What materials are generally used for ammonia pipelines? Is degreasing required when installing pipes and accessories?

Copper cannot be used, as ammonia has a strong corrosive effect on it. Nowadays, many chemical companies prefer to use stainless steel as the material for manufacturing chemical equipment, with 18% chromium and 8% nickel stainless steel being the most common choice. In the past, carbon steel was also often used in chemical engineering designs, after all, it is much cheaper than stainless steel!

Choosing 316 stainless steel would work, but the price might be higher.

Well, what about referring to that **standard or specification?

I noticed that the design specifications for cold storage only mention 10 and 20# seamless carbon steel, with no mention of stainless steel
