Bututun ƙarfe ya zo da nau'i da yawa da yawa. Bututu maras nauyi zaɓi ne mara walda, wanda aka yi da bututun ƙarfe mai rami. Idan ana maganar bututun ƙarfe na walda, akwai zaɓuɓɓuka guda uku: ERW, LSAW da SSAW.
Ana yin bututun ERW da faranti na welded karfe. An yi bututun LSAW da farantin karfe mai walƙiya a tsaye. An yi bututun SSAW da farantin karfe mai jujjuyawar baka mai karkata.
Bari mu dubi kowane nau'in bututu, kwatanta bambance-bambancen su, da yadda za a yi amfani da bayanin daidai don yin oda.
Bututun ƙarfe mara nauyi
An yi bututun da ba shi da sumul da billet ɗin bakin karfe, wanda aka yi zafi da huɗa don samar da sashin da'ira. Saboda bututu maras sumul ba shi da wurin waldawa, ana ganin ya fi ƙarfin bututun walda kuma ba shi da lahani ga lalata, zaizayar ƙasa da gazawar gaba ɗaya.
Duk da haka, farashin kowace tan na bututu maras sumul yana da 25-40% sama da na bututun ERW. Girman bututun ƙarfe mara ƙarfi ya bambanta daga 1/8 inch zuwa 36 inch.
Resistance walda (ERW) bututu
ERW (resistance walda) karfe bututu ana samuwa ta hanyar mirgina karfe cikin bututu da kuma haɗa iyakar biyu tare da na'urorin jan ƙarfe guda biyu. Waɗannan na'urorin lantarki suna da sifar diski kuma suna juyawa yayin da kayan ke wucewa a tsakanin su. Wannan yana ba da damar lantarki don ci gaba da hulɗa tare da kayan na dogon lokaci na ci gaba da walda. Ci gaban fasahar walda yana ci gaba da inganta wannan tsari.
ERW bututu ne mai tattalin arziki da inganci maimakon sumul karfe bututu, wanda shi ne mafi m fiye da SAW bututu. Idan aka kwatanta da sauran ƙarfi tsari da aka yi amfani da submerged baka welded bututu, lahani kuma da wuya su faru, kuma madaidaiciya weld lahani za a iya samun sauƙin gano ta ultrasonic tunani ko hangen nesa.
Diamita na bututun ERW daga inci (15 mm) zuwa inci 24 (21.34 mm).
Submerged baka welded bututu
LSAW (daidaitaccen walƙiya) da SSAW (spiral seam waldi) bambance-bambancen bututun da aka ƙera baka. Tsarin waldawar baka mai nutsewa yana haifar da babban yawan halin yanzu don hana saurin zubar da zafi na juzu'in juzu'i da kuma mai da hankali a cikin yankin walda.
Babban bambanci tsakanin bututun LSAW da SSAW shine jagorancin walda, wanda zai shafi ƙarfin ɗaukar nauyi da sauƙi na masana'anta. Ana amfani da LSAW don aikace-aikacen matsakaici-ƙarfin wutar lantarki zuwa babban ƙarfin lantarki, kuma ana amfani da SSAW don aikace-aikacen ƙananan ƙarfin lantarki. Bututun LSAW sun fi bututun SSAW tsada.
Dogayen nutsewar baka welded bututu
Ana yin bututun LSAW ta hanyar yin gyare-gyaren ƙarfe mai zafi mai zafi zuwa silinda da haɗa iyakar biyu tare ta hanyar walda ta layi. Wannan yana haifar da bututu mai welded mai tsayi. Ana amfani da waɗannan bututun don isar da bututun mai na nesa, iskar gas, kwal ruwa, hydrocarbons, da sauransu.
Akwai nau'ikan bututun LSAW guda biyu: kabu mai tsayi guda ɗaya da kabu biyu (DSAW). LSAW karfe bututu gasa tare da sumul karfe bututu da 16 zuwa 24 inch ERW karfe bututu. A cikin masana'antar mai da iskar gas, ana amfani da manyan bututun API 5L LSAW na diamita don tafiya mai nisa da ingantaccen sufuri na hydrocarbons.
Diamita na bututun LAW yawanci tsakanin inci 16 da inci 60 (406 mm da 1500 mm).

SSAW tube
SSAW bututun karfe yana samuwa ta hanyar birgima da waldawa karfen tsiri a karkace ko karkace alkibla don yin walda ta zama karkace. Tsarin walda mai karkace yana ba da damar kera samfuran manyan diamita. An fi amfani da bututun ƙarfe na ƙarfe don watsa ruwa mai ƙarancin ƙarfi, kamar bututun da ke cikin dandamali na teku, tsire-tsiren petrochemical ko wuraren jirage, da gine-ginen farar hula da tarawa.
Matsakaicin diamita na bututu na SSAW gabaɗaya inci 20 zuwa inci 100 (406 mm zuwa 25040 mm).
Yadda ake yin odar bututun ƙarfe don aikinku
Lokacin yin odar bututun ƙarfe, akwai maɓalli biyu masu mahimmanci: girman bututu mara kyau (NPS) da kauri na bango (jadawali). Don bututun da bai wuce inci 4 ba, tsayin bututu zai iya zama bazuwar mita ɗaya (SRL) 5-7, ko kuma na bututu fiye da inci 4, tsayin bututu zai iya zama ninki biyu (DRL) mita 11-13. Tsawon al'ada yana samuwa don dogon bututu. Ƙarshen bututu na iya zama bevel (be), jirgin sama (pe), zaren (THD) zaren da haɗa guda biyu (T&C) ko tsagi.
