Carbon Steel National Standard Flange Gedhi Valve

Isu tiri nyanzvi yekugadzira valve yakabata ISO, API uye CE certification. Isu pachedu midziyo yekugadzira yepamusoro uye yakazara seti yemhando yekudzora masisitimu. Isu tinogashirawo maOEM neODM maodha, ane inochinjika yakaderera odha huwandu. Zvigadzirwa zvedu zvakavimbika zvinotengeswa kunze kwenyika uye zvinokunda kuzivikanwa kwakakura kubva kune vatengi.

Ndeapi akajairwa kabhoni simbi flange yegedhi mavharuvhu?

Carbon steel flanges inouya pasi pezviyero zvakasiyana zvichienderana nekuti uri kuishandisa kupi. Zvakajairwa zvinosanganisira ASME B16.5 (American standard), EN 1092-1 (European standard), uye GB/T 9113 series (Chinese national standard). Kune yedu kabhoni simbi yenyika standard flange gedhi mavharuvhu, isu tinowanzo kutevedzera GB zviyero kuti zvienderane epamba pombi masisitimu. Aya mazinga anotsanangura saizi yeflange, chiyero chekumanikidza, uye bolt hole pateni, saka vharafu inogona kukwana zvakakwana nemapombi ako uye kusangana neinodiwa kirasi yekumanikidza.

Ndezvipi zviyero zvinoshanda kumavharuvhu egedhi?

Mavharuvhu egedhi haasi ese akaitwa akafanana-anotevera zviyero zvakasiyana zvichienderana nekuti unoronga kuishandisa kupi uye sei. Pamabasa akaoma semafuta uye gasi refineries, API 600 ndiyo chiyero chikuru cheheavy-duty simbi gedhi mavharuvhu. ISO 6002 imwe chiyero chepasi rose chinowirirana neAPI 600 yemhando dzebhoneti dzakabhoti. Uye kune edu epamba uye akawanda mapurojekiti emaindasitiri, isu tinoshandisa China's GB/T 12234 yakajairwa. Imwe neimwe yemayero aya inotsanangura chaizvo kuti vharafu inofanira kugadzirwa sei, zvipi zvekushandisa, kuti inoedzwa sei kudzvanywa, uye zviyero zvauchawana. Nenzira iyo, iwe unoziva kuti vharuvhu inokodzera mutsara wako uye inomira yakachengeteka nekufamba kwenguva.

Ibasa rei iro flange inobata muvharuvhu yegedhi?

Iyo flange ndiyo inonyanya "kusangana kumeso" kumagumo egedhi revhavha. Ndizvo zvinokutendera kuti uvhare vharuvhu papombi yako kana zvimwe zvishandiso. Paunosunga mabhaudhi, flange inodzvanya zvakaenzana pagasket kugadzira chisimbiso chakasimba, chisingabvire. Izvi zvinoreva kuti hapana kusviba kwakashata, uye gare gare kana iwe uchida kutora vharafu kunze kuti igadziriswe kana kutsiva, zviri nyore kusunungura nekubvisa. Iyo flange inoparadzirawo kumanikidza kwekushanda zvakaenzana pamubatanidzwa, saka kubatana kunoramba kwakagadzikana kunyangwe iyo system iri pasi pemutoro.

Unogona here kutsanangura iyo API 600 yakajairwa?

API 600 yakanyatso kuoma, isina-nonsense mwero kubva kuAmerican Petroleum Institute. Yakagadzirirwa zvakanangana nebhoneti simbi yegedhi mavharuvhu - rudzi rwaunowana mumapaipi ekunatsa, oiri & gasi mapaipi, uye dzimwe dzinoda chaizvo nzvimbo dzeindasitiri.

Iyo haidimburi makona pane zvinodiwa: sarudzo dzezvinhu dzinofanirwa kuve dzakarurama, dhizaini inofanirwa kumira, kugadzira kunofanirwa kutevedzera mitemo yakasimba, uye vharafu yega yega inofanirwa kupfuura kudzvanywa uye kuvuza bvunzo isati yabuda mufekitori. Pfungwa yacho yose iri nyore: iva nechokwadi chokuti valve inogona kutora kudzvinyirira kukuru, kupisa kwakanyanya, uye midhiya yakaoma, uye ichiri kushanda paunenge uchida zvakanyanya. Kana vheji yegedhi ikasangana neAPI 600, unoziva kuti yakavakirwa zvakakosha, zvinoshanda nesimba.
