sample drawing procedure


Dear gurus, in manufacture of steel pipe, we check the pipe dimension like length, diameter for every 10 pipes produced, 1 pipe will be tested for mechanical properties for every 500 pipes and chemical analysis will be done for 1 for every 1000 pipes produced.i thought of creating one insp plan with 3 operations like dimensional verification, mech verification, chemical testing. reg sample procedure I thought of assigning fixed sample 1 for 10, 1 for 500, 1 for 1000 for the characteristics of its operations. is there any better way doing this. can we use sample drawing procedure here. if we assign sample drawing procedure, then it will be applicable for all 3 opeartions which is not required. could you please advise how to use sample drawing procedure in this case. where exactly sample drawing procedure is used. please advise.
