I roto i ngā pūnaha paipa rino pēhanga ngāwari, ahakoa he iti ngā whakapiri (pērā i ngā pūtu, nati, me ngā gasket), he wāhanga nui hei whakarite i te piripono, te hanganga tika, me te mahi haumaru o ngā hononga paipa. EN4016, "Ngā paipa rino ngāwari, ngā taputapu, me ngā taputapu - Te tuku wai inu - Ngā whakaritenga me ngā tikanga whakamātautau," e whakatakoto ana i ngā whakaritenga hangarau mārama mō ngā whakapiri e whakamahia ana i roto i aua paipa. Kei roto i tēnei tuhinga ngā mōhiohio taketake mō ngā whakapiri i runga i tēnei paerewa.
Kāore te paerewa EN4016 e kapi noa i ngāngā paipa rino ngāwarime ngā hononga anō hoki, engari e whakamārama ana hoki i te mahi, ngā rauemi, me te tiaki i te waikura o ngā pūnaha whakapiri e whakamahia ana hei hono atu (tae atu ki ngā pūtu, ngā nati, me ngā whakamātao). Ko te whiriwhiri me te whakamahi i ngā whakapiri e tutuki ana i tēnei paerewa he mea nui hei whakarite i te tutuki me te haumaru o te pūnaha paipa katoa.
Ngā Whakaritenga Taketake mō ngā Whakamau
E ai ki te EN4016, me tutuki i ngā here e whakamahia ana i roto i ngā paipa rino ngāwari (ina koa ko ērā e whakamahia ana mō te tuku wai inu) ngā whakaritenga taketake e whai ake nei:
1. Ngā Āhuatanga Rauemi me ngā Āhuatanga Mīhini
- Ngā pūtu: me hanga i ngā rauemi e ranea ana te kaha me te pakari, pērā i te maitai waro, te maitai koranu rānei. Me 8.8 te iti rawa o te kounga o te āhuatanga miihini (arā, he 800 MPa te kaha kume me te 0.8 te ōwehenga kaha whakaputa). Mō ngā tono pēhanga teitei ake, me whakamahi pea ngā pūtu he 10.9, neke atu rānei te kaha.
- Ngā nati: me ōrite ki te kounga o te pūtu, me whakamahi i ngā nati kounga 8, 10 rānei, kia ōrite ai te hononga, kia kore ai hoki e marere ngā miro.
- Te āheinga hanga: me pai te āheinga hanga me te āheinga miihini kia kore ai he hapa o roto.
2. Ngā Mirome tutuki ki ngā paerewa miro ine ISO (hei tauira, ISO68-1, ISO261),kia ma, kia katoa, kia kore he pūwero, he kapiti, me ētahi atu hapa hei whakarite i te hononga maeneene i waenga i te pūtu me te nati.
3. Ngā Ahu me ngā Āteteme tutuki ngā whakaritenga manawanui kua tohua i roto i ngā tuhi hoahoa me ngā paerewa e tika ana (pēnei i te EN ISO 4014 me te EN ISO 4032) kia taea ai te whakawhiti me te ōrite i te huihuinga.
Nā te mea he maha ngā wā ka whakamahia ngā paipa rino ngāwari ki raro i te whenua, ki ngā taiao makuku rānei, ā, nā te mea ka kawe i te wai inu, he tino teitei te ātete ki te waikura o ngā whakapiri. He tino kaha ngā ture a te EN4016 mō tēnei:
1. Te Mōrearea o te Waikura
He tino ngāwari te waikura hikohiko o ngā here maitai waro i roto i ngā taiao makuku. Ka taea e te waikura nui te pakaru o te pūtu, te turuturu o ngā hononga, tae atu ki te pakaru o te pūnaha paipa.
Mō te pā atu ki te wai inu, me kore e paitini te paninga ārai-waikura, me kore e kakara, ā, me kore e pā ki te kounga o te wai.
2. Ngā Paninga Ārai-Waikura e Manakohia ana,E taunaki ana a EN 4016 i ngā maimoatanga ārai-waikura e whai ake nei mō ngā taiao wai inu:
Te whakapūmau wera-tō (HDG): He tikanga tiaki tino noa, he whai hua hoki tēnei. Whai muri i te whakapūmau me te whakapūmau, ka rumakina ngā whakapiri ki roto i te konutea rewa hei hanga i tētahi paparanga konutea-rino matotoru me tētahi paparanga konutea parakore.
Whakaritenga: Me tutuki te matotoru o te paparanga konutea i ngā paerewa e tika ana (pēnei i te ISO 10684), me whai matotoru toharite o te 50μm te iti rawa hei whakarite i te tiakitanga waikura mō te wā roa. Paninga Dacromet/Konutea-Kōrohiuma: He hangarau paninga ātete waikura kore-hauwai, i hangaia mā te paninga i te paraoa i hangaia mai i te paura konutea, te paura konumohe, me te waikawa kōrohiko, kātahi ka tunua ki te pāmahana teitei.
Ngā Painga: He ātete pai rawa atu ki te waikura (he pai ake i te whakapūkara wera-tuku o te matotoru ōrite), kāore he mōrearea o te pakarukaru hauwai, ā, he ōrite te paninga.
E tutuki katoa ana i ngā whakaritenga akuaku mō ngā rauemi e pā ana ki te wai inu.
Paninga Epoxy: Ka pania he kiriata tiaki kapia epoxy pakari ki te mata o te whakapiri mā te whakamahi i ngā tikanga pēnei i te rehu hiko.
Ngā Painga: He ātete matū tino pai, he ātaahua hoki te āhua. Heoi anō, me noho pūmau te paninga, ā, me kore e pakaru, nā te mea ka waikura pea.
ngā pūnaha paipa rino pēhanga ngāwari, ngā paipa rino ngāwari, te puna wai inu, EN4016, ngā hononga, ngā taputapu, ngā pūtu, ngā nati, ngā gasket, te hononga me te whakawera wera.
