　　合金钢管具有良好的力学性能主要用途是用于电厂，核电，高压锅炉，高温过热器和再热器等高压高温的管道上及设备上，它是采用优质碳素钢，合金结构钢和不锈耐热钢做材质，经热轧(挤、扩)或冷轧(拔)而成，最大的优点可以 100%回收，符合环保、节能、节约资源的国家战略，国家政策鼓励扩大高压合金管的应用领域。目前我国合金管消费量占钢材总量的比重仅为发达国家的一半，合金管使用领域扩大为行业发展提供更广阔的空间。

　　根据中国特钢协会合 金管分会专家组的研究，未来我国高压合金管欧冠决赛买球长材的需求年均增长可 达 10-12%。合金管是钢管按照生产用料(也就是材质)来定义的，顾名思义就是合金做的管子;而无缝管是钢管按照生产工艺(有缝无缝)来定义的，区别于无缝管的就是有缝管，包括直缝焊管和螺旋管。
