ANSI/ASME B16.9 ndi muyeso womwe umakwirira zopangira zopangidwa ndi fakitale zamakero a NPS 1/2 mpaka NPS 48 (DN 15 mpaka DN 1200). Imodzi mwa mitundu yodziwika bwino ya zowotcherera pamatako zomwe zafotokozedwa mu muyezo uwu ndi Equal Tee ndi Reducing Tee. Nawa mawu oyamba a ANSI/ASME B16.9 zowotcherera matako a Equal Tee ndi Reducing Tee:
1. Equal Tee:
- Tee Equal ndi mtundu wa kuwotcherera matako komwe kumakhala ndi mipata itatu yofanana yolumikizira chitoliro munjira ziwiri pamakona a digirii 90.
- ANSI/ASME B16.9 imatchula kukula, kulolerana, zofunikira zakuthupi, ndi njira zoyesera za Equal Tees.
- Ma Tee Ofanana amagwiritsidwa ntchito kwambiri pamakina a mapaipi kuti agawire madzi oyenda mofanana mbali zosiyanasiyana, kupereka kugawa koyenera.
2. Kuchepetsa Tee:
- Kuchepetsa Tee ndi mtundu wa matako-wowotcherera omwe ali ndi chotsegula chimodzi chachikulu kuposa ena awiri, kulola kulumikiza mapaipi amitundu yosiyanasiyana mu mgwirizano wa nthambi.
- ANSI/ASME B16.9 imatanthawuza miyeso, mawonekedwe azinthu, ndi zofunikira zopangira Kuchepetsa Tees.
- Kuchepetsa Tees kumagwiritsidwa ntchito ngati pakufunika kuphatikizira mapaipi amitundu yosiyanasiyana kapena kuchuluka kwamayendedwe pamapaipi.
3. Kutsata Kwanthawi Zonse:
- Zipangizo za ANSI/ASME B16.9 zowotcherera matako zimagwirizana ndi miyezo ya American National Standards Institute (ANSI) ndi American Society of Mechanical Engineers (ASME) yopangira mapaipi.
- Zopangira izi zidapangidwa kuti zizigwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza mafuta ndi gasi, petrochemical, kupanga magetsi, ndi malo opangira madzi.
4. Zida ndi Zomangamanga:
- ANSI/ASME B16.9 zowotcherera matako za Equal Tee ndi Reducing Tee zimapezeka muzinthu zosiyanasiyana monga chitsulo cha kaboni, chitsulo chosapanga dzimbiri, ndi chitsulo cha aloyi kuti zigwirizane ndi ntchito zosiyanasiyana.
- Zopangirazo zitha kupangidwa pogwiritsa ntchito njira zomangira zopanda msoko kapena zowotcherera, kutengera zinthu, kukula, komanso kukakamizidwa.
5. Kuyika ndi kuwotcherera:
- ANSI/ASME B16.9 Tee Equal Tee ndi Reducing Tee zopangira zidapangidwa kuti zikhazikitse matako, kuwonetsetsa kulumikizana kolimba komanso kopanda kutayikira pakati pa mapaipi.
- Njira zowotcherera moyenera, kuphatikiza kukonzekera, kuyanjanitsa, ndi njira zowotcherera, ziyenera kutsatiridwa kuti mupeze mgwirizano wodalirika.
Mwachidule, ANSI/ASME B16.9 zowotcherera matako za Equal Tee ndi Reducing Tee zimagwira ntchito yofunika kwambiri pamapaipi popangitsa kuti nthambi ndi kuphatikiza mapaipi azikhala otetezeka komanso ogwira mtima. Zosakaniza izi zimapangidwira kuti zigwirizane ndi miyezo yamakampani ndi mafotokozedwe, kupereka kugawa kodalirika komanso njira zolumikizirana pamafakitale osiyanasiyana.
