What is the schedule of carbon steel NH3 welded pipe for sizes 2 to 10 inches?

The schedule of carbon steel NH3 (ammonia) welded pipe for sizes 2 to 10 inches is typically Schedule 40. This is because Schedule 40 is widely used in various industrial applications, including the transport of ammonia, due to its balance of strength and weight. The dimensions and wall thickness provided by Schedule 40 match the requirements for handling ammonia effectively, ensuring adequate pressure resistance and structural integrity.

Choosing Schedule 40 for carbon steel NH3 welded pipe means it can withstand the pressures involved in these applications while still being manageable in terms of weight and ease of installation. Other schedules, such as Schedule 10 or Schedule 20, have thinner walls that may not provide the necessary strength for high-pressure applications. Schedule 80, on the other hand, has thicker walls but would generally be used in special cases where higher pressure ratings are required. Therefore, Schedule 40 is the most appropriate and commonly utilized option for this range of pipe sizes in ammonia applications.
