He mea nui te mārama ki ngā rerekētanga i waenga i ngā momo taumata i te wā e whiriwhiri ana i te ngongo parahi tika mō tō kaupapa. He tohunga a Jindalai Steel Group Co., Ltd. ki te hanga i te whānuitanga o ngā momo ngongo parahi, tae atu ki ngā ngongo parahi kua whakakorea te hauota T1, T2, T3, TU1, TU2, me te TP2. He āhuatanga ahurei kei ia momo e tika ana mō ngā tono motuhake, inā koa i roto i ngā rāngai pouaka whakamātao me ngā paipa.

Ngā rerekētanga i waenga i ngā tohu o ngā paipa parahi

 E mōhiotia ana ngā ngongo parahi T2 mō tōna kawe hiko pai rawa atu, ā, e whakamahia ana i roto i ngā mahi hiko. I tētahi atu taha, he kaha ake ngā ngongo parahi T3, ā, e whakamahia ana i roto i ngā mahi e hiahia ana kia roa ake te mau. E whakamahia whānuitia ana ngā ngongo parahi TU1 me TU2 i roto i ngā pūnaha putorino me te whakamahana nā te mea he tino ātete ki te waikura me te ngāwari ki te hanga. He tino painga ngā ngongo parahi TP2 kua tangohia te waikura mai i te phosphorus i roto i ngā taiao e tino nui ana te ātete ki te waikura.

 I te wā e whiriwhiri ana i waenga i ēnei momo, whakaarohia ngā whakaritenga motuhake o tō tono. Mō ngā raina pouaka whakamātao i roto i ngā hauhautanga me ngā pouaka whakamātao, ko ngā ngongo parahi T2 me TP2 te mea e pai ake ana nā te mea he kawe wera me te ātete ki te waikura.

He aha i whiriwhiri ai i te whakamatao ngongo parahi?

 Ko ngā ngongo parahi te rauemi pai mō ngā paipa whakamātao mō ētahi take. Tuatahi, nā te pai o te kawe wera o te parahi ki te konumohe me te maitai ka taea te whakawhiti wera pai. Nā tēnei whakawhiti wera pai ka nui te penapena pūngao me te whakapai ake i te mahi i roto i ngā pūnaha hauhautanga me te whakamātao. Hei tāpiri, nā ngā āhuatanga patu huakita tūturu o te parahi i pai ai te haumaru mō ngā tono kai me te inu.

 Ki te whakataurite, ahakoa he mama ngā paipa konumohe, kāore e pai te kawe i te wera, ā, he ngāwari ake ki te waikura. Ahakoa he kaha ngā paipa rino, he taumaha ake, ā, he ngāwari ki te waikura i roto i te wā, ka arahi pea ki ngā turuturu me ngā pakaru o te pūnaha.

Ngā paerewa mō ngā paipa parahi mō te wai inu

 I roto i ngā tono wai inu, me tutuki ngā paipa parahi i ngā paerewa motuhake hei whakarite i te haumaru me te kounga. Kua whakatūhia e te American National Standards Institute (ANSI) me te American Society for Testing and Materials (ASTM) he aratohu mō ngā paipa parahi, tae atu ki ngā whakaritenga mō ngā "paipa parahi kounga kai". Me kore he poke kino i roto i tēnei paipa, ā, me whai tiwhikete mai i ngā whakahaere pēnei i a NSF International hei whakarite he haumaru ngā rauemi e whakamahia ana mō te wai inu.

Paipa parahi kore-tuitui me te paipa parahi whakarewa

 Ko tētahi atu mea hei whakaaroaro māu i te wā e whiriwhiri ana i ngā ngongo parahi ko te hononga kore-tuinga, me te hononga parahi kua whakarewaina. Ka hangaia ngā ngongo parahi hononga kore-tuinga, ā, ka puta he hanganga ōrite e whakanui ana i te kaha me te whakaiti i te tūponotanga o ngā turuturu. He tino painga tēnei mō ngā tono pēhanga teitei, pērā i ngā raina pouaka whakamātao.

 He iti ake te utu o ngā ngongo parahi whakarewa, engari tera pea ka iti te mahi nā te ngoikore o te hononga whakarewa. He pai ēnei mō ngā tono pēhanga iti, mō ngā wāhi rānei ko te utu te mea nui.

hei whakamutunga

 Hei whakamutunga, he mea nui te whiriwhiri i te momo tika o ngā ngongo parahi hei whakarite i te whai huatanga me te haumaru o ō pūnaha whakamatao me ngā pūnaha paipa. Kei a Jindalai Steel Group Co., Ltd. he raina whānui o ngā ngongo parahi, tae atu ki te T2, T3, TU1, TU2, me te TP2, ia mea i hangaia kia tutuki ai ngā hiahia tono motuhake. Mā te mārama ki ngā rerekētanga i waenga i ēnei momo me ō rātou painga ka taea e koe te whakatau whai whakaaro hei whakarei ake i te mahi me te roa o te ora o tō pūnaha. Ahakoa e hiahia ana koe ki ngā ngongo parahi kore hononga, ki ngā ngongo whakarewa rānei, ka whakaratohia e ā mātou ngongo parahi kounga teitei, i hangaia kia tino pai, he hua tino pai ki a koe.
