不锈钢钢管的概念
不锈钢钢管是一种中空的长条钢管材,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,在抗弯,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.
钢管的分类: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.
无缝不锈钢钢管也称不锈钢无缝钢管,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.
304不锈钢钢管全称SUS304不锈钢钢管
SUS304不锈钢管属于美国牌号材质的不锈钢钢管,国内牌号相当于0Cr19Ni9不锈钢钢管,通常用0Cr18Ni9替代.
不锈钢防锈的机理是合金元素形成致密氧化膜,隔绝氧接触,阻止继续氧化.所以不锈钢并不是“不锈”.
304不锈钢钢管材料出现生锈现象,可能有以下几个原因:
1.使用环境中存在氯离子.
氯离子广泛存在,比如食盐,汗迹,海水,海风,土壤等等.不锈钢在氯离子存在下的环境中,腐蚀很快,甚至超过普通的低碳钢.
所以对不锈钢的使用环境有要求,而且需要经常擦拭,除去灰尘,保持清洁干燥.
316和317不锈钢(317不锈钢的性能见后)是含钼不锈钢种.317不锈钢中的钼含量略高明于316不锈钢.由于钢中钼的存在,使得该钢种总的性能优于310和304不锈钢,高温条件下,当硫酸的浓度低于15%和高于85%时,316不锈钢具有广泛的用途.316不锈钢还具有的而氯化物侵蚀的性能,所以通常用于海洋环境.
不锈钢钢管随着社会经济的发展,其应用也了越来越广泛的普及.必将在各个带来全新的改观.
不锈钢钢管的理论重量:W=外径-壁厚x壁厚x0.02491不锈钢钢管的记算方式外径-壁厚x壁厚 x0.02491.
本世纪初发明不锈钢以来,不锈钢就把现代材料的形象和建筑应用中的声誉集于一身,使其竞争对手羡慕不已.不锈钢不会产生腐蚀,点蚀,锈蚀或磨损.不锈钢还是建筑用金属材料中的材料之一.由于不锈钢具有的性,所以它能使结构部件地保持工程设计的完整性.含铬不锈钢还集机械强度和高延伸性于一身,易于部件的加工制造,可满足建筑师和结构设计人员的需要.
