Chithunzi cha ASTM A320

Mbali
Povomerezedwa koyambirira mu 1948, mawonekedwe a ASTM A320 amakwirira zitsulo za aloyi ndi zitsulo zosapanga dzimbiri zopangira ntchito yotsika kutentha. Muyezo uwu umakwirira zitsulo zolimba, zopindika, zopindika, zomangira, zomangira, zomangira, ndi zomangira zomwe zimagwiritsidwa ntchito paziwiya zokakamiza, ma valve, ma flanges, ndi zolumikizira. Monga mafotokozedwe a ASTM A193, pokhapokha atanenedwa mwanjira ina, ulusi wa 8UN umatchulidwa pa chomangira chachikulu kuposa 1” m'mimba mwake.
Pansipa pali chidule chachidule cha magiredi ochepa omwe ali mkati mwa ASTM A320. Magiredi ena ochepa a ASTM A320 alipo, koma sanafotokozedwe mwatsatanetsatane pansipa.
