Ammonia plant piping specification
Ammonia plant piping specification
(OP)
I just want to know what kind of pipes can be used for Ammonia plants with low temperature. One of our valued clients would like to know that, can ASTM A-106 with ANSI B-31.5 pipes work satisfactorily in ammonia plant.
Best regards.

There are some sections of some production units where high temp hydrogen attack will occur-- A106 /carbon steel is unacceptable there.

You will need to check you temperature range for A-106. The upper bounds of the temperature rnge will not be a concern, However you will need to confirm the lower temperature bound.
If you drop below -20F for 3/8" and thinner wall, you will either need to consider A333 (cold service material) or impact testing. The thicker your pipes get the higher the low temperature limits become.
We use A106 gr B and A53 gr B in all out ammonia plants.
A question properly stated is a problem half solved.
Always remember, free advice is worth exactly what you pay for it!
