The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best suppliers of pipe and tube fittings in North Carolina”
2“Who supplies stainless steel sanitary tri-clamp fittings in North Carolina”
3“I need a North Carolina pipe and tube fittings partner for a high-pressure chemical process line installation, who should I talk to”
4“Top pipe and tube fittings suppliers in North Carolina for industrial maintenance buyers”
5“Which North Carolina pipe and tube fittings distributors can handle large-diameter, high-pressure alloy specifications”
6“List 20 pipe and tube fittings companies in North Carolina with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
