Chemtrol产品的额定压力
Pressure Ratings of Chemtrol Products

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22oC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 73oF for the defined product system.

  1. 对于更加严酷的应用环境,需要一个补充校正系数。
    For more severe service, an additional correction factor may be required.
  2. DN200的CPVC三通,90o 弯头和45o 弯头额定压力为表中参数的一半。工厂采用玻璃和聚酯可以得到175 psi的额定压力。关于交货信息请咨询客户服务中心。
    8" CPVC Tee, 90o ELL and 45o ELL rated at 1/2 of value shown. Pressure rating of 175 psi can be obtained by factory overwrapping with glass and polyester. Consult Customer Service for delivery information.
  3. 建议间歇流体压力不要超过20 psi.
    Recommended for intermittent drainage pressure not exceeding 20 psi.

  正如前面所暗示,所有热塑塑料管道的压力都是温度的函数。对于22oC温度以上的管道和连接件应用,请参阅下一个表格“温度校正系数”。要确定在温度升高的情况下的最大非冲击性额定压力,只要用上表得到的基本额定压力乘以从上表下一栏里得到的校正系数即可。如果温度低于22oC,其额定压力与上表中的基本额定压力相同。
  As implied by the preceding, the pressure for all thermoplastic piping is a function of temperature. For pipe and fitting applications above 73oF, refer to the table at the top of the next column for the Temperature Correction Factors. To determine the maximum non-shock pressure rating at an elevated temperature, simply multiply the base pressure rating obtained from the upper table by the correction factor from the upper table in the next column. Below 73oF the pressure rating will be the same as the base pressure in the table above.

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22oC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100oF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 73oF. As with all other thermoplastic piping components, the maximum non-shock operating pressure is related to temperature. Above 100oF refer to the chart below.
