3087無縫鋼管按照用途分為化肥設備用高壓3087無縫鋼管;地質磚探用3087無縫鋼管。

　　3087無縫鋼管(guan)的(de)化(hua)學成分(fen)有碳C、硅Si、錳Mn、硫S、磷P、鉻Cr。磁(ci)(ci)偏(pian)吹(chui)的(de)形成是管(guan)金(jin)屬中(zhong)存在剩磁(ci)(ci)的(de)結果。通常(chang)，將(jiang)剩磁(ci)(ci)分(fen)為感應磁(ci)(ci)性(xing)(xing)和工(gong)藝(yi)磁(ci)(ci)性(xing)(xing)兩種。感應磁(ci)(ci)性(xing)(xing)常(chang)產生(sheng)(sheng)在工(gong)廠制(zhi)管(guan)的(de)環節(jie)中(zhong)，如(ru)：金(jin)屬熔煉、采用(yong)(yong)(yong)電(dian)(dian)磁(ci)(ci)起(qi)重機進行(xing)裝卸、鋼管(guan)在強磁(ci)(ci)場(chang)中(zhong)停置(zhi)、用(yong)(yong)(yong)磁(ci)(ci)化(hua)法完(wan)成無損巡查、鋼管(guan)接(jie)近強力供電(dian)(dian)線(xian)(xian)放置(zhi)等等。工(gong)藝(yi)磁(ci)(ci)性(xing)(xing)常(chang)產生(sheng)(sheng)在進行(xing)裝配焊(han)接(jie)作業及(ji)采用(yong)(yong)(yong)磁(ci)(ci)性(xing)(xing)夾持(chi)器、夾具與用(yong)(yong)(yong)直流電(dian)(dian)焊(han)接(jie)管(guan)道時，如(ru)：長時間(jian)接(jie)觸(chu)與直流電(dian)(dian)源相(xiang)連(lian)的(de)電(dian)(dian)導(dao)線(xian)(xian)，導(dao)線(xian)(xian)裸露段或(huo)者(zhe)電(dian)(dian)焊(han)鉗與管(guan)子(zi)的(de)短路等。

　　焊接帶(dai)磁性(xing)鋼管時，經常會(hui)看到電(dian)弧引燃的破壞、在磁場(定(ding)義:傳遞實(shi)物間磁力作用的場)中電(dian)弧的偏(pian)離、液體金屬和渣熔(rong)融體從焊接熔(rong)池中的濺(jian)出。

　　為了穩定(ding)焊(han)接(jie)過程，改善焊(han)接(jie)接(jie)頭質量，被磁(ci)化了的(de)鋼管在焊(han)接(jie)前要進行消磁(ci)。
