13CrMo4-5 ND Alloy Steel Seamless Pipe
09CrCuSb(ND) ngongo maitai tuitui mo te aukati waikawa pungatara, iti te wera o te tomairangi me te waikura.
Ko te maitai ND he momo hou o te rino hanganga koranu iti, ka whakatauritea ki etahi atu maitai, penei i te rino waro-iti, Corten, CRIA, ND maitai te painga o te pai o te aukati waikura me nga taonga miihini.I kitea e nga hua whakamatautau he teitei ake te parenga waikura o te rino ND i roto i te wairewa wai penei i te waikawa pungatara, te waikawa pūhaumāota me te konutai pūhaumāota i te waro maitai.Ko te mea tino nui ko te kaha o te waikawa sulfuric dew point corrosion resistance;he teitei ake te taonga miihini me te pumau atu i te maitai waro mai i te pāmahana rūma ki te 500 C, a he pai te mahi whakahiato.ND maitai whakamahia tonu mo te hanga ohaoha, whakawhiti wera, hau i mua i te whakamahana, mai i te 1990, kua whakamahia te maitai ND i roto i te umanga o te petrifaction me te hiko.

ngongo maitai tuitui mo te Heat exchanger / Boiler pipe
Whakaaturanga hua:
Heat Treatment-He tikanga e whakamahi ana i te whakamahana me te whakamatao ki te huri i nga ahuatanga o te tinana o nga putorino kohua teitei.Ka taea e te maimoatanga wera te whakapai ake i te microstructure o te ngongo kohua teitei, kia tutuki ai nga whakaritenga a-tinana e hiahiatia ana.Ko te uaua, te pakeke, me te whakakakahu he maha o nga taonga ka riro mai i te maimoatanga wera.Ki te whiwhi i enei ahuatanga, whakamahia te tiini & lt i te maimoatanga wera;ka karanga hoki tinei & gt;, tempering, annealing & lt;rewa & gt;me te whakapakeke o te mata, etc.

T11 T12 T22 T91 T92 Alloy Steel Seamless Pipe
Whakaaturanga hua:
Ko te putorino maitai tuitui he momo putorino maitai, he nui ake te mahi i te putorino maitai whanui, na te mea kei roto i tenei momo putorino maitai te whakatairite Cr.
He maha, ko te kaha o te pāmahana teitei, te iti o te pāmahana, te mahi aukati waikura e kore e rite ki etahi atu putorino maitai, na reira ka whakamahia nuitia te paipa koranu i roto i te hinu, te ahumahi matū, te hiko hiko, te kohua me etahi atu ahumahi.
Ko te putorino maitai o te Alloy he mea hanga penei i te silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, konumohe, parahi, boron, whenua onge me era atu.

A106B A210A1 A210C / Carbon Steel Paipa Tukore
Whakaaturanga hua:
Ko te paipa kohu he momo paipa kore.Ko te tikanga hanga he rite tonu ki te paipa kore, engari he tino whakaritenga mo te momo maitai e whakamahia ana mo te hanga i te paipa maitai.
Ko nga taonga miihini o te paipa kohua he tohu nui hei whakarite i te mahi ratonga whakamutunga (nga taonga miihini) o te maitai, e whakawhirinaki ana ki te hanganga matū me te punaha maimoatanga wera o te maitai.I roto i te paerewa paipa maitai, kia rite ki nga whakaritenga whakamahinga rereke, ko te mahi tensile (te kaha o te kaha, te kaha o te tuku, te tohu hua ranei, te elongation), me nga tohu pakeke me te pakari, me te mahi teitei me te iti o te pāmahana e hiahiatia ana e nga kaiwhakamahi.
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.
