ASTM Standards yeCarbon Steel Pipe
Sangano reAmerican Society for Testing and Materials (ASTM) rakagadzira mitemo yakasiyana-siyana yemapombi esimbi yekabhoni, iyo inotsanangura zvakadzama saizi, chimiro, kuumbwa kwemakemikari, hunhu hwemakanika nezvimwe zvinodiwa zvehunyanzvi zvemapombi esimbi. Izvi zvinotevera zviyero zvakati wandei zveASTM zvemapombi esimbi yekabhoni:
1. Mapaipi eSimbi yeKabhoni Isina Musono
ASTM A53: Inoshanda kune simbi dzakasungirirwa uye dzisina musono uye nhemamapaipi esimbi anopisa-kunyika, inoshandiswa zvakanyanya pakuvaka, masisitimu emapaipi, nezvimwewo. Mutemo uyu wakakamurwa kuita magiredhi matatu: A, B, naC zvichienderana nekukora kwemadziro.
ASTM A106: Mapaipi esimbi yekabhoni asina musono akakodzera kushandiswa pakupisa kwakanyanya, akakamurwa kuita Giredhi A, B, naC, anonyanya kushandiswa mumapaipi emafuta, ekufambisa gasi rechisikigo uye maindasitiri emakemikari.
ASTM A519: Inoshanda pamabhawa nemapaipi esimbi yekabhoni isina musono pakugadzika, ine zvinodiwa zvakasimba zvekushivirira mativi.
2. Mapaipi eSimbi yeKabhoni Yakasungirirwa
ASTM A500: Inoshanda kune simbi dzakasungirirwa dzakagadzirwa nechando uye dzisina musono,rectangularuye mamwe mapaipi esimbi ane chimiro chakafanana, anoshandiswa zvakanyanya muzvivakwa.
ASTM A501: Inoshanda pamapombi esimbi akasungirirwa nemoto uye asina musono, akaenzana uye mamwe mapombi esimbi ane chimiro chakafanana.
ASTM A513: Inoshanda pamagetsimapaipi esimbi akatenderera akasungirirwa, inowanzoshandiswa pakugadzira michina uye mashandisirwo ekuvaka.
3. Mapaipi esimbi yekabhoni emabhaira nema superheaters
ASTM A179: Inoshanda pamapombi ebhoyira esimbi inodhonzwa nechando, yakakodzera kushandiswa kwemhepo ine simba rakawanda.
ASTM A210: Inoshanda pamapombi ebhaira esimbi yekabhoni isina musono, akakamurwa kuita magiredhi mana: A1, A1P, A2, uye A2P, anonyanya kushandiswa kumabhoira ane simba repakati nepasi.
ASTM A335: Inoshanda kumapaipi esimbi yeferritic alloy isina musono, akakamurwa kuita magiredhi akasiyana-siyana, akadai seP1, P5, nezvimwewo, yakakodzera mapaipi ekupisa kwakanyanya mumaindasitiri epetrochemical nemagetsi.
4. Mapaipi esimbi yekabhoni ekushandisa mafuta negasi
ASTM A252: Inoshanda kune arc inotenderera ine musono wakadzikamapaipi esimbi akasungirirwayemapombi, anoshandiswa zvakanyanya mukuvaka mapuratifomu ari kunze kwegungwa.
ASTM A506: Inoshanda pamapaipi esimbi ane simba rakawanda, akakodzera kugadzirwa kwemidziyo yemafuta negasi.
ASTM A672: Inoshanda pamapombi esimbi esimbi ecarbon manganese silicon ane simba guru, yakakodzera kushandiswa kunoda simba rakawanda.
API Spec 5L: Kunyangwe isiri mwero weASTM, imhando inogamuchirwa pasi rose yemapombi esimbi emapombi emafuta negasi, iyo inofukidza mhando dzakawanda dzemapombi esimbi yekabhoni.
5. Mapaipi esimbi yekabhoni ezvinangwa zvakakosha
ASTM A312: Inoshanda kumapaipi esimbi isina musono uye akasungirirwa. Kunyangwe ichinyanya kushandiswa pasimbi isina musono, inewo mamwe magadzirirwo esimbi yekabhoni.
ASTM A795: Inoshanda kune simbi yekabhoni uye alloy steel billets, denderedzwa billets uye zvigadzirwa zvavo zvakagadzirwa ne continuous casting and forging, yakakodzera kuminda chaiyo yeindasitiri.
Maitiro ekusarudza chiyero chakakodzera cheASTM
Kusarudza chiyero chakakodzera cheASTM zvinoenderana nezvinodiwa zvekushandisa:
Nzvimbo yekushandisa: Funga nezvezvinhu zvakaita sekupisa kwekushanda, mamiriro ekumanikidzwa, uye kuvapo kwemidziyo inoparadza.
Hunhu hwemakanika: Sarudza simba remubereko unodiwa, simba rekudhonza uye zvimwe zviratidzo zvikuru.
Kururama kwehukuru: Kune mamwe mashandisirwo ekugadzira kana kugadzira nemazvo, dhayamita yekunze uye ukobvu hwemadziro zvinotarisirwa zvakanyanya.
Kurapa pamusoro: Kungave kushandisa galvanizing inopisa, kupenda kana dzimwe nzira dzekudzivirira ngura zvinodiwa.
