西安304/316l不锈钢管换热管主要用于火力发电、化工、钢铁等行业的加热器更换304/316l不锈钢管，冷油器更换304/316l不锈钢管，冷水器更换304/316l不锈钢管，取样冷却器更换304/316l不锈钢管，抽气冷却器更换304/316l不锈钢管，换热器更换304/316l不锈钢管，轴封加热器更换304/316l不锈钢管，高压加热器更换304/316l不锈钢管，低压加热器更换304/316l不锈钢管，压力容器，空气冷却器等等。凝汽器(汽轮机凝汽器)304/316l不锈钢管换热管规格：直径Ф12～Ф76mm，壁厚0.2～3.0mm，长度分定尺和不定尺两种。常用的材质不锈钢管型号有：304、304L、316、316L、317、317L。
西安304/316l不锈钢管换热管是引进进口制管设备制造而成，质量与进口不锈钢管材相当或略强，焊缝金相组织与母材一样，强度等机械性能略好。由于不锈钢管带材厚薄均匀，表面光滑平整，其质量确比同种材质的冷拨、热轧无缝不锈钢管好。延伸率大于35%，并且硬度小，易于胀接。
西安304/316l不锈钢管换热管分类规格：不锈钢光管,不锈钢螺纹管,不锈钢波纹管,201不锈钢螺纹管,304不锈钢螺纹管,316L不锈钢螺纹管,不锈钢U形管,不锈钢翅片管等, 我公司自行开发研制的不锈钢管换热管是选用进口上等不锈钢钢管，不锈钢带材，冷拉、热拉成形及带钢，经过卷制、焊接、探伤、滚压、打磨、固熔、抛光等一条龙304不锈钢管、316L不锈钢管生产线加工而成；可根据用户的实际需要，生产不同管径、壁厚、长度形式等各种不锈钢管规格的管材。
西安华达不锈钢有限公司簿壁304/316l不锈钢光管具有以下优点：
1.凝汽器(汽轮机凝汽器)304/316l不锈钢管换热管传热性能好，由于不锈钢管壁可采用0.5-0.7mm的薄壁不锈钢管材，提高了整体换热性能，在相同的换热面积下，总体的304/316l不锈钢管换热管传热系数比铜管提高2.124-8.408％。
2.由于304/316l不锈钢管换热管材质采用美国标准AISl304、316l等上等不锈合金钢，使其具有较高的硬度，不锈钢管子的钢度也明显提高。因此，具有很强的耐高温蒸汽的冲击性能及抗振性能。
3.由于304/316不锈钢管子内壁光滑，使得其边界层流底层厚度减薄，既强化换热，又提高了抗结垢性能。
4.装凝汽器(汽轮机凝汽器)304/316l不锈钢管换热管工艺性能好，采用传统的胀管工艺，304/316l不锈钢管换热管外径公差与铜管一致，不需改变管板孔的加工公差，利于现场直接选用，特别方便老机组的304/316l不锈钢管换热管更换管束改造。
5.304/316l不锈钢管换热管经济实惠，在同等换热面积下，不锈钢管的成本约为铜管成本的80％左右，并可直接进行更换管束改造。
6.为了消除304/316l不锈钢管换热管焊接应力，在保护气体中以1050℃高温进行热处理。
7.所有304/316l不锈钢管换热管钢管均采用压差法进行泄漏检查，气压试验至1.0Mpa，5分钟无压降。
