Kana zvasvika pakuvaka nekugadzira mainjiniya, kusarudza zvinhu zvakakosha pakuona kuti chivakwa chacho chakasimba uye chicharamba chiripo kwenguva refu. Chimwe chezvinhu zvakadaro chakawana mukurumbira wakasimba muindasitiri iyi ndecheASTM A252 Giredhi 2Mapombi eMapombi. Blog rino richaongorora zvakadzama zvinodiwa, hunhu, uye zvinodiwa pakumaka zveASTM A252 Giredhi 2 kuti rinzwisise kukosha kwayo mumapurojekiti ekuvaka.
Chii chinonzi ASTM A252 Giredhi 2?
ASTM A252 ndiyo nzira yakatarwa yekuisa mapombi esimbi akasungirirwa uye asina musono ekushandisa panheyo. Giredhi 2 ndeimwe yemapombi matatu akatsanangurwa muchiyero ichi, Giredhi 1 riri rakaderera uye Giredhi 3 riri rakakwirira maererano nesimba rekugadzira. Mapombi emapambi eASTM A252 Giredhi 2 akagadzirwa kuti ape simba rakaringana uye ductility, zvichiita kuti akwanise kushandiswa kwakasiyana-siyana, kusanganisira nheyo dzakadzika, zvivakwa zvegungwa, nezvimwe zviitiko zvinotakura mutoro.
Hunhu hukuru hweASTM A252 Giredhi 2 hunosanganisira simba rekukura re35,000 psi uye simba rekudhonza re60,000 psi. Hunhu uhwu hunovimbisa kuti mapombi anogona kutsungirira mitoro yakakura uye kumanikidzwa, zvichiita kuti ave akakodzera kushandiswa munzvimbo dzakaoma.
Zvinodiwa pakuisa chiratidzo chemapaipi eASTM A252 Giredhi 2
Chinhu chakakosha pamapango eASTM A252 Giredhi 2 kudiwa kwekumaka nemazvo. Pango rega rega rinofanira kunge rakaiswa chiratidzo chakajeka kuti ripe ruzivo rwakakosha nezvechigadzirwa. Chiratidzo ichi chakakosha kuti chionekwe zvakanaka, chive nechokwadi chemhando, uye chitevedzere mitemo yeindasitiri. Zvinotevera zvinofanira kuiswa muchiratidzo ichi:
1. Zita remugadziri kana kuti rudzi: Izvi zvinoratidza mugadziri wemurwi, zvichiita kuti mushandisi akwanise kutsvaga chigadzirwa kubva kwachiri.
2. Nhamba yekupisa: Nhamba yekupisa chiratidzo chakasiyana chinopihwa kune imwe simbi. Inobvumira mavambo uye hunhu hwechinhu chacho kuteverwa, izvo zvakakosha pakudzora hunhu.
3. Maitiro eMugadziri: Izvi zvinoratidza nzira inoshandiswa kugadzira murwi, ingave yakasungirirwa kana isina musono. Kunzwisisa maitiro ekugadzira kunobatsira pakuongorora mashandiro emurwi.
4. Rudzi rweSpiral Joint: Rudzi rweSpiral Joint rinoshandiswa mumurwi wepombiinofanira kunge yakanyorwa, kana zvichibvira. Ruzivo urwu rwakakosha pakunzwisisa kusimba kwechimiro chemurwi.
5. Dhayamita Yekunze: Dhayamita yekunze yemurwi inofanira kunyorwa zvakajeka sezvo iri chiyero chakakosha pakuisa uye kuverenga mutoro.
6. Ukobvu hwemadziro: Ukobvu hwemadziro emurwi chimwe chinhu chakakosha chinokanganisa simba rayo uye kugona kwayo kutakura.
7. Kureba nehuremu pahurefu: Hurefu hwese nehuremu pahurefu hwemurwi hunofanira kutaurwa. Ruzivo urwu rwakakosha pakuronga zvekufambisa zvinhu uye kuisa.
8. Zita reChinyorwa neGiredhi: Chekupedzisira, chiratidzo chinofanira kusanganisira zita reChinyorwa (ASTM A252) neGiredhi (Giredhi 2) kuti zvive nechokwadi chekutevedzera mitemo yeindasitiri.
Mukupedzisa
Mapombi eASTM A252 Giredhi 2 akakosha pakuvaka kwemazuva ano, zvichipa simba rinodiwa uye kugara kwenguva refu kune akasiyana mashandisirwo. Kunzwisisa zvinodiwa zvemagadzirirwo uye mamaki kwakakosha kune mainjiniya, makondirakiti, uye vatariri vemapurojekiti kuti vave nechokwadi chekuti vari kushandisa zvinhu zvakakodzera kumapurojekiti avo. Nekutevedzera mitemo iyi, indasitiri yekuvaka inogona kuchengetedza tsika dzemhando yepamusoro uye kuona kuchengetedzeka uye kugara kwenguva refu kwezvivakwa zvakavakirwa panheyo idzi.
