Ngā ngongo whakawhiti wera kowiri tira me ngā ngongo whakawhiti wera parahi Ngā rerekētanga me ngā painga
Ka kitea whānuitia te rerekētanga i waenga i ngā whakawhiti wera ngongo kowiri tira me ngā whakawhiti wera ngongo parahi. He rerekē ngā rauemi e whakamahia ana, ko tētahi he kowiri tira, ko tētahi he parahi. Koinei te rerekētanga o ngā rauemi. Ina whiriwhiria ēnei momo ngongo e rua, ka whakaarohia te kaha whakawhiti wera me te ātete ki te waikura.
E mōhio ana tātou katoa he iti ake te tūponotanga o te poke o ngā ngongo parahi i ngā ngongo kowiri tira. Kāore ngā kohua arumoni o tāwāhi e whakamahi i te wai hei rongoā i ngā taputapu, engari he 15 tau te roa o tō rātou oranga. Ko te take, ahakoa ka taea e te wai te hanga unahi i runga i te pakitara o te ngongo parahi, ka puta he unahi pupuhi anake. I tēnei wā, mena ka whakanuia te tere rere o te wai, kāore e taea te whakatakoto i te unahi.
Ko te tuarua ko te whakaaro ki te mahi whakawhiti wera. He teitei ake te kawe wera o te parahi i te kowiri tira, nō reira he teitei ake te tauwehenga whakawhiti wera o ngā ngongo parahi o taua āhua i te kowiri tira. Nō reira, ko ngā ngongo whakawhiti wera e whakamahia ana i roto i te whakapūmau whakamomona he mea hanga ki te parahi.
Tuatoru, he nui ake te kaha o te kowiri tira i te parahi, nō reira kua kite tātou ināianei he kowiri tira te pereti whakawhiti wera, engari he parahi anō hoki te pereti taketake. He pono, he nui ake te utu o te parahi i te kowiri tira.
I te wā e whiriwhiri ana tātou i tētahi whakawhiti wera, me whai whakaaro tātou ki ngā āhuatanga maha. He maha ngā whakawhiti wera kowiri tira kei te mākete ināianei, ā, kua tino whanake te umanga ngongo whakawhiti wera kowiri tira.
He nui ngā ngongo whakawhiti wera motuhake a Saky Steel me te paerewa GB13296-2013 me te paerewa GB/T21833-2008 puta noa i te tau; ngā whakatakotoranga: 38*2, 38*1.5, 32*2, 32*1.5, 25*2.5, 25*2, 25 *1.5, 19*2, 19*1.5 te roa tae atu ki te 30 mita, ngā rauemi: TP304, 304L, TP316L, F321, S22053, 310S, ka taea te tapahi ki tetahi rahi, ā, ka taea te hanga i ngā pupuhi, ngā pupuhi, ngā nakahi mō ngā kiritaki. Momo ngongo, koiri ārai namu, ngongo miro-T, ngongo whai tara, ngongo āhua-U, ngongo āhua-U kōpikopiko me te otinga totoka wāhanga āhua-U.
