ASME B16.9: Miyezo Yapadziko Lonse ya Zowotcherera Zopangira Matako

Muyezo wa ASME B16.9 ndi muyeso woperekedwa ndi American Society of Mechanical Engineers (ASME) wamutu wakuti “Factory-Made Wrought SteelZopangira zowotcherera matako“.Mulingo uwu umanenanso zofunikira pamiyeso, njira zopangira, zida, ndi kuwunika kwazitsulo zowotcherera komanso zosawoneka bwino zolumikizirana ndikusintha mayendedwe ndi kukula kwamapaipim'machitidwe a mapaipi.

Imawonetsanso zomwe zili mulingo wa ASME B16.9:

Kuchuluka kwa ntchito:

Muyezo wa ASME B16.9 umagwira ntchito pazitsulo zowotcherera ndi zitsulo zosasunthika, kuphatikiza zigongono, zochepetsera, mapaipi ofanana, ma flanges, ma tee, mitanda, ndi zina zambiri, polumikiza ndikusintha momwe mapaipi amayendera.
Muyezowu umatchula zamitundu yosiyanasiyana ya zotengera izi, kuchokera pa 1/2 inchi (DN15) mpaka mainchesi 48 (DN1200), ndi makulidwe mwadzina kuchokera ku SCH 5S mpaka SCH XXS.

Kuwotcherera matako kumatha kukhala njira yokhayo kapena yamanja yomwe imagwiritsidwa ntchito kulumikiza zidutswa zachitsulo palimodzi.Zopangira zowotcherera matako nthawi zambiri zimakhala zosavuta;amapangidwa m'njira yakuti athe kuwotcherera molunjika ku chinthu china.Komabe, poganizira izi, amayenera kupangidwa kuti akhale ndi muyezo wina kuti athe kuyikidwa bwino ndi zida zina.

Njira yopanga:

Muyezo uwu umatchula njira zopangira zitsulo zowotcherera komanso zopanda msoko.
Zopangira zowotcherera, njira zopangira zimaphatikizira kuzizira, kupanga kutentha, kuwotcherera, etc.;
Kwa zida zopangira zitoliro zopanda msoko, njira yopangira nthawi zambiri imakhala pogwiritsa ntchito kugudubuza kotentha, kujambula kozizira kapena kukhomerera kozizira.

Zofunikira:

Muyezo umatanthawuza zofunikira zazitsulo zopangira zitoliro, zophimba zitsulo za carbon, zitsulo zosapanga dzimbiri, zitsulo za aloyi, ndi zina zotero. Zomwe zimapangidwira pazitsulo ziyenera kukwaniritsa zomwe zimapangidwa ndi mankhwala, makina ogwira ntchito komanso zofunikira za katundu zomwe zatchulidwa muyeso.

Kuyang'anira ndi kuyesa:

TheASME B16.9 muyezoamafuna kuyendera zosiyanasiyana ndi mayesero pa opangidwa chitoliro zovekera kuonetsetsa kuti khalidwe lawo ndi ntchito zikugwirizana ndi zofunika za mu muyezo.
Kuyang'anira ndi kuyesaku kumaphatikizapo kuwunika kowoneka bwino, kuyang'ana kowoneka bwino, kusanthula kwamankhwala, kuyesa kwamakina, ndi zina zambiri.

Muyezo wa ASME B16.9 umapereka chidziwitso chofunikira pamapangidwe ndi kapangidwe ka mapaipi.Zimatsimikizira kuti kukula, kupanga ndi zinthu zazitsulo zapaipi zimakwaniritsa zofunikira zaumisiri kuti zitsimikizire chitetezo ndi kudalirika kwa dongosolo la mapaipi.Mukamagwiritsa ntchito ndikusankha zopangira mapaipi, mulingo wa ASME B16.9 uyenera kutsatiridwa kuti zitsimikizire kuti mapaipi akuyenda bwino.
