Tohu Hua

He aha te ASTM A179/ASME SA179?

ASTM A179 (ASME SA179) he ngongo rino tuitui iti te waro makariri mo te whakamahi i roto i nga whakawhiti wera tubular, condenser, me nga tono whakawhiti wera rite.

Ko te ASTM A179 me te ASME SA179 e rua nga paerewa e tino rite ana.Mo te pai, ka whakamahia te ASTM A179 i raro nei.

Awhe Ahu

He pai te ASTM A179 mo nga paipa maitai me te diameter o waho o te 1/8″ – 3″ [3.2mm - 76.2mm].

Te maitai o rungahe putorino paipa paipa tuitui mai i Haina, e tuku ana ki a koe he kowhiringa nui o nga paipa maitai tuitui paipa mo te ASTM A179/ASME SA179.

E whakatapua ana matou ki te whakarato ki o taatau kaihoko nga hua me nga ratonga o te kounga teitei kia pai ai te rere o o kaupapa.Kōwhiri Botop Steel, ka whiriwhiri i te hoa pono.

Tukanga Hangahanga

Kua korerohia e matou ko te A179 ka hangaia ma te whakamahi i nga mahi hangahanga kore-matao.He aha nga tukanga motuhake e uru ana ki te hanga maeke korekore?Tirohia te tūtohi rerenga tukanga e whai ake nei.

Ko te tukanga whakangao putorino maitai kore-mao

I roto i te paerewa ASTM,A556ka whakamahi hoki i te tukanga whakangao kore-matao engari he mea motuhake mo nga whakamahana wai tubular.Ka taea e te hunga e hiahia ana ki te mohio atu.

Maimoatanga Wera

I muri i te tuhi matao whakamutunga, ka whakamahana nga ngongo maitai ki te mahana o te 1200°F [650°C] teitei ake ranei.

Whakamātautau Hydrostatic

Ko ia putorino ka tukuna ki te whakamatautau pehanga waipēhi, ki te whakatauhia e te kaihoko, ka whakamahia he whakamatautau hiko kore-whakangaro.

Ko te ngongo maitai e pupuri ana i te pehanga mo te iti rawa 5s me te kore e turuturu.

Ka tatauhia te pehanga whakamatautau ma te whakamahi i te tauira e whai ake nei:

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.

Taapiri mo te ASTM A179

Ko nga mea e whai ake nei ko te kohinga A179 noa, ka taea hoki te whakarato i nga kohinga taapiri kia rite ki nga whakaritenga kaupapa.

Pupa kore, paninga pango ( whakaritea);
