我們應(yīng)該用什么標(biāo)準(zhǔn)去評(píng)判304不銹鋼管的質(zhì)量？不銹鋼管是我們生活中常常會(huì)出現(xiàn)的東西，我們平常就可以自己去購(gòu)買，但是不是專業(yè)的人看不出他質(zhì)量的好壞，加上現(xiàn)在304不銹鋼管的種類非常多經(jīng)常挑著挑著就挑花了眼，有什么方法能判斷出304不銹鋼管的好壞呢? 一、在挑選304不銹鋼管之前需考慮到不銹鋼管的用途以及使用環(huán)境.如：裝潢用一般使用焊管,流體輸送一般用無(wú)縫管,醫(yī)療或廚房要使用衛(wèi)生級(jí)不銹鋼管,承壓使用厚壁管;一般室內(nèi)采用200系列材質(zhì)即可,室外需使用304等材質(zhì),而在酸堿性地方或沿海地區(qū)一般要使用3l6以上材質(zhì). 二、在挑選鋼管時(shí)必須確定材質(zhì)達(dá)標(biāo).以304材質(zhì)為例： l.從價(jià)格上分析,若304不銹鋼管甚至低于市場(chǎng)上30l材質(zhì)的普遍價(jià)格,要仔細(xì)辨別,很可能是其他材質(zhì)冒充; 2.認(rèn)明304不銹鋼管面上是否打鋼印材質(zhì)“304”字樣,并要索取廠家質(zhì)量證明書(shū)作為憑證; 3.可用酸性試劑測(cè)試,30秒后材質(zhì)304不變色,20l變黑色; 4.大批量購(gòu)買可抽取樣品送至**檢測(cè)中心進(jìn)行成分化驗(yàn)檢測(cè). </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p>
