Ko ngā paipa pēhanga teitei o te muka basalt, he ātete ki te waikura, he mama, he kaha teitei, he iti te ātete ki te kawe wai, ā, he roa te ora mahi, e whakamahia whānuitia ana i roto i ngā mahi matū hinu, rererangi, hanga me ētahi atu mara. Ko ōna āhuatanga matua ko: te ātete ki te waikura o te H2S, CO2, te tote, me ētahi atu, he iti te kohi tauine, he iti te ware pi, he pai te rere o te mahi, he 1.5 ngā wā te tauwehenga rere o te paipa maitai, engari he tino kaha te miihini, he mama, he iti te utu tāutanga, he neke atu i te 30 tau te roa o te ora hoahoa, ā, i ētahi kaupapa, ahakoa te 50 tau te whakamahinga, kāore he raruraru. Ko ōna tono matua ko: ngā paipa tuku hinu mata, hau māori me te wai māori; ngā paipa pēhanga teitei pēnei i te weronga parakaingaki me ngā paipa hinu raro; ngā paipa tukanga matū hinu; ngā paipa tuku parakaingaki me te maimoatanga parakaingaki o te mara hinu; ngā paipa spa, me ētahi atu.
Ngā painga mahi o te paipa pēhanga-teitei muka basalt:
(1) He ātete pai rawa atu ki te waikura
E toru ngā wāhanga o te hanganga o te paipa pēhanga-teitei muka basalt: te paparanga arai o roto, te paparanga hanganga me te paparanga tiaki o waho. I roto i ēnei, he nui te ihirangi kapia o te paparanga arai o roto, neke atu i te 70% te nuinga, ā, ko te ihirangi kapia o te paparanga whai rawa i te kapia i runga i tōna mata o roto he teitei ki te 95%. Ki te whakatauritea ki ngā paipa maitai, he pai ake te ātete ki te waikura, pērā i te waikawa kaha me te kawakore, ngā momo otinga tote kore-waro, ngā rauemi waikura, te hauwai whanariki, te hauhā waro, ngā momo surfactants, ngā otinga polymer, ngā momo whakarewa waro, me ētahi atu. Mena ka whiriwhiria pai te hanganga kapia, ka taea e ngā paipa pēhanga-teitei muka basalt te tu atu mō te wā roa (haunga te waikawa kukū, te kawakore kaha me te HF).
(2) He ātete pai ki te ngenge me te roa o te ora ratonga
Neke atu i te 20 tau te roa o te ora hoahoa o te paipa pēhanga-teitei muka basalt, ā, he maha tonu ngā wā ka ora tonu i muri i te neke atu i te 30 tau o te whakamahinga, ā, kāore he mahi tiaki i te roanga o tōna oranga mahi.
(3) Te kaha ki te pupuri i te pēhanga teitei
Ko te taumata pēhanga noa o te paipa pēhanga teitei muka basalt he 3.5 MPa-25 MPa (tae atu ki te 35 MPa, i runga i te matotoru o te pakitara me te tatau), he nui ake te ātete ki te pēhanga i ērā atu paipa kore-whakarewa.
(4) Mama, ngāwari ki te tāuta me te kawe
Ko te taumaha motuhake o te paipa pēhanga-teitei muka Xuan Yan he tata ki te 1.6, he 1/4 ki te 1/5 noa iho o te paipa maitai, te paipa rino maka rānei, ā, e whakaatu ana te tono tūturu i raro i te kaupapa o te pēhanga ā-roto kotahi, ko te taumaha o te paipa FRP o te diameter me te roa he tata ki te 28% o te taumaha o te paipa maitai.
(5) Te kaha teitei me ngā āhuatanga miihini whaitake
Ko te kaha kume o te paipa muka-pēhanga teitei o te muka basalt he 200-320MPa, he tata ki te paipa maitai, engari he 4 ngā wā te kaha ake i tērā. I roto i te hoahoa hanganga, ka taea te whakaiti i te taumaha o te paipa, ā, he tino ngāwari te tāutanga.
(6) Ngā āhuatanga kē atu:
Ehara i te mea ngāwari ki te whakapūtā me te whakamātao, he iti te ātete ki te rere, he pai ngā āhuatanga whakamahana hiko, he ngāwari te hono, he kaha teitei, he iti te kawe wera, he iti te ahotea wera.
