Ko te kowiri tira he momo porowhita, engari he mea hanga ki te tukatuka rauemi kowiri tira, ka taea te whakamahi i nga umanga rereke. I tenei wa, kua whakamahia nuitia i roto i te ahumahi matū, te miihini, te hikohiko, te hiko hiko, te kakano, te rapa, te kai, nga taputapu hauora, te rererangi, te rererangi, te whakawhitiwhiti, te hinu me etahi atu mara ahumahi. Na he aha ona painga?
1. Kowiri tira whakawhiti wera pōkai te whakamahi i 0.5-0.8mm putorino-taiepa angiangi, whakapai ake i te mahi whakawhiti wera whānui. Me te waahi whakawhiti wera ano, ko te whakawhitinga wera katoa e tika ana ki te 2.121-8.408% teitei ake i tera o te coil parahi.
2. No te mea ko te kowiri tira he mea hanga ki te SUS304, SUS316 me etahi atu kowiri tira kowiri tira teitei, kia nui ake ai te pakeke, ka tino pai ake te tohu maitai o te putorino, no reira, he kaha te kaha o te paanga me te wiri.
3. Na te mea he maeneene te pakitara o roto o te kowiri tira, he kikokore te matotoru o te paparanga o raro o te rere o te rohenga rohe, e kore e whakapakari noa i te whakawhitinga wera, engari ka pai ake te mahi anti-scaling.
4. Hei whakakore i te ahotea fehokotaki'anga, te rauemi paipa maitai e whakamahia ana i roto i te kowiri tira pōkai he wera tukinotia i 1050 nekehanga i roto i te hau tiaki.
5. Ka whakamahia te kowiri tira mo te tirotiro i te rerenga, te whakamatautau pehanga ki te 10MPA, nga meneti 5 me te kore e heke te pehanga.
