Āe, ka taea te whakarite i ngā ngongo ahi ki ngā roa me ngā diameter motuhake, mai i te DN25 ki te DN100. Ka tapahia e au ngā ngongo ki te roa e hiahiatia ana, ā, ka whakatikatikahia ngā diameter kia tutuki ai ngā whakaritenga rere me te pēhanga mō ngā momo mahi.
He aha ngā rauemi e whakamahia whānuitia ana mō ngā ngongo ahi?
He mea hanga pinepine ngā ngongo ahi mai iPVC, PU, EPDM rānei. He rerekē ngā painga o ia rauemi. Hei tauira, he māmā te PVC, he ātete te PU ki te pakū, ā, he tino pai te EPDM ki te ātete ki te wera me te matū. Ka whiriwhiria e au ngā rauemi i runga i ngā hiahia taiao me te whakahaere.
Me pēhea te whakarite kia hototahi ngā ngongo me ngā hononga?
Hei whakarite i te hototahitanga, ka tirohia e au te momo hononga, te rahi o ngā miro, me ngā paerewa tiaki ahi ā-rohe. Mā te taurite i ēnei whakaritenga ka noho haumaru te hononga, ā, ka ārai i ngā whakaroa i ngā mahi nui.
He aha i wātea ai ngā ngongo ahi i ngā tae rerekē?
He mā, he whero rānei ngā ngongo ahi hei tohu i tō rātou whakamahinga. Ko ngā ngongo mā he mea noa mō ngā mahi ahumahi, ahuwhenua rānei, ko ngā ngongo whero ia he mea noa mō te tinei ahi. Ka whakataurite tonu ahau i te tae ki te tono kia kore ai e pōhēhē i ngā wā ohorere.
