ASTM A490 me ngā Pūtu ASTM A325

He hanganga tapawhā taumaha ngā pūtu ASTM A490 me ASTM A325.pūtuE mōhio ana koe ki te rerekētanga i waenga i te ASTM A490 me te ASTM A325? I tēnei rā, me kōrero tātou mō tēnei mea.

Ko te whakautu māmā ko ngā pūtu hexagonal mahi-taumaha ASTM A490 he nui ake te kaha e hiahiatia ana i ngā pūtu hexagonal mahi-taumaha A325. Ko te kaha kume iti rawa o ngā pūtu A325 he 120ksi, ko te awhe kaha kume o ngā pūtu A490 he 150-173ksi.

Haunga tēnei, kei reira anō ētahi atu rerekētanga i waenganui i te A490 me te A325.

Te Hanganga o ngā Rauemi

• He mea hanga ngā pūtu hanganga A325 mai i te maitai waro waenga kaha-teitei, ā, ko ngā pūtu tino kitea i roto i te hanganga whare
• He mea hanga ngā pūtu hanganga A490 mai i te maitai pakari-wera-pai
• Ka taea te whakamahi i ngā pūtu hanganga A325whakapūmau wera-tōā, e kitea whānuitia ana me taua paninga. He rongonui ngā pūtu konukōre A325 nā ō rātou āhuatanga ātete ki te waikura.
• He kaha ake ngā pūtu hanganga A490, kāore e taea te whakakikoruatia ki te wai wera nā tēnei kaha. Nā te kaha kume teitei o ngā pūtu A490, ka mōrearea rātou ki te pakaru hauwai nā te whakakikoruatia. Ka taea e tēnei te arahi ki te pakaru wawe o te pūtu, ā, ka kore e kaha te hanganga.

Whirihoranga

Kei raro i te whakaritenga ASTM F490 ngā pūtu A3125 me A325, ā, e whakamahia ana mō ngā pūtu hanganga. I te nuinga o te wā, ko ngā pūtu hanganga he pūtu hex taumaha, he pūtu whakahaere kume rānei, he poto ake te roa, he poto ake i te miro noa, ā, kāore e taea te whakaiti i te whānui o te tinana.

E ai ki te tikanga, e whakaaetia ana ētahi tūāpapa. I mua i te tau 2016, he whakaritenga motuhake a ASTM A325 me ASTM A490. Mai i taua wā kua whakarōpūtia anō rāua hei akomanga i roto i te whakaritenga F3125. I te tīmatanga, me whai pane hex taumaha ngā pūtu A325 me A490, ā, kāore i whakaaetia ētahi atu whirihoranga. Hei tāpiri, kāore e taea te whakarerekē i te roa o te miro poto.

Heoi, e ai ki te whakatakotoranga hou o te F3125, ka whakaaetia tetahi momo pane, ā, ka taea te whakarerekē i te roa o te miro. Ka tohua ngā huringa ki ngā whirihoranga A325 me A490 noa mā te tāpiri i te "S" ki te tohu pari tuturu mō te pane.

Ko tētahi atu rerekētanga o te roa o te miro ko te hanga papatipu o ngā pūtu A325 i roto i te putanga miro-katoa, mena e whā ngā diameter, iti iho rānei te roa. E kiia ana tēnei momo pūtu ko te A325T. Kāore e wātea ana te putanga miro-katoa o tēnei pūtu A325 mō ngā pūtu A490.

Whakamātautau

Me whakamātautau te kaha hurihuri o ngā pūtu whakarewa A325 e hokona ana me te nati me te horoi whakapakeke. Mā te whakamātautau kaha hurihuri ka taea e te huihuinga pūtu te whakawhanake i te kaha piri tika. Hei angitu i te whakamātautau, me eke te huihuinga ki te iti rawa o ngā hurihanga me te whakatutuki i te taumahatanga e hiahiatia ana i mua i te pakaru e whakawhirinaki ana ki te diameter me te roa o te pūtu whakarewa A325. Nā te mea kāore e taea te whakarewa i ngā pūtu A490, kāore e tika tēnei whakamātautau.

Me whakaoti ngā pūtu A490 katoa i te whakamātautau matūriki aukume. Ka whakamahia tēnei whakamātautau hei whakarite kia kore he hapa o raro i te mata, he kapiti rānei i roto i te maitai o te pūtu A490. Kāore tēnei whakamātautau e hiahiatia mō ngā pūtu A325.

Raina Matua

Hei te mutunga, mā tō miihini e tohu ko tēhea momo o te pūtu hanganga F3125 e whakamahi, engari he mea nui kia mārama koe ki te rerekētanga i waenga i ngā momo A325 me A490. He kaha ake te momo A490 i te momo A325, engari ehara i te mea ko te kaha anake te mea e whakatau ana i te pūtu. Kāore e taea te whakatō wera i ngā pūtu A490, te whakakanapa rānei mā te miihini. Kāore te momo A325 i te tino kaha, engari he pūtu iti ake te utu ka taea te whakakanapa hei karo i te waikura.
