Ko te Raupapa Ngongo 40 he paerewa matotoru pakitara noa mō ngā paipa, nō te pūnaha rahi o ANSI/ASME B36.10 (paipa maitai waro) rānei B36.19 (paipa kowiri tira). Ko te "Rārangi Whakatakotoranga" i konei e tohu ana i te matotoru o te pakitara o te paipa, ā, ko te Rārangi Whakatakotoranga 40 (e whakarapopototia ana ko Sch 40) te rēanga e whakamahia whānuitia ana, e whakamahia whānuitia ana hoki.
Ngā Āhuatanga o te Raupapa Ngongo 40:
Matotoru pakitara taurite:matotoru ake i te Āpitihanga 10 engari angiangi ake i te Āpitihanga 80.
Kaha pono:ka taea te tu atu i te pēhanga ngawari me te ahotea miihini.
Te whānui kaha:He nui ngā tono mō tēnei mea i roto i ngā mara ahumahi me ngā mara tangata whenua.
Ngā rauemi kanorau:he paipa rino waro pea, he paipa rino kore waikura, he paipa rino piauau rānei.
Ngā Whakamahinga Noa mō te Ngongo Rino 40:
Pūnaha tuku wai me te pūnaha rerenga wai
Paipa ahi
Te kawe hau māori me te mamaoa
Ngā paipa ahumahi me ngā wāhanga hanganga miihini
Ngā Whare me ngā Hanganga

Te Whakaritenga o te Hōtaka 40 me ētahi atu Whakatauritenga o te Hōtaka:
Hei tauira, mā te whakamahi i te diameter o te paipa e whakamahia whānuitia ana, he 2 inihi (2 inihi), whakaaturia ngā rerekētanga o te matotoru o te pakitara i waenga i te Āpitihanga 10, 40, me te 80:
| Rahi Paipa Ingoa (NPS) | Hōtaka 10 (Wāhanga 10) | Hōtaka 40 (Wāhanga 40) | Kaupapa 80 (Wāhanga 80) |
| 2" (OD 60.3 mm) | 2.77 mm | 3.91 mm | 5.54 mm |
| 3" (OD 88.9 mm) | 3.05 mm | 5.49 mm | 7.11 mm |
| 4" (OD 114.3 mm) | 3.38 mm | 6.02 mm | 8.18 mm |
| 6" (OD 168.3 mm) | 3.56 mm | 7.11 mm | 9.27 mm |
Sch 10: te mea angiangi rawa, te mea iti te utu, he pai mō ngā pūnaha ngaohiko iti.
Sch 40: Matotoru waenga, e whakamahia whānuitia ana, e taurite ana te kaha me te utu.
Sch 80: matotoru rawa, he kaha te ātete ki te pēhanga, he pai mō ngā tono ngaohiko teitei, kaha rānei.
He aha te painga o te paipa waro Youfa waitohu Schedule 40?
Hei kaihanga matua i roto i te umanga paipa rino o Haina, kua whakapumautia e Youfa Group tōna ingoa rongonui mā roto i ngā kaha whakaputa pakari, ngā hangarau tukatuka auaha, ngā tiwhikete hua pakari, me te whakapau kaha ki te hanga pumau.

Pūnaha Aroturuki:Ka tohaina he waehere tautuhi ahurei ki ia paipa hei aroturuki i te kounga mō te wā katoa, hei whakakaha i te kawenga me te pono.
4. Ngā Tiwhikete me ngā Paerewa Ārahi-Ahumahi
Tiwhikete Hua Kakariki ā-Motu:He maha ngā hua Youfa, tae atu ki ngā paipa o te Wāhanga 40, kua whakamanahia hei "Hua Hoahoa Kakariki" e te Manatū Ahumahi me te Hangarau Mōhiohio o Haina, e whakaatu ana i tō rātou hiranga taiao me te mahi.
Te Whakamihi ā-Ao:Ko ngā tiwhikete pēnei i te API 5L me te ISO 9001 e whakamana ana i tō rātou pai mō ngā kaupapa hinu me te hau o te ao.
5Te Whakapūmau ki te Oranga Tonutanga me te Hanganga Kakariki
Ngā Wheketere Kakariki:E toru o ana turanga whakaputa kua tohua ko "National Green Factories", ā, i whakawhiwhia a Jiangsu Youfa Pipe Co., Ltd. ki te taitara "Green Factory" i te tau 2024 mō ana pūnaha hangarua wai para me te whakaiti i ngā tukunga waro.
Ngā Kaupapa Whakaputa Ma:Nā ngā haumitanga neke atu i te RMB 22 miriona i te tau 2023 i whakapai ake i te whakahaere para me te whai huatanga o te pūngao, i whakaiti hoki i ngā tukunga kohu waikawa me te whakaputanga para morearea.
