Chitoliro chachitsulo cholumikizidwa ndi ERW: chitoliro cholumikizidwa ndi mphamvu zambiri, chopangidwa ndi mbale yachitsulo yozunguliridwa ndi moto, kudzera mu kupanga kosalekeza, kupindika, kuwotcherera, kutentha, kukula, kuwongola, kudula ndi njira zina.
Makhalidwe: Poyerekeza ndi chitoliro chachitsulo cholumikizidwa ndi msoko wozungulira, chili ndi ubwino wolondola kwambiri, makulidwe ofanana a khoma, ubwino wabwino pamwamba komanso kukana kuthamanga kwambiri. Koma vuto lake ndilakuti chingagwiritsidwe ntchito popanga mapaipi ang'onoang'ono okhala ndi makoma ochepa. Amagwiritsidwa ntchito kwambiri mu gasi wa m'mizinda, mayendedwe amafuta osakonzedwa ndi zina.
Chitoliro chachitsulo cholumikizidwa ndi arc chozungulira: chitoliro chachitsulo cholumikizidwa ndi arc chozungulira. Pochita zozungulira, ngodya yopangira imapangidwa mozungulira, kenako njira yolumikizira imachitika pambuyo pozungulira. Chomaliza chimakhala ndi cholumikizira chozungulira.
Zinthu Zake: Ubwino wake ndi wakuti mapaipi achitsulo okhala ndi mawonekedwe ofanana komanso mainchesi osiyanasiyana amatha kupangidwa, zinthu zopangira zimakhala zambiri, ndipo weld imatha kupewa kupsinjika kwakukulu ndikupeza kupsinjika kwabwino; Zoyipa zake ndi kukula koyipa kwa geometry, kutalika kwa weld yayitali kuposa chitoliro chachitsulo cholunjika, ndipo zolakwika zolumikizira monga ming'alu, mabowo a mpweya ndi slag zimachitika nthawi ndi nthawi. Kupsinjika kwa weld kumakhala mu mkhalidwe wa kupsinjika kwa tensile. Malinga ndi Code for Design of General Long-distance Oil and Gas Pipelines, weld yozungulira ya arc ingagwiritsidwe ntchito kokha m'madera a Class 3 ndi Class 4.
Chitoliro chachitsulo cholumikizidwa ndi arc longitudinal: chitoliro chachitsulo cholumikizidwa ndi arc longitudinal, njira yopangira: choyamba pindani mbale yachitsulo mu chubu chokhala ndi nkhungu kapena makina opangira, kenako pindani arc longitudinal kawiri.
Zinthu Zake: Chogulitsachi chili ndi ubwino wa kukula kwake kwakukulu, kulimba kwake kwakukulu, kusungunuka bwino, kufanana kwake bwino komanso kufupika kwake. Pomanga mapaipi amafuta ndi gasi akutali, mapaipi owotcherera a arc omwe amalowa pansi pa nthaka kwa nthawi yayitali amafunika. Malinga ndi muyezo wa API 5L, ndi mtundu wokhawo wa mapaipi achitsulo omwe amasankhidwa m'malo ozizira, m'nyanja ndi m'mizinda yokhala ndi anthu ambiri.
Ubwino wa chitoliro chachitsulo chopanda msoko
Khoma lokhuthala ndi makulidwe.
Sili ndi chotchingira. Kawirikawiri chimaonedwa kuti chili ndi mphamvu yabwino komanso chimateteza dzimbiri.
Mapaipi opanda msoko amakhala ndi mawonekedwe ozungulira bwino kapena ozungulira bwino.
Kodi mungasankhe bwanji mapaipi achitsulo opindika kapena osapindika?
Ngakhale kuti chitoliro cholumikizidwa chili ndi ubwino wambiri, chitoliro chosasunthika chimakhala chabwino kuposa chitoliro cholumikizidwa, makamaka m'malo ovuta, chifukwa chili ndi mphamvu zambiri, kuthamanga kwambiri komanso kukana dzimbiri bwino.
Malinga ndi momwe ntchitoyo ikugwiritsidwira ntchito komanso mtengo wake, sankhani mtundu womwe uli bwino.
Malinga ndi zofunikira pa ntchito, mapaipi osasoka komanso olumikizidwa amatha kupangidwa.
Kugwiritsa ntchito mosiyanasiyana kwa chitoliro chopanda msoko ndi chitoliro cholumikizidwa
Chitoliro chachitsulo chosokedwa: chitoliro chosokedwa chimagwiritsidwa ntchito makamaka mu uinjiniya wa madzi, makampani opanga petrochemical, makampani opanga mankhwala, makampani opanga magetsi, ulimi wothirira ndi zomangamanga za m'mizinda. Mayendedwe amadzimadzi: madzi ndi ngalande zotulutsira madzi. Amagwiritsidwa ntchito poyendetsa gasi lachilengedwe: gasi lachilengedwe, nthunzi, gasi wamafuta osungunuka. Kapangidwe: mapaipi omangira, milatho, madoko, misewu, mapaipi omangira nyumba, ndi zina zotero.
Chitoliro chachitsulo chopanda msoko: Chitoliro chachitsulo chopanda msoko chili ndi gawo lopanda kanthu ndipo chimagwiritsidwa ntchito kwambiri kunyamula madzi, monga mafuta, gasi wachilengedwe, gasi wachilengedwe ndi madzi, ndi zinthu zina zolimba. Poyerekeza ndi chitsulo cholimba monga chitsulo chozungulira, chitoliro chachitsulo chimakhala chopepuka chifukwa cha mphamvu yofanana yopindika ndi yopotoka, kotero ndi chitsulo chotsika mtengo.
Ngati mukuganiza zogula CHIPAI CHOSASUNGA, CHIPAI CHOPANGIDWA CHA ERW, CHIPAI CHOPANGIDWA CHA SSAW KAPENA CHIPAI CHOPANGIDWA CHA LSAW, onani njira zomwe JINDALAI ili nazo ndipo ganizirani kulumikizana ndi gulu lathu kuti mudziwe zambiri. Tikupatsani yankho labwino kwambiri pa ntchito yanu.
