ASTM A302 Kōeke A Mn-Mo Alloy Pressure Vessel Steel Plate

A302 Koeke A pereti rino te tohu paerewa mo nga pereti oko pehanga i roto i te rino koranu, konupora molybdenum me te konupora-molybdenum-nickel. A302 Koeke A me pereti rino te tikanga ka tukuna i roto i te ahua o te hurihuri. Ka tonohia nga pereti kia rite, kia marie ranei te ahotea, e rua ranei. Mena he A 302 Koeke A kei runga ake i te 50mm te matotoru ka whakatauhia.
ASTM A302 Kōeke A Mn-Mo Alloy Pressure Vessel Steel Plate Whakaahuatanga:
Kei roto i tenei whakakitenga nga pereti rino konupora-molybdenum me te konupora-molybdenum-nickel i whakaritea mo nga kohua paiherea me etahi atu oko pehanga. Ko te ASTM A302 he momo whakahiato rino koranu iti e kapi ana i nga reanga rereke e 4 (A, B, C, D), Ko te Koeke C me te D kei roto te hanganga matū Ni, he rite te matotoru, te tuku me te kaha o te Koeke C he rite ki te Koeke. B, i te mea he teitei ake te reeti whakaroa o te karaehe C. Ko tenei tohu e kapi ana i nga pereti rino konupora-molybdenum me te konupora-molybdenum-nickel te koranu rino e tika ana mo nga kohua paiherea me etahi atu oko pehanga. Ko te ASTM A302 he momo whakahiato rino koranu iti e hipoki ana i nga tohu rereke e 4 (A, B, C, D), Ko te Koeke C me D kei roto i te hanganga matū Ni, he rite te matotoru, te tuku me te kaha o te Tohu C he rite tonu ki te Tohu. B, i te mea he teitei ake te reiti whakaroa o te kōeke C. He mea hanga mo te Puka Peehanga, Te Kohua, Nga Tanks Rokiroki me te Whakawhiti wera i roto i te Hinu, Kaupapa Hau.
