ASTM A333Gr6/ASME SA333Gr6 Paipi yesimbi yakaderera tembiricha
zvigadzirwa zvinodiwa
Giredhi: A333Gr.6 / SA333Gr.6
Standard: ASTM A333 / ASME SA333
simbi pombi kugadzira muitiro
Kugadzirwa kwepombi dzesimbi kunoitwa maererano neiyo tekinoroji system ye20G simbi.
Simbi pombi dimensional kutsauka uye uremu kutsauka

Yakagadziriswa-kureba kurongeka: zvinoenderana nezvinodiwa nemushandisi.
Kutwasanuka: ≤1.5mm / m.
Delivery mamiriro uye kupisa kurapwa muitiro wesimbi pombi
Iyo pombi yesimbi inounzwa mune yakajairika kupisa kurapwa mamiriro.
Iyo yakajairika kupisa kupisa maitiro echigadzirwa chakapedzwa ndeye: 900 ° C ~ 930 ° C ye5 ~ 15min, kutonhora kwemhepo.
Mechanical properties yemapombi esimbi
Tensile properties
Iyo tensile zvimiro zvepombi dzesimbi zvinosangana nezvinodiwa zveASTM A333Gr6.
Pamapombi esimbi ane ukobvu hwezita remadziro ≤ 8mm, nhanho yekuedza tambo ndeye longitudinal strip test muenzaniso ine hupamhi hwe12.5mm uye geji chinhambwe che50mm. Pamapombi esimbi ane durawall gobvu ≥8mm, muenzaniso weraundi une geji chinhambwe che4D unogona kushandiswa.
Flattening bvunzo
Iyo yekupwanya chinhu ndeye 0.07.
Impact performance
Batch rimwe nerimwe remapombi esimbi ane dhayamita rekunze rakakura kupfuura 21.3mm richaongororwa kuti rine mabatiro anoita Akv.

Impact test tembiricha
Kana ukobvu hweiyo diki-saizi yekukanganisa inosvika kana kudarika 80% yehukobvu chaihwo hwepombi yesimbi, tembiricha yekuyedza i -45 ° C.
Kana ukobvu hweiyo diki-saizi yekukanganisa specimen iri pasi pe80% yehukobvu chaihwo hwepombi yesimbi, iyo yemuenzaniso ukobvu hunofanira kunge hwakakura sezvinobvira. Tembiricha yekuyedza yaive -55 ° C.
Kuomarara bvunzo (chete kana ichidikanwa nechibvumirano)
Kana kontrakiti ichida kuomarara kuedzwa zvinoenderana neNACE MR-0175 yakajairwa, chidimbu chekuyedza chinosvika 20-30 mm pakureba chinotorwa kubva pabhechi rega rega remapombi esimbi, uye kuomarara kunenge kuri pasi pe22HRc.
