style="font-size:36px;">彎頭機</span></a></h3> <p> <span style="font-size:20px;">不銹鋼彎頭有什么特點？</span></p> <p> <span style="font-size:20px;">在高溫下具有很活潑的化學(xué)性能、熱導(dǎo)率小、熱容量大，在不銹鋼彎頭焊接時，管內(nèi)焊縫極易出現(xiàn)氧化和被空氣污染等問題，嚴(yán)重影響焊接質(zhì)量，為此，不銹鋼彎頭焊接時必須采用管道內(nèi)部充保護氣體來解決內(nèi)部焊縫的高溫氧化問題。</span></p> <p> <span style="font-size:20px;">目前國內(nèi)鋼制彎頭成形制造常用的加工方法有：鑄造法、沖壓壓型法、焊接法、冷熱推制法。沖壓壓型法----在<a href="http://www.gdzjsme.cn">彎頭機</a>上將加熱過的管坯用模具進行彎曲加工的方法，這種方法最早用于管彎頭彎曲加工的工藝方法，在彎頭生產(chǎn)中已獲得了廣泛應(yīng)用。但是這種方法生產(chǎn)的彎頭壁厚不均，外觀質(zhì)量差，加工大型彎頭時，模具制造成本較高。</span></p> <p> <span style="font-size:20px;">我公司除了生產(chǎn)<a href="http://www.gdzjsme.cn">彎頭機</a>，還生產(chǎn)三通機、中頻彎管機、彎管機、彎頭機等管件設(shè)備。</span></p> <div id="uooysik" class="float_c news-page fs_14"> <div id="0gksykm"
