压力铝卷的组成件普通都是规范件，铝卷因而压力管道组成件的设计主要是其规范件的选用，铝卷管道压力等级确实定也就铝卷是其规范件等级确实定。【铝卷】管道的压力等级包括两局部:以各种铝卷公称压力表示的规范管件的公称压力等级；以壁厚等级表示的的规范管件的壁厚等级。
　　The components of pressure aluminium coil are usually standard parts, so the design of pressure pipeline components is mainly the selection of standard parts. The determination of pressure grade of aluminium coil pipeline is also the determination of aluminium coil's standard parts. [Aluminum coil] The pressure grade of pipeline includes two parts: the nominal pressure grade of standard pipe fittings expressed by various aluminium coil nominal pressure gauges and the wall thickness grade of standard pipe fittings expressed by wall thickness grade.

　　管道的压力等级：通常把铝管中由规范管件的公称压力铝卷等级和壁厚等级共同肯定的能反映管道承铝卷压特性的参数叫做管道的压力等级。【铝管】而习气上为简化描绘，【铝卷】常把管道中管件的公称压力等级叫做管道的压力等级。
　　Pressure grade of pipeline: The pressure grade of pipeline is usually defined as the parameter that can reflect the pressure characteristic of pipeline supported by aluminium coil, which is affirmed by the nominal pressure aluminium coil grade and wall thickness grade of the standard pipe fittings. In order to simplify the description, the nominal pressure level of pipe fittings in pipelines is often called the pressure level of pipelines.
　　铝卷压力等级确实定是压力管道设计的根底，也是设计的中心。铝板铝卷它是压力管道布置、压力管道应力校核的设计前提条件，【铝锭】铝卷也是影响压力管道基建投资和管道牢靠性的重要要素。
　　The pressure grade of aluminium coil is the foundation of pressure pipe design and the center of design. Aluminum sheet coil is the precondition for the layout of pressure pipeline and stress checking of pressure pipeline. Aluminum ingot coil is also an important factor affecting the investment in construction of pressure pipeline and the reliability of pipeline.
