Mowhiti Whakakī Kowiri tira PEX

Ko ngā mowhiti kume kowiri tira PEX he mea whakapiripiri ā-ringa tūturu e whakamahia ana hei hono i ngā paipa polyethylene (PEX) kua honoa-whiti ki ngā hononga parahi, polyoxymethylene (POM) rānei (pērā i ngā tī, ngā tuke, ngā hononga tika, me ētahi atu). Ko tā rātou kaupapa matua he hanga hononga paipa kaha, ātete-tauraki. Mā te kume ki tētahi taputapu, ka huri te āhua o te mowhiti kowiri tira mō ake tonu atu, ka mau tonu te paipa PEX ki ngā koi o te hononga, ka hanga he hiri kaha-teitei. Ka mahi hei whakakapi mō ngā kume tuku iho, ngā hononga pēhi-whakauru rānei, ka whakarato i te kaha kume ōrite me te pono teitei ake, ka waiho hei tētahi o ngā tikanga hononga tino rongonui i roto i ngā pūnaha paipa PEX hou.

Ko ngā whakamahinga matua ko ngā whare noho me ngā whare arumoni, ngā whare ā-tāone me ngā whare tūmatanui, ngā whakamahinga ahumahi, me ngā kaupapa tiaki me te whakahou. Ko te rauemi e whakamahia ana ko te maitai kore waikura raupapa AISI 300, ko te nuinga ko te maitai kore waikura 304 (A2 rānei), e tuku ana i te ātete pai ki te waikura me te kaha miihini. Ko ngā āhuatanga matua ko te ātete ki te waikura me te waikura, e whakarite ana i te whakamahinga roa i roto i ngā taiao mākū me te kore e waikura, e ārai ana i te poke o te wai, me te whakarato i te kaha piri pono, pumau hei ārai i te wetewete o ngā hononga nā te pēhanga o te pūnaha. He pai hoki te ngāwari o ēnei, e āhei ai te whakarerekētanga kirihou ōrite i raro i te mahi a ngā taputapu kume me te kore e pakaru.

Ko ngā āhuatanga me ngā painga o te hua e whai ake nei: Tuatahi, he tino pono, me ngā hononga miihini pumau e ātete ana i te wiri me ngā ru pēhanga, me te roa o te ratonga e rite ana ki te pūnaha paipa. Tuarua, he tere te tāutanga, e taea ai e te kaiwhakahaere mohio te whakaoti i te hononga i roto i ngā tekau hēkona noa iho, e tino whakapai ake ana i te pai o te hanga. Tuatoru, kāore he hiahia mō te wera, te mura tuwhera rānei, e taea ai te tāutanga makariri, he haumaru ake, ā, kāore he mōrearea ahi, me te kore e pā ki ētahi atu tukanga hanga. Tuawhā, ka taea te tirotiro tere me te whai kiko i te kounga o te hononga mā te whakamahi i ngā tohu kua kōpikopikotia me ngā ine haere/kore haere. Tuarima, mō te tiaki, tapahia noa te hononga kua kōpikopikotia ka hono anō mā te whakamahi i ngā hononga hou me ngā mowhiti kōpikopikotia. Tuaono, he hototahi pūnaha, e hanga ana i tētahi hoahoa pūnaha whānui kua arotauhia me ngā paipa PEX me ngā hononga kua ōrite.
