ʻO ka Papa Kuhikuhi Tube 40 kahi kūlana mānoanoa o ka paia maʻamau no nā paipu, nona ka ʻōnaehana nui o ANSI/ASME B36.10 (paipu kila kalapona) a i ʻole B36.19 (paipu kila kila). Hōʻike ka "Papa Kuhikuhi" ma aneʻi i ka mānoanoa o ka paia o ka paipu, a ʻo ka Papa Kuhikuhi 40 (i hoʻopōkole ʻia ʻo Sch 40) ka papa i hoʻohana nui ʻia a hoʻohana nui ʻia.
Nā Hiʻohiʻona o ka Papa Kuhikuhi Tube 40:
Mānoanoa o ka paia waena:ʻoi aku ka mānoanoa ma mua o ka Papa Kuhikuhi 10 akā lahilahi ma mua o ka Papa Kuhikuhi 80.
Ikaika hilinaʻi:hiki ke kū i ke kaomi kaulike a me ke kaumaha mechanical.
Ka laulā ikaika:He nui nā noi ma nā ʻoihana kīwila a me nā ʻoihana.
Nā mea like ʻole:hiki ke hana i ka paipu kila kalapona, ka paipu kila kila, a i ʻole ka paipu kila galvanized.

He aha ka pōmaikaʻi o ka Youfa Brand Schedule 40 Carbon Pipe?
Ma ke ʻano he mea hana alakaʻi i ka ʻoihana paipu kila ma Kina, ua hoʻokumu ʻo Youfa Group i kona kaulana ma o nā hiki hana ikaika, nā ʻenehana hana hou, nā palapala hōʻoia huahana koʻikoʻi, a me ka hoʻokō ʻana i ka hana hoʻomau.
1. Ka Mana Hana Kiʻekiʻe a me ka Unahi
Hoʻokele ʻo Youfa Group i 8 mau kahua hana ma Kina (e like me Tianjin, Hebei, Jiangsu, a me Yunnan), i lako me nā laina hana ma mua o 300 e hoʻokō pū ana i kahi hana makahiki ma mua o 20 miliona tone o nā paipu kila. Loaʻa i nā paipu kila kalapona Schedule 40 o ka hui, kahi laina huahana koʻikoʻi, ka pōmaikaʻi mai kēia unahi nui, e hōʻoiaʻiʻo ana i ka lako paʻa a me ka pono o ke kumukūʻai no nā papahana aila, kinoea, a me nā ʻoihana nui.
Alakaʻi Mākeke:Ua helu mua ʻo Youfa ma ke kūʻai aku ʻana i nā paipu kila i hoʻoheheʻe ʻia ma Kina no 19 mau makahiki i ka lālani, me kahi māhele mākeke kūloko o kahi 35% no nā paipu galvanized wela.
Hōʻea Honua:Hoʻokuʻu ʻia aku nā huahana i nā ʻāina he 100 a ʻoi, me ʻAsia Hikina Hema a me ka Hikina Waena, i kākoʻo ʻia e nā hoʻolālā e hoʻonui i nā kahua hana ma nā ʻāina ʻē.
2. Nā Kikoʻī Piha a me ka Hoʻopilikino ʻana
Ka laulā o ke anawaena:Mai DN15 a i DN1200, e hoʻokipa ana i nā noi i ka hoʻoili ʻaila a me ke kinoea, ke kākoʻo kūkulu, a me nā pono hana ma lalo o ka honua.
Hoʻopilikino ʻana:Hoʻoikaika nā uhi koho (e laʻa, epoxy resin, polyethylene) i ke kūpaʻa ʻana i ka pala no nā wahi ʻino e like me ka ʻeli ʻana ma waho o ke kai a i ʻole ka hana kemika.
3. Ka Hana Holomua a me ka Mana Hoʻomalu Kūlana
Hana Hana Hou:Loaʻa i ka ʻoihana he 188 mau palapala sila i ʻae ʻia, me nā mīkini hoʻopili paipu aunoa a me nā ʻōnaehana galvanizing mālama ikehu, e hoʻonui ana i ka pono hana a hoʻemi i nā kumukūʻai.
CNAS Nā Keʻena Hoʻokolohua i Hōʻoia ʻia:ʻElima mau keʻena hoʻokolohua i ʻike ʻia e ka ʻāina e hana ana ma mua o 200 mau hoʻokolohua maikaʻi, me ke kaomi hydrostatic, ka nānā ʻana i ka hoʻohui kemika, a me nā hoʻāʻo ʻole e luku ai, e hōʻoiaʻiʻo ana i ka mālama ʻana me ASTM A53, GB/T 3091, a me nā kūlana honua ʻē aʻe.
ʻŌnaehana Hahai:Ua hāʻawi ʻia kēlā me kēia paipu i kahi code ʻike kūikawā no ka nānā ʻana i ka maikaʻi o ke ola holoʻokoʻa, e hoʻoikaika ana i ke kuleana a me ka hilinaʻi.
4. Nā Palapala Hōʻoia a me nā Kūlana Alakaʻi ʻOihana
Palapala Hōʻoia Huahana ʻŌmaʻomaʻo Lahui:Ua hōʻoia ʻia kekahi mau huahana Youfa, me nā paipu Schedule 40, ʻo ia hoʻi nā "Green Design Products" e ke Kuhina ʻOihana a me ka ʻIke ʻIke o Kina, e hōʻike ana i ko lākou kūlana maikaʻi loa no ke kaiapuni a me ka hana.
Hoʻomaopopo honua:ʻO nā palapala hōʻoia e like me API 5L a me ISO 9001 e hōʻoia hou i ko lākou kūpono no nā papahana aila a me ke kinoea honua.
5Kūpaʻa i ka Hoʻomau a me ka Hana ʻŌmaʻomaʻo
Nā Hale Hana ʻŌmaʻomaʻo:Ua kapa ʻia ʻekolu o kāna mau kahua hana he "National Green Factories", me Jiangsu Youfa Pipe Co., Ltd. e loaʻa ana i ka inoa "Green Factory" i ka makahiki 2024 no kāna mau ʻōnaehana hana hou ʻana i ka wai ʻino a me ka hoʻemi ʻana i nā hoʻokuʻu kalapona.
Nā Hana Hana Maʻemaʻe:Ua hoʻomaikaʻi nā hoʻopukapuka kālā i ʻoi aku ma mua o RMB 22 miliona i ka makahiki 2023 i ka hoʻokele ʻōpala a me ka pono o ka ikehu, e hōʻemi ana i ka hoʻokuʻu ʻana o ka noe waikawa a me ka hana ʻana o nā ʻōpala weliweli.
