Chiyambi

PoyerekezaMiyezo ya ASTM A276 vs ASTM A479 Stainless Steel Bar, ogula ayenera kusankha ASTM A276 ya zitsulo zosapanga dzimbiri ndi mawonekedwe omwe amagwiritsidwa ntchito popanga makina, ma shaft, zomangira, ndodo, zigawo za kapangidwe ndi zigawo zamafakitale, pomwe ASTM A479 ndi yoyenera kwambiri ngati zitsulo zosapanga dzimbiri zimapangidwira ma boiler, zotengera zopanikizika, zida zopanikizika, ma valve, mapampu ndi ntchito yotentha kwambiri kapena yokhudzana ndi kupanikizika. Miyezo yonseyi imatha kuphimba mitundu yambiri yofanana ya zitsulo zosapanga dzimbiri, koma ASTM A479 imapemphedwa kwambiri pamapulojekiti okhudzana ndi kupanikizika komwe kungafunike kugwiritsa ntchito molimbika, kutsimikizira kwamakina, momwe mankhwala otenthetsera kutentha ndi kuwongolera zikalata.

Pakugula koyenera, ASTM A276 ndi ASTM A479 si zipangizo ziwiri zosiyana zachitsulo chosapanga dzimbiri. Ndi miyezo yosiyana ya zinthu zomwe zimafotokoza mipiringidzo ndi mawonekedwe achitsulo chosapanga dzimbiri kuti zigwiritsidwe ntchito mosiyanasiyana. Kusankha komaliza kwa zinthu kumadalirabe mtundu, nambala ya UNS, kapangidwe ka mankhwala, mawonekedwe a makina, malo okhala ndi dzimbiri, kutentha, m'mimba mwake, kutha kwa pamwamba, kulolerana, EN 10204 3.1 MTC, kuwongolera kuchuluka kwa kutentha, kuyesa kwa PMI, kuyesa kwa UT ndi zofunikira zowunikira za chipani chachitatu.

SAKY STEEL imapereka bala lozungulira lachitsulo chosapanga dzimbiri, bala lathyathyathya, bala lalikulu, bala la hex, bala lopangidwa ndi bala lodulidwa mwapadera malinga ndi ASTM A276, ASTM A479, EN, DIN, JIS ndi GB. Bukuli likufotokoza kusiyana kwakukulu pakati pa ASTM A276 ndi ASTM A479, momwe mungasankhire muyezo woyenera, magiredi omwe nthawi zambiri amaperekedwa, ndi zomwe ogula ayenera kutsimikizira asanayike oda.

Kodi Miyezo ya ASTM A276 ndi ASTM A479 Stainless Steel Bar ndi Chiyani?

ASTM A276 ndi muyezo wokhazikika wa mipiringidzo ndi mawonekedwe a chitsulo chosapanga dzimbiri. Imagwiritsidwa ntchito kwambiri pogula mipiringidzo yachitsulo chosapanga dzimbiri m'mafakitale, kuphatikizapo mipiringidzo yozungulira, mipiringidzo ya sikweya, mipiringidzo ya hex, mipiringidzo yathyathyathya ndi mawonekedwe ena. Ogula nthawi zambiri amagwiritsa ntchito ASTM A276 pa mipiringidzo yachitsulo chosapanga dzimbiri yomwe imagwiritsidwa ntchito popanga makina, ma shaft, mabolts, mtedza, ndodo, ma valve stems, mapampu, zolumikizira, zothandizira ndi zida zina zaukadaulo.

ASTM A479 ndi muyezo wokhazikika wa zitsulo zosapanga dzimbiri ndi mawonekedwe omwe amagwiritsidwa ntchito mu ma boiler ndi ziwiya zina zopanikizira. Nthawi zambiri imasankhidwa pamene zitsulo zosapanga dzimbiri zimagwiritsidwa ntchito mu zida zopanikizira, ntchito yotentha kwambiri, zida zosungira kupanikizika, zida zopangira, kupanga magetsi, mafakitale a petrochemical, ma valve ndi makina opopera. M'mapulojekiti ambiri, ASTM A479 imatchulidwa chifukwa wogwiritsa ntchito amafuna kulumikizana kwamphamvu kwa zikalata ndi ntchito yokhudzana ndi kupanikizika.

Mafunso Ofunsidwa Kawirikawiri Zokhudza Miyezo ya Mipiringidzo ya Chitsulo Chosapanga Dzimbiri ya ASTM A276 vs ASTM A479

1. Kodi kusiyana kwakukulu pakati pa ASTM A276 ndi ASTM A479 ndi kotani?

ASTM A276 imaphimba zitsulo zosapanga dzimbiri ndi mawonekedwe kuti zigwiritsidwe ntchito nthawi zonse. ASTM A479 imaphimba zitsulo zosapanga dzimbiri ndi mawonekedwe a ma boiler ndi ziwiya zina zopanikizira. Kusiyana kwakukulu ndi kuchuluka kwa momwe amagwiritsidwira ntchito, makamaka ntchito yokhudzana ndi kupanikizika ya ASTM A479.

2. Kodi ASTM A276 ndi ASTM A479 zingaphimbe chitsulo chosapanga dzimbiri chofanana?

Inde, magiredi ambiri akhoza kupezeka pansi pa miyezo yonse iwiri, monga 304, 316, 316L, 321 ndi magiredi ena achitsulo chosapanga dzimbiri. Komabe, wogula ayenera kutsimikizira ngati polojekitiyo ikufuna A276, A479 kapena ASME SA479 mwachindunji.

3. Ndi muyezo uti womwe uyenera kugwiritsidwa ntchito pa bala lozungulira lachitsulo chosapanga dzimbiri?

Pazitsulo zosapanga dzimbiri zosapanga dzimbiri zomwe zimagwiritsidwa ntchito popanga makina, shafts, ndodo ndi zomangira, ASTM A276 imagwiritsidwa ntchito kwambiri. Pazitsulo zomangira zopopera mphamvu, ma boilers, ma valves, mapampu kapena zida zopopera mphamvu, ASTM A479 kapena ASME SA479 zingakhale zoyenera kwambiri.

4. Kodi ASTM A479 ndi yokwera mtengo kuposa ASTM A276?

Mtengo umadalira mtundu, kukula, mawonekedwe, kuyang'anira, kuchuluka ndi zofunikira pa zolemba. Mapulojekiti a ASTM A479 angafunike zolemba zovuta kapena macheke ena, zomwe zingakhudze mtengo. Komabe, mtundu wa zinthu ndi kuchuluka kwa mayeso nthawi zambiri zimakhudza mtengo kuposa nambala yokhazikika yokha.

5. Kodi ndi satifiketi iti yomwe ogula ayenera kupempha?

Ogula ayenera kupempha EN 10204 3.1 MTC yosonyeza muyezo wa ASTM, giredi, nambala ya UNS, nambala ya kutentha, kapangidwe ka mankhwala, mawonekedwe a makina, kukula, momwe kutentha kumakhalira komanso zotsatira za kuwunika. Kuyesa kwa PMI, kuyesa kwa UT, kuyesa kuuma ndi kuwunika kwa anthu ena kungapemphedwenso pa maoda ofunikira.

6. Kodi ASTM A276 ingagwiritsidwe ntchito m'malo mwa ASTM A479?

Pokhapokha ngati mwini pulojekiti, mainjiniya kapena kasitomala avomereza kusinthaku. Ngati mfundo yogulira kapena kujambula kukufunika ASTM A479 kapena ASME SA479, ASTM A276 siyenera kusinthidwa popanda chilolezo cholembedwa, makamaka pamapulojekiti okhudzana ndi kukakamizidwa.

7. Ndi mfundo ziti zomwe zimafunika kuti munthu apereke mawu ofulumira?

RFQ yonse iyenera kukhala ndi muyezo wa ASTM, giredi, nambala ya UNS, mawonekedwe a bala, m'mimba mwake kapena miyeso, kutalika, kuchuluka, kutha kwa pamwamba, kulekerera, momwe kutentha kumakhalira, zofunikira pakuyesa, zofunikira pa MTC, doko lopitako ndi zofunikira pakulongedza. Mwachitsanzo: ASTM A479 UNS S31603 316L bala lozungulira lachitsulo chosapanga dzimbiri, m'mimba mwake 40 mm, kutalika kwake 3000 mm, pamwamba pake peeled, EN 10204 3.1 MTC ndi PMI mayeso amafunika.

Mapeto

ASTM A276 ndi ASTM A479 zonse ndi miyezo yofunika kwambiri ya mipiringidzo yachitsulo chosapanga dzimbiri, koma imagwiritsidwa ntchito pazinthu zosiyanasiyana zogwiritsira ntchito. ASTM A276 imagwiritsidwa ntchito kwambiri pa mipiringidzo ndi mawonekedwe achitsulo chosapanga dzimbiri, pomwe ASTM A479 nthawi zambiri imafunika pa mipiringidzo yomwe imagwiritsidwa ntchito mu ma boiler, zotengera zamphamvu ndi zida zokhudzana ndi kupanikizika. Kusankha kolondola kumadalira kugwiritsa ntchito komaliza, zofunikira zojambula, khodi ya polojekiti ndi zofunikira za satifiketi.

Kuti zinthu ziyende bwino, ogula ayenera kutsimikizira muyezo wa ASTM, mtundu wa chitsulo chosapanga dzimbiri, nambala ya UNS, mawonekedwe a bala, kukula, kumalizidwa kwa pamwamba, momwe kutentha kumakhalira, EN 10204 3.1 MTC, kuwongolera kuchuluka kwa kutentha, kuyesa kwa PMI, kuyesa kwa UT, kuyang'anira miyeso ndi kulongedza kunja. Katswiri wopereka zitsulo zosapanga dzimbiri ayenera kuthandiza ogula kusankha muyezo woyenera komanso mtundu malinga ndi kukana dzimbiri, mphamvu, ntchito yokakamiza, mtengo ndi zofunikira zotumizira.

Pemphani Mtengo

Lumikizanani nafe kuti mupeze mtengo wogulira zinthu, MTC, PMI, kukula kosinthidwa, kumalizidwa kwa pamwamba, kulongedza katundu kunja, ndi chithandizo chotumizira.
