不锈钢无缝钢

不锈钢管材的概念

   不锈钢管材是一种中空的长条钢材,大量用作输送流体的管道,如石油、天燃气、水、煤气、蒸气等,另外,在搞弯、抗扭强度相同时,重量较轻,所以也广泛用于制造机械零件和工程结构。也常用作生产各种常规武器、枪管、炮弹等。

    分类:钢管分无缝钢管和焊接钢管(有缝管)两大类。按断面形状又可分为圆管和异形管,广泛应用的是圆形钢管,但也有一些方形、矩形、半圆形、六角形、等边三角形、八角形等异形钢管。
    对于承受流体压力的钢管都要进行液压试验来检验其耐压能力和质量,在规定的压力下不发生泄漏、浸湿或膨胀为合格,有些钢管还要根据标准或需方要求进行卷边试验、扩口试验、压扁试验等。

无缝不锈钢管材也称不锈钢无缝管,是用钢锭或实心管坯经穿孔制成毛管,然后经热轧、冷轧或冷拨制成。无缝钢管的规格用外径*壁厚毫米数表示。

规格及外观质量 

1、规格:热轧管外径32630mm。壁厚2.575mm。冷轧(冷拔)管外径5200mm。壁厚2.512mm

2、外观质量:钢管的内外表面不得有裂缝、折叠、轧折、离层、发纹和结疤缺陷存在。这些缺陷应完全**掉,**后不得使壁厚和外径超过负偏差。

3、钢管的两端应切成直角,并**毛刺。壁厚大于20mm的钢管允许气割和热锯切割。经供需双方协议也可不切头。

4、冷拔或冷轧精密无缝钢管《表面质量》参照GB3639-83

无缝管工艺流程 

管坯——检验——剥皮——检验——加热——穿孔——酸洗——修磨——润滑风干——焊头——冷拔——固溶处理——酸洗——酸洗钝化——检验——冷轧——去油——切头——风干——内抛光——外抛光——检验——标识——成品包装

包装

GB2102-88规定。钢管包装分三种:捆扎、装箱、涂油捆扎或涂油装箱。
