假冒偽劣厚壁無縫管的鑒別方法 </p> <p> <br /> </p> <p> 6．偽劣厚壁無縫鋼管無金屬光澤，呈淡紅色或類似生鐵的顏色，原因有兩點(diǎn)二、它的坯料是土坯。2、偽劣材軋制的溫度不標(biāo)準(zhǔn)，他們的鋼溫是通過目測的，這樣無法按規(guī)定的奧氏體區(qū)域進(jìn)行軋制，厚壁無縫鋼管的性能自然就無法達(dá)標(biāo)。 </p> <p> <br /> </p> <p> 7．偽劣厚壁無縫鋼管的橫筋細(xì)而低，經(jīng)常出現(xiàn)充不滿的現(xiàn)象，原因是廠家為達(dá)到大的負(fù)公差，成品前幾道的壓下量偏大，鐵型偏小，孔型充不滿。 </p> <p> <br /> </p> <p> 8．偽劣厚壁無縫鋼管的橫截面呈橢圓形，原因是廠家為了節(jié)約材料，成品輥前二道的壓下量偏大，這種螺紋鋼的強(qiáng)度**地下降，而且也不符合螺紋鋼外形尺寸的標(biāo)準(zhǔn)。 </p> <p> <br /> </p> <p> 9．質(zhì)量厚壁無縫鋼管的成分均勻，冷剪機(jī)的噸位高，切頭端面平滑而整齊，而偽劣材由于材質(zhì)差，切頭端面常常會有掉肉的現(xiàn)象，即凹凸不平，并且無金屬光澤。而且由于偽劣材廠家產(chǎn)品切頭少，頭尾會出現(xiàn)大耳子。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img

是不是不銹鋼就一定不生銹呢？答案非常簡單，江蘇進(jìn)百洪金屬給您解答分享下，不銹鋼就是一種不容易生銹的鋼種。但不同的材質(zhì)的不銹鋼管在同一使用區(qū)域的耐銹等級不一樣，同一材質(zhì)的不銹鋼管在不同的使用區(qū)域耐銹等級也不一樣。即如果你使用的工程區(qū)域環(huán)境對不銹鋼管污染較大，要求使用高等級（SUS304,或SUS316L)的不銹鋼管，你可千萬別吝惜,別用低等級的(201)不銹鋼管。 </p> <p> <br /> </p> <p> 如果使用的區(qū)域在內(nèi)陸，不存在高污染環(huán)境，周邊空氣或環(huán)境非常好，你可以使用耐銹等級較低的不銹鋼管（201），節(jié)約不必要的金錢支出，不銹鋼畢竟是一種裝飾材料，只要不生銹，使用的效果與功能是一樣的。購買不銹鋼管不像買鋁合金，也不像買鋼材、塑鋼那么直觀易于選購,因?yàn)槟壳笆袌錾系牟讳P鋼管差別非常大，可以這么說，同樣一根長度厚度管徑重量都一樣的管，價(jià)格相差有1.5倍之多，所以不能只看管的大小與厚度，還必須了解管材的材質(zhì)。
