Tohu Hua

He aha te ASTM A192/ASME SA192?

ASTM A192 (ASME SA192) Ko te paipa maitai he putorino waro waro paipa e whakamahia ana i roto i nga taiao teitei me te pehanga teitei, ka whakamahia nuitia i roto i nga kohua me nga whakawhiti wera.

ASTM A192 Awhe Ahua

Te diameter o waho: 1/2″ – 7″ (12.7 mm – 177.8 mm);

Te matotoru o te pakitara: 0.085″ – 1.000″ (2.2 mm – 25.4 mm);

Ko etahi atu rahi o te paipa rino ka taea hoki te tuku ina hiahiatia, mena ka tutuki nga whakaritenga katoa o A192.

Tukanga Hangahanga

Ko te ASTM A192 he mea hanga ma te whakamahi i te tukanga tuitui, ka oti te wera, te makariri ranei i te mea e hiahiatia ana;

Ano hoki, me whakaatu te tohu paipa rino mehemea he wera te paipa maitai, he makariri ranei.

tukanga paipa- maitai-kore

Whakaoti wera: E tohu ana ki te tukanga whakaoti i nga rahinga whakamutunga o te ngongo maitai i roto i te ahua wera.I muri i te ngongo maitai kua tukuna he tukanga tukatuka wera penei i te hurihuri wera, te tuhi wera ranei, kaore i te tukatuka atu i te makariri.He pai ake te pakari me te ngawari o nga ngongo rino kua oti te wera, engari he nui ake te ahua.

Kua mutu te makariri: Ka tukatukahia te paipa maitai ki ona rahinga whakamutunga ma nga mahi mahi makariri penei i te hurihuri makariri, te tuhi matao ranei i te pāmahana rūma.Ko nga paipa rino kua oti te makariri he pai ake te ahua o te ahua me nga papa maeneene engari ka mate pea te uaua.

Maimoatanga Wera

Ko nga ngongo rino korekore kua oti te wera kaore e hiahiatia he maimoatanga wera.

Ko nga ngongo rino tuitui kua oti te makariri ka whakamahana ki te wera ki te 1200°F [650°C] teitei ake ranei i muri i te maimoatanga makariri whakamutunga.

ASTM A192 te pakeke

 

Rockwell Hardness: 77HRBW.

Mo nga paipa maitai he iti iho te matotoru o te pakitara i te 0.2" [5.1 mm].

Brinell pakeke: 137HBW.

Mo te paipa rino te matotoru o te pakitara 0.2" [5.1 mm] neke atu ranei.

Mo nga whakaritenga whakahaere motuhake, tirohia te ASTM A450, Te nama take 23.

ASTM A192 whakamatautau pakeke

Whakamātautau Hydrostatic

· Auautanga: Ko ia putorino maitai ka tukuna ki te whakamatautau pehanga wai.

· Wā: Kia mau te pēhanga iti rawa kia 5 hēkona.

· Uara pehanga wai: Ka tatauhia ma te whakamahi i te tauira e whai ake nei.Tuhia te waeine.

Inihi - Wae Pauna: P = 32000 t/D
Waeine SI: P = 220.6t/D

P = te pēhanga whakamātautau hydrostatic, psi, MPa ranei;

t = te matotoru pakitara kua tohua, in., mm ranei;

D = kua tohua te diameter o waho, in., mm ranei.

· Te Hua: Mena karekau he rerenga o nga paipa, ka kiia kua paahitia te whakamatautau.

Ka taea ano te rereke ki te whakamatautau hydrostatic me nga whakamatautau kore-whakangaro.

Heoi, kaore te paerewa e kii ko tehea tikanga whakamatautau kore-kino ka taea te whakamahi.

Nga Mahi Hanga

Ko nga ngongo ka kuhu ki roto i te kohu ka noho whanui me te pirepire me te kore e kitea he kapiti, he koha ranei.Ko nga ngongo whakawera i te wa e whakahaerea tikatia ana ka tu katoa nga mahi hangai, whakapiringa me nga mahi piko e tika ana mo te tono me te kore e puta he hapa.

Mo matou
