Pankhani ya zomangamanga ndi zomangamanga, kusankha zinthu ndizofunikira kuti zitsimikizire kukhulupirika ndi moyo wautali wa kapangidwe kake. Chimodzi mwazinthu zotere zomwe zapeza mbiri yamphamvu mumakampani ndiASTM A252 Gawo 2Mabomba a Pipe. Bulogu iyi ifufuza zatsatanetsatane, katundu, ndi zofunikira za ASTM A252 Grade 2 kuti mumvetse bwino za kufunikira kwake pantchito yomanga.
Kodi ASTM A252 Grade 2 ndi chiyani?
ASTM A252 ndiye muyeso wokhazikika wa milu yowotcherera komanso yopanda msoko pakugwiritsa ntchito maziko. Giredi 2 ndi imodzi mwa magiredi atatu omwe atchulidwa mu mulingo uwu, giredi 1 ndi yotsika kwambiri ndipo Sitandade 3 ndiyokwera kwambiri potengera mphamvu zokolola. Milu ya ASTM A252 Grade 2 tubular idapangidwa kuti ipereke mphamvu komanso kukhazikika, kuwapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana, kuphatikiza maziko akuya, zomanga zam'madzi, ndi zochitika zina zonyamula katundu.
Zinthu zazikulu za ASTM A252 Gulu la 2 zikuphatikiza mphamvu zokolola zochepa za 35,000 psi ndi mphamvu yocheperako ya 60,000 psi. Zinthu izi zimatsimikizira kuti miluyo imatha kupirira zolemetsa zazikulu komanso zopsinjika, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo ovuta.
ASTM A252 Gulu la 2 Mapaipi Olemba Mapaipi Zofunikira
Chofunikira pamilu ya ASTM A252 Grade 2 ndichofunika cholemba bwino. Mulu uliwonse uyenera kulembedwa bwino kuti upereke chidziwitso chofunikira chokhudza mankhwala. Kuyika chizindikirochi ndikofunikira pakutsatiridwa, kutsimikizika kwamtundu, komanso kutsatira miyezo yamakampani. Mfundo zotsatirazi ziyenera kuphatikizidwa polembapo:
1. Dzina la wopanga kapena mtundu: Izi zimazindikiritsa wopanga muluwo, kuwonetsetsa kuti wogwiritsa ntchito atha kutsata zomwe zidachokera.
2.Nambala Yotentha: Nambala ya kutentha ndi chizindikiritso chapadera chomwe chimaperekedwa ku gulu linalake lachitsulo. Zimalola kuti chiyambi ndi makhalidwe azinthu zizitsatiridwa, zomwe ndizofunika kuti pakhale ulamuliro wabwino.
3.Manufacturer Process: Izi zikuwonetsa njira yomwe imagwiritsidwa ntchito popangira mulu, kaya ndi welded kapena wopanda msoko. Kumvetsetsa njira yopangira zinthu kumathandizira kuwunika momwe muluwo umagwirira ntchito.
4.Spiral Joint Type: Mtundu wa olowa ozungulira omwe amagwiritsidwa ntchito mumulu wa pipeziyenera kulembedwa, ngati kuli kotheka. Chidziwitso ichi ndi chofunikira kuti timvetsetse kukhulupirika kwa muluwo.
5.Outer Diameter: Mbali yakunja ya muluyo iyenera kulembedwa momveka bwino chifukwa ndi gawo lofunika kwambiri pakuyika ndi kuwerengera katundu.
6.Kuchuluka kwa khoma la dzina: Kuchuluka kwa khoma la mulu ndi muyeso wina wofunikira womwe umakhudza mphamvu zake ndi kubereka.
7.Utali ndi kulemera pa utali: Utali wonse ndi kulemera kwa mulu uliwonse uyenera kufotokozedwa. Chidziwitso ichi ndi chofunikira pakukonzekera ndi kukonza.
8.Mafotokozedwe a Dzina ndi Kalasi: Pomaliza, kuyika chizindikiro kuyenera kukhala ndi dzina lodziwika bwino (ASTM A252) ndi giredi (Giredi 2) kuti zitsimikizire kuti zikutsatira miyezo yamakampani.
Pomaliza
Milu ya Mapaipi a ASTM A252 Gulu la 2 ndi gawo lofunikira pakumanga kwamakono, kupereka mphamvu ndi kulimba kofunikira pazogwiritsa ntchito zosiyanasiyana. Kumvetsetsa zofunikira ndikuyika chizindikiro ndikofunikira kwa mainjiniya, makontrakitala, ndi oyang'anira projekiti kuti awonetsetse kuti akugwiritsa ntchito zida zoyenera pantchito zawo. Potsatira mfundozi, makampani omangamanga amatha kukhalabe ndi machitidwe apamwamba ndikuwonetsetsa chitetezo ndi moyo wautali wa nyumba zomwe zimamangidwa pazigawo za maziko awa.
