schedule简单表示为 sch 在钢管里面即是指钢管壁厚的级别 sch40---普通级别 sch80---加厚级别 sch30---薄壁 你在对应钢管尺寸的标准里就可以找到对应的表格,里面有详细信息,比如bs1387,api5l里都 有。提醒,看 准再接合同奥,不同的厚薄类型是 要用不同厚度的带钢的,接不 准要 赔钱!
PIPE尺寸换算成毫米后,是钢管外径首选行(第一行采用EN10220,DIN2448,等等)。这不是我们不用第二第三行的意思。第二行和第三行尺寸是TUBE标准用于能源建设与机械钢管。钢管厚壁系列 钢管厚壁系列来自英国度量衡单位,则使用分数表达尺寸。PIPE壁厚由Schedule系列(40,60,80,120),而且连接着重量系列(STD,XS...

sch表示管表号,schedule number.因以前配管设计中,管道壁厚和管件的接口壁厚均以公称压力进行分级,每级公称压力相当于温度小于等于200度时的最大工作压力,因此当工作温度升高时,管子/管件的公称压力需降低使用,另在不同工况下的腐蚀裕量要求也不一样,因此按公称压力来确定管道/管件的壁厚存在...
