A106B A210A1 A210C / Carbon Steel Paipa Tukore
Tikanga tirotiro kounga o te paipa maitai kore
1. Te tātari hanganga matū: tikanga tātari matū, tātari taputapu (taputapu CS infrared, spectrometer panui tika, zcP, etc.).
① He taputapu CS Infrared: he tātaritanga o te ferroalloy, te hanga maitai, nga huānga C, S i roto i te maitai.
② Irirangi panui tika: C, Si, Mn, P, S, Cr, Mo, Ni, Cn, A1, W, V, Ti, B, Nb, As, Sn, Sb, Pb, Bi i roto i nga tauira poraka
③ N- -0 taputapu: tātari ihirangi hau N me O.
2. Te tirotiro kounga mata o te paipa maitai: 100%
① Te tirotiro a-ringa: nga tikanga rama, nga paerewa, te wheako, te tautuhi, te hurihanga paipa maitai.
② Tirohanga NDT:
A. Tirohanga Ultrasonic UT:
B. ET: (urukuhiko hiko)
C. MT me te kitenga turuturu:
Te kitenga koha aukume, e tika ana mo te kite i nga koha o te mata me te tata-mata o nga rawa ferromagnetic.
D. Te kitenga koha ultrasonic hiko:
Kaore e hiahiatia he reo hono, ka taea te whakamahi ki te teitei o te wera me te tere tere, te taratara me te maroke o te paipa rino e kitea ana koha.
E. whakamātautau uru wai:
Te whiti, te tae, me te kite i nga hapa o te mata paipa maitai.
3. Te tirotiro mahi tinana me te matū o te paipa maitai:
① Whakamātautau tensile: ine i te ahotea me te deformation, whakatau i te kaha o te rauemi (YS, TS) me te taupū kirihou (A, Z)
Te roa, te wahanga whakawhiti, te pewa, te porohita (￠ 10, ￠ 12.5)
Te diameter iti, te pakitara angiangi, te diameter nui, te tawhiti whakatikatika i te pakitara.
② Whakamātautau pānga: CVN, kakari C, V, mahi J uara J / cm2
Tauira paerewa 101055 (mm) Tauira kore-paerewa 55 5 (mm)
③ Whakamātautau pakeke: Brinell pakeke HB, Rockell pakeke HRC, Vickers pakeke HV, etc
④ Whakamatau Hydraulic: te pehanga whakamatautau, te wa whakapumau, p=2S δ / D
4. Tukatuka mahi tirotiro o te paipa maitai:
① Whakamātautau papatahi: tauira porowhita tauira C-āhua (S / D & gt; 0.15) H= (1 + 2) S / (+ S / D)
L=40~100mm mo ia waeine roa whakareatanga deformation =0.07~0.08
② Whakamātautau kumea: L=15mm te kore kapiti he tohu
③ Te whakawhanui me te whakamatautau koiri: ko te 30°, 40° me te 60° te tihi o runga.
④ Whakamatau piko: ka taea te whakakapi i te whakamatautau whakapati (mo te paipa diameter nui).
