合金管(Alloy pipe)是无缝钢管的一种,合金管分为结构用无缝管及高压耐热合金管。主要区别于合金管的生产标准及其工业,对合金管进行退火调质改变它的机械性能。达到所需要的加工条件。其性能比一般的无缝钢管多变利用值较高,合金管化学成分中含Cr比较多,耐高温、耐低温、耐腐蚀的性能。普碳无缝管中不含合金成分或者合金成分很少,合金管在石油、航天、化工、电力、锅炉、军工等行业的用途比较广泛的原因因为合金管的机械性能多变化好调整。

合金管的材质大致有:16-50Mn、27SiMn、20-40Cr、12-42CrMo

合金管的分类:
钯合金管用于氢气与杂质的分离。
钯管纯化氢的原理是,在300—500℃下,把待纯化的氢通入钯管的一侧时,氢被吸附在钯管壁上,由于钯的4d电子层缺少两个电子,它能与氢生成不稳定的化学键(钯与氢的这种反应是可逆的),在钯的作用下,氢被电离为质子其半径为1.5×1015m,而钯的晶格常数为3.88×10-10m(20℃时),故可通过钯管,在钯的作用下质子又与电子结合并重新形成氢分子,从钯管的另一侧逸出。在钯管表面,未被离解的气体是不能透过的,故可利用钯管获得高纯氢。虽然钯对氢有独特的透过性能,但纯钯的机械性能差,高温时易氧化,再结晶温度低,易使钯管变形和脆化,故不能用纯钯作透过膜。在钯中添加适量的IB族和Ⅷ族元素,制成钯合金,可改善钯的机械性能11.汽车半轴套管用无缝钢管(GB3088-82)是制造汽车半轴套管及驱动桥桥壳轴管用的优质碳素结构钢和合金结构钢热轧无缝钢管钯合金中,银约占20—30%,其他成分(如金等)的含量<5%。
当前应用的钯合金中,银约占20—30%,其他成分(如金等)的含量<5%。氢透过钯合金的速率与温度、膜的厚度及渗透摸两侧的原料氢和纯氢的压力差(P)有关。升高温度,增大P及减小膜的厚度,会使透氢速率增加。但温度升高,将使渗透膜的抗拉强度降低。因此,钯管的使用温度通常控制在450℃左右。某些杂质可导致钯中毒,使透气性能变坏,甚至可使膜遭到破坏。能引起钯中毒的物质有:汞、砷化物、卤化物、油蒸气、含硫和含氨物质以及粉尘等。钯合金可制成管状(称为钯管)或膜片(称钯膜)。
ABS合金管及专用冷熔胶就是其中之一广泛使用于建筑给水和中央空调特别在建筑给水立管和中央空调用管中应用具有.PC/ABS合金也可以制作汽车外装件,如汽车车轮罩、反光镜外壳、尾灯罩等。PC/ABS具有良好的成型性,可加工汽车大型部件,如汽车挡泥板。
合金管作为钢铁产品的重要组成部分,因其制造工艺及所用管坯形状不同而分为无缝钢管(圆坯)和焊接钢管(板,带坯)两大类。
钯管纯化氢的原理是在300—500℃下把待纯化的氢通入钯管的一侧时氢被吸附在钯管壁上由于钯的4d电子层缺少两个电子它能与氢生成不稳定的化学键(钯与氢的这种反应是可逆的)在钯的作用下。
