The wall thickness deviation for steel pipe is the difference between the maximum wall thickness and the minimum wall thickness. But how much of this deviation will not affect the customer's processing? If the wall thickness deviation is too large, what will happen? Follow us to find out what the allowable deviation of the wall thickness for seamless steel pipe.

What is the wall thickness allowable deviation for seamless steel pipe?

According to the national standard for the wall thickness allowable deviation of seamless steel pipe, for example:

What is the allowable deviation of the wall thickness of the 25*5 seamless steel pipe?

Answer: The wall thickness S is 5mm, corresponding to the allowable deviation range of >3~10 -10%, S to +12.5%, then the allowable deviation of the wall thickness of 25*5 seamless steel pipe is 0.5-0.625mm.
