Whakataki Hua
Ko te paipa maitai kore hononga ASTM A106 he paipa maitai kore hononga i hangaia ki te rauemi maitai waro paerewa o Amerika. He rīpene maitai roa me te tapahanga tuwhera, kāore he hononga huri noa i te taha. He tapahanga tuwhera ngā paipa maitai, ā, he whānuitia te whakamahinga hei paipa mō te kawe wai, i te nuinga o te wā i roto i ngā taiao pāmahana teitei me te pēhanga teitei. Ka taea te wehewehe i ngā paipa maitai kore hononga ASTM A106 ki ngā paipa hurihuri wera, ngā paipa hurihuri matao, ngā paipa kumea matao, ngā paipa whakaputa, me ētahi atu, e ai ki ngā tikanga whakaputa rerekē. Ko ngā paipa kore hononga hurihuri wera te nuinga o te wā ka hangaia i runga i ngā wae hurihuri paipa aunoa. Ka tirotirohia te ngongo totoka, ka tangohia ngā hapa o te mata, ka tapahia kia rite ki te roa e hiahiatia ana, ka pokapū ki te mata pito o te ngongo, ka tukuna ki te oumu whakamahana hei whakamahana, ka pokaia ki runga i te mīhini pokaia. I te wā e pokaia ana, ka hurihuri tonu te ngongo, ka neke whakamua, ā, i raro i te mahi a te mira hurihuri me te tihi, ka puta he kōhao i roto i te ngongo pakaru, e kiia nei ko te ngongo capillary. Kātahi ka tukuna ki te mīhini hurihuri paipa aunoa hei hurihuri anō, ā, ka whakatikatikahia te matotoru o te pakitara puta noa i te mīhini. Ka whakamahia te mīhini ine mō te ine kia tutuki ai ngā whakaritenga paerewa. He tikanga matatau te whakamahi i te mira hurihuri tonu hei whakaputa i ngā paipa kore-whakarewa ASTM A106. He whānuitia ngā whakamahinga o ngā paipa kore-whakarewa ASTM A106, ko te nuinga he paipa, he wāhanga hanganga rānei mō te kawe wai. He rerekē ēnei tukanga e rua i runga i te tika, te kounga o te mata, te rahi iti rawa, ngā āhuatanga miihini, me te hanganga moroiti.
Te mahi ā-mīhini

Ko te paipa maitai kore-whakairo ASTM A106Gr.B he maitai waro-iti e whakamahia whānuitia ana, e whakamahia whānuitia ana i roto i ngā ahumahi hinu, matū me te pūwero. He pai ngā āhuatanga miihini o te rauemi. He rite te paipa maitai A106-B ki te paipa maitai kore-whakairo 20 o tōku whenua, ā, e whakatinana ana i te paerewa paipa maitai kore-whakairo waro pāmahana-tiketike ASTM A106/A106M, te taumata B. Ka kitea tēnei mai i te paerewa paipa tipu matū me te whare hanga hinu ASME B31.3: Awhe pāmahana whakamahinga rauemi A106: -28.9~565℃.
Paipa maitai kore hononga mahi whānui ASTM A53, e tika ana mō ngā pūnaha paipa pēhanga, ngā paipa paipa me ngā paipa mahi whānui me ngā pāmahana i raro i te 350°C.
Paipa maitai kore hononga ASTM A106 mō te mahi pāmahana teitei, he pai mō te pāmahana teitei. E hangai ana ki te paerewa ā-motu Nama 20 paipa maitai.
Ko te ASTM te paerewa a te American Materials Association, he rerekē tēnei i te tikanga whakarōpū ā-rohe, nō reira kāore he paerewa ōrite pakari. He maha ngā whakatakotoranga rerekē o ngā hua i raro i te tauira kotahi, i runga i tō whakamahinga motuhake.
E rua ngā tukanga o te paipa maitai kore hononga ASTM A106: te kume makariri me te hurihuri wera. Haunga ngā tukanga whakaputa rerekē, he rerekē te tika, te kounga o te mata, te rahi iti rawa, ngā āhuatanga miihini, me te hanganga whakahaere o ēnei e rua. He whānuitia te whakamahinga i roto i ngā momo ahumahi pēnei i te hinu, te ahumahi matū, ngā kohua, ngā teihana hiko, ngā kaipuke, te hanga mīhini, ngā motuka, te rererangi, te ātea, te pūngao, te whenua, te hanga, me te ahumahi hōia.
