怎樣區分無縫鋼管(guan)的優劣

1、好(hao)的無縫鋼管的成分平均，冷剪機的噸位高(gao)，切頭端面平滑而(er)劃(hua)一，而(er)偽(wei)劣(lie)材(cai)由于材(cai)質差，切頭端面常常會有掉肉(rou)的現(xian)象，即(ji)凹(ao)凸(tu)不平，并且無金屬光澤。而(er)且由于偽(wei)劣(lie)材(cai)廠家產品切頭少，頭尾會呈現(xian)大耳子。

2、偽劣無(wu)縫(feng)鋼(gang)管(guan)無(wu)金屬光澤，呈淡紅色或相似生鐵的(de)(de)顏色，緣由有(you)兩點它(ta)的(de)(de)坯(pi)料是(shi)土坯(pi)偽劣材軋制的(de)(de)溫(wen)度不規(gui)范(fan)，他們的(de)(de)鋼(gang)溫(wen)是(shi)經過目測的(de)(de)，這樣無(wu)法按(an)規(gui)則的(de)(de)奧氏體區(qu)域停(ting)止軋制，厚(hou)壁(bi)無(wu)縫(feng)管(guan)的(de)(de)性能自(zi)然就(jiu)無(wu)法達標。

3、偽(wei)劣無(wu)縫鋼(gang)管材質(zhi)含雜質(zhi)多，鋼(gang)的(de)密度偏小(xiao)，而且尺寸(cun)超(chao)差(cha)嚴重，所以在(zai)沒有游標卡尺的(de)狀況(kuang)下，能夠對它停止稱(cheng)量核(he)對。

4、偽劣無(wu)縫鋼(gang)管(guan)的橫截面呈橢圓(yuan)形，緣由(you)是(shi)廠家為了節(jie)約資料，廢品輥前二(er)道的壓下(xia)量偏(pian)大，這種(zhong)螺紋鋼(gang)的強度(du)大大公開降，而(er)且也(ye)不契合螺紋鋼(gang)外形尺(chi)寸的規(gui)范。

5、偽(wei)(wei)劣無縫(feng)鋼管外(wai)表易(yi)產生(sheng)(sheng)結疤。緣由有兩點：①偽(wei)(wei)劣無縫(feng)鋼管材(cai)質不(bu)平均(jun)，雜質多。②偽(wei)(wei)劣材(cai)廠家(jia)導衛設備粗陋(lou)，容易(yi)粘鋼，這些雜質咬人(ren)軋(ya)輥后易(yi)產生(sheng)(sheng)結疤。

6、偽(wei)劣材外表易產生(sheng)(sheng)裂紋，緣由是它(ta)的(de)坯(pi)料是土坯(pi)，土坯(pi)氣孔多(duo)，土坯(pi)在冷 卻的(de)過(guo)程中由于遭到(dao)熱(re)應力的(de)作用，產生(sheng)(sheng)裂痕，經過(guo)軋(ya)制后(hou)就有(you)裂紋。
