style="font-size:20px;">首先彎頭是用于管道拐彎處的一種管件，在管道系統(tǒng)應(yīng)用的全部管件中，占80%以上的比例，是十分重要的管件，彎頭<a href="http://www.349you.cn">推制機(jī)</a>則是制作彎頭的機(jī)械設(shè)備，通過高溫推制，或液壓冷推制彎頭的彎頭機(jī)械設(shè)備。主要有冷推彎頭機(jī)，中頻感應(yīng)加熱彎頭機(jī)（主要動力為液壓油缸）?？蛻艨梢愿鶕?jù)自己的需要選擇。如您所需要的是不銹鋼彎頭，請選擇冷推<a href="http://www.349you.cn">彎頭機(jī)</a>。若所需為碳鋼或合金鋼彎頭，則是中頻加熱彎頭機(jī)。</span></div> <div> <span style="font-size:20px;">第二，彎頭推制機(jī)屬于非標(biāo)產(chǎn)品，沒有限定的規(guī)格大小和型號，可以根據(jù)客戶的需要訂做。</span></div> <div> <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(hù)氣體來解決內(nèi)部焊縫的高溫氧化問題。</span></div> <div> <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----在彎頭機(jī)上將加熱過的管坯用模具進(jìn)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></div> <div> <span style="font-size:20px;">我公司除了生產(chǎn)<a href="http://www.349you.cn">彎頭機(jī)</a>，還生產(chǎn)三通機(jī)、中頻彎管機(jī)、彎管機(jī)、彎頭機(jī)等管件設(shè)備。</span></div> <div id="2c8e2vd" class="float_c
