Ndondomeko ya Tube 40 ndi muyezo wofanana wa makulidwe a khoma la mapaipi, womwe uli m'dongosolo la kukula kwa ANSI/ASME B36.10 (chitoliro chachitsulo cha kaboni) kapena B36.19 (chitoliro chachitsulo chosapanga dzimbiri"Ndandanda" apa ikuyimira mulingo wa makulidwe a khoma la payipi, ndipo Ndandanda 40 (yofupikitsidwa ngati Sch 40) ndiyo mulingo wogwiritsidwa ntchito kwambiri komanso wogwiritsidwa ntchito kwambiri.
Zinthu zomwe zili mu Pulogalamu ya Tube 40:
Kukhuthala kwapakati kwa khoma:chokhuthala kuposa Ndandanda 10 koma chocheperako kuposa Ndandanda 80.
Mphamvu yodalirika:imatha kupirira kupsinjika pang'ono komanso kupsinjika kwa makina.
Kufalikira kwamphamvu:Ili ndi ntchito zambiri m'mafakitale komanso m'magawo a anthu wamba.
Zipangizo zosiyanasiyana:ikhoza kukhala chitoliro chachitsulo cha kaboni, chitoliro chachitsulo chosapanga dzimbiri, kapena chitoliro chachitsulo cholimba.
Ndondomeko ya Chubu cha Chitsulo 40 Ntchito Zofala:
Njira yoperekera madzi ndi madzi otayira madzi
Chitoliro cha moto
Kuyendera gasi wachilengedwe ndi nthunzi
Mapaipi a mafakitale ndi zida zomangira makina
Nyumba ndi Zomangamanga

Ndandanda 40 ndi Kuyerekeza kwa Ndandanda Zina:
Potengera chitsanzo cha mapaipi okwana mainchesi awiri (2"), onetsani kusiyana kwa makulidwe a khoma pakati pa Ndandanda 10, 40, ndi 80:

Kodi Ubwino wa Youfa Brand Schedule 40 Carbon Pipe ndi Chiyani?
Monga wopanga wotsogola mumakampani opanga mapaipi achitsulo ku China, Youfa Group yakhazikitsa mbiri yake kudzera mu luso lopanga lolimba, ukadaulo watsopano wokonza zinthu, ziphaso zolimba zazinthu, komanso kudzipereka pakupanga zinthu zokhazikika.
1. Kuchuluka Kwambiri kwa Kupanga ndi Kukula
Youfa Group imayang'anira malo 8 opangira zinthu ku China konse (monga Tianjin, Hebei, Jiangsu, ndi Yunnan), okhala ndi mizere yopangira zinthu yoposa 300 yomwe imakwaniritsa ntchito yoposa matani 20 miliyoni a mapaipi achitsulo pachaka. Mapaipi achitsulo cha carbon a Schedule 40 a kampaniyo, omwe ndi mzere waukulu wazinthu, amapindula ndi kukula kwakukulu kumeneku, kuonetsetsa kuti mafuta, gasi, ndi zomangamanga zikupezeka bwino komanso kuti ntchito zake zikuyenda bwino.
Utsogoleri wa Msika:Youfa wakhala pamalo oyamba pa malonda a mapaipi achitsulo opangidwa ndi zitsulo ku China kwa zaka 19 motsatizana, ndipo msika wamkati uli ndi pafupifupi 35% ya mapaipi opangidwa ndi galvanized otentha.
Kufikira Padziko Lonse:Zogulitsa zimatumizidwa kumayiko opitilira 100, kuphatikiza Southeast Asia ndi Middle East, mothandizidwa ndi mapulani omwe akupitilira kukulitsa maziko opanga kunja.
2. Mafotokozedwe Okwanira ndi Kusintha
Makulidwe a m'mimba mwake:Kuyambira DN15 mpaka DN1200, zomwe zimathandiza pa ntchito zotumizira mafuta ndi gasi, chithandizo cha kapangidwe kake, ndi ntchito zapansi panthaka.
Kusintha:Zophimba zomwe mungasankhe (monga epoxy resin, polyethylene) zimathandiza kuti dzimbiri lisawonongeke m'malo ovuta monga kuboola m'mphepete mwa nyanja kapena kukonza mankhwala.
3. Kukonza Kwambiri ndi Kuwongolera Ubwino
Kupanga Zatsopano:Kampaniyo ili ndi ma patent ovomerezeka 188, kuphatikizapo makina olumikizira mapaipi odzipangira okha ndi makina ogwiritsira ntchito ma galvanizing osagwiritsa ntchito mphamvu zambiri, zomwe zimapangitsa kuti ntchito yopangira ikhale yogwira mtima komanso kuchepetsa ndalama.
CNAS Ma Lab Ovomerezeka:Ma laboratories asanu odziwika bwino mdziko lonse amachita mayeso opitilira 200 abwino, kuphatikizapo kupanikizika kwa hydrostatic, kusanthula kapangidwe ka mankhwala, ndi mayeso osawononga, kuonetsetsa kuti akutsatira miyezo ya ASTM A53, GB/T 3091, ndi miyezo ina yapadziko lonse lapansi.
Njira Yotsatirira:Chitoliro chilichonse chimapatsidwa nambala yapadera yodziwira khalidwe la moyo wonse, kulimbikitsa kuyankha mlandu ndi kudalirika.
4. Ziphaso ndi Miyezo Yotsogola pa Makampani
Satifiketi Yogulitsa Zachilengedwe Padziko Lonse:Zinthu zambiri za Youfa, kuphatikizapo mapaipi a Schedule 40, zavomerezedwa kuti ndi "Zogulitsa Zokongoletsa Zobiriwira" ndi Unduna wa Zamalonda ndi Ukadaulo wa Chidziwitso ku China, zomwe zikuwonetsa kuti ndi zabwino kwambiri pa chilengedwe komanso magwiridwe antchito.
Kuzindikiridwa Padziko Lonse:Zikalata monga API 5L ndi ISO 9001 zimatsimikiziranso kuti ndizoyenera kugwiritsa ntchito mapulojekiti apadziko lonse lapansi amafuta ndi gasi.
5Kudzipereka ku Kukhazikika ndi Kupanga Zinthu Zobiriwira
Mafakitale Obiriwira:Maziko atatu opanga ake ndi "National Green Factories", ndipo Jiangsu Youfa Pipe Co., Ltd. idalandira udindo wa "Green Factory" mu 2024 chifukwa cha njira zake zobwezeretsanso madzi otayira komanso kuchepetsa mpweya woipa wa carbon.
Njira Zopangira Zinthu Zoyera:Ndalama zomwe zinayikidwa pa ndalama zokwana RMB 22 miliyoni mu 2023 zinathandiza kuti pakhale kasamalidwe ka zinyalala komanso kugwiritsa ntchito bwino mphamvu, kuchepetsa kutulutsa kwa asidi komanso kupanga zinyalala zoopsa.
