Mafotokozedwe ndi Miyezo ya Mapaipi a Chitsulo Ozungulira Ozungulira
Mafotokozedwe:Kunja kwa mainchesi 219mm mpaka 3000mm; Kukhuthala sch40, sch80, sch160; Kutalika 5.8m, 6m, 12m kapena makonda
Magiredi:Mapaipi a SSAW amatha kupangidwa m'magiredi osiyanasiyana, kuphatikiza ma specifications a API 5L monga Giredi B, X42, X52, X60, X65, X70, ndi X80.
Miyezo:Kawirikawiri amapangidwa motsatira miyezo monga API 5L, ASTM A252, kapena zina zofunikira kutengera momwe ntchitoyo ikuyendera.
API 5L: Muyezo uwu waperekedwa ndi American Petroleum Institute ndipo umalongosola zofunikira popanga magawo awiri azinthu (PSL 1 ndi PSL 2) a mapaipi achitsulo osasenda komanso olumikizidwa kuti agwiritsidwe ntchito m'machitidwe oyendera mapaipi m'mafakitale amafuta ndi gasi.
ASTM A252: Muyezo uwu waperekedwa ndi American Society for Testing and Materials ndipo umakhudza mapaipi achitsulo ozungulira omwe ali pakhoma momwe silinda yachitsulo imagwira ntchito ngati chiwalo chonyamula katundu chokhazikika kapena ngati chipolopolo chopangira milu ya konkire yopangidwa m'malo mwake.
Chitoliro Chopangidwa ndi Chitsulo cha SSAW Spiral Welded Steel
Chophimba cha Polyethylene (3LPE) cha Zigawo Zitatu:Chophimba ichi chimakhala ndi gawo la epoxy lolumikizidwa ndi fusion, gawo lomatira, ndi gawo la polyethylene. Chimapereka kukana dzimbiri bwino ndipo nthawi zambiri chimagwiritsidwa ntchito pa mapaipi m'malo ovuta.
Chophimba cha Fusion-Bonded Epoxy (FBE):Chophimba cha FBE chimapereka kukana kwa mankhwala ndipo chimagwiritsidwa ntchito pamwamba pa nthaka komanso pansi pa nthaka.
Kukongoletsa:Njira yopangira ma galvanizing imaphatikizapo kugwiritsa ntchito chivundikiro cha zinc choteteza ku chitoliro chachitsulo kuti chikhale cholimba ndi dzimbiri. Chitoliro chachitsulo chozungulira chimamizidwa mu bafa la zinc yosungunuka, yomwe imapanga mgwirizano wachitsulo ndi chitsulo, ndikupanga chivundikiro cholimba komanso cholimba ndi dzimbiri. Kuyika ma galvanizing m'madzi otentha ndikoyenera kugwiritsidwa ntchito mkati ndi kunja ndipo kumateteza bwino dzimbiri ndi dzimbiri.
Mapulogalamu Opangira Mapaipi Opangidwa ndi Zitsulo za Carbon
Kuyendera Mafuta ndi Gasi:Amagwiritsidwa ntchito kwambiri ponyamula mafuta osakonzedwa, gasi wachilengedwe, ndi zinthu zina zamafuta pamtunda wautali.
Kugawa Madzi:Yoyenera mapaipi amadzi chifukwa cha kulimba kwawo komanso kukana dzimbiri.
Ntchito Zomangamanga:Amagwira ntchito yomanga nyumba zothandizira zomangamanga, monga milatho, nyumba, ndi mapulojekiti ena omanga nyumba.
Kuyang'anira ndi Kuwongolera Ubwino wa Mapaipi a Chitsulo cha Carbon Chozungulira
Kuyang'anira Magawo:Mapaipi amawunikidwa kuti agwirizane ndi kukula kwake, makulidwe a khoma, ndi kutalika kwake.
Kuyesa kwa Makina:Mapaipi amayesedwa kuti awone ngati ali olimba, amphamvu, otalikira, komanso olimba kuti atsimikizire kuti akukwaniritsa miyezo yofunikira.
Kuyesa Kosawononga:
Kuyesa kwa Ultrasonic (UT): Kumagwiritsidwa ntchito kuzindikira zolakwika zamkati mu msoko wothira weld.
Kuyesa kwa Madzi Osasunthika: Chitoliro chilichonse chimayesedwa kupanikizika kwa madzi osasunthika kuti chitsimikizire kuti chingathe kuthana ndi kupsinjika kogwira ntchito popanda kutuluka madzi.
Mapaipi Opangidwa ndi Zitsulo Zozungulira Zokhala ndi Mpweya Wozungulira
Tsatanetsatane wa Kulongedza: m'matumba okhala ndi ma hexagonal okhazikika panyanja odzazidwa ndi zingwe zachitsulo, Ndi zingwe ziwiri za nayiloni pa phukusi lililonse.
Tsatanetsatane wa Kutumiza: Kutengera ndi kuchuluka, nthawi zambiri mwezi umodzi.
