If you are looking for the CB7Cu-1(17-4PH) large diameter seamless steel tubes which are customized, centrifugal casting should be your priority. 
Centrifugal casting is the technique suitable for custom projects no matter the quantity is large or small. The fine grain structures and non-porosities of centrifugal castings mean premium quality. 
The mechanical properties of centrifugal castings are almost equal to forgings. 
The dimension we could produce is as follows.
