FAQ: ASTM A312 TP304 pipe for food processing plants

Q: How often should TP304 pipes be replaced?
A: 10-15 years with proper maintenance (versus 3-5 years for carbon steel).

 

Q: Can TP304 handle acidic foods like tomato sauce?
A: Yes, up to pH 3.5 at ambient temperatures.

 

Q: Is seamless or welded better for sanitary applications?
A: Seamless preferred, but welded can be used if properly polished.

 

Q: What's the cost difference between TP304 and plastic piping?
A: TP304 costs 2-3x more initially but lasts 5x longer.
