Te Tirotiro o te Paipa ASTM A106/ASME SA106

Ko te ASTM A106/ASME SA106 te paerewa mō ngā paipa maitai waro kore-hono e whakamahia ana mō ngā ratonga pāmahana teitei. E toru ngā taumata A, B me C, ā, ko te taumata whakamahinga noa ko te A106 Taumata B. E whakamahia ana i roto i ngā ahumahi rerekē, ehara i te mea mō ngā pūnaha paipa pēnei i te hinu me te hau, te wai, te tuku para kohuke, engari mō ngā kaupapa poiha, te hanga, me ngā hanganga anō hoki.

Te hanganga matū i roto i te %

● Waro (C) Teitei Mō te Taumata A 0.25, Mō te Taumata B 0.30, Taumata C 0.35
● Manganēhi (Mn): 0.27-0.93, 0.29-1.06
● Teitei o te Whānariki (S): ≤ 0.035
● Whero (P) : ≤ 0.035
● Silicon (Si) Min : ≥0.10
● Konukōre (Kr): ≤ 0.40
● Parahi (Cu): ≤ 0.40
● Molibdenum (Mo): ≤ 0.15
● Nikara (Ni): ≤ 0.40
● Vanadium (V): ≤ 0.08

Kia mōhio mai:
Mō ia whakahekenga o te 0.01% mō te huānga waro mōrahi, ka whakaaetia he pikinga o te 0.06% konupora ki runga ake i te uara kua tohua, ā, tae atu ki te mōrahi o te 1.35%.
Kaua ngā huānga Cr, Cu, Mo, Ni, V e neke ake i te 1%.

ASTM A106 Kaha B Kaha Kume me te Kaha Tuku

Tātai whakaroa:
I roto i te 2 inihi [50mm], me tatau mā te: e = 625 000 A^0.2 / U^0.9
Mō ngā waeine inihi-pauna, e = 1940 A^0.2 / U^0.9
Kei konei ngā whakamārama mō e, A, me U. (He rite te whārite ki te ASTM A53, paipa API 5L.)
Kaha Kume, iti rawa, psi [MPa] Tau A 48,000 [330], Tau B 60,000 [415], Tau C 70,000 [485]
Te iti rawa o te kaha hua i te psi [MPa] Tau A 30,000 [205], B 35,000 [240], C 40,000 [275]
Te toronga i roto i te 2 inihi (50mm), ōrau iti rawa %
Mō ngā rahi iti katoa i whakamatautauria i te wāhanga katoa, ko ngā whakamātautau toronga whakawhiti iti rawa taketake: Tau A Roa 35, Whakawhiti 25; B 30, 16.5; C 30, 16.5;
Mēnā ka whakamahia he tauira whakamātautau porowhita paerewa 2 inihi te roa, ko ngā uara o runga ake nei: Tau A 28, 20; B 22, 12; C 20, 12.

Kaupapa Ahumahi Paipa ASTM A106 Taumata B

E kapi ana te paerewa i ngā rahi paipa i roto i te NPS (Motu Paerewa Tika) mai i te 1/8 inihi ki te 48 inihi (10.3mm DN6 – 1219mm DN1200), i te wā kotahi, e tutuki ana te matotoru pakitara ingoa o te paerewa ASME B 36.10M. Mō ētahi atu rahi i waho o te ASME B 36.10M, e whakaaetia ana hoki te whakamahi i tēnei whakatakotoranga paerewa.

Ngā rauemi mata

Ko ngā rauemi e whakamahia ana mō te whakatakotoranga paerewa ASTM A106 me whai pānga ki te piko, ki te whakapiko, ki ngā tukanga hanga rite rānei. Mēnā ka whakarewahia te rauemi maitai, me tika te tukanga whakarewa mō tēnei taumata o ASTM A106, ā, me whai pānga hoki ki te taiao mahi pāmahana teitei.

Mēnā he paipa maitai ASTM A106 te kounga teitei ake, he pai ake rānei te kounga e hiahiatia ana, he whakaritenga kōwhiringa kei roto i te paerewa mō ngā whakaritenga tāpiri, mō ngā paipa i whakamahi i tēnei paerewa. Hei tāpiri, i roto i ēnei whakaritenga tāpiri i tonoa he whakamātautau tāpiri, ina tukuna te ota.
