Bambanci tsakanin girman SC da DN na galvanized karfe bututu:

1.SC gabaɗaya yana nufin bututun ƙarfe na welded, harshen KARFE CONDUIT, gajeriyar hanya ce ga kayan.

2. DN yana nufin ƙananan diamita na galvanized karfe bututu , wanda shine alamar diamita na bututu.

3. Galvanized karfe bututu an raba zuwa sanyi-galvanized karfe bututu da zafi-tsoma galvanized karfe bututu.An dakatar da bututun karfe mai sanyi, kuma jihar ta tallata na biyun don amfani na wucin gadi.A cikin shekarun 1960 da 1970, kasashen da suka ci gaba a duniya sun fara samar da sabbin nau'ikan bututu da kuma hana bututun galvanized.Ma’aikatar gine-gine da wasu ma’aikatu da kwamitoci hudu sun kuma fitar da takarda inda suka fayyace cewa za a dakatar da bututun mai a matsayin bututun samar da ruwa daga shekarar 2000. Ba kasafai ake amfani da bututun mai a cikin bututun ruwan sanyi na sabon wurin zama.Bututun ruwan zafi a wasu al'ummomi suna amfani da bututun da aka yi amfani da su.Ana amfani da bututun ƙarfe mai zafi mai zafi a cikin kariyar wuta, wutar lantarki da manyan hanyoyi.

Tasirin aiki

(1) Carbon;mafi girman abun ciki na carbon, mafi girman taurin karfe, amma mafi munin filastik da taurinsa.

(2) Sulfur;kazanta ce mai cutarwa a cikin karfe.Lokacin da karfe tare da babban abun ciki na sulfur yana fuskantar aiki na matsa lamba a babban zafin jiki, yana da sauƙi ya zama raguwa kuma yawanci ana kiransa zafi mai zafi.

(3) Phosphorus;zai iya rage yawan filastik da taurin karfe, musamman a yanayin zafi mara kyau, ana kiran wannan lamarin sanyi brittleness.A cikin ƙarfe mai inganci, sulfur da phosphorus yakamata a sarrafa su sosai.Duk da haka, daga wani ra'ayi, haɗakar da sulfur mafi girma da phosphorus a cikin ƙananan ƙarfe na carbon zai iya sauƙaƙe yanke, wanda ke da amfani don inganta kayan aikin karfe.

(4) Manganese;zai iya inganta ƙarfin ƙarfe, zai iya raunana kuma ya kawar da mummunan tasirin sulfur, kuma zai iya inganta ƙarfin ƙarfe.High gami karfe (high manganese karfe) tare da babban manganese abun ciki yana da kyau lalacewa juriya.Da sauran kaddarorin jiki.

(5) Siliki;zai iya ƙara taurin karfe, amma filastik da taurin suna raguwa.Karfe da aka yi amfani da shi wajen injiniyan lantarki yana ƙunshe da wani adadin siliki, wanda zai iya inganta halayen maganadisu mai laushi.

(6) Tungsten;zai iya inganta taurin ja da ƙarfin zafi na karfe, kuma zai iya inganta juriya na lalacewa na karfe.

(7) Chromium;iya inganta hardenability da sa juriya na karfe, kuma zai iya inganta lalata juriya da hadawan abu da iskar shaka juriya na karfe.

Don juriya na lalata gabaɗaya, bututun ƙarfe na gaba ɗaya (baƙar fata) suna galvanized.Galvanized karfe bututu an raba zuwa zafi-tsoma galvanizing da lantarki karfe tutiya.Zazzafar galvanized galvanized Layer mai zafi yana da kauri, kuma farashin electro-galvanizing ba shi da yawa, don haka akwai bututun ƙarfe na galvanized.
