Reducer ndi cholumikizira chitoliro chomwe chimagwiritsidwa ntchito polumikizira mapaipi ndi kulumikizana ndi zida.Ikhoza kulumikiza mapaipi amitundu yosiyanasiyana kuti akwaniritse kufalikira kwamadzi kapena mpweya.
Pofuna kuwonetsetsa kuti zabwino, chitetezo ndi kusinthana kwa ochepetsera, International Organisation for Standardization (ISO) ndi mabungwe ena ofunikira atulutsa miyeso yapadziko lonse lapansi yomwe ikukhudza mbali zonse za mapangidwe, kupanga ndi kugwiritsa ntchito zochepetsera.
Izi ndi zina mwamiyezo yayikulu padziko lonse lapansi yokhudzana ndi zochepetsera:
- ASME B16.9-2020- Zopangira Zowotcherera Zopangidwa Ndi Factory-Made Wrought Butt: The American Society of Mechanical Engineers (ASME) idasindikiza mulingo uwu, womwe umaphatikizapo kapangidwe kake, miyeso, kulolerana ndi mawonekedwe azinthu zamapaipi, komanso njira zoyesera zofananira.Muyezo uwu umagwiritsidwa ntchito kwambiri pamakina a mapaipi a mafakitale komanso umagwiranso ntchito kwa ochepetsa.
Zofunikira pakupanga: Muyezo wa ASME B16.9 umafotokoza mwatsatanetsatane zofunikira zamapangidwe a Reducer, kuphatikiza mawonekedwe, kukula, geometry ndi mawonekedwe a magawo olumikizira.Izi zimatsimikizira kuti Reducer idzakwanira bwino mu ductwork ndikusunga kukhazikika kwake.
Zofunikira zakuthupi: Muyezo umanena za zinthu zomwe zimafunikira kupanga Reducer, nthawi zambiri zitsulo za carbon, zitsulo zosapanga dzimbiri, zitsulo za alloy, ndi zina zotero. Zimaphatikizapo kupanga mankhwala, makina ndi zofunikira za kutentha kwa zinthuzo kuti zitsimikizire kuti chotsitsacho chili ndi mphamvu zokwanira. ndi kukana dzimbiri.
Njira yopangira: Muyezo wa ASME B16.9 umaphatikizapo njira yopangira Reducer, kuphatikizapo kukonza zinthu, kupanga, kuwotcherera ndi kutentha.Njira zopangira izi zimatsimikizira ubwino ndi ntchito ya Reducer.
Makulidwe ndi kulolerana: Mulingo umanena za kukula kwa Zochepetsera ndi zofunikira zololera kuti zitsimikizire kusinthasintha pakati pa Zochepetsera zopangidwa ndi opanga osiyanasiyana.Izi ndizofunikira kuti zitsimikizire kusasinthika ndi kusinthasintha kwa machitidwe a mapaipi.
Kuyesa ndi kuwunika: ASME B16.9 imaphatikizanso zofunikira zoyeserera ndi zowunikira kuti chochepetsera chitsimikizire kuti chikhoza kugwira ntchito motetezeka komanso modalirika pakugwiritsa ntchito kwenikweni.Mayesowa nthawi zambiri amaphatikiza kuyesa kukakamiza, kuyang'anira weld, komanso kuyesa magwiridwe antchito.
- DIN 2616-1: 1991- Zitoliro zazitsulo zowotcherera matako;zochepetsera kuti zigwiritsidwe ntchito pamavuto athunthu: Muyezo woperekedwa ndi Germany Industrial Standards Organisation (DIN) womwe umafotokozera kukula, zofunikira ndi zoyeserera za zochepetsera zomwe zimagwiritsidwa ntchito pakukakamizidwa kwathunthu.
Muyezo wa DIN 2616 umafotokoza mwatsatanetsatane zofunikira zamapangidwe a Reducer, kuphatikiza mawonekedwe ake, kukula kwake, geometry ndi mawonekedwe a magawo olumikizira.Izi zimatsimikizira kuti Reducer idzakwanira bwino mu ductwork ndikusunga kukhazikika kwake.
Zofunika zakuthupi: Muyezo umatanthawuza miyezo ya zinthu zomwe zimafunikira pomanga chochepetsera, nthawi zambiri chitsulo kapena zida zina za alloy.Zimaphatikizapo kupanga mankhwala, makina ndi zofunikira zothandizira kutentha kwa zinthuzo kuti zitsimikizire kuti chochepetsera chimakhala ndi mphamvu zokwanira komanso kukana dzimbiri.
Njira Yopangira: Muyezo wa DIN 2616 umakhudza njira yopangira Reducer, kuphatikiza kukonza, kupanga, kuwotcherera ndi kutentha kwazinthu.Njira zopangira izi zimatsimikizira ubwino ndi ntchito ya Reducer.
Makulidwe ndi kulolerana: Mulingo umanena za kukula kwa Zochepetsera ndi zofunikira zololera kuti zitsimikizire kusinthasintha pakati pa Zochepetsera zopangidwa ndi opanga osiyanasiyana.Izi ndizofunikira makamaka chifukwa mapulojekiti osiyanasiyana angafunike zochepetsera mosiyanasiyana.
Kuyesa ndi kuyang'anira: DIN 2616 imaphatikizanso zofunikira zoyesa ndikuwunika kwa Reducer kuti zitsimikizire kuti zitha kugwira ntchito motetezeka komanso modalirika pakugwiritsa ntchito kwenikweni.Mayesowa nthawi zambiri amaphatikiza kuyesa kukakamiza, kuyang'anira weld, komanso kuyesa magwiridwe antchito.
- Mtengo wa GOST 17378muyezo ndi gawo lofunika kwambiri la Russian national standardization system.Imatchula zofunikira za mapangidwe, kupanga ndi machitidwe a zochepetsera.Chochepetsera ndi cholumikizira chitoliro chomwe chimagwiritsidwa ntchito kulumikiza mapaipi awiri amitundu yosiyanasiyana mu mapaipi ndikulola madzimadzi kapena gasi kuyenda momasuka pakati pa mapaipi awiriwo.Mtundu uwu wa kugwirizana kwa chitoliro nthawi zambiri umagwiritsidwa ntchito kusintha kayendedwe, kupanikizika ndi kukula kwa machitidwe a mapaipi kuti akwaniritse zofunikira za polojekiti.
Zomwe zili mu Reducer pansi pa GOST 17378 standard
Muyezo wa GOST 17378 umatchula zinthu zingapo zofunika zochepetsera, kuphatikiza koma osachepera izi:
Zofunikira pakupanga: Mulingo uwu umafotokoza mwatsatanetsatane zofunikira za kapangidwe ka chochepetsera, kuphatikiza mawonekedwe, kukula, makulidwe a khoma ndi mawonekedwe a gawo lolumikizira chochepetsera.Izi zimatsimikizira kuti chochepetsera chidzakwanira bwino mu dongosolo la mapaipi ndikukhalabe okhazikika.
Zofunikira pazakuthupi: Muyezo umanena za zinthu zomwe zimafunikira pakupanga zochepetsera, kuphatikiza mtundu wa chitsulo, kapangidwe kake, makina amakina ndi zofunikira zochizira kutentha.Zofunikira izi zimapangidwira kuti zitsimikizire kulimba kwa chochepetsera komanso kukana dzimbiri.
Njira yopanga: GOST 17378 mwatsatanetsatane njira yopangira chochepetsera, kuphatikiza kukonza, kupanga, kuwotcherera ndi kutentha kwazinthu.Izi zimathandiza opanga kuonetsetsa kuti ochepetsera khalidwe ndi ntchito.
Makulidwe ndi kulolerana: Mulingo umanena za kukula kwa zochepetsera ndi zofunikira zololera kuti zitsimikizire kusinthasintha pakati pa zochepetsera zopangidwa ndi opanga osiyanasiyana.
Kuyesa ndi kuyang'anira: GOST 17378 imaphatikizanso zofunikira zoyesa ndi zowunikira kwa ochepetsera kuti awonetsetse kuti amagwira ntchito motetezeka komanso modalirika pakugwiritsa ntchito kwenikweni.Mayesowa akuphatikiza kuyesa kukakamiza, kuyang'anira weld ndi kuyesa magwiridwe antchito.
Malo ogwiritsira ntchito ochepetsera
Otsitsa pansi pa muyezo wa GOST 17378 amagwiritsidwa ntchito kwambiri pamapaipi amafuta, gasi ndi mafakitale aku Russia.Maderawa ali ndi magwiridwe antchito okhwima komanso zofunika kwambiri pakulumikiza mapaipi, chifukwa kukhazikika kwa magwiridwe antchito ndi chitetezo cha njira zamapaipi ndizofunikira kwambiri pachuma cha dziko komanso mphamvu zamagetsi.Ochepetsera amagwira ntchito yofunika kwambiri pakusintha kayendetsedwe kake, kupanikizika ndi kukula kwa mapaipi, ndipo kupanga ndi kugwiritsa ntchito kwawo mogwirizana ndi miyezo ya GOST 17378 kumathandiza kuonetsetsa kuti machitidwe a mapaipi akuyenda bwino.
Mwachidule, Reducer pansi pa muyezo wa GOST 17378 ndi gawo lofunikira pagawo laumisiri wamapaipi aku Russia.Imatchulanso mapangidwe, kupanga ndi ntchito zofunikira za ochepetsera, kuwonetsetsa ubwino ndi kudalirika kwa malumikizidwe a mapaipiwa muzogwiritsira ntchito zosiyanasiyana.Mulingo uwu umathandizira kuti Russia ikhalebe yokhazikika pamapaipi ake kuti ikwaniritse zosowa zapakhomo ndi zapadziko lonse lapansi, kupereka chithandizo chofunikira pachuma cha dzikolo komanso mphamvu zamagetsi.
