X60 Raina Paipa, Tikanga Miihini O

X60 Raina Paipa, Ka wehea te maimoatanga wera o te Mata ki nga waahanga e rua, ko tetahi ko te maimoatanga wera matū, ko tetahi ko te tiini mata me te whakamaarama i te wera wera, ko te tikanga whakamatautau pakeke e whai ake nei:

[1] Te maimoatanga wera matū o te paipa X60
-- Ko te maimoatanga wera matū ko te whakauru i te mata o te ngongo paipa X60 ki roto i tetahi ngota huānga matū maha ranei, kia huri ai te hanganga matū, te hanganga me nga ahuatanga o te mata ngongo paipa X60.I muri tinei me te iti pāmahana tempering, te mata o X60 paipa paipa he pakeke tiketike, mau ātete me te kaha rohirohi whakapā, me te matua o X60 paipa paipa he kaha nui me te uaua.

-- Ko nga tawhā hangarau matua o te maimoatanga wera matū X60 pipeline ko te hohonu o te paparanga whakapakeke me te pakeke o te mata.Ko te hohonu o te paparanga whakapakeke me whakamatau e te Vickers hardness tester.Inehia te tawhiti mai i te mata paipa X60 ki te waahi ka heke te pakeke ki te 50HRC.Ko te hohonutanga whai hua o te whakamaroke wera matū matū o te X60 paipa ngongo te whakamatautau pakeke me te whakamaroke wera o te mata te pakeke o te X60 pipeline ngongo rapunga, ka taea te whakamahi i te vickers hardness tester, te rockwell hardness tester, te rockwell hardness tester ranei hei whakamatautau, ko te mea anake te matotoru o te nitriding matotoru angiangi, te tikanga kaua e neke ake i te 0.7 mm, ka kore e taea te whakamahi i te rockwell hardness tester, ka taea te whakamahi Microhardness tester.

[2] X60 paipa mata tineia me te tempering wera maimoatanga
-- Ko te whakamaaramatanga o te mata me te whakamahana i te wera ka mahia ma te whakamahana whakawera, ma te mura ahi ranei.Ko nga tawhā hangarau matua ko te pakeke o te mata, te pakeke o te rohe me te hohonu o te paparanga whakapakeke whai hua.Ka taea te whakamahi i te whakamatautau pakeke a Vickers mo te whakamatautau pakeke, te toka, te mata ranei o te whakamatautau whakamaroke Rockwell.Ko te whiriwhiringa o te kaha whakamatautau (tauine) e pa ana ki te hohonutanga o te paparanga whakapakeke whai hua me te pakeke o te mata o te paipa X60.E toru nga momo mita pakeke.

Vickers pakeke tester he tikanga nui ki te whakamatautau i te pakeke mata o wera tukinotia X60 paipa paipa.Ka taea e ia te whakamahi i te kaha whakamatautau 0.5 ~ 100kg ki te whakamatautau i te paparanga whakapakeke o te mata he kikokore rite 0.05mm.Ko tona tika ko te teitei, a ka taea e ia te wehewehe i te rereketanga iti o te pakeke o te mata o te wera wera X60 paipa paipa.I tua atu, ko te hohonutanga o te paparanga whakapakeke whai hua ka ine ano e te vickers hardness tester, no reira he mea tika ki te whakauru i te Vickers tester pakeke mo nga waeine e kawe ana i te maimoatanga wera o te mata, te whakamahi ranei i te maha o nga waahanga mahi maimoatanga wera mata.

-- He tino pai hoki te whakamatautau whakamaroke pakeke o Rockwell mo te whakamatautau i te pakeke o te paipa paipa X60 paipa.E toru nga unahi mo te whakamaarama whakamaroke Rockwell mata hei whiriwhiri.Ka taea te whakamatautau i nga momo raina X60 kua whakapakeke i te mata me te hohonu o te whakapakeke pai ake i te 0.1mm.Ahakoa ko te tika o te whakamaarama pakeke o Rockwell kaore i te teitei ake i te whakamaarama pakeke o te Vickers, ka taea e ia te whakatutuki i nga whakaritenga hei tikanga whakamatautau mo te whakahaere kounga me te tirotiro i nga tikanga i roto i nga tipu maimoatanga wera.I tua atu, kei a ia ano nga ahuatanga o te mahi ngawari, te whakamahi watea, te utu iti, te ine tere, ka taea te korero tika i te uara pakeke, me etahi atu. whakamatautau kino.He mea nui tenei mo te tukatuka paipa X60 me nga tipu hanga miihini.

-- Ka taea hoki te whakamahi i te whakamaarama pakeke o Rockwell ina he matotoru te paparanga whakapakeke o te mata.A, no te te matotoru o te paparanga whakapakeke o te maimoatanga wera ko 0.4 ~ 0.8mm, ka taea te whakamahi i te tauine HRA, ka nui atu i te 0.8mm te matotoru o te paparanga pakeke, ka taea te whakamahi i te tauine HRC.

-- Ko nga uara pakeke o Vickers, Rockwell me Surface Rockwell ka ngawari te huri ki nga uara pakeke, tuhi, kaiwhakamahi ranei.Ko nga ripanga whakawhiti e rite ana ka tukuna i roto i nga paerewa o te ao ISO, paerewa Amerika ASTM me te paerewa Hainamana GB/T.

[3] Te maimoatanga wera o te rohe
-- Mena ka hiahiatia kia teitei te pakeke o nga waahanga, ka taea te whakahaere i te whakamahana wera whakamahana me etahi atu tikanga.Ko enei paipa paipa paipa X60 te tikanga me tohu te waahi o te maimoatanga wera wera o te rohe me te uara pakeke o te rohe i runga i te tuhi.Ko te whakamatautau pakeke o te paipa X60 me whakahaere ki te waahi kua tohua.Ka taea e te taputapu whakamatautau pakeke te whakamahi i te whakamaarama pakeke o Rockwell, te whakamatautau i te uara pakeke o te HRC, penei i te papanga whakamaroke whakamaarama wera he papaku, ka taea te whakamahi i te whakamaarama pakeke o Rockwell, te whakamatautau i te uara pakeke HRN.
