds a butt weld adzafunika kukhudzidwa ndi miyezo ndi mawonekedwe.

Miyezo ya ANSI vs ASME

Miyezo ya ANSI vs ASME ya magawo ena opangidwa ndi fakitale imatha kusiyana.Chifukwa chake, mainjiniya angafune kudziwa ngati akugwira ntchito motsatira miyezo ya ANSI kapena ASME, popeza miyezo ya ASME nthawi zambiri imakhala yodziwika bwino ndipo miyezo ya ANSI imatha kukhala yophatikiza.ASME ndi muyeso womwe wakhala ukufotokoza za pipefitting kuyambira koyambirira kwa 1920s.Pazinthu zambiri, kutsatira miyezo ya ASME kudzatsatiranso miyezo ya ANSI.

ANSI idakhazikitsidwa ndi American National Standards Institute.ANSI imayang'anira mafakitale ambiri osiyanasiyana, pomwe ASME imapangidwira ma boilers, zotengera zokakamiza, ndi madera ena ofanana.Chifukwa chake, ngakhale china chake chingakwaniritse miyezo ya ANSI, sichingakwaniritse miyezo ya ASME;Miyezo ya ASME ikhoza kukhala yolunjika kwambiri kapena yovuta.Zikafika pamlingo wa B16.9, komabe, miyezo ya ANSI ndi ASME imakhala yofanana.

Miyezo ndi malamulo ndizofunika nthawi zonse, makamaka muzinthu zothamanga kwambiri monga ma pipefittings ndi boilers.Chifukwa miyezo ingasinthenso, ndikofunikira kuti mabungwe azipereka nthawi yosintha pazosintha ndi zowonjezera.Ku Steel Forgings, tikugwira ntchito nthawi zonse kuwonetsetsa kuti zidutswa zathu zikukwaniritsa zofunikira zonse - komanso kuti zipitirire mopitilira muyeso komanso kusasinthika.
