管道和连接件
Pipe and Fittings

　　为了确定产品系统的额定压力，首先确定标题“最大非冲击性工作压力表”下面的管道与连接件塑料材质和所属目录(壁厚 - 参阅参考参数 - Schedule 80部件，第40页，连接件指南，补充资料)。然后，在表格中的小标题内找出所选连接方式所处位置，从特定的管道尺寸开始，沿着交叉参数值纵向栏往下找，直到栏的左下方。这就是对于所确定的管道系统，在22^oC温度下的最大非冲击性工作压力。
　　In order to determine the pressure rating for a product system, first find the plastic material and schedule (wall thickness–see Reference Data–Schedule 80 components on page 40 of Fittings Guide for additional information) of pipe and fittings in the heading of the Maximum Non-Shock Operating Pressure table below. Then, locate the selected joining method in the subheading of the table and go down the column to the value across from a particular pipe size, listed in the far left column. This will be the maximum non-shock operating pressure at 73^oF for the defined product system.

阀门，管接头和法兰
Valves, Unions, and Flanges

　　Chemtrol阀门、法兰和管接头的最大额定压力与通径无关，在22^oC温度下为150 psi. 对于其它所有热塑塑料管道部件，最大非冲击性工作压力与温度有关。温度为100^oF以上时，请参阅下表。
　　The maximum pressure rating for Chemtrol valves, flanges, and unions, regardless of size, is 150 psi at 73^oF. As with all other thermoplastic piping components, the maximum non-shock operating pressure is related to temperature. Above 100^oF refer to the chart below.
