He pai te paipa o te hōtaka 40 mō ngā mahi hanganga?

Te Rangahau i te Hiranga o te SCH 40 i roto i te Hanganga Rino

E whakaaetia whānuitia ana te paipa Whakaritenga 40 hei paipa e whakamahia whānuitia ana, ā, he tino ngāwari hoki te urutau.te āhua opaipa maitai waroi roto i te rāngai maitai.Heoi anō, ka ara ake tētahi pātai i waenga i ngā miihini, ngā kaihoko, me ngā kaihanga: He pai te paipa Whakaritenga 40 mō ngā mahi hanganga?

Ka tūhuratia e tēnei tuhinga te whakamahinga o te Āpitihanga 40, me tōna hiranga i roto i ngā horopaki hanganga.

Te mārama ki te aha te "Kaupapa 40"
Kāore te tohu Āpitihanga 40 e tohu ana i te taumata rauemi, i te kaha rānei—e pā ana ki te matotoru o te pakitara o te paipa e whai ake neiASME/ASTMngā aratohu ā-ahu.

Mai i te ripanga ka kitea e tātou, ko te matotoru o te pakitara o te paipa 2-inihi o te Schedule 40 he 3.91 mm, ko te matotoru ia o te pakitara o te paipa 8-inihi he 8.18 mm. Ko ēnei inenga kua whakaritea e te ASME B36.10M, ko te nuinga mō ngā paipa pēhanga i roto i ngā pūnaha kawe wai.

I hangaia mō te pēhanga, ehara i te kawenga hanganga

Ko ngā paipa o te Wāhanga 40 ka hangaia kia rite ki ngā paerewa pēnei i te ASTM A53, ASTM A106, rāneiAPI 5L. Ko ēnei whakatakotoranga e aro nui ana ki te pupuri i te pehanga, te āheinga whakarewa, me te ātete ki te waikura, kaua ki te kaha hanganga.

Ko te tikanga o tēnei, kua hangaia ngā paipa kia tū atu ki te pēhanga o roto, kaua ki ngā pēhanga o waho pērā i te piko, te pēhanga rānei i roto i ngā anga hanganga.

Ka Taea te Whakamahinga Hanganga?

Āe—engari me ētahi here.

Ka taea te whakamahi i ngā paipa Whakaritenga 40 i roto i ngā kaupapa hanganga mama, kāore rānei i te tino hira, inā koa i roto i ngā tono pēnei i:

- Ngā ārai, ngā taiapa, me ngā ringaringa

- Ngā anga tautoko me ngā waeine whata

- Ngā pou tohu me ngā huihuinga iti o ngā poupou

I ēnei horopaki, he kōwhiringa ōhanga te Wāhanga 40 nā te mea he kaha rawaka mō ngā tono kore-tino nui, ā, he whānui hoki tōna wātea.

Ahakoa rā, ina whiriwhiria e mātou ngā hua mō ngā hanganga pikau kawenga, ngā wāhanga rānei i roto i ngā hoahoa hangarau me te hanganga kua whakamanahia, me whiriwhiri ngā paipa maitai kounga pērā i te ASTM A500, ASTM A252 rānei. Nā te mea he mea hanga motuhake ēnei mō te pakari o te hanganga, ā, ka whakamatautauria te mahi ā-mīhini.

Te Whakataurite i ngā Ngongo Hanganga o te Hōtaka 40 me te ASTM A500

E ai ki te ripanga, ina hiahiatia he kahah, he rite tonu te manawanui, me te mahi pumau i raro i te kawenga, ko te kōwhiringa pai ake ko te ASTM A500.

Ngā Whakaaro Whakamutunga

Te haere tonu o ngā paipa o te hōtaka 40Ko tētahi o ngā momo paipa rino e whakamahia whānuitia ana, ā, he iti hoki te utu e wātea ana. He tino pai mō ngā pūnaha wai, te hanga whānui, me ngā mahi hanganga māmā.

Heoi, he mea nui kia whiriwhiria he paipa rino, he ngongo rānei kua whaimanahia (pēnei i te ASTM A500, A252 rānei) mō ngā kaupapa e hiahia ana kia pono te hanganga hangarau.

Ehara i te mea ka whakarite noa tēnei i te ū ki ngā waehere hoahoa, engari ka whakarite hoki i te haumaru me te mahinga roa o tō kaupapa.
