[dursosono]

ASTM A252 Para 16.1 state that one tension test shall be made for each 200 pipe. If those pipes (200 joints) made from two or more raw material/ coil (each coil has one heat number), it is permissible to perform only one tension test? Or it shall be made tension test for each raw material/ heat number?

You need five tension tests due to five different heats of skelp used for a lot.
