Te Hiranga o ngā Paipa Whakarewa Takirua me ngā Paipa Whakarārangihia ki te Polyurethane i roto i te Whakarewa Paipa

Paipa takirua kua whakarewainae pā ana ki te paipa kua whakapirihia takirua hei hanga i tētahi hononga kaha ake, pakari ake. He mea whakamahi noa tēnei momo paipa i roto i te hanganga paipa, ina koa he mea nui te kounga me te kaha o te whakapiringa. Ko te tukanga whakapiringa takirua ko te whakamahi i ngā tikanga whakapiringa hei whakakotahi i ngā paipa e rua kia pai ai te hononga kaha, kia kore e pakaru. Ehara i te mea ka whakarei ake tēnei i te kaha me te pakari o te paipa anake, engari ka whakaitihia hoki te mōrearea o ngā hapa whakapiringa me ngā turuturu pea.

Polyurethane paipa kua whakarārangihia, i tētahi atu ringa, he paipa kua whakakikoruatia ki te paninga polyurethane e whakarato ana i te tiaki atu i te waikura, te pakū, me te whakaeke matū. Ka pania te arai ki te mata o roto o te paipa hei hanga i tētahi arai i waenganui i te wai e haria ana me te mata whakarewa o te paipa. He tino whai hua ngā paipa kua whakakikoruatia ki te polyurethane mō ngā paipa e whakamahia ana hei kawe i ngā matū waikura, hei whakahaere rānei i roto i ngā āhuatanga taiao kino. Ehara i te mea ka roa ake te ora o ō paipa i ngā arai polyurethane, engari ka whakaitihia hoki te mōrearea o ngā turuturu me ngā utu tiaki.

Hei tāpiritanga, ko te whai huatanga o te whakaputanga ongā paipa maitai porowhitahe nui ake te teitei i tērā o ngā paipa rino kore hononga. Mō ngā paipa kore hononga, ko te tukanga whakaputa ko te whakaputa i tētahi maitai totoka mā roto i tētahi tokotoko poka, ka hua ake he tukanga whakaputa puhoi ake, he uaua ake hoki. He rerekē, ka taea te hanga paipa porowhita kua whakapirihia ki ngā diameter me ngā roa nui ake, ka hua ake he wā whakaputa poto ake, he pai ake hoki te whai hua. Mā tēnei ka whakarite kia rite tonu te tuku o ngā paipa kounga teitei i roto i ngā wā poto ake, ka waiho hei otinga pono me te penapena wā mō ngā momo ahumahi.

Ko tētahi atu painga nui o ngā paipa whakarewa porowhita ko tōna ātete pai ki te pēhanga o waho me te ahotea miihini. Ka whakaratohia e ngā whakarewa he roa ake te mau, ka taea ai e ēnei paipa te tu atu ki ngā pēhanga teitei ake i ngā paipa kore hononga. He mea nui tēnei āhuatanga mō ngā tono i roto i te umanga hinu me te hau, ina pāngia ngā paipa e ngā pēhanga nui o roto me waho. Mā te whakamahi i ngā paipa whakarewa porowhita, ka taea e ngā kamupene te whakarite kia haumaru, kia whai hua hoki te kawe i ēnei rauemi nui.
