P I P E管和T U B E管的区别文件编码（008-TTIG-UTITD-GKBTT-PUUTI-WYTUI-8256）P i p e管和T u b e管区别：Pipe管的通用技术条件为A530，Tube管的通用技术条件为A450，它们的主要差别如下：A530：壁厚用公称壁厚表示，壁厚的允许偏差±%，外径的允许偏差控制较松（如上偏差最小为0.4mm），对于扩口试验、卷边试验、硬度均没有要求。

A450：壁厚用最小壁厚表示，壁厚的允许偏差负公差位零，外径的允许偏差控制较严（如上偏差最大为0.4mm），对于扩口试验、卷边试验、硬度均有要求。

另外，每个Pipe管和Tube管本身的规范中也有自己的技术要求，使用时应仔细阅读。

对于一般管线中具体用Tube管还是用Pipe管，很难给出明确的界限，但对于胀接的换热器管、炉管、仪表的卡套连接管必须用Tube管，对于焊接的管子用Tube管和Pipe管一般都可以，由于Tube管的制造检验要求更为严格，可以用在压力温度更为苛刻的工矿，当然价格也较贵。

一般的钢管都用PIPE，管配件叫PIPEFITTING，管法兰叫PIPEFLANGESTUBE主要用于非金属的管，如各种软管等但是方钢管也叫SQURETUBE，而PVC和PP材料的管又叫PIPE，搞得我们都有点糊涂了管子（按照配管标准规格制造的）PIPE管子（不按配管标准规格制造的其他用管）TUBETUBE可以是任何截面形状,PIPE要是圆的.但是我见到的很多圆管也叫tube，是否还有直径区别，我见到的是小管径圆的软管，油管等也叫TUBEPIPE用在硬管方面多些,TUBE一般在塑料或者软管的情况比较多!ASME在制定这段规则时，着眼于管子或管道用途的性质。

在锅炉和压力容器范围内，tube主要着眼于内外传导热量、热交换用途，而pipe则主要立足于将受压介质从一个地方输送到另一个地方的功能，这样pipe性质的管子上一般还都连着各种附件（三通、弯头）和阀门。

ASME标准-管道压力管道设计常用ASME标准，其中包括组件尺寸型式标准和材料标准。

组件型式标准规定了组件的型式、系列、尺寸、公差、试验要求，以及该组件可采用的材料标准等。

材料标准规定了适用的对象、原材料品种、化学成分、机械性能、制造工艺、热处理、无损检查、取样和性能检验、质量证书、标志等。

常用的组件型式标准包括钢管、管件、阀门、法兰、垫片和紧固件。

例如，钢管常用的标准有ANSI/ASMEB36.10M和ANSI/ASMEB36.19M；管件常用的标准有ANSI/ASMEB16.9、ANSI/ASMEB16.1和ANSI/ASMEB16.28；阀门常用的标准有ANSI/ASMEB16.34、API599、API600、API602和API609；法兰常用的标准有ANSI/ASMEB16.5、ANSI/ASMEB16.36、ANSI/ASMEB16.42和ANSI/ASMEB16.47；垫片常用的标准有ANSI/ASMEB16.20和ANSI/ASMEB16.21；紧固件常用的标准有ANSI/ASMEB18.2.1和ANSI/ASMEB18.2.2等。

材料标准主要集中收录在ASMEIIA篇铁基材料，B篇非铁基材料，C篇焊条、焊丝填充金属，D篇性能，以及一些增补内容。

与压力管道设计相关的典型的为A篇、D篇等。

A篇的主要分类有：钢板、薄板和钢带，公称管（Pipe），管子（Tube），钢法兰、配件、阀门及零件，压力用钢板、薄板和钢带，结构钢，钢棒材，钢螺栓材料，钢坯和锻件，钢铸件，耐腐蚀钢和耐热钢，锻轧铁、铸铁和可锻铸铁，以及方法标准等。

这些材料标准规定了原材料品种、化学成分、机械性能、制造工艺、热处理、无损检查、取样和性能检验、质量证书、标志等。

材料的表示方法通常使用“标准号-级别”及UNS编号。

例如，304是一种级别，而TP316中的TP表示管材，代表英文单词TUBE&PIPE的首字母。

F316中的F表示锻件，是FORGING的缩写。

NPT- National Pipe Taper Threads - ANSI B1.20.1国家螺纹管标准ANSI B1.20.1Characteristics of NPT (also known as ANSI/ASME B1.20.1 Pipe Threads, General Purpose):该标准规定:tapered thread 1o 47' 锥形螺纹1度47分truncation of roots and crests are flat 顶部和根部的截断面是平的60o thread angle 60度的螺纹断面角pitch is measured in threads per inch 单位罗纹数以每英寸计算Note! Pipe sizes do not refer to any physical dimensions. The outside diameter of a pipe or fitting must be measured and compared to a table for size identification. A 3/4" NPT pipe thread has an outside diameter - OD - of 1.050 inches.备注：管的尺寸不是指物理容积。

管的外部直径和属性必须以下面这个表格来确定。

例如：一个标准为3/4" NPT的管外部直径为1.050英寸。

Each thread size has a defined number of threads per inch - TPI, or pitch. The 3/4" NPT pipe thread has 14 threads per inch. Both the TPI and OD of the thread are required for positive identification of thread size because more than one size have the same TPI.每种罗纹管每英寸有固定的罗纹数（单位的罗纹数）。
