What is SCH80? What standard is it?
Exactly, SCH80 is one of the standard values of the thickness (SCH) of seamless steel pipes, guys.
These values include: SCH5S, SCH10S, SCH10, SCH20, SCH30, SCH40S, SCH STD, SCH40, SCH60, SCH80, SCH XS, SCH80S, SCH160, SCH XXS.
The SCH value indicates the approximate value of the expression:
SCH = 1000 * P/S
In there:
- P is the pressure (PSI)
- S is the allowable stress (PSI)
According to the above formula, we can see that the allowable stress of a steel pipe is constant. It depends entirely on the grade of steel used.
With the required SCH value of 80, the brothers can completely calculate the working pressure that the steel pipe can withstand. At the same time, how much is the value of the pipe thickness needed for that purpose?
So what is SCH 80 cast steel pipe?
=> This is the common name of all manufactured steel pipes, whose thickness is manufactured according to the number SCH80.
That’s the thing!
Standard SCH80. Seamless Steel Pipe
There are quite a few brothers when buying at Tiger Steel or asking: What is the standard of SCH 80 seamless steel pipe?
In fact, any SCH-valued steel pipe is manufactured according to the same standards, guys.
The only difference is the purpose of use, so it will require different testing when manufacturing.
And there are only 4 main standards for the production of seamless steel pipes. That is:
- ASTM Standard
- API standards
- DIN/EN Standard
- ANSI B36.10. Standard
However, in each standard, there are many other small standards, Tiger Steel did not add to this article, for fear that the article is too long, and it is not good for you to get confused.
So, you can see more standards for the production of seamless steel pipes and seamless steel pipes SCH80 here.
