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 zosasunthika zolumikizirana ndikusintha momwe amayendera ndi kukula kwake.mapaipim'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 ma elbows, zochepetsera, mapaipi ofanana m'mimba mwake, ma flanges, ma tee, mitanda, ndi zina zambiri, polumikiza ndikusintha njira ndi kukula kwa mapaipi.
Muyezowu umanena za kuchuluka kwazomwezi, kuchokera pa 1/2 inchi (DN15) mpaka mainchesi 48 (DN1200), komanso makulidwe oyambira SCH 5S mpaka SCH XXS.

Kuwotcherera matako kumatha kukhala njira yodzichitira yokha 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 pazowonjezera zina.

Njira yopanga:

Muyezo uwu umatchula njira zopangira zitsulo zowotcherera komanso zopanda msoko.
Zopangira zowotcherera, njira zopangira zimaphatikizira kuzizira, kupanga kutentha, kuwotcherera, etc.;
Pazoyikapo zitoliro zopanda msoko, njira yopangira nthawi zambiri imakhala ndi 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. Zinthu zazitsulo zazitsulo ziyenera kukwaniritsa zomwe zimapangidwa ndi mankhwala, makina ogwiritsira ntchito komanso zofunikira za katundu zomwe zatchulidwa muyeso.

Kuyang'anira ndi kuyesa:

TheASME B16.9 muyezoamafuna kuyendera zosiyanasiyana ndi mayesero pa zovekera opangidwa chitoliro kuonetsetsa kuti khalidwe lawo ndi ntchito zikugwirizana ndi zofunika za 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 zoyikira mapaipi, mulingo wa ASME B16.9 uyenera kutsatiridwa kuti zitsimikizire kuti mapaipi akuyenda bwino.
