銅管具有良好的塑性，但強度不高，具有良好的導(dǎo)電性、導(dǎo)熱性、抗腐蝕性及抗大氣和淡水的腐蝕性能，但在海水中的耐蝕性較差。空調(diào)盤管一般采用紫銅管，用鋁片作其肋片，銅管外徑一般為10mm，壁厚為0.5mm。套管式冷凝器一般是一根大直徑的無縫鋼管內(nèi)套有一根或數(shù)根小直徑的紫銅管。銅管空氣冷卻式冷凝器一般用直徑為10到16mm，壁厚0.7至1mm的紫銅管彎制而成。在銅管及合金里，純銅的散熱**1好。一般來說，越純的銅合金散熱越好。銅合金紫銅、青銅、黃銅，紫銅的純度**1高，它的散熱效果**1好。實際上，都是用銅的材質(zhì)，重點還要看它的形狀，表面積，材質(zhì)反而不是**重要的了。

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)工藝簡單，生產(chǎn)效率高，成本低，發(fā)展較快。 </p> <p> (2)螺旋銅管：強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。但是與相同長度的直縫管相比，焊縫長度增加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，其熔點為1083℃，無同素異構(gòu)轉(zhuǎn)變，相對密度為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)紫銅管的規(guī)格表。宿遷直銷毛細(xì)紫銅管制造商</p><p style="text-indent:25px">電纜用高精密毛細(xì)紫銅管。淮安新型毛細(xì)紫銅管以客為尊</p><p style="text-align:center;"> <span
