ngongo maitai tuitui mo te Heat exchanger / Boiler pipe
Whakaaturanga hua
Ko te whakamaroke (te whakamaroke, e mohiotia ana ko te tinei) -ko te ngongo kohua teitei te whakamahana kia rite ki te pāmahana e tika ana, katahi ka rukuhia ki te wai, ki te hinu ranei i roto i te whakamahana tere, i te hau, i te waahi mīti ranei, kia whakamataohia te kohua teitei. ngongo ki te whiwhi i te pakeke e hiahiatia ana.
Ka pakarukaru te putorino kohu pehanga-teitei i muri i te tinei.I te wa ano, ko te ahotea na te tineia me te whakamatao ka pakaru te putorino paoho teitei ma te pupuhi marama.Hei whakakore i te pakaruhanga, ka taea te whakamahi i te tikanga maimoatanga whakamarumaru.Ko te whakamahana he whakamahana i te ngongo kohua teitei ki te pāmahana e tika ana, te tae ranei, katahi ka hoatu te makariri nui.Ahakoa he paku iti te pakeke o te putorino kohu pehanga teitei, ka taea e ia te whakanui ake i te uaua o te putorino kohua teitei me te whakaiti i tona pakaruhanga.
Ko te whakaene-annealing te tikanga ki te whakakore i te ahotea o roto me te maitai o te putorino kohua teitei.Ko te tikanga whakamahana ko te whakamahana i nga wahanga rino ki te wera nui, katahi ka maka ki roto ki te pungarehu maroke, kotakota, asbestos, katia ranei ki roto i te oumu, kia ata whakamatao.
Maamaa (Mardness) -ko te kaha o tetahi mea ki te aukati i te kuhu o waho.He tino tika te whakamatautau pakeke, he tikanga noa hei whakamatautau i te pakeke.Ko te tikanga whakamatautau e whakamahia nuitia ana ko te Rockwell hardness test Ka whakamahia e te miihini whakamatautau pakeke Rockwell te hohonutanga o te taimana i rere ki roto i te whakarewa ki te whakatau i te pakeke o te putorino kōhua teitei, te nui o te hohonu o te kuhu, te iti ake o te pakeke.Ka tere te taimana ki te hohonutanga o te whakarewa hei tohu i te tau tika mai i te atatohu, e kiia nei ko te tau pakeke Rockwell.
Forging-ko te hama hei hanga i te whakarewa ki tetahi ahua & lt;niao & gt;tikanga, i te wa e whakawerahia ana te ngongo kōhua pehanga teitei ki te pāmahana whakahiato, ka taea te mahi ki te hangai, ki te piko, ki te tuhi, ki te hanga me etahi atu mahi.Ko te nuinga o nga ngongo kohua teitei he ngawari ki te hanga ina whakamahana ki te whero here kanapa.
Britittleness-e tohu ana i te ahua o te putorino kohua teitei he ngawari ki te pakaru, he pakarukaru te rino maka, ka taka ki te whenua ka pakaru.He tata te hononga o te Britittleness me te pakeke, te pakeke o te 20 # putorino maitai te tikanga he pakarukaru hoki.
ductility- (e mohiotia ana ano ko te ngawari) ko te ahua o te whakarewatanga mau tonu na te kaha o waho me te kore he wehenga, ka taea te kumea te paipa o te putorino pehanga teitei ki nga raina kikokore.
Elastic-he taonga o te ngongo kohu pehanga teitei kua whakahekehia e te kaha o waho, ka whakakorehia te kaha o waho.Ko te maitai o te puna he mea tino rapa.
Ko te pakeke-ko te aukati whakarewa ki te werohanga o waho, ki te tapahi ranei ka taea te whakanui ake i te pehanga teitei o te kohuatanga ngongo pakeke ko te tinei tikanga.
Mahinga- -e mohiotia ana ko te malleability, he tohu ano mo te ngawari me te ngawari.Ko te whakaaturanga he taonga mo te whakarewa i te hama te hanga, te huri ranei.
Ko te uaua ko te kaha o te putorino kohua teitei ki te tu ki te wiri, ki te paahitanga ranei.Ko te uaua he rereke noa iho o te pakarukaru.
I roto i te tukanga whakaputa o te putorino maitai mo te kōhua, maimoatanga wera ko te tukanga matua.Ko te maimoatanga wera he paanga nui ki te kounga o roto me te kounga o te mata o te putorino maitai kore, he mea tino nui mo te hanga o te putorino koranu maitai.
Ka whakamahia e to taatau kamupene te maimoatanga wera kore-haora, te hanga paipa rino me te whakahaere metallographic pumau me te pai o te kounga o roto, o waho hoki, ma te whakamahi i te eddy o naianei me te ultrasonic aunoa i te rapu koha, te paipa rino tetahi mo te koha o naianei eddy me te koha ultrasonic.Ma te inenga matotoru ultrasonic me nga mahi whakakitenga koha, ka taea e ia te kite i nga hapa o te paparanga i roto i te paipa maitai.
