Kowiri tira Paipa Tapawhā Tapawhā
Kowiri tira Tube Tapawha Ko tetahi ahua o nga putorino.He porowhita, he tapawha, he tapawha, he hexagonal me nga momo paipa waipēhi kei roto i nga momo kowiri tira.He 304, 316 nga tohu o te austenitic kowiri tira e whakamahia ana i roto i nga ahumahi.Arā ano etahi atu momo paipa kowiri tira penei i te taarua, te ferritic, te martensitic me te koranu maitai.
Kowiri tira ngongo tapawha me te ngongo tapawhā e kiia ana ko te ngongo maitai, ngongo hanganga ranei.Ka tohuhia ano enei hei waahanga hangahanga tuwhera he HSS ranei mo te poto.Ka whakamahia mo nga kaupapa hanganga, ngongo tapawha, ngongo tapawha, I kurupae, me etahi atu, ka taea te hoko i roto i nga momo momo rino me nga koranu.Ko te hanga ngongo tapawha he rite tonu ki te mahi hanga putorino engari ka haere te hua i roto i te raupapa o nga turanga hanga, ka tutuki i ona whakaritenga tapawha whakamutunga.
Ko te wahanga whiti tapawha o nga ngongo e whakarato ana i te kaha ahuahanga pai.Na reira ka whakamahia nga paipa ki nga tono kaha teitei.He pehanga teitei me nga ratonga pāmahana teitei penei i nga whakawhiti wera e whakamahi ana i nga paipa.Ko te ngongo tapawha 316 ss he kaha me te aukati i te waikura.Ko te rauemi 316 he chromium, nickel me te molybdenum i roto i te hanganga.Ko tenei huinga ka taea te whakanui ake i te parenga waikura me te 215MPa te iti o te kaha tuku 505MPa te kaha tensile iti.Ka taea hoki e nga ngongo te mahi i raro i te mahana ki te 870 nga nekehanga Celsius.Ko te SS Square Welded Tube kei te whakamahi i nga keehi i roto i te hinu me te hau, te hinu, te petrochemical, te hanga me nga tono hanganga hoki.He reanga teitei ake penei i te SS317 Square Tubes he mea hanga mai i te 317 rauemi karaehe he 517MPa te iti rawa o te kaha.He whai hua i roto i nga tono kaha kaha.Ko te ASTM A270 Seamless Square Tube e whakamahia ana i roto i te pehanga teitei, nga ratonga pāmahana teitei tae atu ki nga ratonga pirau whanui.
Kowiri tira ngongo tapawha tuikore, Te Tukanga Whakaputa
Whakaritea maitai a tawhio noa → whakawera → wera okeoke perforation → tapahi upoko → pickling → ororongo → whakahinuhinu → tukanga hurihuri matao → degreasing → maimoatanga wera otinga → whakatika → tapahi paipa → pickling → oti te tirotiro hua.
Kowiri tira ngongo tapawha tuitui ，Atatari Mahi
Ka taea e te konganuku te tauhohe ki te hāora i roto i te kōhauhau hei hanga i te kiriata waikura ki te mata.Ko te waikura rino i hangaia i runga i te waro waro noa ka whakahaora tonu, ka whakawhanui i te waikura, ka puta he kohao.Ka taea tenei ma te whakamahi peita, he whakakikorua whakarewa waiora-atete ranei hei tiaki i te mata o te waro maitai, engari he kiriata kikokore noa iho tenei paninga.Mena kua pakaru te paninga, ka timata te tira o raro ki te waikura ano.Ahakoa kua waikura te ngongo kowiri tira e pa ana ki te ihirangi chromium i roto i te maitai.Ka tae te ihirangi chromium i roto i te maitai ki te 12%, ka hangaia e te mata o te ngongo kowiri tira he paparanga o te passivation me te waikura nui o te chromium hei tiaki i te mata me te aukati i te reoxidation.He tino kikokore tenei paparanga waikura, ma reira e kitea ai te kanapa o te mata maitai, na te mea kowiri tira he mata ahurei.Ki te pakaru te kiriata chromium kotahi, te chromium i roto i te maitai me te hāora i roto i te kōhauhau ki te whakahou i te kiriata passivation, tonu ki te tākaro i te tūranga tiaki.I roto i etahi taiao motuhake, ka puta ano he kowiri tira etahi waikura o te rohe me te kore, engari he rereke te kowiri tira me te waro waro, kaore e puta te ahua o te waikura me te kore, na reira he koretake te utu waikura mo te ngongo kowiri tira.
