不锈钢无缝管
不锈钢无缝管（SMLS管）是通过冲孔加工实心不锈钢坯料，随后进行热精整或冷拔而制成的。由于没有焊缝，它具有优异的结构完整性、高耐压能力以及一致的金属学性能，这使其与焊接不锈钢管区别开来。 它是关键的高温、高压和腐蚀性工业系统中首选的管道材料。我们供应热精拉无缝管和精密冷拔无缝管，提供1号酸洗、BA光亮或抛光表面处理，具有严格的尺寸控制、均匀的壁厚和光滑的内孔，可确保流体、气体和蒸汽的稳定输送。.

不锈钢毛细管是一种超小直径的精密管材，也称为毛细管，广泛应用于流体控制、传感及微组件制造领域。我们供应无缝毛细管和精密焊接毛细管，均经过冷拔工艺处理，以满足严格的尺寸公差要求，确保内壁光滑且具有洁净的BA亮面。 与普通不锈钢管不同，毛细管具有极小的外径和薄壁，且圆度稳定、壁厚均匀。它可进行切割、弯曲、扩口、冲孔，并可定制为成品针管、探头管和仪器部件。 优异的耐腐蚀性、洁净的表面以及稳定的机械性能，使其成为高端工业和医疗领域首选的精密原材料。.
不锈钢方管，又称SHS方形空心型材，是由不锈钢带钢卷经冷成型和精密焊接制成。它兼具结构强度与装饰性外观，广泛应用于建筑装饰和轻型结构制造。我们的方管可提供焊缝打磨和抛光处理，以实现无缝效果，适用于外露装饰项目。 与圆形不锈钢管不同，方形空心型材具有规整的方形几何形状，易于组装、弯曲、焊接和切割。提供多种表面处理工艺，并贴有保护性PE薄膜，以防止在加工和运输过程中产生划痕。可选配防指纹处理和PVD彩色涂层。.
不锈钢焊接管（ERW直缝焊接管）是将不锈钢带材轧制成圆形空心形状，并进行电阻焊接而制成的。焊缝可进行磨平处理、固溶退火及无损检测，以确保性能稳定。 与无缝不锈钢管相比，其特点是尺寸精确、壁厚均匀、可提供大口径规格且成本具有竞争力。我们主要供应两大类产品：用于建筑装饰的装饰性焊接管，以及用于工艺流体输送的工业焊接管。 装饰级产品可提供表面PE保护膜；工业级管道则采用ET涡流检测对焊缝进行检测。支持HL、8K镜面、防指纹及PVD着色等多种表面处理选项。.
