style="color:#003399;font-size:16px;"></span> </p> <p> 一：焊接銅管按焊接方法不同可分為電弧銅管、高頻或低頻電阻銅管、氣銅管、爐銅管、邦迪管等。 </p> <p> 電焊銅管：用于石油鉆采和機(jī)械制造業(yè)等。 </p> <p> 銅管材質(zhì)標(biāo)準(zhǔn)爐銅管：可用作水煤氣管等，大口徑直縫銅管用于高壓油氣輸送等；螺旋銅管用于油氣輸送、管樁、橋墩等。 </p> <p> 二：按焊縫形狀分類可分為直縫銅管和螺旋銅管 </p> <p> (1)直縫銅管：生產(chǎn)工藝簡(jiǎn)單，生產(chǎn)效率高，成本低，發(fā)展較快。 </p> <p> (2)螺旋銅管：強(qiáng)度一般比直縫銅管高，能用較窄的坯料生產(chǎn)管徑較大的銅管，銅管材質(zhì)標(biāo)準(zhǔn)還可以用同樣寬度的坯料生產(chǎn)管徑不同的銅管。但是與相同長(zhǎng)度的直縫管相比，焊縫長(zhǎng)度增加30~**，而且生產(chǎn)速度較低。因此，較小口徑的銅管大都采用直縫焊，大口徑銅管則大多采用螺旋焊。 </p><p> 黃銅和紫銅是兩種不同銅的存在形態(tài)。它們?cè)谌藗兊娜粘Ｉ钪泻凸I(yè)生產(chǎn)中均得到了***的應(yīng)用。了解黃銅紫銅對(duì)于我國(guó)銅產(chǎn)業(yè)的發(fā)展，具有非常重要的意義。 </p> <p> 黃銅是由銅和鋅所組成的合金。如果只是由銅、鋅組成的黃銅就叫作普通黃銅。黃銅常被用于制造閥門、水管、空調(diào)內(nèi)外機(jī)連接管和散熱器等。黃銅以鋅作主要添加元素的銅合金﹐具有美觀的黃色﹐統(tǒng)稱黃銅。銅鋅二元合金稱普通黃銅或 </p> <p> 稱簡(jiǎn)單黃銅。三元以上的黃銅稱特殊黃銅或稱復(fù)雜黃銅。 </p> <p> 紫銅就是銅單質(zhì)，因其顏色為紫紅色而得名。各種性質(zhì)見銅。紫銅就是工業(yè)純銅，其熔點(diǎn)為1083℃，無(wú)同素異構(gòu)轉(zhuǎn)變，相對(duì)密度為8.9，為鎂的五倍。比普通鋼還重約15%。其具有玫瑰紅色，表面形成氧化膜后呈紫色，故一般稱為紫銅。 </p> <p> 它是含有一定氧的銅，因而又稱含氧銅。毛細(xì)紫銅管執(zhí)行什么標(biāo)準(zhǔn)？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鹽城直銷毛細(xì)紫銅管批發(fā)價(jià)格,毛細(xì)紫銅管"
