Ruzivo rwemapaipi esimbi akasungirirwa eASTM A252
ASTM A252 imhando yakajairwa yemapombi esimbi akasungirirwa uye asina musono. Inosanganisira ukobvu hwemadziro, giredhi, uye rudzi rwesimbi.
Mapombi esimbi anogona kusungirirwa kana kusabatanidzwa uye anowanikwa muhupamhi hwakasiyana-siyana uye ukobvu hwemadziro kuti akwane zvinodiwa zvakasiyana-siyana zvinotakura mutoro. Anowanzo shandiswa mumapurojekiti ekuvaka uko mamiriro evhu anoda rutsigiro rwakadzika rwenheyo, senge munzvimbo dzemahombekombe, mahombekombe enzizi, kana nzvimbo dzine ivhu rakapfava kana rakasununguka.
