Single Piece Centralizer Single Piece Bow Spring centralizer is constructed from one piece ensuring high restoring force, uniform hardness and shock absorption. The advantage of the single piece centralizer is that its smooth corner radius reduces friction ensuring that fluids can flow more easily without obstruction. If you have any question on casing centralizer, composite centralizer, hinged welded centralizer, aluminum spiral vane solid rigid centralizer and bow spring centralizer etc. We will give the professional answers to you. Features RatingAPI Specification 10D Standard Design features 1. Smooth bow profile overall 2. Non-welded 3. Made to gauge 4. Integral bow design for increased strength and performance 5.
