鋼材價(jià)格步入下降通道，已弱勢下跌4個(gè)多月。截止2013年7月26日，鋼材價(jià)格指數(shù)降到，低于年初。鋼鐵工業(yè)協(xié)會(huì)重點(diǎn)統(tǒng)計(jì)的八個(gè)鋼材品種價(jià)格比年初均有不同程度的下降，平均跌幅。分品種來看。占我國鋼材產(chǎn)量比重較大的建筑用線材、螺紋鋼價(jià)格跌幅分別達(dá)，中厚板和熱軋卷板價(jià)格跌幅分別達(dá)。(三)鋼材出口增長較快。國內(nèi)鋼材市場供需失衡刺激企業(yè)出口。1-6月，我國累計(jì)出口鋼材3069萬噸，同比增長，下降，進(jìn)口鋼坯和鋼錠32萬噸，增長50%。將坯材折合粗鋼，累計(jì)凈出口2506萬噸，同比增長，占我國粗鋼產(chǎn)量的。從出口價(jià)格看，1-6月出口棒線材均價(jià)，同比下降18%;板材，同比下降。(四)鋼廠及社會(huì)庫存高位運(yùn)行。市場供需矛盾向流通領(lǐng)域蔓延，國內(nèi)鋼材庫存延續(xù)上年末增長態(tài)勢。3月15日達(dá)到歷史高的2252萬噸，比上年高點(diǎn)增加351萬噸，其中建筑鋼材庫存1432萬噸，占庫存總量的。之后，隨著季節(jié)性消費(fèi)增加，庫存逐漸回落，7月26日降至1540萬噸。市場供大于求也推高鋼廠庫存，3月中旬重點(diǎn)企業(yè)鋼材庫存創(chuàng)歷史記錄，達(dá)到1451萬噸，同比增長，6月下旬降至1268萬噸，仍比年初增長，比2012年同期增長。(五)鋼廠盈利水平逐月下滑。2013年上半年，冶金行業(yè)實(shí)現(xiàn)利潤，同比增長。安徽不銹鋼無縫管鋼管公司生產(chǎn)的名亮**304等質(zhì)量不銹鋼管，廣泛應(yīng)用于世界各地市政工程、樓梯扶手，護(hù)欄等。</p><div

A、按GB14975-2002《不銹鋼無縫鋼管》規(guī)定，鋼管通常長度(不定尺)熱軋鋼管1.5～10m，熱擠壓鋼管等于和大于1m。冷拔(軋)鋼管壁厚0.5～1.0mm者，1.0～7m；壁厚大于1.0mm者，1.5～8m。 </p> <p> B、熱軋(熱擠壓)鋼管的直徑54～480mm共45種；壁厚4.5～45mm共36種。冷拔(軋)鋼管的直徑6～200mm共65種；壁厚0.5～21mm共39種。 </p> <p> C、鋼管內(nèi)外表面不得有裂縫、折疊、龜裂、裂紋、軋折、離層和結(jié)疤缺點(diǎn)存在，這些缺點(diǎn)應(yīng)完全***掉(供機(jī)械加工用管除外)，***后不得使壁厚和外徑超過負(fù)偏差。凡不超過允許負(fù)偏差的其他輕微表面缺點(diǎn)可不***。 </p> <p> D、直道允許深度。熱軋、熱擠壓鋼管、直徑小于和等于140mm的不大于公稱壁厚的5%，比較大深度不大于0.5mm；冷拔(軋)鋼管不大于公稱壁厚的4%，比較大深度不大于0.3mm。 </p> <p> E、鋼管兩端應(yīng)切成直角，并***毛刺。 </p> <p> <br /> </p><p> 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(huì)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(huì)出現(xiàn)大耳子。 </p> <p> <br /> 康復(fù)不銹鋼管固有的耐蝕功能。</p><div

不銹鋼管是一種經(jīng)濟(jì)的斷面鋼材，是鋼鐵工業(yè)中的一項(xiàng)重要產(chǎn)品，可***用于生活裝飾和工業(yè)，市面上很多人用于制作樓梯扶手、護(hù)窗、欄桿、家具等。常見的有201和304兩種材質(zhì)。占全部鋼材總量的8%一16%左右，它在國民經(jīng)濟(jì)中的應(yīng)用范圍極為***。不銹鋼按生產(chǎn)方式分為無縫管和焊管兩大類，那么兩者有什么區(qū)別？ </p> <p> 性能和價(jià)格上的區(qū)別 </p> <p> <br /> </p> <p> 無縫管在抗腐蝕性以及承壓耐高溫等性能上要比焊管高得多。隨著焊管制作工藝的提高，力學(xué)性能和機(jī)械性能上也慢慢向無縫管靠近。無縫管在制作工藝上比較復(fù)雜，它的價(jià)格比焊管要貴。 </p> <p> 基于不銹鋼無縫管和焊管的特點(diǎn)和區(qū)別，應(yīng)用時(shí)要合理的進(jìn)行選擇，達(dá)到經(jīng)濟(jì)、美觀和可靠的效果： </p> <p> （1）用做裝飾管、制品管、道具管時(shí)，一般要求有良好的表面效果，通常選用不銹鋼焊管； </p> <p> （2）對(duì)于一般較低壓力的流體輸送，如輸送水、油、煤氣、空氣以及取暖熱水或蒸汽等低壓系統(tǒng)，通常選用不銹鋼焊管； </p> <p> （3）對(duì)于用在工業(yè)工程及大型設(shè)備上輸送流體的管道，以及電站、核電站鍋爐上要求耐高溫高壓、**度的輸送流體管道，則應(yīng)選用不銹鋼無縫管道； </p> <p> （4）不銹鋼焊管一般用于0.8MPa以下的液體輸送，無縫管可用于承受0.8MPa以上的液體輸送。如果壓力要求不高，使用焊管會(huì)更經(jīng)濟(jì)些。 </p> <p> <br /> 對(duì)于用在工業(yè)工程及大型設(shè)備上輸送要求耐高溫高壓、**度的輸送流體管道，則應(yīng)選用不銹鋼無縫管道。安徽不銹鋼無縫管鋼管</p><p style="text-indent:25px">選購時(shí)應(yīng)選擇經(jīng)質(zhì)量技術(shù)監(jiān)督局評(píng)定的***產(chǎn)品，客戶中有長時(shí)間使用見證和良好口碑是**直接有效的選購方法。安徽不銹鋼無縫管鋼管</p><p> 很多客戶在挑選材料的時(shí)候都面臨非常多的問題，看著市面上參差不齊的價(jià)格以及相關(guān)問題都得不到**終的解決辦法，江蘇進(jìn)百洪再這里給大家分享一些技巧，以至于再后期挑選成品的時(shí)候提高產(chǎn)品性價(jià)比； </p> <p> <br /> </p> <p> 二、軋制管中經(jīng)常會(huì)出現(xiàn)內(nèi)重皮、麻點(diǎn)、和軋制青線，一般情況下這些無法避免，也基本不影響使用，但在選購時(shí)一定要選擇盡量少的，特別是檢查內(nèi)表面。 </p> <p> 三、選購時(shí)應(yīng)選擇經(jīng)質(zhì)量技術(shù)監(jiān)督局評(píng)定的***產(chǎn)品。在客戶中有長時(shí)間使用見證和良好口碑是**直接有效的選購方法。 </p> <p> 四、觀看外表面和管內(nèi)壁的顏色是否光亮平滑、厚度是否均勻或有粗糙現(xiàn)象。一般焊管此項(xiàng)基本不用檢查，而不銹鋼無縫管是采用冷拔或熱軋方式生產(chǎn)的，在生產(chǎn)過程中操作不當(dāng)容易產(chǎn)生厚度不均勻、管面有裂紋等現(xiàn)象，而表面粗糙一般是無縫管未進(jìn)行拋光處理，若對(duì)外觀無特別要求不影響使用。 </p> <p> 五、在挑選不銹鋼無縫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316以上材質(zhì)。 </p> <p> <br /> </p> <p>
