Anan akwai mahimman bayanai game da bututun welded na karkace don canja wurin ruwa mara ƙarfi:
Girma da siffa: Za a daidaita girman jerin nau'ikan bututu masu waldaran karkace bisa ga ma'auni masu dacewa don saduwa da buƙatun aikace-aikacen daban-daban.
Bukatun fasaha: Abubuwan buƙatun fasaha don bututun welded na karkace sun haɗa da hanyoyin masana'anta, nau'ikan ƙarfe, abun da ke tattare da sinadarai, kaddarorin injin, gwajin hydrostatic, gwaji mara lalacewa, ingancin bayyanar, da sauransu.
Hanyar masana'antu: Yawancin lokaci ana amfani da ɗigon ƙarfe mai zafi don yin ɓangarorin bututu, waɗanda ake yin su a karkace a yanayin zafin daki, kuma ana yin walda ta hanyar walda ta atomatik.
Nau'in karfe: Karfe wanda ya dace da ka'idojin kasa yakamata a yi amfani da shi, kamar Q195, Q215 da Q235 karfe a GB/T 700--1988. Sauran nau'ikan karfe tare da kyakkyawan aikin walda kuma ana iya amfani da su bisa ga yarjejeniyar.
Dubawa mara lalacewa: Gyara welds na bututun ƙarfe, ƙwanƙwasa ƙwanƙarar ƙarfe da walda masu kewaye yakamata a duba su ta X-ray ko ultrasonic don tabbatar da ingancin walda.
Ingantattun bayyanar: Fannin bututun ƙarfe ya kamata ya zama santsi, kuma ba a yarda da lahani irin su fasa, tabo, folds, da sauransu. Abubuwan da ba za a iya tantance zurfin su ba ya kamata a cire su gaba ɗaya ta hanyar niƙa.
Gwajin matsin lamba na Hydrostatic: Kowane bututun karfe yakamata a yi gwajin matsa lamba na hydrostatic don tabbatar da cewa babu yabo. Ana ƙididdige matsi na gwaji kuma an ƙaddara bisa ga dabara.
Ma'auni: Samar da dubawar bututun welded na karkace don jigilar ruwa mai ƙarancin matsin lamba ya kamata su bi ka'idodin ƙasa, kamar GB/T 3091-2015, da sauransu. .
Iyakar aikace-aikacen: Ya dace da bututun jigilar ruwa mai ƙarancin ƙarfi kamar ruwa, najasa, iska, dumama tururi, da sauransu, kuma ana iya amfani da shi don sauran bututun jigilar ruwa tare da buƙatu iri ɗaya.
Takaddun shaida mai inganci: Kafin a isar da bututun welded na karkace don amfani, yakamata a samar da takardar shaida mai inganci don tabbatar da cewa ta cika buƙatun ƙa'idodi masu dacewa.
A taƙaice, an yi amfani da bututu masu waldaran karkace don safarar ruwa mai ƙarancin ƙarfi a fagen jigilar ruwa mai ƙarancin ƙarfi saboda tattalin arzikinsu da daidaitawa. Dole ne a bi ƙa'idodin ƙasa masu mahimmanci yayin ƙira da amfani don tabbatar da ingancin samfur da amincin.
