Rōpū Rino o te Kuinie whakarato ana i te whānuitanga katoa o ngā maimoatanga mata ārai-waikura kua whakaritea mōNgā puranga paipa maitai ASTM A500, e kapi ana i ngā tono tuku iho o uta me ngā taiao waikura kino o te moana, o tai, me raro whenua. Kei a mātou ngā kōwhiringa paninga ngāwari hei taurite i ngā tahua kaupapa rerekē me ngā whakaritenga roa o te ratonga.
1. Mata Rino Mangu
Kāore he paninga tāpiri mō te whakaotinga maitai pango taketake, ā, ka honoa ki te maimoatanga ā-hinu ā-wāhanga. He kōwhiringa utu iti tēnei, he tino pai mō ngā kaupapa hanga whenua tuku iho, ngā mahi hanganga o roto me ngā wāhanga e hiahia ana kia tapahia tuarua, kia whakarewahia, kia tukatukahia anō hoki. Ka tukuna e tēnei whakaotinga he mahi taketake pumau, ā, ka tutuki i a ia ngā tono ā-wāhanga me te whakamahinga hanganga o te hangarau turanga noa.
2. Paninga Epoxy Hononga (FBE)
Ko te paninga FBE he maimoatanga tiaki paparanga kotahi te mahi teitei e whakamahia ana e te tohunga ki ngā mata o ngā paipa rino. He tino pumau te matū, ā, he ātete pai ki te pirau mai i te waikawa, te kawakore, te tote me ngā momo matū rerekē. He kaha te piri me te ātete pai ki te pakū, ka whakaratohia e tēnei paninga he tiaki ā-waikura roa, he pai mō ngā taiao ahumahi, ngā āhuatanga whakapā matū me ngā hanganga turanga o raro whenua me ngā whakaritenga pakari.
3. Paninga Ārai-Waikura Maha-Papa 3PE
Ko te paninga hiato papa-toru 3PE he otinga ā-taumata mō ngā āhuatanga hangarau uaua, he mea tito mai i tētahi pūnaha hanganga papa-toru ngaio: te paparanga tuatahi epoxy, te paparanga piri waenga me te paparanga tiaki polyethylene o waho. Ka tutuki i te hoahoa hanganga whakauru te huinga tino pai o te ātete ki te waikura matū, te ātete pānga miihini me te mahi whakamarumaru ā-wai.
