Centrifugal casting as per ASTM A451?
Centrifugal casting as per ASTM A451?
(OP)
Hi All
I've recently been asked to quote my product with female threaded fittings (12 3/4") made by centrifugal casting as per ASTM A451. Normally I roll and thread (SS304) in house or buy a seamless tube and thread. What is the advantage to centrifugal casting over seamless tube? Costly? This is a new process to me so any details whatsoever would be appreciated.

How do you plan on putting the threads into the cast tube?

Thanks to both you and arunmrao for your replies. In answer to your question, we normally weld a fitting onto the tube. If we did casting of the fitting, we would thread it on a cnc lathe.
The reason for my question in the first place was specifications I saw from a job in Africa that asked for the threaded fittings to be either made from seamless thick walled tubing, centrifugal casting, or forging. I've never used forging or centrifugal casting and don't see any advantage to it unless, as Arunmrao mentioned, there is no seamless pipe of the required thickness.
