Mipope yachitsulo imabwera m'njira zosiyanasiyana komanso zazikulu.Chitoliro chosasunthika ndi njira yopanda weld, yopangidwa ndi chitsulo chosapanga dzimbiri.Pankhani yowotcherera mapaipi achitsulo, pali njira zitatu: ERW, LSAW ndi SSAW.
Mapaipi a ERW amapangidwa ndi mbale zachitsulo zomangika.LSAW chitoliro chopangidwa ndi longitudinal kumizidwa arc welded zitsulo mbale.Chitoliro cha SSAW chimapangidwa ndi mbale yachitsulo yozungulira yomwe ili pansi pamadzi.
Tiyeni tiwone bwinobwino mtundu uliwonse wa chitoliro, yerekezerani kusiyana kwawo, ndi momwe tingagwiritsire ntchito kufotokozera kolondola kuti tiyitanitse.
Chubu chachitsulo chosasokonekera
Chubu chopanda msoko chimapangidwa ndi chitsulo chosapanga dzimbiri, chomwe chimatenthedwa ndikubowoleredwa kuti chikhale chozungulira chozungulira.Chifukwa chitoliro chopanda msoko chilibe malo owotcherera, chimaonedwa kuti ndi champhamvu kuposa chitoliro chowotcherera komanso chosachita dzimbiri, kukokoloka komanso kulephera kwathunthu.
Komabe, mtengo pa tani imodzi ya chitoliro chopanda msoko ndi 25-40% kuposa chitoliro cha ERW.Kukula kwa chitoliro chosasunthika kumayambira 1/8 inchi mpaka 36 inchi.
Kukaniza kuwotcherera (RW) chitoliro
ERW (kukaniza kuwotcherera) zitsulo chitoliro aumbike ndi anagubuduza zitsulo mu chitoliro ndi kulumikiza malekezero awiri ndi maelekitirodi awiri mkuwa.Ma elekitirodi awa ali ndi mawonekedwe a disc ndipo amazungulira momwe zinthu zimadutsa pakati pawo.Izi zimathandiza elekitirodi kukhalabe kukhudzana mosalekeza ndi zinthu kwa nthawi yaitali mosalekeza kuwotcherera.Kupita patsogolo kwaukadaulo wowotcherera kukupitilizabe kukonza izi.
Chitoliro cha ERW ndi cholowa m'malo mwachuma komanso chothandiza cha chitoliro chachitsulo chosasinthika, chomwe chimakhala cholimba kuposa chitoliro cha SAW.Poyerekeza ndi zosungunulira ndondomeko ntchito kumizidwa arc welded chitoliro, zilema nawonso n'zokayikitsa kuti zichitike, ndi kuwotcherera kuwotcherera zilema mosavuta wapezeka ndi akupanga kusinkhasinkha kapena masomphenya.
Kutalika kwa chitoliro cha ERW kumayambira mainchesi (15 mm) mpaka mainchesi 24 (21.34 mm).
Chitoliro cholowetsedwa cha arc
LSAW (wowotcherera msoko) ndi SSAW (spiral seam welding) ndi mitundu yosiyanasiyana ya chitoliro chomizidwa cha arc.Njira yowotcherera ya arc yomwe ili m'madzi imapanga kachulukidwe kakang'ono kakali pano kuti tipewe kutentha kwachangu kwa gawo la flux ndikukhazikika mdera lakuwotcherera.
Kusiyana kwakukulu pakati pa mapaipi a LSAW ndi SSAW ndi njira yowotcherera, yomwe idzakhudza mphamvu yonyamula mphamvu komanso kumasuka kwa kupanga.LSAW imagwiritsidwa ntchito pamagetsi apakati mpaka magetsi apamwamba, ndipo SSAW imagwiritsidwa ntchito pamagetsi otsika.Mapaipi a LSAW ndi okwera mtengo kuposa mapaipi a SSAW.
Longitudinal kumizidwa arc welded chitoliro
LSAW chitoliro amapangidwa ndi otentha adagulung'undisa koyilo zitsulo nkhungu mu yamphamvu ndi kulumikiza malekezero awiri pamodzi ndi kuwotcherera liniya.Izi zimapanga chitoliro chowotchedwa kotalika.Mapaipiwa amagwiritsidwa ntchito kwambiri pamapaipi otumizira mtunda wautali amafuta, gasi, malasha amadzimadzi, ma hydrocarbon, ndi zina zambiri.
Pali mitundu iwiri ya mapaipi a LSAW: msoko umodzi wautali ndi seam iwiri (DSAW).Chitoliro chachitsulo cha LSAW chimapikisana ndi chitoliro chachitsulo chosasinthika ndi chitoliro chachitsulo cha 16 mpaka 24 inchi ERW.M'makampani amafuta ndi gasi, mapaipi akulu akulu a API 5L LSAW amagwiritsidwa ntchito mtunda wautali komanso woyendetsa bwino wa ma hydrocarbon.
Kutalika kwa chitoliro cha LAW nthawi zambiri kumakhala pakati pa mainchesi 16 ndi mainchesi 60 (406 mm ndi 1500 mm).
Zosasunthika - zotsalira zankhondo zophulika - kuwotcherera kwakutali kwa arc - kuwotcherera kwa arc ozungulira - mapaipi - kuwotcherera kwa arc kozungulira
Mtengo wa SSAW
Chitoliro chachitsulo cha SSAW chimapangidwa ndi kugubuduza ndi kuwotcherera zitsulo mumayendedwe ozungulira kapena ozungulira kuti weld ikhale yozungulira.Njira yowotcherera yozungulira imapangitsa kuti zitheke kupanga zinthu zazikuluzikulu.Mapaipi achitsulo ozungulira amagwiritsidwa ntchito makamaka potengera kutsika kwamadzimadzi, monga mapaipi pamapulatifomu akunyanja, malo opangira mafuta a petrochemical kapena mabwalo a zombo, komanso nyumba zapagulu ndi milu.
Kutalika kwa chitoliro cha SSAW nthawi zambiri kumakhala mainchesi 20 mpaka 100 (406 mm mpaka 25040 mm).
Momwe mungayitanitsa mapaipi achitsulo a polojekiti yanu
Mukayitanitsa mapaipi achitsulo, pali miyeso iwiri yofunika: kukula kwa chitoliro (NPS) ndi makulidwe a khoma (ndandanda).Kwa mipope yosakwana mainchesi 4, kutalika kwa chitoliro kungakhale kwachisawawa (SRL) mamita 5-7, kapena mapaipi oposa mainchesi 4, kutalika kwa chitoliro kungakhale kawiri mwachisawawa (DRL) 11-13 mamita.Kutalika kwachizolowezi kulipo kwa mapaipi aatali.Mapeto a chitoliro amatha kukhala bevel (kukhala), ndege (pe), ulusi (THD) ulusi ndi kulumikizana (T&C) kapena poyambira.
Chidule cha tsatanetsatane wa dongosolo:
Mtundu (wopanda msoko kapena welded)
Kukula kwapaipi mwadzina
Ndandanda
Mtundu womaliza
Gawo lazinthu
Kuchuluka mu mita kapena mapazi kapena matani.
Ngati mukuganiza zogula PIPE YOPHUNZITSIRA, ERW PIPE, SSAW PIPE KAPENA LSAW PIPE, onani zomwe JINDALAI ali nazo kwa inu ndipo lingalirani kulumikizana ndi gulu lathu kuti mudziwe zambiri.Tidzakupatsani yankho labwino kwambiri la polojekiti yanu.
Lumikizanani nafe tsopano!
