<p>热扩是钢管的一种加工方式,是把小口径钢管加工成大口径钢管。热扩钢管比热轧钢管机械性能稍差一些。 限于钢厂无缝钢管规格有限,根据终端消费者的需要于是热扩钢管就诞生啦,热扩钢管规格型号随意性比较大,一般是根据客户的需要而制作的,热扩钢管就是我们常说的热扩管,密度比较低但是收缩很强的钢管,(无缝化钢管)都可以简称为热扩管。用斜轧法或拉拔法扩大管材直径的一 热扩钢管采用的二步推进式扩管机集锥模扩径技术,数字中频感应加热技术,液压技术于一机,以其合理的工艺、较低的能源消耗、较低的建设投资、良好的产品质量、宽范围的原料与产品规格适用性、灵活易变低投入的生产批量适应性,顶替了钢管行业传统的拉拨式扩径技术。由于在近期内难于解决大口径钢管的供给,热扩钢管成为解决我国大口径钢管短缺的重要产品来源。缓解了大口径钢管市场的供应紧张局面 <br />
我国现行热扩钢管生产标准:<br />
热扩无缝钢管:GB/T8163-1999 GB/T8162-1999 热扩有缝钢管(无缝化钢管):GB/T3092-2008。</p>
