Iyo ASME B16.9 chiyero chiyero chakapihwa neAmerican Society of Mechanical Engineers (ASME) ine musoro unoti "Factory-Made Wrought Steel.Butt-welding Fittings“. Iyi chiyero inotsanangudza zvinodikanwa zvehukuru, nzira dzekugadzira, zvigadzirwa, uye kuongororwa kwesimbi yakashongedzwa uye isina musono chiyero chimiro chekubatanidza uye kushandura gwara uye saizi ye.mapaipimumapiping systems.
Inosumawo izvo zvikuru zvemukati uye maitiro eiyo ASME B16.9 standard:
Chikamu chekushandisa:
Iyo ASME B16.9 chiyero chinoshanda kune simbi yakashongedzwa uye isina musono chiyero chechimiro pombi fittings, kusanganisira magokora, zvinoderedza, akaenzana dhayamita mapaipi, flanges, tees, michinjikwa, nezvimwewo, yekubatanidza nekushandura gwara uye saizi yemapombi.
Chiyero chinotsanangura dhayamita yezita rezviyero izvi, kubva pa1/2 inch (DN15) kusvika 48 inches (DN1200), uye ukobvu hwezita kubva kuSCH 5S kusvika kuSCH XXS.
Butt welding inogona kuita otomatiki kana yemanyorero maitiro anoshandiswa kubatanidza simbi zvidimbu pamwechete. Forged butt welding fittings kazhinji zviri nyore; dzakagadzirwa kuitira kuti dzigone kusungirirwa kune imwe fitting. Nekudaro, neizvi mupfungwa, ivo vanofanirwa kuvandudzwa kune imwe mwero kuitira kuti vagone kurongedzerwa kune zvimwe zvishongedzo.
Kugadzira nzira:
Iyi chiyero inotsanangura nzira dzekugadzira simbi yakashongedzwa uye isina musono yakajairwa maumbirwo emhando.
Zvekumisikidza zvakasungirirwa, maitiro ekugadzira anosanganisira kutonhora kuumba, kupisa kuumba, welding, nezvimwe;
Kune zvigadziriso zvepombi zvisina musono, maitiro ekugadzira anowanzo kuburikidza nekupisa kunoputika, kudhirowa kunotonhora kana kutonhora kunotonhora.
Zvinhu zvinodiwa:
Chiyero chinotsanangura zvinodiwa zvepombi fittings, kuvhara kabhoni simbi, simbi isina tsvina, alloy simbi, etc. Izvo zvinhu zvepombi fittings zvinofanira kusangana nemakemikari, mechanical performance uye pfuma yemuviri zvinodiwa zvinotsanangurwa muchiyero.
Kuongorora uye kuyedza:
TheASME B16.9 chiyeroinoda kuongororwa kwakasiyana uye bvunzo pane inogadzirwa pombi fittings kuti ive nechokwadi chekuti mhando yavo nekuita zvinosangana nezvinodiwa zvinotsanangurwa muyero.
Aya ekuongorora uye bvunzo anosanganisira dimensional yekuongorora, yekuona, kuongorora kwemakemikari kuumbwa, mechanical performance test, nezvimwe.
Iyo ASME B16.9 chiyero inopa yakakosha ratidziro yekugadzira uye kuvaka kwepombi system. Inovimbisa kuti saizi, kugadzira uye zvinhu zvepombi fittings zvinosangana nezvinodiwa zveinjiniya kuti ive nechokwadi chekuchengetedza uye kuvimbika kwepombi system. Paunenge uchishandisa nekusarudza pombi fittings, iyo ASME B16.9 standard inofanirwa kuteverwa kuti ive nechokwadi chekushanda kwakajairika kwepombi system.
