Ko te pakeke o te paipa maitai e pā ana ki te kaha o te rauemi ki te ātete i te hurihanga i raro i te kaha o waho. Ko te pakeke tētahi o ngā tohu nui o te mahi a te rauemi.
I roto i te hanga me te whakamahinga o ngā paipa rino, he mea tino nui te whakatau i tōna pakeke. Ka taea te ine i te pakeke o ngā paipa rino mā roto i ngā momo taputapu whakamātautau pakeke pērā i a Rockwell, Brinell, me Vickers i hangaia e Laizhou Laihua Testing Instrument Factory, ā, ka taea te whakarite kia rite ki te hiahia. Ko ngā tikanga ine matua ko ēnei e whai ake nei:
1. Tikanga whakamātautau pakeke o Rockwell
Ko te whakamātautau pakeke o Rockwell te tikanga e whakamahia whānuitia ana i tēnei wā, ā, ko te HRC te tuarua o ngā paerewa paipa maitai ki te pakeke o Brinell, arā, ko te HB. Ka ine i te hohonutanga o te kōhao, ā, ka taea te whakamahi hei ine i ngā rauemi whakarewa mai i te tino ngohengohe ki te tino mārō. He māmā ake i te tikanga whakamātautau Brinell.
2. Tikanga whakamātautau pakeke Brinell
E whakamahia whānuitia ana hoki te tikanga whakamātautau pakeke Brinell i roto i te ao ahumahi. E whakamahia whānuitia ana i roto i ngā paerewa paipa maitai kore hononga. Ko te pakeke o te rauemi ka whakaatuhia i te nuinga o te wā mā te diameter o te kōhao. He māmā noa iho, he watea hoki, engari kāore e tika ana mō ngā paipa maitai pakeke ake, angiangi ake rānei.
3. Tikanga whakamātautau pakeke a Vickers
E whakamahia whānuitia ana hoki te whakamātautau pakeke a Vickers. Kei a ia ngā painga matua o ngā tikanga whakamātautau a Brinell me Rockwell, engari kua hinga i a ia ō rāua ngoikoretanga matua. He pai mō te whakamātautau pakeke o ngā rauemi rerekē, engari kāore i te pai mō ngā tauira he iti te diameter. Ehara i te mea ngāwari pērā i te tikanga whakamātautau a Rockwell, ā, he onge te whakamahinga i roto i ngā paerewa paipa maitai.
