Seamless steel pipe schedule 40(sch40 wall thickness comparison table)
Hello everyone, Xiaojing is here to answer the above questions for you. Seamless tube sch40 wall thickness comparison table, sch40 wall thickness comparison table This is a lot of people don’t know, let’s take a look now!
- The wall thickness of sch40 is 3.91mm.
- sch represents the inch wall thickness series, and the series with s is dedicated to stainless steel.
- The serial number of the pipe wall is as follows: The pipe table number in ANSI B36.10 and JIS standards is; Schl0, 20, 30, 40, 60, 80, 100, 120, 140, 160.
- The table numbers of stainless steel pipes and tubes in ANSI B36.19 are: 5S, 10S, 40S, 80S.
- Extended data: The pipe table number (Sch.) is the ratio of the design pressure and the allowable stress of the material at the design temperature multiplied by 1000, and the value after rounding.
- Sch .=P/[ó]t×1000 (1-2-1), where P represents the design pressure MPa; [ó]t—the allowable stress MPa of the material at the design temperature.
- The wall thickness of American standard and domestic standard is quite different. Generally, two pressure grades of American standard CL.150 and CL.300 are used.
- When the temperature is not high, the two wall thickness pipes, SCH10S and SCH40, are generally used, and SCH80 and SCH40S are used for DN less than 50.
- Whether at home or abroad, Sch.XX is used to indicate the wall thickness grade of the pipe, and the national standard GB/T81631 HG20553 is also included. According to the difference of the outer diameter of the pipe or the size of the pipe, the wall thickness of different sizes indicated by the same pipe table number is different. .
